The OpenChain Project started when David Marr brought people together to talk about improved trust in the supply chain in 2015. The outcome of this action – and his work to lead it as chair from 2016 to 2021 – is dramatically increased trust in the supply chain. As an official outcome of its Q4 2023 Governing Board Meeting, the OpenChain Governing Board hereby thanks David Marr by naming him Chair Emeritus of the OpenChain Project. This is an honorary position that can permanently signal his contribution.
