A Zero-Data Proof (ZKP) is a cryptographic approach that enables one occasion to show to a different {that a} sure assertion is true—with out revealing any particular details about the assertion itself. This idea is key to enhancing privateness on public blockchains.
For instance, a consumer might show they’ve sufficient funds for a transaction with out revealing their precise pockets steadiness. ZKPs are the muse of applied sciences like zk-SNARKs and zk-STARKs, that are extensively utilized in privacy-focused tasks resembling Zcash and a few Ethereum Layer 2s.
ZKPs are additionally very important for scaling blockchain networks. By bundling transactions right into a single proof, networks can validate hundreds of operations with minimal on-chain information. This enhances each privateness and effectivity—a uncommon mixture in blockchain design.
