ETH: Tornado Cash Notes Not Yet Withdrawn (ETH Pools)
Shown as its 2019–2022 sample; the latest readings and full history are included with Plus.
The number of deposits waiting in each of Tornado Cash's ETH pools: deposits made so far less withdrawals made so far, per denomination.
Why use it. The size of the waiting set is what gives a mixer its privacy: the more notes in a pool, the harder any one withdrawal is to link back to a deposit. How to read it. Each line is one denomination. Rising lines mean deposits are arriving faster than they leave; a sharp fall means the pool was drained, shrinking its anonymity set.
Calculation. Tornado Cash's instances on Ethereum mainnet (ETH, DAI, USDC, USDT and WBTC, each in fixed denominations), from their Deposit and Withdrawal events on CryptoKeyhole's own node. A deposit or withdrawal moves exactly one denomination of the pool. US dollar stablecoins count at face value, ether and wrapped bitcoin at the day's close of CryptoKeyhole's ETH/USD and BTC/USD indexes; the DAI-derivative (cDAI) instances are counted as notes but carry no dollar value. Only totals are computed: no address is stored or shown. Deposits and withdrawals are observed from each pool's own events; pools the protocol has retired stay in the totals, and activity on other networks is not included.
