The Dencun network upgrade has successfully activated on all testnets. It is now set for deployment on the Ethereum mainnet and will activate on the network at epoch 269568 , occuring on March 13, 2024 at 13:55 UTC.

The upgrade, which follows last year's Shapella upgrade, includes several changes, most notably the introduction of ephemeral data blobs with EIP-4844, also known as "protodanksharding", which will help reduce L2 transaction fees.

The Dencun upgrade combines changes to both Ethereum's consensus and execution layers. The full list of protocol changes can be found in EIP-7569. For reference, they are:

Complete python specifications for changes affecting Ethereum's consensus layer can be found in the deneb folder of the ethereum/consensus-specs repository.

Lastly, Deneb requires changes to the Engine API, used for communication between the consensus and execution layer nodes. These are specified in the cancun.md file of the ethereum/execution-apis repository.
