Ethereum Pectra Update Starts on Holesky Testnet, Bringing Validator Rewards and Scalability Improvements.
Ethereum Pectra Update Goes Live on Holesky Testnet
Ethereum’s Pectra update will go live today on the Holesky testnet, allowing developers to test the improvements before they are deployed to the Ethereum mainnet.
The Ethereum Foundation announced that Pectra will begin on Holesky at epoch 115,968, followed by its release on the Sepolia testnet at epoch 222,464 on March 5, UTC 07:29. After both testnets successfully update to Pectra, an event epoch will be set for the mainnet.
Pectra introduces features that enhance ETH accounts, support layer-2 scalability, and improve the user experience for validators.
The Pectra fork comes after the Dencun update, which reduced transaction fees for layer-2 networks and improved the economics of ETH rollups. The Dencun hard fork went live on March 13, 2024, marking an important step toward mass adoption.
Pectra is considered a significant advancement in the abstraction of ETH accounts. This update includes EIP-3074, improving Ethereum account abstraction, enabling externally owned accounts (EOAs) to perform batch transactions and receive sponsored gas payments.
Pectra Update Improves ETH Gas Fees and Blob Capacity
The Pectra fork follows the Dencun update, which reduced transaction fees for layer-2 networks and improved Ethereum rollup economics. The Dencun hard fork, released on March 13, 2024, was seen as a crucial step for mass adoption.
Pectra is a major step in Ethereum account abstraction, featuring EIP-3074, which improves Ethereum account abstraction. This update allows externally owned accounts (EOAs) to perform batch transactions and receive sponsored gas payments.
Gas sponsorship allows users to perform transactions through an account without Ether, providing alternative authentication, spending control mechanisms, and other recovery tools.
Additionally, the Pectra update will increase Ethereum’s blob capacity by 50%. Currently, the mainnet supports an average of three blobs per block, but with Pectra, this number will rise to six.
Ethereum’s Pectra Update Brings New Features and Accelerates Roadmap
Blobs are temporary data storage used by layer-2 blockchains to present compressed transaction data and proofs to the mainnet. The integration of blobs into Ethereum makes layer-2 transactions significantly cheaper.
One Ethereum Improvement Proposal (EIP) in Pectra will increase the rewards available to validators. Currently, validators can stake a maximum of 32 ETH, but with Pectra, this maximum balance will increase to 2,048 ETH.
The deployment of Pectra on testnet follows Ethereum developers’ decisions to accelerate the network’s roadmap. In the “All Core Devs” meeting on February 13, ecosystem core developers and leaders supported faster protocol updates.
Nixo Rokish from the Ethereum Foundation’s protocol support team stated that this means more aggressive views with less hesitation about the scope and no further time delays.
