Ethereum Dencun upgrade navigates testnet seamlessly, EIP-4844 could see mainnet release in March

  • Ethereum developers tested the Dencun upgrade on Sepolia testnet without any hiccups. 
  • The next step to EIP-4844’s mainnet launch is the Holesky testnet release. 
  • Dencun’s smooth testnet releases could bring the next major upgrade to Ethereum in March 2024. 

Ethereum network’s next major upgrade after its Merge is Dencun. The upgrade will implement several Ethereum Improvement Proposals, the most notable of which is EIP-4844. The improvement proposal, better known as protodanksharding, will reduce transaction costs for Layer 2 chains.

Ethereum Dencun upgrade successfully clears Sepolia testnet

The Dencun upgrade observed a successful implementation with no major issues, on the Sepolia testnet. Ethereum core developers Paritosh J and Tim Beiko shared the status update in recent tweets on X (formerly Twitter).


Ethereum holders and crypto market participants consider this upgrade key to the ETH ecosystem since it will bring major changes to the network, for the first time since the shift of the consensus mechanism from Proof-of-Work to Proof-of-Stake in the Merge. The upgrade will introduce blobs, data units that are attached to Ethereum network’s existing blocks. These blobs reduce the specific storage required by Layer 2 chains, reduce the operation costs and transaction costs. 

EIP-4844 is now closer to its mainnet release and the only step left in the process of its rollout on the Ethereum chain is the Holesky testnet. A successful completion of its release on Holesky will pave the way for EIP-4844 and Dencun’s arrival on Ethereum by March.

Christine Kim, Head of Research at Galaxy Digital has put the odds of Ethereum’s Dencun release on the mainnet at 70%.
