go-nitro

Implementation of the Nitro State Channels Framework in Golang and Solidity.

go-nitro is an implementation of a node in a nitro state channel network. It is software that:

• manages a secret "channel" key
• crafts blockchain transactions (to allow the user to join and exit the network)
• crafts, signs, and sends state channel updates to counterparties in the network
• listens to blockchain events
• listens for counterparty messages
• stores important data to allow for recovery from counterparty inactivity / malice
• understands how to perform these functions safely without risking any funds

Usage

⚠️ Go-nitro is pre-production software ⚠️

Go-nitro can be consumed either as library code or started in an independent process and interfaced with remote procedure calls (recommended).

On-chain code

The on-chain component of Nitro (i.e. the solidity contracts) are housed in the nitro-protocol directory. This directory contains an yarn workspace with a hardhat / typechain / jest toolchain.
