PANews December 21 news, Uniswap L2 network Unichain announced the mainnet development roadmap, which is scheduled to officially launch early next year. Since the launch of the Unichain Sepolia testnet in October, the network has processed 50 million test transactions and over 4 million test contracts. The Sepolia testnet is now public, and infrastructure providers are actively testing the mainnet. After the mainnet goes live, it will continue to promote decentralization and performance improvements through new features. These features will first be launched on the experimental testnet for stability and performance testing, then moved to Sepolia for broader testing, and finally launched on the mainnet. The first feature on the public experimental testnet is Flashblocks, which will reduce effective block time to 250 milliseconds, allowing transactions to be completed instantly. The Unichain validation network will also be launched on the experimental testnet, and the community will be invited to run test validation nodes.
