A smart contract is a computer program that automatically executes when certain predefined conditions are met. These contracts are stored on a blockchain, ensuring their transparency, security, and immutability. Here is a more detailed explanation:
Features of Smart Contracts
Automation: Smart contracts execute automatically without the need for intermediaries. This reduces the risk of human error and increases efficiency.
Transparency: By being on a blockchain, the terms and conditions of the contract are visible to all parties involved, ensuring transparency.
Immutability: Once a smart contract is deployed on the blockchain, it cannot be altered. This ensures that the terms of the contract cannot be changed after its creation.
Security: Smart contracts use cryptography to secure transactions and protect data.
How Smart Contracts Work
Definition of Conditions: The conditions under which the contract will be executed are defined. For example, "If A sends 1 ETH to B, then B will send 10 tokens to A."
Deployment on the Blockchain: The smart contract is deployed on the blockchain, where it is stored immutably.
Automatic Execution: When the predefined conditions are met, the smart contract executes automatically, performing the corresponding transactions.
Use Cases
Decentralized Finance (DeFi): Smart contracts are used to create decentralized financial applications, such as loans and exchanges.
Insurance: Smart contracts can automate the payment of insurance claims when certain conditions are met.
Supply Chain Management: They can automatically track and verify the movement of goods along the supply chain.
