PANews reported on December 21 that Uniswap L2 network Unichain announced the mainnet development roadmap, and the mainnet will be officially launched early next year. Since the launch of the Unichain Sepolia testnet in October, 50 million test transactions and more than 4 million test contracts have been deployed on the network. The Sepolia testnet is now public, and infrastructure providers are actively testing the mainnet. After the mainnet is launched, decentralization and performance improvements will continue to be promoted through new features. These features will first be launched on the experimental testnet for stability and performance testing, then transferred to Sepolia for more extensive testing, and finally launched on the mainnet. The first feature on the public experimental testnet is Flashblocks, which will reduce the effective block time to 250 milliseconds, making transactions instant. The Unichain verification network will also be launched on the experimental testnet, and the community will be invited to run test verification nodes.
