Unveiling the Ethereum Pectra Upgrade: Major Transformations Await in Q1 2025
Summary:
The Ethereum Prague-Electra (Pectra) upgrade is a combination of two improvements set to transform Ethereum's consensus and execution layers. Scheduled for Q1 2025, Pectra comes after the March 2024 Dencun upgrade and aims to enhance user experiences on the Ethereum platform, streamline Ethereum wallets, and increase staking limits for validators. The upgrade may also include Peer Data Availability Sampling and EVM Object Format to improve smart contract security and developer experiences. Shaped by Ethereum Improvement Proposals (EIPs), Pectra will also consider more EIPs, impacting areas such as validator withdrawals and the deposit window.
Unpacking the Ethereum Prague-Electra (Pectra) Upgrade
The Pectra upgrade set for the Ethereum network is a composite upgrade made up of two noteworthy developments - the Prague and Electra upgrades. The modifications brought by Prague mainly pertain to the execution layer of the network, while Electra creates changes at the consensus layer. Collectively, these enhancements are branded as the "Pectra" upgrade, set to follow after the "Dencun" upgrade, a joint implementation of Deneb and Cancun contributions, which happened in March 2024. Not just another adaptation, the Dencun was an Ethereum hard fork that aimed to bring down transaction costs for layer-2 solutions and significantly elevate Ethereum's scalability.
Scheduled for the first quarter of 2025, Pectra marks a significant stride on Ethereum’s progression chart, with an aim to furnish further features contributing to a better Ethereum user experience (UX). It is anticipated to embrace the Ethereum Improvement Proposal (EIP) 3074, a sequence of code transformations expected to simplify Ethereum wallets, giving users the ability to group their transactions and approve them with a single action. This inclusion in the Pectra upgrade will make average crypto wallets function like smart contracts.
Another anticipated feature of the Pectra upgrade includes EIP-7251 which is set to enhance the staking limit for validators from a current figure of 32 Ether (ETH) to a healthy 2,048 ETH. This upward resizing of the staking limit allows validators to maintain a balance between 32 and 2,048 ETH, creating a variance from the traditional 32 ETH limitation. This move is set to slow down the influx of new validators to the Ethereum network and will result in staking providers dedicating fewer resources to staking and validation procedures.
The upgrade is also likely to involve Peer Data Availability Sampling (PeerDAS) to bolster rollups and the EVM Object Format (EOF) to heighten smart contract security and amplify the developer experience with the Ethereum Virtual Machine (EVM) on layer 1 and layer 2. However, Ethereum developers are debating whether EIP-3074 should be exchanged with EIP-7702, a novel transaction prototype recommended by developers including Ethereum's co-founder, Vitalik Buterin. Their goal is to heighten the compatibility of account abstraction and also look for an upgrade patch for EIP-2935 that deals with the treatment of historical block hashes. Discussions are also ongoing regarding the inclusion of more EIPs in the Pectra upgrade, such as enabling validator withdrawals from smart contracts and eliminating the deposit window.
What's on offer with the Pectra Upgrade?
Pectra provides focused improvements on the consensus layer and execution layer renovations. From June 2024, the Ethereum validators' cap stood at a maximum effective balance of 32 ETH. For staking values bigger than this, staking providers were forced to initiate several validators, each carrying a stake of 32 ETH. The Pectra upgrade seeks to relieve network communication layer pressure of these validators by enlarging the maximum effective balance to 2,048 ETH. This change should reduce inter-validator communications, potentially increasing the efficiency and performance of the network.
Other improvements include the PeerDAS's extension of the “blobs” detailed in EIP-4844, used to optimize transaction data storage and thereby increase block space and reduce transaction fees on Ethereum's layer-2 networks. Additionally, the planned EVM innovations like EOF strive to enhance UX, developer experience (DevEx), and performance on layer 1 and layer 2.
What are EIPs?
These are the crucial elements of Ethereum’s development trajectory and form the core of Ethereum network upgrades. These proposals detail possible features, enhancements, or procedures that may alter the Ethereum blockchain network. The author of an EIP is tasked with achieving consensus amongst the Ethereum development community regarding the proposal and is obligated to document varied opinions.
Roadmap for Ethereum Development
The subsequent upgrade after the March 2024 Dencun upgrade, the Pectra upgrade, is slated for a 2025 release. Ethereum's roadmap following the merge is aligned with Buterin's prescribed five-stage process to boost the smart contract blockchain after Ethereum transitioned to proof-of-stake mechanics in September 2022.
Despite the anticipation surrounding Pectra, the Ethereum developers opted to delay its release from November 2024, to more effectively oversee the upgrade. The upgrade will likely include the awaited “Verkle trees,” a new form of data system enabling Ethereum nodes to hold larger quantities of data.
In a note by Vitalik Buterin, he stated that the Verkle tree feature would allow staking nodes to run almost without the need for hard disk space, and allow syncing to happen at an instantaneous rate, improving UX and light clients facing users. These Verkle trees are under development and will likely be part of the "Osaka" upgrade expected sometime after Pectra’s 2025 release.
