According to the official announcement of Base, Base has launched multiple new technologies aimed at improving on-chain transaction speed, scalability, and user experience. Among them, the Flashblocks technology has been launched on the Base Sepolia testnet, reducing block confirmation time from 2 seconds to 200 milliseconds, making it the fastest EVM chain.

In addition, Base has also introduced Base Appchains (L3 chain) to provide exclusive block space for high-traffic applications, improving scalability. At the same time, Base has introduced Smart Wallet Sub Accounts to optimize user experience, reduce the number of transaction signatures, and provide a more secure account management method. Base plans to launch Flashblocks and Sub Accounts on the mainnet in Q2.
