How Do Smart Contracts Handle Transactions?
Smart contracts on the Ethereum blockchain are self-executing contracts with the terms of the agreement directly written into code. They identify, verify, and enforce transactions, eliminating the need for intermediaries. When a smart contract is deployed, it is assigned a unique address on the Ethereum network.
Transactions involving smart contracts start when users send Ether or tokens to the smart contract's address. The contract then processes the transaction based on predetermined rules coded within it. The Ethereum Virtual Machine (EVM) executes the contract's code, validating conditions and ensuring that funds are transferred only if certain criteria are met.
Each transaction requires a gas fee, which compensates miners for their computational work. The gas price is set by the users, influencing transaction speed and cost. Once executed, the results are recorded on the blockchain, ensuring transparency and permanence. This automated approach significantly reduces the risk of fraud and enhances trust among parties involved.
Additionally, developers can use various programming languages, like Solidity, to create complex agreements that include multiple conditions and functions. This flexibility allows for a wide range of applications, from financial agreements to decentralized applications (dApps).
