Vitalik Buterin Unveils Bold Plan for Seamless Cross-Chain L2 Interoperability

Ethereum co-founder Vitalik Buterin outlines a roadmap to solve cross-chain L2 interoperability, aiming to enhance the Ethereum ecosystem with smoother user experiences.

Vitalik Buterin has shared his vision for achieving seamless cross-chain interoperability between Ethereum layer-2 networks. In an Aug. 6 X post, Buterin discussed the most promising paths to solving cross-layer-2 interoperability issues, suggesting that these problems will soon be a thing of the past.


Ethereum co-founder Vitalik Buterin discusses plans for achieving cross-chain interoperability within the Ethereum ecosystem.
Vitalik Buterin outlines roadmap for seamless cross-chain L2 interoperability.

Key Points:


  • Vitalik Buterin's Vision: Buterin expresses confidence that cross-L2 interoperability issues will soon be resolved, leading to a smoother user experience within the Ethereum ecosystem.


  • Ethereum Improvement Proposals (EIPs):

EIP-3370: Introduces a new address standard with human-readable prefixes for wallets and dApps.


EIP-7683: Proposes a standardized method for different Ethereum L2 networks to communicate and execute trades across chains.


EIP-3668: Outlines a standardized method for Ethereum smart contracts to access off-chain data, termed "layer-2 light clients."


  • Cross-L2-Replayable Account State Updates: Ensures that L2s receive recent L1 state updates while maintaining security and low latency.


  • Future Updates: Phase 2 improvements include keystore rollups and proof aggregation to enhance cross-chain L2 compatibility.


  • Rollup Technology: Buterin predicts all rollups will eventually adopt zk technology, leading to more efficient finalization to Ethereum.


  • Market Impact: Investment manager VanEck predicts Ethereum L2 scaling networks could reach a $1 trillion market cap within six years.



Vitalik Buterin's roadmap for cross-chain L2 interoperability represents a significant step forward for the Ethereum ecosystem. By addressing these issues, Ethereum aims to offer a smoother and more efficient user experience, paving the way for broader adoption and innovation.
