The number of technologies leveraged to improve privacy on the base layer of Ethereum's ($ETH) blockchain continually grows, as CoinDesk's Christine Kim notes, includeing: mixers, computational data layers, and zero-knowledge proofs. In this piece, Christine explores the burgeoning efforts to improve Ethereum's privacy (something that might seem like an oxymoron in blockchain parlance) and work to build what Itamar Lesuisse, the CEO and co-founder of crypto wallet tool Argent, describes as an issue for even “the most simplest use case” on Ethereum. In short, many privacy technologies for Ethereum are experiments that might work now but are not guaranteed for the future, or even the exact opposite--something that is not usable now but can be in the future.
