Abstract: Public blockchains have a privacy problem for which we have many tools from Cryptography to solve. How can fully homomorphic encryption and threshold cryptography augment zero-knowledge proofs? This talk presents a framework of structuring zero-knowledge, transparent, and confidential (homomorphic) computation codenamed PESCA. We present two case studies: privacy in DeFi and NFT auctions.
The talk expands on ideas from Navigating Privacy on Public Blockchains and is followed by PESCA: A Privacy-Enhancing Smart Contract Architecture (Draft).
List of informal posts discussing topics of interest to me. They could contain academic or industry surveys, personal opinions, or novel ideas waiting for further developments (or not). In these posts, all opinions discussed are my own, and any information provided is not investment advice.
