Ethereum’s development community has put forward a fresh Ethereum Improvement Proposal, known as EIP-7732, with the objective of revamping the block validation mechanism to accelerate the network’s operations. This proposal delineates a substantial overhaul in block validation, enhancing the blockchain’s security and throughput by bifurcating the process into two distinct phases: consensus and execution.
EIP-7732 emerges as a response to the escalating need for heightened efficiency within the Ethereum blockchain, aligning with the vision of Ethereum’s co-founder, Vitalik Buterin, for expedited transaction confirmation durations.

At the heart of EIP-7732 lies the Enshrined Proposer-Builder Separation (EPBS), a novel framework that segregates the block generation process into two roles: the consensus proposer and the execution proposer. The consensus proposer is tasked with selecting an execution proposer, who is then entrusted with the commitment to construct a valid block replete with critical data, such as transaction payments or block hashes, for the consensus proposer.
A collective of validators, termed the Payload Timeliness Committee (PTC), is charged with the responsibility of ensuring that the execution proposer delivers the pledged block punctually.

Significance of the Initiative
The primary goal of EIP-7732 is to alleviate the computational demands placed on validators by decoupling the consensus and execution layers, thereby augmenting the network’s efficiency and velocity. Currently, Ethereum’s blockchain necessitates that validators concurrently undertake both consensus and execution duties within a constrained timeframe, a requirement that could engender potential bottlenecks and lags.
The EPBS framework is designed to permit validators to concentrate on immediate consensus validation while deferring the execution validation to a subsequent juncture, all without sacrificing the network’s operational efficacy and security. Additionally, the proposed framework advocates for a direct, trustless transaction between builders and proposers, ensuring remuneration and the integration of legitimate blocks, thereby obviating the necessity for intermediary services.

Vitalik Buterin, in a June 30 post, emphasized, “A paramount attribute of an optimal blockchain user experience is the rapidity of transaction confirmations.” The implementation of EIP-1559 has revamped transaction fees and, following the Merge, has reduced Ethereum transaction confirmation times to a range of 5-20 seconds.
While these durations are on par with those of credit card transactions, certain applications demand even quicker transaction speeds—a stark contrast to the existing 12-second interval of the Gasper consensus protocol. With the ongoing deliberations on EIP-7732 and the anticipation of its proposed enhancements, the prospect of accelerated transaction speeds looms on the horizon, albeit at the expense of another hard fork entailing backward-incompatible modifications.
