On February 28, 2024, Coinbase Cloud announced that they were adding support for additional Ethereum execution clients, with Nethermind, and eventually other clients like Erigon. Coinbase has repeatedly shown a deep commitment to the success of the Ethereum network and we look forward to a long and fruitful relationship. This commitment builds on Coinbase's previous shift in conensus client diversity and is a big milestone toward ensuring the predictable operation of the Ethereum chain for decades to come.

The address which minted this POAP participated in the KZG Summoning Ceremony: a publicly coordinated ritual to produce a random output. This output will be used in Proto-Danksharding, aka EIP 4844: an Ethereum scaling mechanism which will hopefully enable lower Layer 2 fees and greater global accessibility. EIP-4844 is expected to go live with the Dencun network upgrade in the near future. As of the time of writing, this ceremony was the largest setup of this kind when considering the number of contributions.
