ZK Proof technology is being applied across various blockchain use cases, from privacy-focused cryptocurrencies to scalability solutions.
Projects like Mina and Loopring are using ZK proofs to address blockchain scalability issues in innovative ways.
Worldcoin's application of ZK proofs for identity verification demonstrates the technology's potential beyond financial transactions.
The world of blockchain technology continues to evolve, with Zero Knowledge (ZK) Proof projects at the forefront of innovation. These are projects that are solving very fundamental concerns related to privacy and the scale of blockchains in the cryptocurrency arena. Looking at the following five examples of exciting ZK Proof projects in the industry at the moment.
Zcash: Pioneering Privacy-Focused Cryptocurrency
Zcash had been one of the first to start incorporating ZK-SNARKs into its consensus algorithm, upon release. Unlike many other blockchain networks, this privacy-oriented cryptocurrency enables users to protect information about their transactions. Critically, the utilization of ZK proves that Zcash is outstanding in the world of cryptocurrency as a method of maintaining privacy.
Mina: The Lightweight Blockchain
Mina has drawn interest for being different from the other blockchains in terms of size. Likewise, for Mina, the blockchain size is kept around 22 kilobytes constant, and recursive ZK proofs are employed. The improvement in scalability makes the nodes easier to run and may thus lead to increased use of blockchain.
DYDX: Decentralized Trading with Privacy
DYDX has applied ZK-proof technology to decentralized finance (DeFi). This project allows the trading of perpetual contracts with other traders without a central counterparty and with improved anonymity. Thus, plugging into ZK proofs, DYDX plans to offer a decentralized trading platform that addresses the lack of privacy and anonymity orientation typical of centralized exchanges.
Loopring: Scaling Ethereum with ZK-Rollups
Loopring has focused on addressing Ethereum's scalability issues through ZK-Rollups. This layer 2 scaling solution helps enable users to trade and make payments in the Ethereum network efficiently, and cheaply. The use of ZK proofs by Loopring may help Ethereum to increase its throughput by several folds.
Worldcoin: Global Identity and Universal Basic Income
Worldcoin presents an ambitious project combining ZK proofs with biometric technology. The project seeks to establish an identity and financial system of the world, possibly to pay some amount of unconditional basic income. Notable among the application of ZK proofs is the Worldcoin which uses iris scanning in identification which is considered controversial but an attractive use of ZK proofs as it ensures user anonymity during the identification processes.
