“You would be able to eg. send an NFT to vitalik.eth without anyone except Maine (the new owner) having the ability to see who the new owner is,” said the Ethereum co-founder.
Ethereum co-founder Vitalik Buterin has steered there is also a “low-tech approach” to incorporating privacy options into nonfungible token, or NFT, transactions.
In a Monday post on the Ethereum research channel, Buterin silent Merkle trees and Zero-Knowledge summary Non-Interactive Arguments of data, or zk-SNARKs, were a a lot of difficult method for stealing addresses for ERC-721 tokens whereas proposing his own answer. The Ethereum co-founder steered instead that sensible contract wallets may embrace a method that may allow the sender to basically mask their address to third parties.
“You would be able to eg. send without NFT to vitalik.eth while not anyone except me (the new owner) being able to examine who the new owner is,” said Buterin.
Buterin posited that using this method, senders would need to include “enough ETH to pay fees 5–50 times” through the transfer chain. However, he other that “maybe there's an improved generic answer that involves specialised searchers or block builders somehow.”
