Zcash at the Federal Reserve Bank of St. Louis () @stlouisfed Document: An Introduction to Zero-Knowledge Proofs in Blockchains and Economics (Federal Reserve Bank of St. Louis Review, Fourth Quarter 2023) URL: Mentions: "Existing applications are the privacy-protecting cryptocurrency Zcash and the Tornado cash protocol on Ethereum (see Nadler and Schaer, 2023)." "Zcash, introduced by Ben Sasson et al., 2014, is probably the most famous cryptocurrency that leverages ZKPs for private transactions." Context: Zcash is prominently featured as a flagship example of zero-knowledge proofs (ZKPs) in blockchains, enabling private transactions by hiding details (e.g., sender, amount) via commitments, nullifiers, and zk-SNARKs while proving validity. It contrasts with transparent ledgers like Bitcoin and is discussed for applications in data confidentiality and economic incentives.
