Understanding Tornado.cash Transactions
How Tornado.cash Works:
Tornado.cash is a decentralized, trustless and privacy-preserving mixer protocol built on the Ethereum blockchain. It aims to provide users with enhanced financial privacy by obscuring the origin, destination, and amount of transactions. Briefly, when a user wants to make a private transaction using Tornado.cash, they deposit their Ethereum into the smart contract. The smart contract then mixes this Ether with other deposited funds before distributing it back to the user in a random transaction output, ensuring the privacy of both sender and receiver. The functionality of Tornado.cash can be broken down into several steps:
Deposit:
The user initiates the transaction by sending Ether to Tornado.cash’s contract address.
Mixing:
The Ether is then mixed with other funds, breaking the link between the input and output addresses.
Withdraw:
The user can withdraw their mixed funds at any time, which are now indistinguishable from other transactions on the Ethereum blockchain.
Identifying Tornado.cash Transactions on Ethereum Blockchain:
Identifying transactions involving Tornado.cash can be a challenging task due to its privacy-preserving nature. However, there are several tools and resources available for tracking these transactions:
Blockchain Explorers:
Services like link and link can be used to search for transactions on the Ethereum blockchain. While they cannot directly reveal Tornado.cash transactions, they do provide information about inputs and outputs of regular Ethereum transactions.
Analytical Tools:
Some analytical tools and services, like link, can help in identifying patterns or clusters that might indicate the presence of Tornado.cash transactions.
The Challenges:
Discussing the challenges in identifying Tornado.cash transactions lies mainly in the use of advanced cryptographic techniques like zk-SNARKS for privacy. zk-SNARKS (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) enable Tornado.cash to prove that a transaction has occurred without revealing any information about the involved parties or the amount being transacted.
