What is the Ethereum Prague-Electra (Pectra) Upgrade?

Key Takeaways:

• The Pectra upgrade combines two major updates, Prague and Electra, to enhance Ethereum’s scalability, efficiency, and usability.

• It introduces features like Account Abstraction, Verkle Trees, and PeerDAS, to optimize transaction costs and improve network performance.

• The rollout is divided into two phases: foundational improvements in 2025 and advanced technical upgrades in 2026.

Ethereum’s Prague-Electra (Pectra) upgrade is one of the most anticipated developments in blockchain technology. Combining the Prague and Electra updates, this hard fork aims to address long-standing challenges on the Ethereum network, such as high transaction fees, scalability bottlenecks, and staking inefficiencies. With its two-phase rollout scheduled for 2025 and 2026, Pectra promises to make Ethereum faster, cheaper, and more user-friendly for developers and everyday users.

Understanding the Pectra Upgrade

The Pectra upgrade marks a significant milestone in Ethereum’s roadmap. Following the Dencun upgrade in 2024, which improved layer-2 scalability and reduced transaction fees, Pectra builds on these advancements by introducing cutting-edge features that enhance both the execution layer (via Prague) and the consensus layer (via Electra). These updates are designed to streamline staking processes, optimize data storage, and expand payment options for gas fees.

Key EIPs in the Pectra Upgrade

The Pectra upgrade introduces 11 EIPs that bring transformative changes to Ethereum. Here’s a breakdown of some of the most impactful proposals:

Execution Layer EIPs:

1. EIP-7251 (increased staking limit): Raises the maximum validator balance from 32 ETH to 2,048 ETH. This allows validators to stake larger amounts more efficiently while still requiring 32 ETH to start. For example, someone with 40 ETH can now stake it all under one validator, instead of splitting it across multiple validators.

2. EIP-7691 (blob data expansion): Doubles the amount of blob data per block from three to six blobs (with a maximum of nine). This reduces transaction fees on layer-2 networks by enabling more data storage per block.

3. EIP-7623 (higher call data costs): Increases gas costs for call data to encourage developers to use blobs for data storage. This shift improves scalability while keeping fees stable for regular users.

4. EIP-7702 (smart accounts): Enables regular wallets to temporarily act as smart contracts during transactions. This supports features like gas fee sponsorships and batch transactions, simplifying user interactions with decentralized applications.

Consensus Layer EIPs:

1. EIP-6110 (faster staking deposits): Speeds up validator activation by processing deposits directly on the execution layer. This reduces waiting times for stakers.

2. EIP-7002 (simplified validator withdrawals): Enables validators to unstake their ETH through a straightforward Ethereum transaction instead of relying on complex processes.

3. EIP-2537 (advanced cryptographic proofs): Introduces precompiled contracts for BLS signatures and zero-knowledge proofs, reducing costs for developers working on secure applications like rollups and cross-chain bridges.

4. EIP-2935 (extended block history): Keeps up to 27 hours of historical block hashes on-chain instead of just 51 minutes, improving reliability for applications that depend on past data.

The Two-Phase Rollout

To ensure a smooth transition, developers have divided the Pectra upgrade into two distinct phases:

Phase One: March 2025

This phase focuses on foundational improvements:

• Enhanced staking mechanisms with an increased cap of 2,048 ETH per validator.

• Expanded blob capacity to reduce fees on layer-2 networks.

• Introduction of Account Abstraction for multi-currency fee payments.

Phase Two: 2026

The second phase will bring advanced technical upgrades:

• Implementation of Verkle Trees for better data storage.

• Deployment of PeerDAS to optimize transaction verification.

• Introduction of EVM Object Format (EOF) to make smart contracts more efficient.

Benefits for Ethereum Users

The Pectra upgrade is designed with both developers and end-users in mind. Here’s how it will improve your experience on Ethereum:

• Lower transaction costs: With expanded blob capacity and third-party sponsorships for gas fees, users may see reduced or even zero transaction costs in some cases.

• Improved wallet features: Social recovery options will help users regain access to lost wallets through trusted contacts. Native multisig wallets will add an extra layer of security by requiring multiple approvals for transactions.

• More flexible payments: Paying gas fees with tokens other than ETH simplifies interactions with decentralized applications (dApps).

• Streamlined smart contracts: Developers will benefit from optimized tools that make deploying smart contracts faster and more efficient.
