zkSync is an Ethereum-based protocol that uses cryptographic validity proofs to make transactions faster and more cost-effective. Operating as a ZK rollup, most data and computation are done off-chain while still maintaining high levels of security through validation on the Ethereum mainchain. This technology has great potential for improving cryptocurrency transaction efficiency at reduced costs compared to traditional methods.
