StarkWare Unveils New 'Stwo' Cryptographic Prover That's 'Blazingly Fast'

A prover is a key component for layer-2s, since they generate proofs that are then posted to the base layer blockchain – a crucial process in linking the networks and sharing the security. With a faster prover, processing transactions costs should be lower, which in effect then will also lower fees for users and speed up transactions, according to the StarkWare team.
