Vitalik Buterin proposes stealth addresses for anonymous NFT ownership
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.
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 added that “maybe there is a better generic solution that involves specialized searchers or block builders somehow.” Finding the balance between semi-anonymity and transparency on the blockchain has been a challenge for many as the crypto space continues to grow. In January, Cointelegraph reported there were cases of users swiping IP addresses.
