We’ve been working with and contributing one way or another to Quorum since it was made public back in November 2016. Regardless of your views of JP Morgan, having one of the worlds largest financial firms putting their weight behind Ethereum blockchain technology and creating Quorum, was always a significant statement, and it helped further cement our view on the potential of Ethereum in enterprise.
Quorum itself is made up of two parts — the Quorum client which is a fork of Geth, and a secure enclave which is written in Haskell. In order to bring Constellation in line with the Geth and Quorum clients, and tap into the significant Golang community, we decided to rewrite it from scratch in Go, creatingCrux.
Crux is a drop in replacement for Constellation in Quorum blockchains. It supports the same configuration arguments as Constellation to ensure a straight forwards migration.
We’ve got some great enhancements planned for Crux in the future, and we’re really keen to grow a strong community around it going forwards. To make it as straight forwards as possible to get up and running with it, we’ve got a version of the Quorum 7 nodes example that uses Cruxavailable on GitHub.
Otherwise, you can head to therepoand dig around the code.
