Best Bitcoin Mining Pool with the Highest Payout Top ...

With full blocks and average fees above 150sat/byte Slush Pool and ViaBTC payout more than Bitcoin.com mining pool

Roger claimed his pool Bitcoin.com was the "world's highest paying mining pool".
To his credit, this claim is true in certain circumstances, however it is misleading and it's currently NOT true. It's only true if the block transaction fees are under 1.53061224 bitcoins. (~150sat/byte for full blocks)
Slush Pool and ViaBTC (on PPLNS) both pay 98% of the block reward plus the block transaction fees.
Bitcoin.com pays 110% of the block reward and keeps the block transaction fees.
Over the last 24hours the average block transaction fees were 1.78648863 so directing your hashpower to Bitcoin.com would not have paid the most.
I realise Roger has to promote his pool but the gimmick "world's highest paying mining pool" is currently false.
Here's the maths (x is the fees):
Bitcoin.com = Block Reward * 110% = 12.5*1.1
Slush = (Block Reward + Fees) * 98% = (12.5+x)*.98
Bitcoin.com = Slush (calculate value of x (fees) for equal payout)
12.51.1 = (12.5+x).98
13.75 = (12.5+x)*.98
13.75/.98 = 12.5+x
14.03061224 = 12.5 + x
1.53061224 = x

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Actual cost of a 51% attach, $10.2 million

So I was discussing this last week and honestly it all felt too simple, so I'm trying to get some stronger counterpoints to this argument. Goes something like this.
You have some pool miner that wants to do a 51% attack. Lets assume the attack has three phases, the first phase is to try to accumulate 51% of the hashing power, next is the accumulation of more hashing power by ejecting other pools from through reorg. Finally when they aquired enough mining power they could blacklist exchange hotwallets or all manner of nefariousness. Lets further assume that everyone will act purely in their own self interest. For simplicity lets call the attacker "Spectre Pool".

Accumulation Phase

Assuming Spectre Pool can hit something like 41% of the hashing power, the first goal is to accumulate more resources to hit 51%. Since pool mining is a commodity market, all Spectre has to do in this imaginary world is offer more than the market rate. Since they are already at 41% hashrate, they need to entice another 10% of the market to come to their pool. The obvious way to do this would be to offer a "new customer bonus" or something like that. Some promotion where they pay 1% above market price for the hashing power of pool members. So, given a network hashrate of 116.73 EH and a market rate of 0.101 USD/TH per day, the cost they would have to bear to offer a 1% promotion to entice 10% of the network would be:
116.73_EH / 0.101_USD/TH * 10% * 1% = 1,155,742 USD per day for each 1% "bonus"
So, assuming they were willing to spend that much on "marketing", and that all miners worked in their own self interest, eventually they could lure enough miners over to achive 51%. Once they hit this threshold they could scale back on the "marketing" and thus reduce their daily burn.

Acceleration phase

Once at 51%, the next attack of Spectre will be to put their smallest competitor out of buisness. Lets call that the "Bond Pool", and pretend that Bond has 1.5% of the network hashing power. To put Bond out of buisness, with 51%, Spectere will need to reorg whenever Bond wins a block. By reorging to a chain without Bond, this will put Spectre one block behind and they will need to catch up. Once the reorg begins, Spectre will need to produce the longest chain on its own while starting one block behind. So we need to determine how long (statisticly) it will take Specter to produce n+1 blocks and compare that to how long (statisticly) it will take Bond to win one block.
Although this can be hammered out in an iterive calculation, a better approach will be an algebraic solution. Lets walk through the equations:
You can put the following into a GeoGebra CAS calculator to substitute and simplify the equations
solve(n*m = s*(n+1), n) M = 1/2-d S = 1/2+d m = t/M s = t/S solve(n*m = s*(n+1), d) n = s/(m-s) b = m*M/p solve(b = s*(n+1),p)
This will produce the following equations for the values we are interested in.
m(t,d): t/(1/2-d) # from `m` define s(t,d): t/(1/2-d) # from `s` define n(s,m): s/(m-s) # from `n` solve d(n): 1/(4*n+2) # from `d` solve p(d): 2*d # from `p` solve b(t,p): t/p # from `b` define
Plugging the equations into excel produces the following (assuming t=10)
n d p m s b
25 0.98% 1.96% 20.40 19.62 510
20 1.22% 2.44% 20.50 19.52 410
15 1.61% 3.23% 20.67 19.38 310
10 2.38% 4.76% 21 19.09 210
5 4.55% 9.09% 22 18.33 110
4 5.56% 11.11% 22.50 18 90
3 7.14% 14.29% 23.33 17.50 70
2 10% 20% 25 16.67 50
1 16.67% 33.33% 30 15 30
So once d=0.98%, Specture will have 50.98% of the hashing power, allowing him to eject 1.96% of all blocks mined at will. Of course this is all statistical, so Spectre will want some margin for randomness. So it would make sense to attach 1.5% of the blocks when Spectre reaches 51%
So once Spectre reaches 51% he has enough hashing power to prevent any of Bonds blocks (1.5%) from being included. Spectre can win a reorg (statistically) every 8.5 hrs and Bond can only produce a block (statisticly) every 11.1 hours. So once this attack starts, Spectre simply flashes his promotion to lure the miners in the Bond pool (who are receiving no reward) over to the Spectre pool. If he only gets one third of them, then he can increase his influence to 52%
Doing the same math again, with 52% Spectre can ice out any pool who has up to 4% of the hashing. Then running the promotion, Spectre will try to get 40% of the "homeless miners". Now Spectre's power grows to 55% giving him the power to ice out 10% of his competitors. This can cascade on and on until Spectre is the only public pool left.
Now, at 51% the attack and reorgs take many hours, but as more and more pools get targeted, more and more miners will jump ship and end up at Spectre so long as they can hold the promotion. Bond's only choice would be to either close up, or leverage everything and mine at a loss for weeks hoping that Spectre eventually drops below the threshold for his attack.
Of course Spectre has even more tremendous expenses. To offer the 1% promo to 10% of the network would cost Spectre $1.16 million / day, or 3.52 million per month for each percent of miners it lures over. So going from 41% to 61% would cost Spectre $70.3 million / month, but at that point he can attack 20% of the network giving him a reach of about 80% which is pretty much the entire pooled mining capacity today. Seems like $70 million is a small price to pay to buy the entire bitcoin network.
Other expenses Spectre would accrue would be related to the attacks and reorgs. The early attacks will take hours and throughout Spectre needs to continue payouts to the pool even though he is generating no BTC durring the attack. So long as his chain is orphaned, his blocks have no value. Only after the attack and reorg when his chain becomes longest will he be able to claim the block reward for all the blocks he minded. This (in my opinion) will the the hardest challenge. The first attack and 25 block reorg will require Spectre to put his entire 51% hashing power on an orphaned chain for 8 hours requireing $208.6 million in payouts. Once he wins the attack and the chain reorgs he can cover his expeses with the block reward, but borrowing $208 million for 8 hours is still a very difficult thing to pull off. The interest alone on the attack is over $40,000 (20% interest compounded continually). Below is a table of the calculations
Specte Bond Promo Cost Hrs Blks Levrg / Block Reorg Leverage Rate Int Cost
51.00% 1.50% $1,155,743 8.497 25 $8,025,990 $208,675,743 20% $40,485
51.50% 2.50% $1,232,745 5.825 17 $8,025,990 $144,467,822 20% $19,215
52.50% 4.50% $1,336,143 3.492 10 $8,025,990 $88,285,891 20% $7,039
54.50% 7.50% $1,562,998 2.141 6 $8,025,990 $56,181,931 20% $2,746
58.50% 14.50% $2,023,385 1.140 3 $8,025,990 $32,103,960 20% $835
66.70% 33.30% $2,970,442 0.500 1 $8,025,990 $16,051,980 20% $183
Of course, once Spectre gets 2/3 of the hashing power he controls the entire chain since he can include or exclude any block he wants. So this "Total Self Interest" simulation of a 6 day attack puts Spectre's expenses at $10.3 million in promotions and $71,000 in interest, or about $10.4 million total.
1 - All "hashes" are hashes per second
2 - TH = 1012 or 10004 hashes per second
3 - EH = 1018 or 10006 hashes per second
4 - Assume a market rate of 0.101 USD / TH / day
5 - Assume an average daily network hashrate of 116.73 EH

THE END OF ALL ASIC MINERS? - Monero's New Superweapon: "Time Locked Proof of Non-ASIC work challenge reward" algorithms.

I propose the following algorithm to end this War of attrition with ASIC / FPGA manufacturers , hopefully once and for all and save us Precious PoW Tweaks during the upcoming forks.
"A time-locked, Proof of 'Non-ASIC work' Challenge reward algorithm"
Here's an image to help you visualise how the algorithm works (details below):
https://imgur.com/a/9S8dA
Here's why we need it:
ASIC manufacturers mine in Secret to attack our decentralized network. They'll win the war since they'll 'get their investment back' before we brick their ASICs, allowing them to launch never-ending attacks against our decentralization, for eternity.
Quick Overview
This algorithm uses the concept of "time-locked reward challenges".
The algorithm ‘time-locks’ the reward, then issues a ‘non-ASIC’ work challenge during each regular PoW Fork, which distributes mined rewards only to CPU and GPU miners who can pass the challenge and prove they are not ASICS, by maintaining their hashrate during the ASIC downtime.
These Hash-rate challenges after PoW Forks successfully ‘detect’, and ‘Severely Penalize’ anyone Mining with an ASIC/FPGA, even those in Secret.
Proof of Concept: An Actual Demonstration
I'll demonstrate this algorithm in action:
Please see this image to help you Visualise how the algorithm works:
https://imgur.com/a/9S8dA
There is a critical flaw and uniquely identifying feature that exists in absolutely 'ALL ASIC and FPGA miners', even those mining in Secret.
As most of you may know, with the upcoming V7 PoW hardfork,
Instead of just destroying an ASIC with a fork, we can further exploit this to attack the ASIC Manufacturer or Miner by taking back all their mined rewards and giving them to the community
The Special timeframe is PoW Fork + 'N' Days. ('N' being however many days remaining where it would be "impossible" to build and startup a new ASIC/FPGA after the fork.)
To exploit this, the algorithm introduces a period of time called the "Mining Rewards Collection Timeframe" (MRCT), the time period in between regular PoW Hardforks. the grey shaded area in this image
This "Mining Rewards Collection Timeframe" is a time whereby all mining profit rewards are 'time-locked' or held hostage in escrow, on either the mining pool, or on the Actual Blockchain code itself, or Both, depending on where this algorithm is eventually deployed.
The algorithm stores the wallet address a mining reward belongs to, and the maximum hash rate (or maximum value adjusted share rate per day) observed during the "Mining rewards collection timeframe" for that particular wallet address.
This "Mining Rewards Collection Timeframe" can be of any duration as required by the developers; 1,2,3,4,5,6 Months or longer . The longer This Timeframe, the more dangerous it is to ASIC miners. Meaning we don't have to rush with forks.
Since it's time-locked, mined coins/rewards cannot be cashed out until the coming challenge; However, mining pools can still choose to payout smaller miners before that time if they have a 'good stable Non-Asic Hash challenge passing history', or a deposit on file, or at their own risk, so most good miners don't have to wait to cashout rewards!. Big miners on the other hand, won't care! Why? Because the delay doesn't cost them anything. (it's a TINY TINY inconvenience compared to the damage ASICs would do to GPU mining profits. I hope this makes sense)
Now for the Critical ANTI-ASIC Work Challenge.
Time passes and the mining rewards collection timeframe ends with a Hardfork that changes the PoW algorithm slightly,
All ASICS and FPGAs are INSTANTLY destroyed.
At the same time, the mining rewards from that collection timeframe are now ready to be paid out.
Since only the CPU / GPU miners are able to hash normally,
The Algorithm now issues a Hash Rate challenge to determine how much of the coins mined were actually mined by ASIC or FPGA miners.
The challenge is nothing special. Miners just have to leave their miners running normally at maximum speed for the period of the challenge, same as they do everyday!
During this challenge, their "Average Maximum Hash rate during the challenge" is compared to the "Maximum Hash Rate speed" recorded on the blockchain during the Mining Rewards Collection Timeframe.
See the green dotted line in the image
Thus at this point, since ASICs are DEAD, they cannot Hash at the same rate during this challenge period, so any significant difference in hashrate would thus clearly indicate the use of an ASIC or FPGA miner.
Now, we have all the information we need to STRIP ASIC Miners of ALL their gains, and Reward GPU miners instead.
As shown in the earlier image
What if a 1 GPU breaks in a 12 GPU mining farm during the challenge? (Very rare) or for some reason, you can't mine during that period? then the miner can simply rent the GPUs from nicehash for the Challenge. An ASIC miner however, cannot use this strategy (because ASICS are not GPUs, explained further below). Also we can implement a 2nd chance option; the confiscated reward may be frozen for the next Cycle; and the miner may get a 2nd chance to prove the hashrate again, with a % reward penalty.
The Beautiful thing is that If ASIC miners fail the challenge, Everyone gets a Bonus share of the Reward Forefitted by the ASIC miners, So Everyone wants the ASIC miners to fail so they get Free extra money. and thus have a financial reason to support this algorithm.
*There is no escaping it... or is there?
Is it ASIC PROOF? Can you Cheat this algorithm?
I've also tried to see if you can work around this algorithm:
  • Example 1: What if they switched in GPUS to mine for an ASIC during the challenge? Well, that wouldn't work. When the challenge comes, they can either save the rewards mined by the GPUs, or save the rewards mined by the ASICs, One will always be lost and result is the same anyway because you'd only get paid for the Hash rate of the GPU. The ASIC portion of the hash rate will ALWAYS be lost.
  • Example 2: What if they use the GPUs to mine a different coin and have them only hash for the ASIC during the challenge period?
  • Consider the Antminer X3. at 200KH/s, to support just "ONE ASIC", they would need over 200 RX 580 Cards or 100 VEGA cards to pass the challenge... costing well over $60,000 (SIXTY THOUSAND DOLLARS) and if they depreciate at ~ 10~15% a year, they'd lose $6000~$9000 a year. it's not enough to cover your losses,
  • Also, What other coin could you mine? If ASICS are so powerful, there won't be another coin except those running this algorithm. Then, the dev can choose to issue the challenge at the same point as the other coin using the same algorithm, so they lose all rewards from one coin as 1 rig cannot sustain two challenge algorithms at the same time.
  • Example 3: What if they just leave some GPUS on standby to avoid the power costs? Then ASIC's would still be unable to be mass produced anyway. Because for every ASIC Mass produced, you'd need to Mass Produce 200 times the GPUS to support them in their place, and own of all them. practically impossible.
  • Example 4: What if they rented hashing power from Nicehash to fill in during the Challenge period?
  • Yes, but so can we! The beautiful thing about this algorithm, is if we rent the limited hashing power on Nicehash first before them at break even or loss, it doesn't matter, Because, the ASIC miner cannot rent and hash rate and will fail the challenge, and Forefit the ENORMOUS amount of Rewards to the community. Imagine, Mining at such a high rate for months on end , the rewards confiscated and paid to GPU miners will easily offset any of the tiny losses renting hashrate from Nicehash, so ultimately, The ASIC miners lose Everything, and the community (you and me) gets all their money.
  • Also if ASICs Dominate the crypto market, there won't be any GPU to rent, all remaining coins would be mining this algorithm, meaning they would have to save their own hashrate for themselves, not rent it to ASIC miners. otherwise they lose their reward. Brand new users may rent their GPU's but its no where near enough to cover the ASIC hash shortfall in the challenge.
  • Example 5: What if they waited till we exhausted our supply of PoW fork tweaks? That's the beauty of this algorithm!. We don't actually have to tweak the PoW algorithm on a constant basis! We can intentionally leave it the same. So Everyone passes the Challenge, Then when we do detect an asic "trying to Mine their Money Back in secret (as they do now)", We tweak the PoW at the Next Hardfork. Destroying and bankrupting their very first attempt, and we get all their money and rewards, So there's no need to waste a PoW tweak in a pre-emptive strike, because the rewards are Time-Locked to the future. We can lie in wait with a single PoW like a Trap, and eat them alive (literally we get all their rewards after the challenge!). We can maintain this lethal threat to ASIC manufacturers without having to change the PoW at all!
And remember, all this effort is just for ONLY, ONE ASIC. meaning you Can't mass produce it.
So ultimately it wouldn't even make sense to even develop an ASIC, as you'd be far more profitable just mining only with the 200+ GPU's required to cheat the algorithm.
*So in summary, *
  • No ASIC/FPGA miner can escape the challenge. Not even those running in secret.
  • All ASIC miners are guaranteed to suffer a huge (possibly fatal) financial loss, with no prospect of any return on investment. Time locked rewards ensure No secret pre-mining with ASICs is possible. ASICs are destroyed with each challenge, all R&D and manufacturing costs and the electricity bill used to power them is wasted for basically "ZERO returns",
  • …..and lets not forget that all their rewards gets given away to other honest miners like you and Me!. ( LOL!) or potentially the developers of the fork :)
  • As long as the algorithm is active and used by multiple coins, no ASICs will ever exist to mine in secret,
  • We save precious PoW tweak changes, since there's no need for a pre-emptive PoW strike to prevent 'ASIC hit and run' pre-mine scenarios.
  • ASIC manufacturers see that the war is un-winnable and go invest in other things,
So, in theory, The War Ends. (at least for a very good part of the future)
As they say: " Don't build a wall and hide in fear.... Build a wall and launch missiles from behind it against the enemy so they will never dare attack us again."
I would like to point out that time locked reward challenges are already in use by the Olympic games to Strip drug cheats in the past by storing samples and testing them in the future, and it's also in the PPLNS minig pool algorithms to deter pool hopping cheats, and also in the Bitcoin's Lightning network in the form of decrementing time-locks" that 'enforce the transfer of funds' under certain conditions.
Is it beautiful? Will it work? Can it be done? Let's discuss this

Bitclubnetwork switches to Bitcoin Cash on February 1st.

Find below their annoucement.
"Date: 11th of January
Change to Bitcoin Cash February 1st! GPU buyback starts on February 1st No more ClubCoin Virtual Staking Hardware Wallet sales on hold Bitcoin Gold Wallet goes live on January 17th Ethereum withdrawals delayed - new system Monero Upgrades - New System
BitClub switches to Bitcoin Cash on February 1st
This is one of the most important decisions we have ever made ... Please read and share!
We have reached a point where the Bitcoin Blockchain (BTC) has become a major burden. It's slow, it's expensive, and it costs our business and, more importantly, our members (YOU) tens of thousands of dollars a day in transaction fees.
We hoped that a scaling solution would emerge, but that's not the case, and while Bitcoin continues to gain in popularity, it's no longer practical for a company like ours to accept it.
Since the beginning of the year, the average cost of a new member paying $ 99 for signing up is $ 17. We've seen times of $ 25 + and even some as high as $ 40, just to send Bitcoin for a bill. Ouch!
As a company we are mixed with this decision because Bitcoin is really great for miners right now. All of these high fees will be passed on to the blocks and eventually taken down into the pocket of each one.
Currently, each block contains between 4-5 Bitcoin (currently about $ 60,000- $ 75,000) transaction fees, which are included in the 12.5 reward. In some cases we hit blocks with 10+ BTC and the highest was 11.3 bitcoin in a block (block # 500756).
With so much profit, we will continue to pay Bitcoin mines and all mining wins in Bitcoin. However, we no longer accept Bitcoin for payments and all commissions are also paid in Bitcoin Cash.
What does that mean?
From February 1, we will not only accept Bitcoin Cash (BCH) Bitcoin (BTC), which means that you need to purchase Bitcoin cash from a stock exchange or wallet providers to register mining pools or buy. You can also convert your existing BTC to BCH, but either way it's just BCH!
We also pay ALL commissions in Bitcoin Cash!
For example, each binary cycle pays out $ 200 (about 0.013 BTC) bitcoins and the same $ 200 will be paid in bitcoin cash (about 0.08 BCH) as of February 1st. Nothing will change, you will still get exactly the same USD value for everything, but instead of being paid in Bitcoin, it will be credited to your Bitcoin Cash Wallet.
Convert BTC to BCH ...
We will make it very easy for you to convert your BTC to BCH and back to BTC as often as you like. In fact, you can do this within your back office with just a few clicks.
You will be exchanging your virtual balances and we will provide you with the current market price for the swap so that you can easily transfer part of your balance back and forth between BTC and BCH with zero fees.
Soon after we will do it for all other coins as well. So if you want to win Monero or Ethereum Classic and have Ether or BCH, you can easily use this feature to exchange them in your back office before you request a payout. Imagine this as an internal shapeshift
This feature allows you to maximize commissions and wallets with ZERO fees. It gives you full control of your balance and, most importantly, it will help you avoid the huge withdrawal fees on Bitcoin or any other blockchain that could be costly "

Beermoney Essentials: 6 Ways To Earn Passively With Cryptocurrencies In 2018

Hey guys!
This is my second "Beermoney Essentials" post. Here's the first one about Chrome Extensions if you missed it a year ago. These types of posts basically are just about things have seem to become 'essential' information in terms of Beermoney.
This post is going to be about Cryptocurrency. Cryptocurrency has been becoming more and more popular around the beermoney community, and I think it's safe to say that 2018 will be the year of cryptos.
Here's what this post is NOT. This post will not be the 'here's what cryptos I think you should buy and hodl in 2018'. This post IS going to be about cryptos you can get into and do whatever you want to without having to directly invest in them. So yeah, this post is mostly going to be about mining.

6 Ways To Earn Passively With Cryptocurrencies

Alright, so in this post, I'm going to split things up into 4 parts:

Part 1: GPU mining

Does anyone here remember Nice Hash? (I mean, it technically still is a thing actually). Nice Hash is/was a nice site that would allow you to use your PC to mine. I believe they actually mined ETH (I think), but they were nice because they paid out in BTC (which most people prefer). It was really the easy way for just about anyone to get into mining (assuming you have a decent GPU). Just a month or so ago they claim to have been "hacked" and they lost (at the time) ~$60 million in users' bitcoin. For whatever reason a lot of people wanted them to resume operating after the bits were lost, so they are back up. I won't recommend Nicehash at all. I don't think they were really hacked, and I do think it was an inside job. If you want to use Nicehash, you can. I just really don't recommend it, and there are plenty of alternatives. Here are just a few that I found.

WinMiner

WinMiner is a really neat alternative to NiceHash. From what it seems, the payouts on Winminer are a bit lower, but there are a couple advantages to using this site that might outweigh the lower payouts. First of all, Winminer is really easy to use, you can just download it and set it up, and it's all set. The thing about Winminer that is really nice is that you can get paid out in many different ways. If you want, you can cash out to Bitcoin, but they have a $100 minimum, and the fees are really high, so there's a good chance you won't want Bitcoin. Alternatively, you can withdraw your balance to PayPal, ETH, LTC, Amazon, or iTunes. One thing I don't necessarily like about Winminer is that it does keep your balance in USD at all times, so if you earn for a month and go to withdraw if bitcoin's price goes up 50% in that month, you won't get that bonus reflected on your total cashed out because it was in USD. It's probably not an issue for most people.

Kryptex | Nonref

I have been using Kryptex since just after the announcement of NiceHash being hacked. It has a nice UI and it is very customizable with its settings. This is probably the closest site to the original NiceHash. You can request a payout in Bitcoin any time after you have 0.0006 BTC. One thing about Kryptex is that it does have a referral system. You can earn 10% of your referral's earnings. I shamelessly put my referral link above. Feel free to give it a click if you want.
I don't really prefer this site over WinMiner because it doesn't offer quite as many methods of payments, but here it is anyways.

Part 2: CPU Mining

CPU Mining for Bitcoin has been dead for a long time, but there are still some ways to use your CPU to earn some crypto passively.

LoadTeam

LoadTeam used to be a site that would pay you to test loading websites in the background passively. It was never a lot of money (and it still isn't), but they made the change a few months ago to switch over to Crypto Mining. I actually didn't even notice the switch, but I checked my account after a couple months and I had a few dollars sitting there. LoadTeam offers instant paypal transfers with no fee for all balances over $1. It's pretty nice. I didn't even notice a difference in CPU usage over the last few months. I think of it as an easy couple dollars a month, and it runs entirely in the background.

CoinHive Monero Mining

You might have seen this around a bit. CoinHive is a service that allows sites to mine monero in the background(ish). Some sites have been using Coinhive as an alternate to advertising/adblockers. There are a few sites that have been adding coinhive to their site. You can run this passively in the background.
I don't know all of the sites that have CoinHive, but two big ones I know of are FreeBitco.in and CoinPot.
FYI, I think Freebitco.in links are blocked on reddit, but if anyone wants my referral link, send me a PM. I give 100% of my referral earnings back to my referrals.

Part 3: PoC Mining

Burstcoin Mining

PoC Mining you might not have heard of, but it's fucking cool. PoC = Proof of Capacity. While CPU mining uses a computer's CPU, and GPU mining uses graphics cards, PoC mining uses free storage to mine. The appeal of PoC mining is that it seems like everybody has free storage. Check around your house, maybe you'll find a nice external hard drive with some space on it. You can use this to mine from.
Now I know I said above that this wasn't going to be a post of me telling you what cryptos I recommend for you to invest in, but here's my quick pitch for Burstcoin. Burstcoin is the worlds first (and only) PoC coin. It is the "green" crypto. Mining Burstcoin takes up 400x less power than a crypto like Bitcoin. It's really pretty fucking cool, and I absolutely support the coin. Feel free to read more about Burstcoin on /burstcoin, and check out the recent announcement of Dymaxion.
But you're here to learn how to earn from PoC Mining passively.
Unlike CPU and GPU mining, it is a lot more hard to get into because there are a lot more steps involved to setting it up. You'll actually need to know how to 'plot' your storage and set up a mining pool.
I'm not going to write out the entire process because there are plenty of other resources to help you out.
One thing I really recommend is QBundle 1.6, which is probably the closest thing that will walk you through the process of setting up a wallet for burst and start plotting and then mining with your storage.
One thing I'll also point out is that in order to mine burst with a pool you will need at least one burst in order to set the reward recipient. There are faucets you can get a free burst from, but if you can't get the faucets to work, feel free to send me a PM and I'll send over everyone who wants to get into burst a coin to set the recipient.
Here's a video explaining burstcoin a bit more: https://www.youtube.com/watch?v=Fyj9RIyxLb4
If there are requests, I will happily make a video explaining how to get started mining with Burstcoin.

Part 4: Saving/Investing

Okay, I said this post wasn't about investing in cryptos, and that's not what this section is about, at all.
This part of the post is about using the cryptos you already have to earn more crypto. There are quite a few options in this space, but I do advise you to take all caution when investing your cryptos into anything. Realize that ANYTHING can become a scam when you're not holding your own private keys.

FreeBitco.in

I've mentioned this a few times in the past, but Freebitco.in allows you to use their site has a savings account/wallet and they pay 4.08% annual compounded interest per year on all your balances held (they pay interest daily). I've been hodling bitcoin on there on and off for quite a long while now and it's really nice. Another advantage I could point out is that their site does work as a wallet as well, and while bitcoin's fees are going crazy, you have the option of setting up an automatic weekly cash out (when you're ready to cash out your balance on their site) and the fee is just 3000 satoshi, or you can sign up for a 1-6 hour payment with a heavily reduced fee, or instant with a full average fee. It's really nice having those options.
Freebitco.in does offer a 25% referral bonus for all interest paid out on their site, and I wrote above:
FYI, I think Freebitco.in links are blocked on reddit, but if anyone wants my referral link, send me a PM. I give 100% of my referral earnings back to my referrals.
I have been paying 100% back for over a year now, and I don't plan on changing that.
Please remember: if you do deposit anything onto freebitco.in that is a risk you're taking.

Conclusion

There are a lot of different ways you can use Cryptocurrencies to your benefit. Even if you don't have a good CPU, GPU, or have much free storage, there are still options for you, and maybe you could even consider taking some of your profits from beermoney in 2018 and putting it into upgrading your own set up, or taking some profits and investing into the cryptos you support.

So I finally gave Honeyminer a try. (my personal semi-review)

This review was last updated 11-30-18
When I first was interested in trying this program I couldn't find anything about it. it seems a lot of people were too scared to try it since their is like no information about it other then from the web page itself. to be honest I was a bit scared to try it. I've tried many other software of this kind, on a "test" machine I'm not afraid to lose on a secondary network and router... incase its a scam or gonna give me a virus and I suggest anyone installing mining software do the same as a rule of thumb. please keep in mind the software is still relatively new and they are working to improve it still. They seem to be hiring as well if your interested in helping them grow by working for them look near the bottom for their contact e-mail. ____________________________________________________________________________________________________
This review is for the windows version of Honyminer Because its still relatively new I knew could go one of two ways "sacm software" like most every mobile mining app or even quite a few desktop ones - Or legit. I'm glad to say after using it for a month it seems legit. I was able to withdraw from it no problem. If your system is really crappy It might not work that well on your computer or mining rig. There are no ads and the program doesn't seem to disrupt any day to day activity at least not on my main system, however you can of course expect increased heat production of your system as with any mining software, adequate cooling is important in mining. Anyways Honyminer is as close to an easy one click mining software as I have come. they seem to be making a "pro" version too for more hardcore miners. They do take a fee which is to be expected *look near the bottom for fee information\* but that fee goes down significantly if you have multiple GPU's mining.. The good thing about it for me was it let me kind of set my rig to "autopilot" so to speak. If you wish to see the H/s numbers in real time, go to you settings and view the "expert logs" which will also tell what coin is being mined at the time ____________________________________________________________________________________________________________
Pros
Pro and or con (depending on how you look at it)
Cons:
_________________________________________________________________________________________________
COMPATIBILITY: (sorry it keeps adding asterisks to the card model for no reason)
WORKED ON: every nvidia card tested so far with card models dating back from 20014 to now..
Worked on some surprising low end and or old CPU and GPUs. like the
AMD Radeon R9 380 card in addition to a AMD Athlon II X3 450 Processor and it mines just fine.. of course that processor doesn't make much on its own lol.. but thats an extra 2 or 3 cents per day by itself. I've also tested it with an i3, i2 Most AMD cards worked but I ran into issues with a few so maybe it's easier for me to just tell you what did not work.
DID NOT WORK ON:
--- any of the AMD ATI Radeon HD 4250's tested so far (2) that particular card It didn't work at all for mining like never enabled the gpu but the cpu on that machine did work however it would generate an "error" on start up but otherwise did not disrupt the mining on that system except if I turned on idle earning mode, I would get a bunch of errors as it was trying to access the GPU. we need the functionality to enable or disable hardware individually I think. (errors or no errors it just seems like a good thing to have.)
OR a system that had both a AMD Radeon R7 Graphics and a AMD A8-7650K Radeon R7, (4C+6G) which surprised me considering some of the things that did work lol... but I think it might just might be that one system, but either way can't vouch that it will work. That system was pre-built and wont allow the parts to be changed or easily removed to be worth the effort since I have to use it for other things so unfortunately I can't test these on another mainboard at least not with wasting some time, money and patients that Id rather dedicate elsewhere for now.
I had some issues using one RX Vega 56 card but i think it's was just that card because another one did work just fine.________________________________________________________________________
FEES W/ comparison to nicehash
I'm not sure if this post will be helpful to anyone looking into this software or anyone whos looking to try a different mining software but if it dose great.
-- nicehash charges the following fees as far as "selling/mining" or withdrawing.
Payouts for balances less than 0.1 to external wallet 5%
Payouts for balances greater than or equal to 0.1 BTC to external wallet 3%
Payouts for balances greater than or equal to 0.001 BTC to NiceHash wallet 2%
Withdrawal fees from NiceHash wallet
Withdrawals from NiceHash wallet are subjected to the withdrawal fee, which depends on the withdrawn amount and withdrawal option.
WITHDRAWAL OPTION AMOUNT TO WITHDRAW FEE Any BTC wallet From 0.002 (min) to 0.05 BTC 0.0001 BTC
Any BTC wallet More than 0.05 BTC 0.2% of withdrawn amount
Coinbase More than 0.001 BTC FREE - No fee. but they also say Minimum Coinbase withdrawal limit is adjusted dynamically according to the API overload._____________________________________________________________________________
honyminer fees are based on number of GPU's working.
8% for 1 GPU or for 2 GPUs or more the fee is 2.5%.
The only withdrawal fee is the standard BTC transaction fee that bitcoin charges and it doesn't go to honyminer. When they add the other withdrawal functions that fee cam be avoided I suppose.
_________________________
Earnings: in comparison to nicehash
Update: sometimes software / test networks will give a view that can be off + or - a few percent compared to actual. A lot of different things can affect your earnings including where you are located in the world, I'm not sure how many of you uses more than one mining software day to day , ISP issues, crypto price fluctuation, updates to fee's, and inaccuracies in test software/networks can affect results. but I go back and forth between different ones from time to time and I think that's good practice to keep options open. I notice that honey miner seems to do better for me at night-time and early morning/afternoon is when it has the most trouble raking in the crypto's
That said I've been trying to test to see how this compares to nice hash earnings, with two of my buddies. So this is an average between the 3 of our profits vs loss compared to nice hash, I'm using a two 10 GPU/ 3 cpu setups, while one of my buddies is using two 1 gpu, 2 cpu setups and the other is using two 30 gpu mini farm's. We each have 2 networks each located relatively close by *less than .5 mile the furthest one* one with honyminer running and the other with nice hash and we are looking over 24 hour periods When all three of us have the results for one day, we average our results together. In all we will be looking over a 14 day period. UPDATE: the results below were done well long before the latest update to the software so I do not know if they have changed, Id have to do another round or perhaps some from the community could give me their results and save me a bit of work. I'm not sure when Id have the time to dig into it again. Sorry that it took me so long before I could get on here to post the results of the last few days of the tests.
Seem to be a bit smaller then nicehash at times and higher at other times. it seems to for me at least payquicker and it gets deposited in my nicehash account sooner than I expected.
hopefully when they let up pick which coin to mine on our own it may help somewhat, and any of you who want to move smaller volume will probably benefit when they add the functionality to withdraw other coin/usd.
anyways when their autopilot system works it works great but when it doesn't it's just "okay" for lack of a better word...

Contact: they have a contact us part on their webpage and they also have a reddit page which I was made aware of from contacting them https://www.reddit.com/HoneyMine
Careers: If anyone is interested in working for them the job listings at the time of this typing were for Senior Java Developer(s) and Customer Service Representative(s) the email listed is [[email protected]](mailto:[email protected]). id suggest you check their site for the requirements I just added this part to the review as a courtesy if anyone's interested its not meant to be a focus of it. But I know we have some really talented people on reddit who care about the crypto world passionately so id rather give honyminer a chance to have some of those sort on their team since it might help improve the software faster for the end users.. if that makes sense.
_________________________________________________________
UPDATE: If a question reminds me I left out something I think should have mentioned Ill try to add it here so ppl don't have to scroll all over the place.. I don't write many reviews (for anything) so I don't know if this one was any good or not but I hope it was okay.. and I'm still a new reddit user relatively. I just wanted to make this review mainly because there is next to no information on honyminer when I looked for it and maybe it can help anyone whos interested in it.
browolf2 asked Is it basically like nicehash then? :
A: In a way, its like nice hash that its cloud based, but you get paid not just when your pool completes an order. there are no "buyers" only "sellers" if you look at it that way...I hope I'm wording this the right way.. It's just straight up mining and they take their fee but compared to nicehash the fees for "mining" are different
karl0525 asked: do you know if we can contact the honeyminer dev team and see if they will communicate here on Reddit. Might give them some good ideas what us miners are looking for? Worth a try maybe? Thanks:
A: I submitted a question to their "contact us" part of their webpage and I got a reply from them, this is the message I received below:
Thank you for writing in and for your interest in Honeyminer. We always welcome feedback and suggestions from our users. We are currently planning on expanding our online and social media presence.

The Great NiceHash Profit Explanation - for Sellers (the guys with the GPUs & CPUs)

Let's make a couple of things crystal clear about what you are not doing here:
But hey, I'm running MINING software!
What the hell am I doing then?!?
Who makes Profit, and how?
How is it possible everyone is making a profit?
Why do profits skyrocket, and will it last (and will this happen again)?
But my profits are decreasing all the time >:[
But why?!? I’m supposed to make lotsa money out of this!!!
But WHY!!!
  1. Interest hype -> Influx of Fiat money -> Coins quotes skyrocket -> Influx of miners -> Difficulty skyrockets -> Most of the price uptrend is choked within weeks, since it’s now harder to mine new blocks.
  2. Interest hype drains out -> Fiat money influx declines -> Coins quotes halt or even fall -> Miners still hold on to their dream -> Difficulty stays up high, even rises -> Earnings decrease, maybe even sharply, as it's still harder to mine new blocks, that may be even paid less.
So, how to judge what’s going on with my profits?
Simple breakdown of the relationship of BTC payouts by NiceHash, BTC/ALT Coins rates, and Fiat value:
BTC quote | ALTs quotes | BTC payout | Fiat value ----------------------------------------------------- UP | UP | stable*) | UP stable | UP | UP | UP UP | stable | DOWN | stable*) stable | stable | stable | stable DOWN | stable | UP | stable*) stable | DOWN | DOWN | DOWN DOWN | DOWN | stable*) | DOWN 
Some rather obvious remarks:
More help:
Disclaimer: I'm a user - Seller like you - not in any way associated with NiceHash; this is my personal view & conclusion about some more or less obvious basics in Crypto mining and particularly using NiceHash.
Comments & critics welcome...

Why is it so hard to mine for bitcoin?

Why is it so hard to mine for bitcoin?
Bitcoin mining has become more competitive than ever.
Bitcoin mining difficulty – the measure of how hard it is to earn mining rewards in the world’s largest cryptocurrency by market cap – has reached a new record high above 7.93 trillion. That’s a seven percent jump from the 7.45 trillion record set during the recent two-week adjustment cycle, which was the highest since October 2018.
Bitcoin is designed to adjust its mining difficulty every 2,016 blocks (approximately 14 days), based on the amount of computing power deployed to the network. This is done to ensure the block production interval at the next period will remain constant at around every 10 minutes. When there are fewer machines racing to solve math problems to earn the next payout of newly created bitcoin, difficulty falls; when there are more computers in the game, it rises.

https://preview.redd.it/s7grcdbkzdn31.png?width=728&format=png&auto=webp&s=4fc30767e70d67539747186fdd5a7d01511c4cbd
Data from Bitcoin Block Explorer - BTCNEWZ.com
Right now the machines are humming furiously. Bitcoin miners across the world have been performing calculations at an average 56.77 quintillion hashes per second (EH/s) over the last 14 days to compete for mining rewards on the world’s first blockchain, according to data from mining pool.
Data further indicates the average bitcoin mining hash rate in the last 24-hour and three-day periods were 59.58 EH/s and 59.70 EH/s, respectively, even higher than the average 56.77 EH/s from May 15 to June 27, or any 14-day data in the network’s history.
Similarly, data from blockchain also shows the aggregate of bitcoin computing power was around 66 EH/s as of June 22, surpassing last year’s record high of 61.86 EH/s tracked by the site, and has more than doubled since December 2018 when the hash rate dropped to as low as 31 EH/s amid bitcoin’s price fall.
Assuming all such additional computing power has come from more widely used equipment such as the AntMiner S9, which performs calculations at an average rate of 14 tera hashes per second (TH/s), that suggests more than 2 million units of mining equipment may have been switched on over the past several months. (1 EH/s equals to 1 million TH/s)

https://preview.redd.it/b681p3plzdn31.png?width=1440&format=png&auto=webp&s=49efa21d8460553aceb87b64a106170b30a4c76a
The increase in capacity is also in line with bitcoin’s price jump over the first half of 2019, which caused the price of second-hand mining equipment to double in China, and also juiced demand for new machines.
Further estimates the bitcoin mining difficulty will jump by another seven percent at the beginning of the next adjustment cycle, which would be the first time for bitcoin mining difficulty to cross the eight trillion threshold.
Delayed plugging in
Such computing interest comes at a time when mining farms in China, especially in the country’s mountainous southwest, have been gradually plugging in equipment as the rainy summer approaches.
According to a report published by blockchain research firm Coinshare, as of earlier this month, 50 percent of the global bitcoin computing power was located in China’s Sichuan province.
However, it’s important to note that this year, the arrival of the rainy season in China’s southwest has been delayed by nearly a month compared to previous years. As a result, some local mining farms were only running less than half of their total capacity in the past month.
Xun Zheng, CEO of mining farm operator Hashage based in Chengdu that owns several facilities across China’s southwestern provinces, said there had been no rain in the area for over 20 days since early May, which was “unusual.”
“In the past years, it usually starts raining continuously throughout May so [hydropower plants] normally will have enough water resources by early June,” he said.
As a result, in early June his firm was only operating at 40 percent of capacity; it can host more than 200,000 ASIC miners. But as the rain has arrived gradually over the past two weeks, the proportion has climbed to over 60 percent.
Mining farms in China previously estimated that the total hash rate this year during the peak of the rainy season around August could break the threshold of 70EH/s. That means another 300,000 units of mining machines could be further activated, assuming all are AntMiner S9s or similar models.
Those waiting to be switched on will also include new capital in the sector such as Shanghai-based Fundamental Labs, a blockchain fund that has invested $44 million on top-of-the-line mining equipment, which will be activated in June.

Bitgrin - WHO I AM - introduction for new miners & investors

Bitgrin - WHO I AM - introduction for new miners & investors


https://preview.redd.it/y1nyrhkmoj731.png?width=298&format=png&auto=webp&s=93a62ae0fa7614dcc538e1ace8756a0857fae63f

Bitgrin is a privacy focused cryptocurrency on a protocol level based on MimbleWimble and a fork of GRIN coin.
This is about freedom from censorship and the banker regime.
The technology of Grin meets the economics of Bitcoin, for the worlds first
- private,
- scalable,
- decentralized currency with sound economic model (limited supply)

If you're not clear on what i mean by scalability: Bitcoin has a 240 GB blockchain. Ethereum has a 1TB blockchain. BitGrin will stay below 1GB due to the way old transactions get compressed and pruned
that means i can put a full node on your phone, not just a light wallet but a true full node

Bitgrin mainnet launched the 8th of February 2019

Ticker: XBG
Block time: ~60s
Block reward: 4.5 XBG
Next Halvening: Block 2,102,400
Supply: 21,000,000

Purpose of MimbleWimble is that no one can see your coins or who you sent them too, while still knowing coins are valid.
This is a huge deal in privacy, and we wish that Bitcoin had that from beginning.

But looks like we have a 2nd chance now. Grin failed that in our eyes with horrible economics


==========================================================
TEAM

Our team is anonymous that won't change
We've got a small team who has been in blockchain dev since around 2011 as well as application developers, good at making things user friendly.
This all started because we were working on the Kingfish wallet which was a Grin wallet, and some miner software for Grin. The tech was very cool, but then this emission schedule and the attitude of the core devs made us realize their priorities wrong.
So Kingfish partners joined bitgrin team. Many of us on the original team were not happy with the economic decisions.
We're actually pretty active in Grin Core team chat.

==========================================================
WHAT IS BITGRIN

BitGrin is a store of value, designed to be easy to use
Bitgrin share the same halvening schedule as BTC. Half as many rewards every 4 years. 4.5 coins per block, and then 2.25 after halving, and so on.

So theres really 3 things we bring to the table
  1. We create an economic incentive for folks to hold there coins with halvenings. This means the coin acts more as a store of value.
  2. We create a dev fee so we don't have to be like the Grin team and beg for donations. We'll take modest salaries to keep things running clean
  3. We are building super simple user friendly tools on top of the protocol so that in time the average user can simply pull out a phone and work with XBG coins

BitGrin makes transactions completely private, hiding the amount of coins a user owns, how many have been sent, and to whom they were sent.

Transactions are blinded, which means no-one can prove that coins have been sent at all!

BitGrin is private by design, even the developers don't know who is sending or receiving coins.

But how does it all actually work?
BitGrin is governed by the laws of mathematics, exploiting some very simple properties of addition and multiplication.
Elliptic curve cryptography is at the root of what keeps BitGrin (and Bitcoin) secure. The standard is also used by countless military, banking, and even government operations. Elliptic curve cryptography is a method of utilizing a secure curve to produce privately known numbers These extremely large numbers are nearly impossible to guess, but can be proven to have been generated by someone with knowledge of their private key.

Let me walk you through the process.
First, a user picks a really, really, really large number. Then they multiply it with the starting point on the curve.
The resulting coordinates on the curve are your public key and that really, really big number is your private key!
You can now securely encrypt values utilizing your private key, and publicly share your encrypted messages along with your public key. Other users in the world can *prove* that you must have knowledge of the correct private key, without them knowing what it is.

And this is the bedrock of almost all cryptography. It keeps the whole world secure!
The trick here is that it's pretty easy to get the coordinates of your public key, but it's nearly impossible to discover another user's private key.

A simple analogy for elliptic curve cryptography
Knowing just the public key is like knowing the location of an indestructible box, with the world's most complicated lock. Without the private key, it is impossible to access it's contents.
This is where, for example, Bitcoin's security model ends.
BitGrin, on the other hand, goes a few steps further.
BitGrin hides your even your *public* key. So now no one even knows *where* your indestructible box is.
This means that no one can see how many coins you have, who you are sending coins to, or how many you have received.
All of this is accomplished using just a few additional mathematical tricks.

How Bitcoin transactions work
To further explain, let's first talk about how Bitcoin transactions work.
Lett’s say you, a Bitcoin user, want to send some funds to another user. You would announce publicly to the network your public key, the amount of coins you would like to send, and proof that demonstrates you are indeed the owner of these coins.
You can see the problem here.
If someone goes through the history of the blockchain, they can clearly see who you received the coins from, who you are sending them to, how many were sent, and even how many you have.
You don't really want people knowing all of that information, do you?
Do you share your bank statements with everyone? Of course not.
Now... How can we fix this? How can we make transactions more private?

How BitGrin transactions work
Let's go over a BitGrin transaction...
BitGrin transactions are completely different than Bitcoin transactions, You can think of them as just a blank credit card with no name, just the number, and everyone who knows this number can spend money with it.
What the blockchain holds is just a list of these "cards", while obscuring the amounts in them, and who is in possession of them, or even who had contents in them prior.

Let's say for example I want to send you three BitGrin.
What we need to do now is prove that I own a credit card (or multiple cards) with the total of at least 3 coins.
We also need to create a new card for you. One whose number is only known by you.
First, I send you a message via a secure channel in between our wallets.
"Hey, I want to send you 3 coins. Here's proof I own at least 3. I'll also pay the fee."
You receive the message and you can compute your part of what it takes to make a new card. Then you send me back the proof that you know the new credit card number,
while not revealing the number to me, by using a special type of encryption.
Next, you send me a very very big number you choose to obscure the amount of coins by moving them by this amount on the elliptical curve.
Then, add to it a public key of the credit card number, made with another operation on the graph.
This will prove you own the coins, without either user revealing their private keys.

Finally, I add the number of coins to the very big number you chose.

We can prove the number of coins didn't change because 5-5 is 0. This is validated by the network to prevent coins from being created out of thin air.
And 5 plus the BigNumber, minus 5 plus the BigNumber, is also zero. By adding a hidden big number known only to us, we hide the amount from everyone else.
I combined all these details together into one large commitment, and then submit it to the BitGrin network.
Now the network needs to validate that no new coins were created and that your new card is valid. This is all done with simple mathematics, and is completely secure.
You now received your money! While it may sound like a long process, all of it is done within less than 1 second from the BitGrin wallet.
Want to spice things up? Generate invoices, transact using QR codes or send it by pigeons!

We're not done yet. This is not all that BitGrin improves.
As you may know, BitCoin transactions can take a very long time to be confirmed, and running a Bitcoin node is a very computer-intensive process.
BitGrin on the other hand is both fast, and extremely scalable! The majority of spent transactions get removed, making the blockchain much smaller than traditional blockchains.
This is done by miners in every block, as well as the entire blockchain over time.

Soon, everyone will be able to download the entire blockchain and synchronize it within seconds or minutes, even on a low powered mobile device or a payment terminal at the local checkout.

With further work and research, BitGrin will improve even more, enabling truly private, scalable digital cash to see mass adoption.

==========================================================
TEAM VISION

- Goal to be simple for end user
Crypto is super hard to use, keeping your money private is impossible. Bitgrin solves those problems making the latest scientific breakthroughs in cryptography, usable by everyone, all while being built on robust bitcoin economics. Bitgrin paves the road to mass adoption
there is a lot of confusion about what crypto is for many folks think it is a way to make money by buying new coins and selling as they mature
ignoring the central idea of decentralized money.
Grin folks invented a better BTC, and then proceeded to apply infinite inflation for reasons I can't explain it's decentralized, lightweight, and fast
but you can't just mint 1 new coin every second, thats not sound monetary policy even USD doesnt do anything that extreme
and yet the buying power of USD falls, even with their small inflation schedule and we already know a schedule that seems to work: the Bitcoin schedule
so why not use this in combination with the lightweight blockchain approach of Grin?
Lightning Network doesnt solve BTC problems, because settlement is important, and scale means fees.
Bitgrin solves all of these problems by offering a truly lightweight settlement layer, with no arbitrary P2P layer on top

__________A few words about others MW coins_____________
Grin has Grin economics: infinite coins forever which is kind of insane, Grin could have easily just limited their supply but they refuse to do that.
Our key differentiator is our economically sound emission schedule
Beam and BitGrin are working towards the same kind of thing, or at least our goals are more in line than they are with the Grin team. Our approaches are pretty different, from a technology perspective though. I fully expect all three projects to coexist and hopefully make each other better
Being “non corporate” isn’t necessarily good. To some degree it’s useful to have profits, a core team, etc
But if it’s too corporate (Beam) then your whole organization is susceptible to issues of centralization such as being shut down by the government.
The decentralized nature of the software prevents that to some extent, but nothing beats being driven by a team of anonymous contributors. That is true censorship resistance. It’s a feature, not a bug.
But we don’t need them to lose for us to win, we can win together, I believe a symbiotic mutually beneficial relationship is ideal with the Grin team.

==========================================================
PREMINE

1M coins are put in to height-locked contracts
about 20k released per month, starting next March 2018
so at launch, dev team has 0 coins
10% for 4 yrs, which amounts to 4% of total supply over time
Just a reminder that the dev fee is quite modest. It’s not like we are holding 90% of the supply like ICOs like to do
1mln pub const DEV_FEE_TOTAL: u64 = 1_000_000; // 1M coins to match Satoshi's Bitcoin holdings >> line 58 https://github.com/bitgrin/bitgrin/blob/mastecore/src/consensus.rs
Payouts are staggered over 4 years by the smart contract
I think as far as the community goes, what you would WANT is developers who are paid for success in the same terms they would expect success as buyers/miners.

==========================================================
FUTURE

It took a lot of work to know what to change, and to understand GRIN codebase and then the generatioin of the genesis block wasnt documented
or it was, but it was incorrect.
Getting seed nodes up and running, making the miners work thousands of little details
BitGrin in particular also has rollback protection
Uses block hash checks to make sure the chain stays stable
BitGrin in particular also has rollback protection
Uses block hash checks to make sure the chain stays stable
Also worth noting this is something added by us. Grin doesn’t support block hash checking
It’s not possible to rewrite any meaningful amount of the chain through a 51% attack. Those attacks are quite limited in exclusively abusing double spend
The team is currently working on porting the entire codebase to be web friendly for web wallets, and offline/non-interactive transactions using BitGrin addresses
basically we want to include a tx pool so users dont need to share ips/files, and can simply use disposable "addresses".
A major improvement with we call XBGJS. This will include tools for other devs to make working with BitGrin easier
Adding non-interactive transactions will be a major improvement

==========================================================
MINING
It's compatible with all grin miners
so any grin miner that works with Grin will also work with BitGrin

==========================================================
ASICS
Community will make those decisions when it comes to it, there is time till end of 2019.
We can fork in to a different PoW, as needed.

There are ongoing discussion about it on discord

There is no coin other than bitgrin that has true privacy, scalability, and limited supply it doesn't exist.

I say the more the merrier, this is about growing MW and it’s ecosystem, not about one coin “beating” the other.

But either way competition is healthy, let’s see where this road leads.

Competition is needed for innovation to keep up at a high pace.

Why I just sold 50% of my bitcoins: GHash.IO

tl;dr: GHash.IO shows that the economic incentives behind Bitcoin are probably very flawed, it might take a disaster to get the consensus to fix it, and if that happens I want to make sure I can pay my rent and buy food while we're fixing it.
I made a promise to myself a while back that I'd sell 50% of my bitcoins if a pool hit 50%, and it's happened. I've known for awhile now that the incentives Bitcoin is based on are flawed for many reasons and seeing a 50% pool even with only a few of those reasons mattering is worrying to say the least.
Where do we go from here? We need to do three things:
1) Eliminate pools.
2) Provide a way for miners to solo-mine with low varience and frequent mining payouts even with only small amounts of hashing power.
3) Get rid of ASICs.
Unfortunately #3 is probably impossible - there is no known way to make a PoW algorithm where an ASIC implementation isn't significantly less expensive on a marginal cost basis than an implementation on commodity hardware. Every way people have tried has the perverse effect of increasing the cost to make the first ASIC, which just further centralizes mining. Absent new ideas - ideas that will be from hardware engineers, not programmers - SHA256² is probably the best of many bad choices. (and no, PoS still stands for something other than 'stake')
We are however lucky that we have physics and (maybe) international relations on our side. It will always be cheaper to run a small amount of hashing power than a large amount, at least for some value of 'small' and 'large'. It's the cube-square law, as applied to heat dissipation: a small amount of mining equipment has a much larger surface area compared to a large amount, and requires much less effort per unit hashing power to keep cool. Additionally finding profitable things to do with small amounts of waste heat is easy and distributed all over the planet - heating houses, water tanks, greenhouses, etc. As for international relations, restricting access to chip fabrication facilities is a very touchy subject due to how it can make or break economies, and especially militaries. (but that's a hopeful view)
Solving problem #1 and getting rid of pools is probably possible - Andrew Miller came up with the idea of a non-outsourceable puzzle. While tricky to implement, the basic idea is simple: make it possible for whomever finds the block to steal the reward, even after the fact, in a way that doesn't make it possible to prove any specific miner did it. Adding this protection to Bitcoin requires a hard-fork as described, though perhaps there's a similar idea that can be done as a soft-fork. Block withholding attacks - where miners simply don't submit valid solutions - could also achieve the same goal, although in a far uglier way.
Solving problem #2 and letting miners achieve low varience even with a small amount of hashing power is also possible - p2pool does it already, and tree chains would do it as a side effect. However p2pool is itself just another type of pool, so if non-outsourceable puzzles are implemented they'll need to be compatible. p2pool in its current form is also less then ideal - it does need a lot of bandwidth, and if you have lower latency than average you have a significant unfair advantage. But these are problems that (probably) can be fixed before adding it to the protocol. (this can be done in a soft-fork)
Do I still think Bitcoin will succeed in the long run? Yes, but I'm a lot less sure of it than I used to be. I'm also very skeptical that any of the above will be implemented without a clear failure of the system happening first - there's just too many people, miners, developers, merchants, etc. whose heads are in the sand, or even for that matter, actively making the problem worse. If that failure happens it's quite likely that the Bitcoin price will drop to essentially nothing - not a good way to start a few months of work fixing the problem when my expenses are denominated in Canadian dollars. I hope I'm on the wrong side of history here, but I'm a cautious guy and selling a significant chunk of bitcoins is just playing it safe; I'm not rich.
BTW If you owe me fiat and normally pay me via Bitcoin, for the next 2.5 weeks you can pay me based on the price I sold at, $650 CAD.

such beginner shibe thread wow how to get coin

 how to shibecoin v rich in minutes much instruct so simple any doge can do 

START HERE

UPDATE 1/21/14: I'm not updating this guide anymore. Most of the steps should still work though. See the wiki or check the sidebar for updated instructions.
Before you do anything else, you need to get a wallet. Until there's a secure online wallet, this means you need to download the dogecoin client.
Now open the client you just downloaded. You'll be given a default address automatically, and it should connect to peers and start downloading the dogechain (aka blockchain in formal speak). You'll know because there will be a progress bar at the bottom and at the lower right there should be a signal strength icon (TODO: add screenshots).
If you've waited 2 or 3 minutes and nothing is happening, copy this:
maxconnections=100 addnode=95.85.29.144 addnode=162.243.113.110 addnode=146.185.181.114 addnode=188.165.19.28 addnode=166.78.155.36 addnode=doge.scryptpools.com addnode=doge.netcodepool.org addnode=doge.pool.webxass.de addnode=doge.cryptopool.it addnode=pool.testserverino.de addnode=doge.luckyminers.com addnode=doge.cryptovalley.com addnode=miner.coinedup.comdoge addnode=doge.cryptoculture.net addnode=dogepool.pw addnode=doge.gentoomen.org addnode=doge.cryptominer.net addnode=67.205.20.10 addnode=162.243.113.110 addnode=78.46.57.132 
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
Now restart your qt client and the blockchain should start downloading in about 1-2 minutes.
Once it finished downloading, you're ready to send and receive Dogecoins!

GETTING COINS

Decide how you want to get Dogecoin. Your options are:
I'll go into detail about each of these. I'm currently writing this out. I'll make edits as I add sections. Suggestions are welcome.

MINING

Mining is how new dogecoins are created. If you're new to crypto currencies, read this. To mine (also called "digging"), a computer with a decent GPU (graphics card) is recommended. You can also mine with your CPU, but it's not as efficient.

GPU MINING

These instructions cover only Windows for now. To mine, you'll need to figure out what GPU you have. It'll be either AMD/ATI or Nvidia. The setup for both is approximately the same.

Step One: Choose a pool

There's a list of pools on the wiki. For now it doesn't really matter which one you choose. You can easily switch later.
NOTE: You can mine in two ways. Solo mining is where you mine by yourself. When you find a block you get all the reward. Pool mining is when you team up with other miners to work on the same block together. This makes it more likely that you'll find a block, but you won't get all of it, you'll have to split it up with others according to your share of the work. Pool mining is recommended because it gives you frequent payouts, because you find more blocks. The larger the pool you join, the more frequent the payouts, but the smaller the reward you get.
Over a long period of time the difference between pool and solo mining goes away, but if you solo mine it might be months before you get any coins.

Step two: Set up pool account

The pool you chose should have a getting started page. Read it and follow the instructions. Instructions vary but the general idea is:
When you're done with this, you'll need to know:

Step three: Download mining software

For best performance you'll need the right mining software.
Unzip the download anywhere you want.

Step four: Set up miner

Create a text file in the same folder as your miner application. Inside, put the command you'll be running (remove brackets).
For AMD it's cgminer.exe --scrypt -o stratum+tcp://: -u -p
For Nvidia it's cudaminer.exe -o stratum+tcp://: -O :
Substitute the right stuff in for the placeholders. Then on the next line of the text file type pause. This will let you see any errors that you get. Then save the file with any name you want, as long as the file extension is .bat. For example mine_serverName.bat.

Step five: Launch your miner

Just open the .bat file and a command line window should pop up, letting you know that the miner is starting. Once it starts, it should print out your hash rate.
If you now go to the pool website, the dashboard should start showing your hashrate. At first it'll be lower than what it says in the miner, but that's because the dashboard is taking a 5 minute average. It'll catch up soon enough.
NOTE: A normal hashrate is between 50 Kh/s up to even 1 Mh/s depending on your GPU.

You're now mining Dogecoins

That's it, nothing more to it.

CPU MINING

CPU mining isn't really recommended, because you'll be spending a lot on more on power than you'd make from mining Dogecoin. You could better spend that money on buying Dogecoin by trading. But if you have free electricity and want to try it out, check out this informative forum post.

Trading

Trading has been difficult so far, but Dogecoin just got added to a few new exchanges. If you don't have a giant mining rig, this is probably the best way to get 100k or more dogecoins at the moment. I'll write up a more complete guide, but for now check out these sites:

Faucets

Faucets are sites that give out free coins. Usually a site will give out somewhere between 1 and 100 Dogecoin. Every site has its own time limits, but usually you can only receive coins once every few hours, or in some cases, days. It's a great way to get started. All you do is copy your address from the receive section of your wallet and enter it on some faucet sites. Check out /dogecoinfaucets for more. If you go to each site on there you might end up with a couple hundred Dogecoin!

Begging

This method is pretty straightforward. Post your receiving address, and ask for some coins. Such poor shibe. The only catch is, don't do it here! Please go to /dogecoinbeg.

Tips

At the moment there are two tip bots:
Other redditors can give you Dogecoin by summoning the tip bot, something like this:
+dogetipbot 5 doge
This might happen if you make a good post, or someone just wants to give out some coins. Once you receive a tip you have to accept it in a few days or else it'll get returned. Do this by following the instructions on the message you receive in your inbox. You reply to the bot with "+accept". Commands go in the message body. Once you do that, the bot will create a tipping address for you, and you can use the links in the message you receive to see your info, withdraw coins to your dogecoin-qt wallet, see your history, and a bunch of other stuff.
As a bonus, so_doge_tip has a feature where you can get some Dogecoins to start with in exchange for how much karma you have. To do this, send the message "+redeem DOGE" to so_doge_tip. You'll need to create a tipping account if you don't have one.
If you want to create a tipping account without ever being tipped first, message either of the bots with "+register" and an address will be created for you.
