Summary
The Dencun upgrade, also known as proto-danksharding, is now live on the Goerli testnet. The upgrade aims to increase data availability and reduce transaction fees on Layer 2 of Ethereum. However, the initial deployment of Dencun on Goerli suffered a network split due to a bug in the Prysm Ethereum client. The bug has been identified and fixed, and Dencun is now functioning properly on Goerli. The upgrade will next go live on the Holesky testnet on January 30 before being deployed on the mainnet on February 7. Dencun is expected to significantly reduce fees on Layer 2 and improve scalability by introducing blob data that does not compete with Ethereum transactions for gas usage. This will allow Layer 2 solutions to provide cheaper transactions to their users.
Key Points
1. The Prysm Ethereum client encountered a bug during the Goerli Dencun fork, resulting in a network split.
2. The bug has been identified and a fix is being merged to address the issue.
3. Dencun’s deployment on the Goerli testnet was eventually finalized, allowing L2s to start testing the EIP-4844 upgrade for increased data availability and reduced transaction fees.
