Ethereum founder Buterin wants to implement stealth addresses
In a tweet from early August, Ethereum founder Vitalik Buterin suggested a “low-tech approach” to include privacy features in non-fungible tokens (NFTs), or NFT transactions. Buterin expressed the idea of introducing cryptographic addresses into the current Ethereum token standard for NFTs, ERC-721, and linked it to the ethresear.ch page in his post.
At ethresear.ch, Anton Warstater, a researcher and lecturer at the Institute for Distributed Ledgers and Token Economics, previously reported on the idea of hidden addresses. His idea was inspired by a blog post by Ethereum founder Buterin in January. Wahrstätter explains that by implementing stealth addresses, users are able to cast and burn NFTs with relative anonymity.
More anonymity through incognito addresses
“An idea: incognito addresses for ERC721s. A low-tech way to add a great deal of privacy to the NFT ecosystem. For example, you can send an NFT to dynamic.eth without anyone but me (the new owner) being able to tell who it is,” Buterin said on Twitter. The new owner is.

A cryptic address is a unique wallet address that is used to create further anonymity in transactions. While normal wallet addresses are publicly visible and transactions can be traced back to that address, a cryptic address acts as a kind of proxy for your private wallet address.
Buterin suggests using smart contract wallets as a possible solution
In response to Wahrstätter’s proposal at ethresear.ch, which included Merkle trees and zero-summarized non-interactive knowledge arguments, or zk-SNARKs in short, Buterin explained that this involved a more complex method for stealth addresses for ERC-721 tokens and proposed a solution of his own: According to Buterin, it could That smart contract wallets include a method that would allow the sender to essentially hide their address from third parties.
However, according to Buterin, one challenge remains figuring out how to pay the fee. “The best thing I can think of is if you send someone ERC721, they also send enough ETH to pay a 5-50x fee to send it. If you receive ERC721 without enough ETH, you can send some of the ETH that was put into it to keep it,” Buterin said. “. However, according to the Ethereum founder, there may be a “better overall solution that somehow involves specialized researchers or block builders.”
After Wahrstätter and Buterin circulated the idea further on ethresear.ch and other users also joined the discussion and asked questions, Buterin clarified a few days later: “Now that I think about it more, I realize that it doesn’t really make sense to keep this standard part of ERC721 By itself. There are many potential use cases for it. So it is likely that ERC is independent, allowing users to create new addresses owned by other users, and both ERC721 and other applications can use this ERC token.” Further: “Apart About that, my main comment on the EIP so far is that I hope something like the idea of how to create a StealthAddress from my previous post will be added so that we can support smart contract wallets.”
Criticism of Buterin’s idea
However, some users have also expressed concerns about Buterin’s co-signing of stealth titles, according to Nft Now. For example, stealth titles can provide a way for thieves and other ill-intentioned actors to make recovering a stolen NFT nearly impossible. It will be more difficult to track down stolen NFTs without a publicly available address for investigators to display on the blockchain.
Another argument is that Buterin’s idea runs counter to one of the fundamental principles of blockchain technology, which is the creation of a new decentralized economy based on publicly available records.
