The Urbit PKI on the Ethereum blockchain.
This is a work in progress nearing completion. Feel free to poke around and open issues or ask questions. The Urbit fora is also a good place for open-ended discussion related to this repo.
This is just a quick summary of the different contracts and their purposes. For more detailed descriptions, check out the contracts themselves.
- Ships: contains all on-chain state for Urbit ships. Most notably, ownership and public keys. Can't be modified directly, you must use the Constitution.
- Constitution: is used as an interface for interacting with your ships on-chain. Allows you to configure keys, transfer ownership, etc.
- Polls: registers votes by the senate on proposals. These can be either static documents or Constitution upgrades.
- Delegated Sending: allows stars to let their planets send brand new planets to their friends and family.
- Linear Star Release: facilitates the release of blocks of stars to their owners over a period of time.
- Conditional Star Release: facilitates the release of blocks of stars to their owners based on milestones.
- Planet Sale: gives an example of a way in which stars could sell planets on-chain.
- Pool: gives an example of a way in which stars could be temporarily tokenized.
Install dependencies. Most notable inclusion is Zeppelin-Solidity.
npm install
Build, deploy and test using Truffle.
npm install -g truffle
Use any of the following commands.
truffle compile
truffle deploy
truffle test
When verifying deployed contracts on services like Etherscan, be sure to use truffle-flattener for flattening contracts into single files.
To successfully run the tests, make sure Ganache (or any other RPC enabled node) is running locally.
ganache-cli --gasLimit 6000000
The Planet Sale's test relating to withdrawing ETH from the contract are known to be finicky during tests, and may not always complete successfully.
This version of the contracts has been deployed to the Ethereum Ropsten testnet. Their addresses are:
