The post Ethereum’s Dencun Upgrade Nears Mainnet Activation After Successful Testnets appeared first on Coinpedia Fintech News

Ethereum developers are gearing up for the Dencun upgrade, with recent announcements indicating progress on the testnets. Tim Beiko, a core Ethereum developer, shared key dates for the Sepolia and Holesky testnets. 

Dencun Upgrade Overview

The successful activation of the Goerli testnet has marked a significant milestone.

The Dencun upgrade introduces crucial changes, notably the implementation of Shard Blob Transactions with EIP-4844, aimed at reducing Layer 2 transaction fees. Notable protocol changes include enhancements like transient storage opcodes, beacon block root integration in the EVM. 

Several client releases, including Lighthouse, Lodestar, Nimbus, Prysm, and Teku, support Dencun on both Sepolia and Holesky testnets. Ethereum users and stakers are advised to update their nodes to ensure compatibility.

Sepiola and Mainnet Schedule

As per the announcement, Dencun will activate the Sepolia testnet on January 30 and the Holesky testnet on February 7. Ethereum developers emphasize the importance of node operators updating their systems for a seamless transition.

Assuming there will be smooth operations on both the testnets, Ethereum Dencun is set for activation on the mainnet. The upgrade follows last year’s Shapella release and aligns with Ethereum’s strategy for continuous improvements.

Why the name “Dencun”?

Interestingly, the Ethereum community follows a nomenclature tradition for upgrades, combining star names for consensus layer upgrades and Devcon city names for execution layer upgrades. “Dencun” symbolizes the merger of “Deneb,” a prominent star, and “Cancun,” the chosen location for Devcon 3.

In Conclusion

Ethereum’s Dencun upgrade is set to introduce innovative features and enhance network capabilities. Stakeholders are to stay informed and participate in the upcoming testnet activations.
