The post Ethereum validators to adopt new roles with EIP-7732 appeared on BitcoinEthereumNews.com.

Ethereum’s validators are set to take on new roles with the introduction of EIP-7732, the Enshrined Proposer-Builder Separation proposal. This proposal fundamentally changes how Ethereum blocks are validated by splitting execution validation from consensus validation both logically and temporally. Validators get overhauled Validators now have new responsibilities, including the option to become builders and the duty to submit payload timeliness attestations. The EIP addresses multiple key issues in the current system. Most beacon block proposers outsource the construction of the execution payload to a third party, known as a builder. Source: Ethereum They request the hash tree root (HTR) of a promised execution payload and submit a SignedBlindedBeaconBlock to a trusted party. This party then replaces the HTR with the full execution payload from the builder before broadcasting. The EIP guarantees fair exchanges between the beacon block proposer and the builder. It ensures that an honest beacon block proposer gets paid by the builder, and an honest builder’s payload becomes the canonical head of the chain. Currently, validators have a short window to perform both consensus and execution state transitions, check blob data availability, and evaluate the new head of the blockchain.

Execution and data availability validation is deferred, allowing validators to perform these tasks in the remaining slot time. Motivation behind EIP-7732 Removing the full execution payload from the consensus block allows for faster network propagation. It reduces the likelihood of reorganization when including blob transactions due to increased timelines for data availability checks. Validators no longer miss attestations, strengthening fork choice properties when builders produce invalid payloads. The EIP also eliminates the need for trusted middleware for block construction…
