Ethereum co-founder Vitalik Buterin has suggested there may be a “low-tech approach” to incorporating privacy features into nonfungible token, or NFT, transactions.
In a Monday post on the Ethereum research channel, Buterin implied Merkle trees and Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge, or zk-SNARKs, were a more complicated method for stealth addresses for ERC-721 tokens while proposing his own solution. The Ethereum co-founder suggested instead that smart contract wallets could include a method that would allow the sender to essentially mask their address to third parties.
