Ethereum Research Channel, in Buterin’s Monday Post suggestive Merkle Tree and Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge (ZK-SNARK) were more complex methods of stealth addresses for ERC-721 tokens, but he proposed his own solution. Instead, the Ethereum co-founder has proposed that his wallet could contain a method that allows senders to essentially mask their addresses to third parties.

For example, you can: Send an NFT to Vitalik.eth so that no one but me (the new owner) can see who the new owner is, Buterin said. said.

Buterin speculated that when using this method, the sender would need to include enough ETH to pay the fee 5-50 times through the transfer chain. However, he added, “there may be a more general solution that somehow uses specialized searchers and block builders.”

Buterin will speak at Korea Blockchain Week, August 7-14.
