π Ethereum Smart Contracts 101:
What are Ethereum Smart Contracts? They are like regular contracts, but stored and run on the Ethereum blockchain. These digital agreements automatically execute when specific conditions are met, without needing a middleman. Think of them as self-executing computer programs that manage digital assets.
They are the backbone of decentralized applications (dApps) and cryptocurrencies beyond just Ether. Developers use languages like Solidity to write these contracts, defining how value moves securely. Once deployed, they are immutable and transparent, meaning everyone can see the rules, but no one can change them.
π Key AI Concepts Explained:
1. Decentralization: This concept means no single person or company controls the network, making it more resistant to censorship or shutdowns. It ensures the contract operates fairly without a central authority approving or denying actions.
2. Immutability: Once a smart contract is launched on Ethereum, its code cannot be changed or deleted. This provides a high level of trust, as everyone knows the rules will remain constant.
3. Consensus Mechanism: This is how all the computers on the Ethereum network agree that a transaction or contract execution is valid. It ensures that everyone has the same, correct version of the blockchain.
π Words to Know:
1. Blockchain: A secure, public record of transactions shared across many computers.
2. Solidity: The main programming language used to write Ethereum smart contracts.
3. dApp: A decentralized application that runs on a blockchain, using smart contracts.
π― Imagine This:
