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.
