-------------------------------------------------------------------------------- 1 | # Contributor Covenant Code of Conduct 2 | 3 | ## Our Pledge 4 | 5 | In the interest of fostering an open and welcoming environment, we as 6 | contributors and maintainers pledge to making participation in our project and 7 | our community a harassment-free experience for everyone, regardless of age, body 8 | size, disability, ethnicity, sex characteristics, gender identity and expression, 9 | level of experience, education, socio-economic status, nationality, personal 10 | appearance, race, religion, or sexual identity and orientation. 11 | 12 | ## Our Standards 13 | 14 | Examples of behavior that contributes to creating a positive environment 15 | include: 16 | 17 | * Using welcoming and inclusive language 18 | * Being respectful of differing viewpoints and experiences 19 | * Gracefully accepting constructive criticism 20 | * Focusing on what is best for the community 21 | * Showing empathy towards other community members 22 | 23 | Examples of unacceptable behavior by participants include: 24 | 25 | * The use of sexualized language or imagery and unwelcome sexual attention or 26 | advances 27 | * Trolling, insulting/derogatory comments, and personal or political attacks 28 | * Public or private harassment 29 | * Publishing others' private information, such as a physical or electronic 30 | address, without explicit permission 31 | * Other conduct which could reasonably be considered inappropriate in a 32 | professional setting 33 | 34 | ## Our Responsibilities 35 | 36 | Project maintainers are responsible for clarifying the standards of acceptable 37 | behavior and are expected to take appropriate and fair corrective action in 38 | response to any instances of unacceptable behavior. 39 | 40 | Project maintainers have the right and responsibility to remove, edit, or 41 | reject comments, commits, code, wiki edits, issues, and other contributions 42 | that are not aligned to this Code of Conduct, or to ban temporarily or 43 | permanently any contributor for other behaviors that they deem inappropriate, 44 | threatening, offensive, or harmful. 45 | 46 | ## Scope 47 | 48 | This Code of Conduct applies both within project spaces and in public spaces 49 | when an individual is representing the project or its community. Examples of 50 | representing a project or community include using an official project e-mail 51 | address, posting via an official social media account, or acting as an appointed 52 | representative at an online or offline event. Representation of a project may be 53 | further defined and clarified by project maintainers. 54 | 55 | ## Enforcement 56 | 57 | Instances of abusive, harassing, or otherwise unacceptable behavior may be 58 | reported by contacting the project team at contact@streamr.com. All 59 | complaints will be reviewed and investigated and will result in a response that 60 | is deemed necessary and appropriate to the circumstances. The project team is 61 | obligated to maintain confidentiality with regard to the reporter of an incident. 62 | Further details of specific enforcement policies may be posted separately. 63 | 64 | Project maintainers who do not follow or enforce the Code of Conduct in good 65 | faith may face temporary or permanent repercussions as determined by other 66 | members of the project's leadership. 67 | 68 | ## Attribution 69 | 70 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, 71 | available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html 72 | 73 | [homepage]: https://www.contributor-covenant.org 74 | 75 | For answers to common questions about this code of conduct, see 76 | https://www.contributor-covenant.org/faq 77 | -------------------------------------------------------------------------------- /CONTRIBUTING.md: -------------------------------------------------------------------------------- 1 | == How to contribute == 2 | 3 | * Check out the repo 4 | * Run the demo using [instructions in the README](README.md) 5 | * If you bump into problems: 6 | * Fix them, and open a pull request :) 7 | * Contact us in [Telegram](https://t.me/streamrdata) 8 | 9 | Thanks, happy hacking! 10 | -------------------------------------------------------------------------------- /contracts/Airdrop.sol: -------------------------------------------------------------------------------- 1 | pragma solidity ^0.5.16; 2 | 3 | import "openzeppelin-solidity/contracts/math/SafeMath.sol"; 4 | import "openzeppelin-solidity/contracts/token/ERC20/IERC20.sol"; 5 | 6 | import "./BalanceVerifier.sol"; 7 | import "./Ownable.sol"; 8 | 9 | /** 10 | * Hypothetical "continuous airdrop" where recipients can withdraw tokens allocated off-chain. 11 | * Simplest root chain contract implementation. 12 | * For purposes of illustrating implementing the BalanceVerifier, and mainly for testing it. 13 | */ 14 | contract Airdrop is BalanceVerifier, Ownable { 15 | using SafeMath for uint256; 16 | 17 | IERC20 public token; 18 | mapping (address => uint) public withdrawn; 19 | 20 | constructor(address tokenAddress) Ownable() public { 21 | token = IERC20(tokenAddress); 22 | } 23 | 24 | /** 25 | * Owner commits the balances 26 | */ 27 | function onCommit(uint, bytes32, string memory) internal { 28 | require(msg.sender == owner, "error_notPermitted"); 29 | } 30 | 31 | /** 32 | * Called from BalanceVerifier.prove, perform payout directly (ignoring re-entrancy problems for simplicity) 33 | */ 34 | function onVerifySuccess(uint, address account, uint balance) internal { 35 | require(withdrawn[account] < balance, "error_oldEarnings"); 36 | uint withdrawable = balance.sub(withdrawn[account]); 37 | withdrawn[account] = balance; 38 | require(token.transfer(account, withdrawable), "error_transfer"); 39 | } 40 | } 41 | -------------------------------------------------------------------------------- /contracts/BalanceVerifier.sol: -------------------------------------------------------------------------------- 1 | pragma solidity ^0.5.16; 2 | 3 | /** 4 | * Abstract contract, requires implementation to specify who can publish commits and what 5 | * happens when a successful proof is presented 6 | * Verifies Merkle-tree inclusion proofs that show that certain address has 7 | * certain earnings balance, according to hash published ("signed") by a 8 | * sidechain operator or similar authority 9 | * 10 | * ABOUT Merkle-tree inclusion proof: Merkle-tree inclusion proof is an algorithm to prove memebership 11 | * in a set using minimal [ie log(N)] inputs.

11 | This is a demonstration of how Monoplasma contracts can be used to implement basic ERC-20 token revenue 12 | sharing. There are three main roles in the system: 13 |

14 | 32 |

33 | The Operator 34 |
35 | Normally the operator publishes commits when the first revenue transaction arrives after 36 | a cooldown period. This cooldown period plus the freeze period is the time it takes for 37 | a member to be able to withdraw tokens after the token transaction where they earned them. The point 38 | of the cooldown period is to not unnecessarily pay for commit transaction if revenue arrives rapidly. 39 |

40 |

41 | All tokens earned during this period are in the hands of the operator (similar to tokens on an 42 | exchange). The member can lose only those tokens in case of total breakdown of the operator. 43 | By pressing the Force Publish button you can ask the operator to send a commit transaction even during 44 | the cooldown period or if no revenue has been added. 45 |
