- Ethereum developers propose the “Beam Chain,” integrating zero-knowledge cryptography into its consensus layer
- Layer-2 leaders zkSync and Polygon support the changes, citing benefits to scaling and cost efficiency
What happened
Last week, at the biennial Devcon gathering in Bangkok, Thailand, developer Justin Drake laid out an ambitious plan to revamp Ethereum’s consensus layer architecture. This plan, targeting a launch in 2029, seeks to reduce transaction costs, improve scalability, and introduce single-slot finality for instant block validation. Teams from leading Layer-2 networks, such as zkSync and Polygon, expressed strong support, emphasizing the changes focus on Ethereum’s consensus layer without affecting their execution layer operations. ZK rollups, which compress transaction data for speed and efficiency, remain central to Ethereum’s roadmap, with the proposal enhancing their function rather than making them obsolete.
That’s the assessment the teams behind zkSync and Polygon, two of the leading layer-2 networks running on top of Ethereum, gave of a recent proposal to overhaul the $400 billion blockchain, dismissing suggestions it would make their auxiliary networks redundant.

What it’s important
The Beam Chain proposal is a pivotal step for Ethereum, reinforcing its position as a blockchain leader by integrating zero-knowledge (ZK) cryptography directly into its consensus layer. This move highlights the platform’s response to competitive pressures from blockchains like Solana and Avalanche, which have gained traction for their speed and cost efficiency. For smaller companies like Matter Labs, the developer of zkSync, the upgrade ensures their Layer-2 solutions remain indispensable by benefiting from lower transaction costs and faster settlements.
The broader implications extend to industries reliant on Ethereum for decentralized finance (DeFi), gaming, and supply chain solutions. The proposed changes will significantly reduce bottlenecks for small developers building on Ethereum, allowing them to scale without incurring prohibitive costs. For instance, startups like Immutable, which leverages Layer-2 technology for gaming NFTs, could see faster adoption of their platforms. By positioning Ethereum as a more robust global settlement layer, the proposal supports ecosystem growth, benefiting developers and users alike.
