1## Summary
 2
 3The KZG Ceremony is a coordinated public ritual which will provide a cryptographic foundation for Ethereum scaling initiatives. From the specs repo:
 4
 5> The ceremony takes place between participants and the sequencer. Participants are the entities that contribute their secret randomness to the final output 𝜏 s. The roll of the sequencer it to act as the common point of interaction for all participants as well as verifying participants' contribution as the ceremony progresses.
 6
 7The ceremony is designed to have the following characteristics:
 8
 9- wide ecosystem participation
10- accessible via browser
11- a meaningful narrative in a simple interface
12- easy to audit transcript
13
14The best place to follow along is the KZG Ceremony channel in the Ethereum R&D Discord or the bridged telegram channel - DM one of the contributors to be added to either.
