A general-purpose 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 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.

Install dependencies. Most notable inclusion is Zeppelin-Solidity.

npm install

Build, deploy and test via Truffle using the following commands:

npx truffle compile
npx truffle deploy
npx truffle test

When verifying deployed contracts on services like Etherscan, be sure to use truffle-flattener for flattening contracts into single files.

To run the test suite automatically, use a simple:

npm test

This will spin up a local Ganache node in the background. If you'd like to use a persistent node, you can run

npx ganache-cli --gasLimit 6000000

and then test via npx truffle test.

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.
