EVM Deep Dives: The Path to Shadowy Super Coder 🥷 💻 - Part 1

✅ EVM selects functions IF and FOR

1. Get the function calldata(CALLDATALOAD)

2. Remove the waste data when checking the function identifier(SHR)

3. If the checking is true ⇒ go to the destination offset(JUMPI)

                              false ⇒ checking the other function identifiers
   

• solidity-code and bytecode

Opcodes are 1 byte in length leading to 256 different possible opcodes. The EVM only uses 140 unique opcodes.

This is the calldata of ("store(uint256)", 10)

0x6057361d000000000000000000000000000000000000000000000000000000000000000a

keccak256(“store(uint256)”) → first 4 bytes = 6057361d
