Vice President of Research at Galaxy, Christine Kim, provided a brief synopsis of the most recent Ethereum developers’ call.
Two important dates may be crucial to keep an eye on in the Dencun testing timetable before mainnet activation.
The testnets for Sepolia and Holesky have planned the activation of the Cancun/Deneb upgrade for January 30 and February 7, respectively. Tim Beiko, a core developer for Ethereum, said that an announcement containing client releases should be expected in the upcoming week.

The Shapella update from previous year is followed by the eagerly awaited Dencun upgrade. The Goerli testnet will be the first to see it implemented, followed by Sepolia and Holesky if no significant problems are discovered, according to ETH engineers. The mainnet activation date will be set after Dencun is operating without a hitch on all three testnets.
On the Goerli testnet, the Dencun network upgrade was enabled during the week. A number of modifications were made as part of the update, the most significant of which being the addition of ephemeral data blobs using EIP-4844, or “protodanksharding,” which will assist reduce L2 transaction costs.
Tim Beiko, an Ethereum engineer, describes the circumstances that prevented Goerli from concluding right away following the start of the Dencun update. At the fork, validator participation dropped as predicted but significantly since Goerli had an open validator set.
Furthermore, when Deneb was active, a client problem on the network with Prysm changed the historical root value to 0 rather than transferring over the latest historical root.
After the problem was discovered on Goerli, a solution was created, and a release followed soon after.
The Goerli network ultimately concluded with additional validators going up and one client team upgrading some nodes that had been overlooked.
After achieving this important milestone, Ethereum developers are now moving forward with splitting the testnets of Sepolia and Holesky in preparation for the mainnet launch.
Ethereum’s consensus and execution layers have both undergone modifications as part of the highly anticipated Dencun update. The following are the modifications to the protocol: EIP-4788: Beacon block root in the EVM; EIP-4844: Shard Blob Transactions; EIP-5656: MCOPY (memory copying instruction); EIP-6780: SELFDESTRUCT only in the same transaction; EIP-1153: Transient storage opcodes; Permanently Valid Signed Voluntary Exits (EIP-7044), Max Attestation Inclusion Slot Increase (EIP-7045), Max Epoch Churn Limit Add (EIP-7514), and BLOBBASEFEE opcode (EIP-7516).
