Smart contracts are computer programs that automatically enforce the terms of an agreement on a blockchain, such as Ethereum. They are written in a high-level programming language and compiled into bytecode, which is then stored on the blockchain.
Here are some ways smart contracts work on Ethereum:
Execution
Smart contracts are self-executing, meaning they run automatically when the conditions set by the parties involved are met. For example, a smart contract could issue a token when someone deposits money.
Code
The code for a smart contract contains a set of rules that outline how the parties to the contract will interact.
Compatibility
EVM-compatible smart contracts are software that can be understood by the Ethereum blockchain’s computing state.
Smart contracts can offer many benefits, including:
Speed and efficiency: Smart contracts can process transactions more efficiently than traditional contracts.
Security: Smart contracts can increase security.
Transparency: Smart contracts can offer more transparency than traditional contracts.
Cost savings: Smart contracts can reduce transaction costs associated with traditional contracts.
