What is the Pectra? Understanding the Biggest Upcoming Upgrade for the Ethereum Blockchain

Ethereum is preparing for one of its most significant updates yet: the Pectra upgrade. Expected in early 2025, this upgrade combines two crucial enhancements, Prague and Electra, to boost the network’s efficiency, scalability, and wallet functionality. 

As Ethereum continues to evolve, Pectra aims to address core challenges, such as network congestion and validator management, while streamlining the user experience. In this article, we will explore the Pectra upgrade, the key Ethereum Improvement Proposals (EIPs) involved, and how developers plan to implement it.

What is the Pectra Upgrade?

The Ethereum Pectra upgrade is a major milestone in developing the Ethereum network, expected to go live between late 2024 and early 2025. Pectra is designed to address several key issues, including improving the network’s scalability, security, and overall efficiency. 

It combines two updates: the Prague upgrade, which focuses on the execution layer, and the Electra upgrade, which enhances the consensus layer.

The Pectra upgrade also aims to improve wallet functionality by making the process of accessing, managing, and recovering wallets more user-friendly. 

Imagine accessing your Ethereum wallet as easily as a social media account—this is one of the ambitious goals of the Pectra upgrade. Additionally, the upgrade is expected to tackle the issue of validator entries, which are growing at a rapid pace and could potentially overwhelm the network if left unchecked.

Key Ethereum Improvement Proposals (EIPs) in the Pectra Upgrade

At the heart of the Pectra upgrade are several Ethereum Improvement Proposals (EIPs) designed to enhance different aspects of the network. Some of the key EIPs involved include:

1. EIP-3074

One of the most significant changes in the Pectra upgrade, EIP-3074, focuses on improving the user experience with externally owned accounts (EOAs). It introduces account abstraction, allowing traditional wallets like MetaMask to function more like smart contracts. 

This will streamline transaction processes, enabling users to bundle transactions and sign only once, saving time and reducing gas fees. Additionally, it introduces a social recovery mechanism, where users can recover access to their wallets through trusted parties in case they lose their private keys.

2. EIP-7702

This is an advanced version of EIP-3074 proposed by Ethereum co-founder Vitalik Buterin. It builds upon EIP-3074 by making EOAs more compatible with ERC-4337 (account abstraction). Essentially, EIP-7702 allows EOAs to temporarily operate as smart contracts during transactions, making the process more secure and flexible.

3. EIP-7251 

As the number of Ethereum validators has grown, reaching over one million by early 2024, managing this increase has become crucial for the network’s scalability. EIP-7251 aims to address this by raising the maximum effective balance (MaxEB) for validators from 32 ETH to 2048 ETH. This change would consolidate validators and reduce the strain on the network, helping to maintain Ethereum’s security and stability.

Developers Eye a February 2025 Launch with a Split Strategy

During a recent Ethereum developer meeting in September 2024, developers discussed the possibility of splitting the Pectra upgrade into two phases according to the meeting that was done through Zoom. 

This decision would allow the first part of the upgrade to be rolled out as early as February 2025. The split aims to deliver essential improvements faster, reducing risks and ensuring a smoother transition.

There is a consensus that if the upgrade is split, delivering the first phase by February is a realistic target. However, there is concern that if the second half of the upgrade is delayed until June 2025, it could be seen as a failure. 

Splitting the upgrade would allow Ethereum to release the less complex components first, minimising risks and giving developers more time to work on the more intricate elements.

The Prague upgrade (execution layer) and the Electra upgrade (consensus layer) are expected to be split between these two phases. Prague will likely be prioritised in the first phase, focusing on improving transaction processes and wallet functionality, while Electra, which enhances consensus and validator management, could follow later in 2025.

While there is excitement around the Pectra upgrade, Ethereum developers and researchers have noted the complexity of the upgrade. A split may help mitigate risks, but it also comes with the challenge of ensuring both phases are delivered efficiently and on time.

Conclusion

The Ethereum Pectra upgrade is set to be one of the most significant updates in Ethereum’s history, introducing improvements that will enhance scalability, wallet functionality, and validator management. 

With key EIPs like EIP-3074, EIP-7702, and EIP-7251 driving these changes, the upgrade promises to make Ethereum more user-friendly, efficient, and scalable.

While the possibility of splitting the upgrade into two phases exists, with the first phase targeted for February 2025, developers must maintain momentum to ensure both parts are delivered within the expected timeline. 

The success of this upgrade will further solidify Ethereum’s position as a leading blockchain platform, driving innovation and adoption in the decentralised space.
