According to news on December 21, Unichain released a phased roadmap for its main network and announced that the main network will be launched in early 2025. The mainnet will support permissionless fault proofs (Permissionless Fault Proofs) from the first day of launch, ensuring that on-chain activities can be verified, further improving security and decentralization. The roadmap specifically includes: 1 Testnet stage: The Sepolia testnet is currently open, and infrastructure providers are testing; 2 Mainnet launch: The mainnet plans to start enabling the permissionless fault proof function on January 6, 2025, and will be fully open after the functional verification is completed; 3. Experimental test network: After the main network is launched, the testing and development of new functions will continue to be promoted.
