HicssEIP-712: Quick Intro and Use case
https://eips.ethereum.org/EIPS/eip-712 Abstract This is a standard for hashing and signing of typed structured data as opposed to just bytestrings. It includes a theoretical framework for correctness of encoding functions, specification of structured data similar to and compatible with Solidity structs, safe hashing algorithm for instances of those structures, safe inclusion of those instances in the set of signable messages, an extensible mechanism for domain separation, new RPC call eth_sig...
HicssHow 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.Deposit:Users deposit the same amount of ET...

delegatecall is a low level function similar to call.When contract A executes delegatecall to contract B, B's code is executed with contract A's storage, msg.sender and msg.value.
So we get a method to update the contract.
Example Code:
