Mixicles

Warning: This prototype code is meant to elucidate and test ideas in the Mixicle paper. It is not production-ready, and not meant for deployment.

Setup

yarn install

Running the Adapter

yarn start

You can configure the port the adapter runs on by setting MIXICLES_PORT and the key it uses to sign by setting MIXICLES_KEY.

Test vector for roundParams

Here is a test vector for the following (decoded) roundParams:

uint128 roundIndex = 2;
uint256 requiredBalance = 3 ether;
uint256 setupDeadline = 5000000;
uint256 reportDeadline = 6000000;
uint256 dealId = 0xabcdef47abcdef47abcdef47abcdef47abcdef47abcdef47abcdef47abcdef47;
uint256 chainlinkPayment = 11 * LINK;
bytes32 termsCommit = bytes32(0x1122334455667788112233445566778811223344556677881122334455667788);

encoded using solidity ABI encoding (in our case, simple concatenation + padding to 32 bytes + big-endian numbers):

0x000000000000000000000000000000000000000000000000000000000000000200000000000000000000000000000000000000000000000029a2241af62c000000000000000000000000000000000000000000000000000000000000004c4b4000000000000000000000000000000000000000000000000000000000005b8d80abcdef47abcdef47abcdef47abcdef47abcdef47abcdef47abcdef47abcdef4700000000000000000000000000000000000000000000000098a7d9b8314c00001122334455667788112233445566778811223344556677881122334455667788

the keccak256 hash of the encoded roundParams is signed by the external adapter. it is: 0xe587d3d48510f67b15a72b9566d6c1e5eef15be530ad0d9c2f52473e8c97d9f7
