Zero-knowledge proofs (ZKPs) have a particularly important history in the context of cryptocurrencies since their inaugural implementations in Zerocoin and Zerocash. While early implementations targeted general privacy, ZKPs are only now beginning to be harnessed for many other powerful functionalities besides mere obfuscation. For example, zkRollups enable greater transaction throughput on Ethereum, and recursive proof constructions such as Halo are being used to create a compressed blockchain. Proposals such as Proof-of-Necessary Work leverage the capabilities of zkSNARKs to provide security at the consensus layer of the network, and with constructions such as Zexe, ZKP’s enable off-chain computation and even entirely new programming models. Zero knowledge proofs are often referred to monolithically, but it’s important to remember that there are many different types of ZKPs. Strictly speaking, a ZKP scheme is one that provides the property of “zero-knowledge”, where the verifier of a
