Pectra: What Will Ethereum’s Next Hard Fork Change and Will Users Feel It?

Ethereum’s upcoming hard fork, Pectra, brings profound changes to the blockchain’s functioning, targeting both the execution and consensus layers. This bifurcated upgrade is designed to enhance performance and security while preparing Ethereum for future architectural overhauls.

Execution Layer Enhancements

**EIP-7702**: Proposed by Vitalik Buterin, this key innovation allows user wallets (External Owned Accounts; EOA) to temporarily access smart contract capabilities introduced by EIP-4844. This will enable gasless payments and multi-operation transactions within a single transaction, significantly improving user experience.
**EIP-7692**: This proposal introduces the first version of the EVM Object Format (EOF), consolidating 11 different EIPs. EOF aims to optimize smart contract deployment and execution, potentially lowering gas costs and enhancing the developer experience.
**EIP-2537**: This technical update enables precompilation of BLS signatures, enhancing the efficiency of operations with the BLS12-381 elliptic curve. It promises a 120-bit security level, 40 bits higher than the current BN24 standard, improving signature aggregation efficiency, reducing gas fees, and boosting validator performance.
**EIP-2935**: This proposal involves storing the last 8192 block hashes in special system storage slots, a step towards a stateless blockchain. This facilitates the creation of a “witness” to provide nodes with necessary hash data, reducing the need for full state storage.
**EIP-7685**: This EIP establishes an enhanced communication channel between the execution and consensus layers, continuing the trend of improved inter-layer cooperation set by the Dencun upgrade.

Consensus Layer Improvements

**EIP-7251**: Validators will be able to deposit between 32 ETH and 2048 ETH into a smart contract, with their chances of being selected as a block creator linked to their stake size. This aims to slow the growth of the validator set driven by liquid staking and restaking trends.
**EIP-7549**: By moving the validator index outside of attestations, this proposal increases consensus client efficiency and storage, allowing up to eight voting slots per block, enhancing network security and resilience.
**EIP-7594**: Introducing the Peer Data Availability Sampling (PeerDAS) protocol, this EIP advances the BLOB technology from EIP-4844, reducing data storage costs for rollups and further lowering transaction costs in Layer 2 networks. This protocol ensures efficient data storage by distributing BLOB content among multiple nodes, enabling full data recovery from stored fragments.

Combined Execution and Consensus Enhancements

**EIP-7002**: This proposal allows the initiation of fund withdrawals from the Ethereum deposit contract using execution layer credentials, solving the dependency issue where stakers rely on validators to withdraw assets, thus eliminating the risk of assets being “held hostage.”
**EIP-6110**: By incorporating validator balances and related operations into the execution layer’s block structure, this EIP reduces the consensus layer’s load. This integration enhances asset security and decreases withdrawal delays from approximately 12 hours to 13 minutes. It simplifies the architecture and maintenance of consensus clients, impacting staking-focused protocols like Lido.
Pectra’s updates are pivotal in Ethereum’s evolution, targeting efficiency, security, and user experience enhancements. As these changes take root, they will pave the way for Ethereum’s ambitious roadmap, ultimately leading to a more robust and user-friendly blockchain environment.
