Vitalik Buterin announced a comprehensive roadmap for achieving cross-chain interoperability on Ethereum’s Layer 2 network, focusing on Ethereum’s key improvement proposals and predicting that all rollups will transition to zero-knowledge technology within the next five years.


Summary:


· Vitalik Buterin outlines plan for cross-chain interoperability between Ethereum Layer 2 networks


· The plan includes multiple Ethereum Improvement Proposals (EIPs) aimed at enhancing cross-L2 compatibility


· Major proposals include EIP-3370 for a new address standard, EIP-7683 for cross-L2 communication, and EIP-3668 for off-chain data access


· Vitalik predicts that all rollups will eventually adopt zero-knowledge technology, but this transition may take more than 5 years


· VanEck predicts that the Ethereum L2 scaling network will reach a market cap of $1 trillion within six years


Ethereum co-founder Vitalik Buterin has laid out a comprehensive plan to solve one of the most pressing challenges in the cryptocurrency ecosystem: Ethereum Layer 2. Cross-chain interoperability between Layer 2 (L2) networks.


In a series of posts on social media platform X, Vitalik outlined his vision for a seamless user experience across the “Ethereum universe” and highlighted several key proposals and technical advances that could make that vision a reality.


Vitalik Buterin: I think people will be surprised at how quickly the “cross-L2 interoperability problem” has stopped being a problem and we get a smooth user experience across the entire Ethereum universe, including L1, rollups, validiums, and even sidechains. I see a lot of energy and willingness to make this happen.



Vitalik Buterin: A Tweet to summarize the cross-L2 roadmap:


* 3770 (cross-L2 addresses)

* 7683 (cross-L2 sends via liquidity providers)

* 3668 (L2 light clients)

* Replay account state updates across L2


That’s enough. Next up is phase 2:


* L1sload/static calls

* Keystore Rollups

* Proof aggregation



The roadmap Buterin shared focuses on a set of Ethereum Improvement Proposals (EIPs) designed to enhance cross-L2 compatibility. One of the main proposals is EIP-3370, which introduces a new address standard.


The standard requires wallets and decentralized applications (dApps) to display the addresses of a specific chain using a human-friendly prefix, significantly simplifying the user interface and reducing the likelihood of errors when interacting with different L2 networks.


Another key component of the initiative is EIP-7683, which aims to establish a standard communication protocol for different Ethereum L2 networks. The proposal addresses the current inefficiencies and complexities that users face when trying to trade assets across different chains. By implementing a unified set of rules, EIP-7683 can simplify inter-chain transactions, making it easier and more efficient for users to transfer assets between various L2 solutions.


EIP-3668 is also on the agenda, which proposes a standardized way for Ethereum smart contracts to access off-chain data. Buterin calls it a "layer 2 light client" and explains that it will make it easier and more cost-effective for developers to build data-hungry applications without incurring high on-chain storage costs.


In addition to these proposals, Buterin discussed the concept of "cross-L2 replayable account state updates," which he previously elaborated on in a 2023 blog post. This approach allows L2 networks to receive the latest Layer 1 (L1) state updates while maintaining security and low latency, further enhancing interoperability between different layers of the Ethereum ecosystem.


Looking ahead, Buterin mentioned several updates in Phase 2 to further improve cross-chain L2 compatibility, including keystore Rollups and proof aggregation. He emphasized that the initial "Phase 1" updates are not related to the details of Rollups technology, suggesting wider applicability across different L2 solutions.


Regarding the future of existing zero-knowledge (zk) and Optimistic Rollups, Buterin predicts that all Rollups will eventually transition to zk technology to complete one Ethereum transaction per time slot. However, he estimates that this transition will take more than five years to fully materialize.


The Ethereum co-founder is optimistic about solving the cross-L2 interoperability problem, a view shared by some in the investment community.


Earlier this year, investment manager VanEck predicted that the Ethereum L2 scaling network could reach a market cap of $1 trillion within six years, highlighting the huge potential of Buterin's vision for cross-chain interoperability.


However, Buterin has also recently expressed concerns about overly complex layer 2 scaling solutions, highlighting the potential risks posed by complex L2 networks.


He called for a more balanced approach in the development of the blockchain ecosystem, in line with the general view in the blockchain community that layer 1 networks should prioritize simplicity to minimize the risk of critical bugs and attack vectors.
