The KZG event was the largest multi-party computation of its kind (in terms of number of participants). We have built a secure cryptographic foundation through open and accessible processes. EIP-4844.

As the Dencun upgrade approaches, this post will be a comprehensive record of the results and people who brought the 2023 celebrations to life.
Results and Methods
The awards ceremony was held for: 208 days: at January 13, 2023 13:13 UTC to August 8, 2023 23:08 UTC
141,416 contributions At the time of publication, it was the largest setting of its kind.
Contributors had to log in through Github or authenticate using an Ethereum address to prevent spam.
- 132,021 (93.36%) use Ethereum to log in
- 9,395 (6.64%) use Github
For additional spam protection, Ethereum addresses were required to send a certain number of transactions (also known as a “nonce”) before the event started at block 16,394,155 at 2023/01/13 00:00 UTC. These requirements have been modified throughout to meet the needs of the time.
- January 13 – March 13: nonce 3
- March 13 – April 1: No new logins, but lobbies are allowed to be deleted. Anyone who was already logged in could complete their contribution.
- April 1-16: Public donations are closed to accommodate special donations.
- April 16-25: 128
- April 25 – May 8: 64
- May 8-25: 32
- May 25 – June 27: 16
- June 27 – August 23: 8
To prevent bots or scripts from interfering with honest contributors, a process has been established to blacklist accounts with excessive logins/pings. The blacklist has been removed to reset honest accounts that were accidentally added to the list. four times Throughout the contribution period.
Checking report card

The report card is available on GitHub. ethereum/kzg-ceremony repository or through IPFS under CID QmZ5zgyg1i7ixhDjbUM2fmVpES1s9NQfYBM2twgrTSahdy.
There are several ways to check your transcript. You can explore and check it out here. event.ethereum.orgor Dedicated verification script Written in rust.

There was a commemorative event POAP NFTs Claims can be made by contributors who log in with their Ethereum address. The design of POAP matches that of the original hosted interface and includes a hash of the record in the border (8ed…848). To date, participants have claimed over 76,000 NFTs. Anyone who saw the report card printout could tweet it as social proof of success. See recent confirmed tweets. here.
special donation
April 1 to 16, 2023 was a special donation period for the KZG Memorial. This allowed participants to contribute in ways that would not have been possible during an open giving period.
Although only one honest participant is needed to provide a secure result, special contributions provide additional guarantees beyond standard entropy contributions.
- Computing entropy in an isolated environment (e.g., wiping and physically destroying hardware in an airtight system) means that there is no possibility for a malicious entity to extract the entropy at any point.
- It is unlikely that all of the detailed documentation attached to the actual reputation (link navigation below) has been stolen or forged by a malicious mediation entity. The records are available for future observers to explore.
- Risks related to different hardware and software limitations
- Differentiated entropy generation (e.g., explosion measurements) prevents Ceremony output from being corrupted by some errors in general entropy generation (e.g., hosting interface).
- Contributions made by many people are more difficult to fake than contributions made by just one person.

thanks
Given that security was of utmost importance for this project, we conducted two audits of different components.
client implementation
There were many independent implementations that event attendees could run locally with a variety of features.
