Use Cases Of ZKP

Zero-knowledge proofs (ZKPs) have a variety of use cases across industries. They provide a method of proving knowledge without revealing sensitive information, making them ideal for applications that require privacy and security. Here are five common use cases for ZKPs:

Anonymous payments:

ZKPs can be used for anonymous transactions, which can be valuable in situations where parties want to protect their identities. One example is the cryptocurrency Zcash, which uses ZKPs to shield the details of transactions while still allowing them to be verified.

Another example is the AZTEC Protocol, which uses ZKPs to enable private transactions on Ethereum. This allows users to transfer ERC20 tokens without revealing the amounts or addresses involved.

Decentralized identity and authentication:

ZKPs can also be used for decentralized identity and authentication. They allow users to prove their identity without revealing any personally identifiable information. One example is the Sovrin Network, which uses ZKPs to enable self-sovereign identity on a public blockchain. Civic, which uses ZKPs, provides a more secure and privacy-focused alternative to traditional identity verification methods that rely on centralized databases storing sensitive personal information.

Verifiable computation:

ZKPs can be used for verifiable computation, where computation is performed on sensitive data without actually revealing the data. One example is Enigma, a decentralized data marketplace that uses ZKPs to allow computations to be performed on encrypted data.

StarkWare uses ZKPs to develop two distinct products: StarkEx, which is a permissioned Validity-Rollup that can function on its own, and StarkNet, a permissionless decentralized ZK-Rollup.

Highly scalable and secure layer 2s

KPs can be used for highly scalable and secure layer 2 solutions, which are needed for blockchain networks to scale to support large numbers of users. One example is the company Loopring, which uses ZKPs to enable high-throughput, non-custodial trading on Ethereum.
