EIP-712: Quick Intro and Use case
Abstract
This is a standard for hashing and signing of typed structured data as opposed to just bytestrings. It includes a
aToken / yield-generating tokens
AToken uses a unit increase model, meaning a holder’s balance of aTokens will increment up as the asset pool grows from interest payments made by borrowers. For example, if you deposit 1 ETH in the Aave ETH pool you’ll be minted 1 aETH token. As the pool accumulates interest your aETH token balance will increment up so that your aETH token balance is greater than 1, reflecting your claim on a growing pool of assets. When an aETH token holder goes to redeem the underlying ETH their aETH will be redeemed 1:1 with the underlying ETH.
How Tornado Cash works
Tornado Cash is a coin mixer that you can use to anonymize your Ethereum transactions. Because of the logic of the blockchain, every transaction is public. If you have some ETH on your account, you cannot transfer it anonymously, because anybody can follow your transaction history on the blockchain. Coin mixers, like Tornado Cash, can solve this privacy problem by breaking the on-chain link between the source and the destination address by using ZKP.
