Vitalik Buterin suggested using hidden addresses for anonymization of Ethereum users – Bits Media

The co -founder of the Ethereum announced the need to find a solution for the confidentiality of the network, Since all the information, contained in the blockchain, By default, it is publicly available.

Vitalik Buterin called this a task, which can solve hidden addresses, capable of making peering transactions, transmission of non -replaced tokens and registration in the system of domain names of the Ethereum (TO US) anonymous, Protecting user data.

The recipient of crypto acts can create and save the "key of expenses", which will then be used to create a hidden meta-address. Address, which can be registered in ENS, It is transmitted to the sender, which cryptographically calculates meta-address to create a hidden address, belonging to the recipient. Then the sender can transfer crypto assets to the hidden address of the recipient in addition to the publication of a temporary key to confirm, that the hidden address belongs to the recipient. As a result, a new hidden address is created for each transaction.

Buterin noted, that along with the mechanism of hiding the keys, you need to use the exchange protocol, comparing unique open key addresses. This will allow you to disguise the connection between the hidden address and the user's meta address. The co-founder of the Ethereum mentioned the technology of evidence with the zero disclosure of ZK-Snark, which can also increase transaction confidentiality. However, he noted, that in this case, even one transaction may require a large amount of additional gas.

According to Butaterin, The proposed concept of hidden addresses provides confidentiality, different from that, which gives the cryptocurrency mixer Tornado Cash. I got to the sanctions list of US Foreign Assets Office (I DO IT) Tornado Cash can hide translations of the main interchangeable cryptoactives, Whether ETH or other altcoins based on ERC-20. However, it is difficult for a mixer to ensure the confidentiality of transactions with little-known cryptoactives based on ERC-20, And this is relevant for NFT translations, assures Buterin.

“Today, basic hidden addresses can be implemented quite quickly, and they will significantly increase the confidentiality of the etherium. Of course, Support will require certain work by the wallet. Nonetheless, I find, that wallets should develop a model with several addresses ", - the co -founder of ETH argues.

Vitalik Buterin recently spoke about the prospects of ZK-Stark and suggested, what through 10-20 years, this technology will occupy the same important place, Like blockchain. Besides, The co -founder of the Ethereum considers, that the creation of stablecoins resistant to inflation and Internet access will become important achievements in the crypto industry.
