Vitalik Buterin Says There May Be “Low-Tech Approach” To Incorporate Privacy Features Into NFT

Vitalik Buterin, the co-founder of Ethereum, has suggested there may be a “low-tech approach” to incorporating privacy features into nonfungible token (NFT) transactions.

It has been reported that Buterin implied Merkle trees and Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge (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.

He said:

“You would be able to eg. send an NFT to vitalik.eth without anyone except me (the new owner) being able to see who the new owner is.”

However, Buterin posited that using this method, senders would need to include “enough ETH to pay fees 5–50 times” through the transfer chain. He added that “maybe there is a better generic solution that involves specialized searchers or block builders somehow.”

The report said that 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, it was reported that there were cases of users swiping IP addresses off of NFT marketplace OpenSea as well as MetaMask.

Thus, Buterin has been speaking at Korea Blockchain Week from Sunday (August 7) through Sunday (August 14).
