Ethereum’s Merge is framed as one of open source’s biggest coordination feats
The post argues that Ethereum’s move from proof of work to proof of stake may have been one of the largest open-source efforts ever. It required coordination across dozens of teams and many researchers, developers, and volunteers.
The key contrast is organizational: the Merge involved 5 execution clients and 4 consensus clients, each built by independent teams in different languages and all needing to agree perfectly at a single block height. The author contrasts that with SpaceX’s single chain of command, suggesting the Merge had to achieve similar technical precision without centralized control.
