TORN is an ERC20-compatible token with a fixed supply that governs Tornado Cash, TORN holders can make proposals and vote to change the protocol via governance.
Users who have believed in Tornado Cash from early on should have a say in governing the protocol. For this reason, early adopters of the protocol did receive an airdrop of TORN.
TORN has been airdropped to [all addresses](https://github.com/tornadocash/airdrop/blob/master/airdrop.csv) that made deposits into ETH pools before block `11400000`. TORN were airdropped in the form of a non-transferable TORN voucher (vTORN) that can be redeemed 1:1 to TORN within 1 year, from December 18, 2020, to December 18, 2021. TORN that aren’t redeemed will be swept into the governance contract after 1 year and become part of the DAO Treasury. Redeemed TORN will be available immediately.
The airdropped amount depends on users’ deposit size and age — larger deposits and older deposits will receive more TORN. Multipliers for deposit size are logarithmic:
So a 100 ETH deposit get twice as many tokens as a 1 ETH deposit. The multiplier allows large and small users of Tornado Cash to both have a say in governance.
