Bitcoin’s (BTC) Gavin Andresen Explains How To Use Ethereum (ETH) Mixers


Contents

Namely, he addressed the use-cases of the Tornado.cash Ethereum (ETH) smart contract for anonymous Ethereum (ETH) transactions.


Tornado: too complicated ‘for mere mortals’


First of all, Mr. Andresen gave his kudos to the developers of Tornado, which is ‘wicked-smart’. The Bitcoin developer appreciated the usage of “Zero-Knowledge Succinct Non-Interactive Argument of Knowledge” cryptography (ZkSNARK), the one of cutting-edge technologies in blockchain privacy.



Mr. Andresen noted, with great disappointment, that Tornado users rarely follow the manuals from the developers of this mixer. He described the user experience of an average Joe sarcastically:


So you decide to run those 117 ETH through tornado into a brand-new wallet named “SuperSecret” that you create offline in an electromagnetically sealed room on a brand new laptop that has never touched the internet … and you have almost certainly accomplished nothing.  


This lack of anonymity is caused by the correlation between the amounts of deposited and withdrawn tokens. In turn, the recipient is able to find information about the sender’s wallets and funds.

According to Mr. Andresen, the right way to use an Ethereum (ETH) mixer is to deposit much more coins into it than you plan to send to the final address. 


Another wallet or another blockchain?


Moreover, Mr. Andresen said that the level of anonymity provided by such mixers shouldn’t, itself, be overestimated. He explained that Tornado is ‘a fantastic building block that will let some clever developers build a much more private Ethereum wallet’.


At the moment, he recommended using Monero and ZCash (with only ‘shielded’ addresses) or at least to shuffle your funds via the wallets of centralized exchanges.
