Ethereum client developers confirmed on Thursday that the long-awaited Dencun upgrade will not be implemented until the end of 2023.

Last month, when the new Holešky testnet successfully launched after the scheduled time, it was widely believed that completing the upgrade before the December holidays was unlikely.

When the optimistic scenario was presented during today’s all-core developer call, anonymous Prysm developer Potuz commented, “We won’t be forking the mainnet in 2023.”

He pointed out that in the past few months, the 10 developer networks (devnets) that have launched test upgrades so far have encountered consistent consensus issues and added, “No progress has gone smoothly.”

Ethereum clients are mainly divided into two camps, the execution layer and the consensus layer, and this difference is reflected in the names of the upgrades – the consensus team uses the names of cities where Ethereum’s main conference Devcon is held (such as Cancun), while the execution client developers choose star names (such as Deneb) – hence “Dencun”.

In contrast to the consensus team, the execution layer client team reported that things are going well for the upcoming testnet.

“We are in a very good position, a lot of things are on the Master now,” said Geth developer Lightclient, referring to the abbreviation for the digital workspace of the Go Ethereum project, where code, files, and revision history are stored.

Devnet 10 launched this week with plans to transition execution clients to larger-scale testing on the Goerli testnet. However, Prysm’s Potuz disagreed with this idea.

“I definitely don’t want to do a full client fork on Goerli,” he said. Regarding Prysm, he added, “I see Prysm still going through significant, deep changes,” with Prysm currently holding a 45% share of the consensus layer clients.

A smaller development network, Devnet 11, was planned, but now it appears that the plan to move to the test network will be postponed until after Ethereum’s Devconnect developer conference, which will take place in Istanbul in mid-November.

Celebrating the KZG Ceremony

The Dencun upgrade requires some complex cryptography to ensure the key security features for Ethereum’s scalability improvements (i.e. Proto-Danksharding).

The KZG ceremony involves multiple participants, each writing a secret and performing a computation that is mixed with the previous contributions. This process generates a “structured reference string” (SRS), which is crucial for the cryptographic scheme proposed by KZG and is an important part of Proto-Danksharding.

The final result of this series of contributions is then incorporated into the upgrade. As long as there is at least one honest participant in the ceremony, the entire setup remains secure. After months of collection, a total of 141,416 contributions were made, ensuring the security of the ceremony.

The Ethereum Foundation’s coordination ceremony invites participants to verify their contributions by visiting ceremony.ethereum.org.

There, individuals can enter their wallet address and receive a commemorative POAP NFT.
