Buterin Unveils Bold Vision to Transform Ethereum Layer-2 Interoperability

Vitalik Buterin, Ethereum’s co-founder, has unveiled his plans to improve cross-chain compatibility among Ethereum layer-2 networks, aiming to enhance the overall Ethereum ecosystem.

In a recent post , Buterin discussed strategies for addressing interoperability challenges between layer-2 solutions, building on his earlier comments about the rapid resolution of these issues. He highlighted several Ethereum Improvement Proposals (EIPs) that are critical to this effort.

One key proposal, EIP-3370, suggests a new address format for wallets and decentralized apps, using readable prefixes for different chains. Another proposal, EIP-7683, focuses on creating a standardized method for layer-2 networks to communicate and trade across various chains, aiming to simplify and improve current processes.

EIP-3668 proposes a standardized approach for Ethereum smart contracts to access off-chain data efficiently, referred to by Buterin as “layer-2 light clients,” which could lower data storage costs on-chain.

Buterin also mentioned future developments like keystore rollups and proof aggregation, which are intended to further enhance layer-2 cross-chain interactions. He expects all rollups to eventually transition to zk-rollups for Ethereum finalization, though this is projected to be several years away.

Earlier this year, VanEck projected that Ethereum’s layer-2 scaling solutions could achieve a $1 trillion market cap in the next six years.
