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
- browser accessible
- 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.

- eth-KZG-ceremony-alt - Arnaucube
- KZG Ceremony Client - Ignacio Hagopian
- Allows verifying the powers of tau calculation from the currently provided transcript from the verifier
- Apart from using CSRNG for secrets entropy, it supports two opt-in external sources of entropy: the drand network, and an arbitrary URL provided by the user
