Smart Contract

ELI5 — The Vibe Check

Code that runs on a blockchain — once deployed, nobody can change it (which is either amazing or terrifying). It automatically executes when conditions are met, like a vending machine: put money in, get thing out, no middleman. The terrifying part: if there's a bug, you can't patch it.

Real Talk

A smart contract is a self-executing program stored on a blockchain that automatically enforces the terms of an agreement. They're primarily written in Solidity (Ethereum) or Rust (Solana). Once deployed, they're immutable — bugs require deploying a new contract and migrating state.

Show Me The Code

// Solidity smart contract (simplified)
contract SimpleStorage {
    uint256 private value;
    
    function set(uint256 _value) public {
        value = _value;
    }
    
    function get() public view returns (uint256) {
        return value;
    }
}
// Once deployed: permanent, immutable, unstoppable
