Flashblocks feature is now available on the GIWA Chain.

Flashblocks provides preconfirmation signals that offer rapid feedback on submitted transactions before the next block is sealed. With flashblocks, users can receive updates within just a few hundred milliseconds (up to \~200ms), enabling significantly more responsive experiences in wallets, payment services, games, and other real-time applications.
