Quick TakeZero knowledge projects utilize zk proofs to compress data and reduce the computation required for verifiers to validate transactionsThe two main value propositions for utilizing zk proofs are scaling transaction throughput and conferring privacy for usersApart from the notable names like StarkWare and Matter Labs, there are a number of zk-based projects which have seen increased media attentionUnlike StarkWare and Matter Labs, there are some zk-based blockchain projects which have decided to build their own layer 1 chainsMany of these zk-based projects have innovative use cases for validity proofs, which allows them to invent some unique features in the blockchain domain
