RESPONSIBILITIES
You will be involved at all stages of the development lifecycle for the Autonity protocol and its blockchain node client (a fork of go-ethereum). These include: - Implementing new protocol features in Go and Solidity - Developing new distributed systems tests and frameworks - Contributing to protocol and design specifications - Working with members of the community to resolve issues - Your work will ensure that Autonity client is correct, reliable, performant, and secure.
