⚖️ darknode-sol

Solidity smart contracts used by Ren Darknodes

darknode-sol contains a collection of Ethereum smart contracts utilized by the Ren Darknodes, written in Solidity. Ren bootstraps off Ethereum as a trusted third-party computer to handle Darknode registration and fee payouts.

Ren is powered by the RenVM — the Ren Virtual Machine — in a decentralized network of Darknodes that is distinct from Ethereum. This ensures the performance of the network, and the privacy of data, is not dependent on Ethereum.

Tests

Install the dependencies.

yarn install

Run the ganache-cli or an alternate Ethereum test RPC server on port 8545. The -d flag will use a deterministic mnemonic for reproducibility.

yarn ganache-cli -d

Run the Truffle test suite.

yarn run test

Coverage

Run the Truffle test suite with coverage.

yarn run coverage

Open the coverage file.

open ./coverage/index.html

Deploying

Add a .env, filling in the mnemonic and Infura key:

MNEMONIC_KOVAN="..."
MNEMONIC_MAINNET="..."
INFURA_KEY="..."

Deploy to Kovan:

NETWORK=kovan yarn run deploy

See 1_darknodes.js for additional instructions.

Verifying Contract Code

Add an Etherscan API key to your .env:

ETHERSCAN_KEY="..."

Run the following (replacing the network and contract name):

NETWORK=mainnet yarn run verify Contract1 Contract2
