Optimism To Launch ZKPs To Boost Cross-Chain Communication

Key Points:

• Optimism is adding zero-knowledge proofs (ZKPs) to enable secure and efficient cross-chain communication between its Layer 2 solution and Ethereum.
• The ZKPs will be provided by O(1) Labs and RISC Zero, enhancing security and reducing latency in the network.
• Optimism aims to improve its ecosystem’s performance and compatibility with existing systems, paving the way for more accessible development using Solidity and EVM.

The Ethereum Layer 2 scaling solution, Optimism, is making strides in improving cross-chain communication with the integration of zero-knowledge proofs (ZKPs). The initiative aims to enable secure and efficient communication between layers and directly between OP chains, enhancing privacy and security in blockchain transactions.

Optimism recently shared that they will be moving forward with proposals from O(1) Labs and RISC Zero, both offering innovative solutions to bring ZKPs to the platform. ZKPs are cryptographic concepts that allow one party to prove the truth of a statement to another party without revealing any additional information. This implementation will revamp Optimism’s tech stack, ensuring faster and more secure transactions.

RISC Zero’s proposal seeks to upgrade Optimism’s existing fault protocol, using ZKPs to validate state changes on the platform. Users can prove the correctness of state changes with ZKPs, while also challenging any incorrect state changes with supporting proofs.

On the other hand, O(1) Labs, known for incubating the Mina Protocol, is proposing a new fault-proof solution using Kimchi, a ZK-proof system used in Mina. This solution allows efficient proof of correct transaction execution, which is then used to update the Ethereum network’s state via smart contracts, enhancing performance, security, and compatibility.

The incorporation of ZKPs will enhance Optimism’s cross-chain communication capabilities by bolstering security, decreasing latency, and making the platform more affordable and efficient. The Optimism Foundation is actively working with O(1) Labs and RISC Zero to finalize the project and set detailed expectations.

The addition of ZKPs to Optimism’s layer 2 solution signifies a major milestone in the platform’s development, providing a more versatile and secure environment for users and developers alike. The move aligns with the growing trend of improving compatibility between various blockchain ecosystems and paves the way for more efficient and accessible blockchain interactions.

The project’s name has been changed to OP Mainnet to reflect the goal of creating a “superchain” network of several Layer 2 blockchains.
