## Summary
|
|
|
|
The KZG Ceremony is a coordinated public ritual which will provide a cryptographic foundation for Ethereum scaling initiatives. From the specs repo:
|
|
|
|
> 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 role of the sequencer is to act as the common point of interaction for all participants as well as verifying participants' contribution as the ceremony progresses.
|
|
|
|
The ceremony is designed to have the following characteristics:
|
|
|
|
- wide ecosystem participation
|
|
- accessible via browser
|
|
- a meaningful narrative in a simple interface
|
|
- easy to audit transcript
|
|
|
|
The 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.
