Vitalik Buterin offers stealth addresses for anonymous NFT ownership

"You could e.g. send an NFT to vitalik.eth without anyone but me (the new owner) seeing who is the new owner,” said the Ethereum co-founder.

Ethereum co-founder Vitalik Buterin suggested there could be a "low-tech approach" to incorporating privacy features into non-fungible token, or NFT, transactions.

In a Monday post on the Ethereum search channel, Buterin suggested that Merkle trees and zero-knowledge non-interactive succinct knowledge arguments, or zk-SNARKs, were a more complicated method for stealth addresses of ERC-721 tokens while offering its own solution. Instead, the Ethereum co-founder suggested that smart contract wallets could include a method that would allow the sender to essentially hide their address from third parties.

“You could e.g. send an NFT to vitalik.eth without anyone but me (the new owner) being able to see who the new owner is,” Buterin said.

Idea: Stealth addresses for ERC721s.

A low-tech approach to adding a significant amount of privacy to the NFT ecosystem.

Buterin posited that using this method, senders should include "enough ETH to pay the fee 5-50x" throughout the transfer chain. However, he added that "there may be a better generic solution that somehow involves specialist researchers or block builders".
