Uniswap Labs, the development company of the decentralized cryptocurrency exchange Uniswap, announced last weekend that its Ethereum layer 2 network Unichain is expected to launch a public mainnet in early 2025 and plans to integrate permissionless proof of failure on the first day of mainnet launch.

Unichain is an Optimal Rollup built on top of the OP Stack, aimed at addressing the challenges faced by decentralized finance (DeFi) and achieving seamless multi chain exchanges by becoming part of the Optimism Superchain and ERC-7683 initiatives.

Unichain Currently running on Ethereum's Sepolia testnet, it has processed over 50 million test transactions since October and deployed over 4 million test contracts. According to Uniswap, all critical services of Unichain Sepolia have maintained over 99% of their normal operating time.

Starting from January 6th, 2025, Unichain Sepolia Planned maintenance will be carried out to enable the no license fault proof feature, which the developers plan to integrate on the first day of the mainnet launch. No license failure proof is required to enable any participant to verify the current state of the memory blockchain and challenge illegal fund extraction operations, thereby improving network security. Fault proof, as a mechanism in the Ethereum Layer 2 network, allows users to challenge potential fraudulent behavior or erroneous transactions.

After completing maintenance and security verification, the Unichain mainnet will be open to the public. This stage will allow users to bridge their funds to the network and begin using applications built on Unichain. After the main network is launched, new features are also planned, including the highly anticipated Flashblocks, which can shorten block generation time to 250 milliseconds and enable transactions to be completed almost instantly.

Unichain also plans to launch the decentralized validation network Unichain Validation Network (UVN) to address the risks associated with single sorter architectures. Uniswap represents, UVN Allowing nodes to validate memory blocks will add an additional layer of finality and reduce the risk of conflicting or invalid memory blocks. To become a validator in UVN, node operators must stake UNI on the Ethereum mainnet.
