Are smart contracts stored on the Blockchain?

Smart contracts are lines of code that are stored on a blockchain and automatically execute when predetermined terms and conditions are met. At the most basic level, they are programs that run as they’ve been set up to run by the people who developed them.

The autonomous nature of smart contracts means you can expect huge improvements on traditional systems in terms of speed, cost, security, accuracy and transparency.

How does smart contract work in Blockchain?

A smart contract is an agreement between two people in the form of computer code. They run on the blockchain, so they are stored on a public database and cannot be changed. The transactions that happen in a smart contract are processed by the blockchain, which means they can be sent automatically without a third party.

What are smart contracts good for?

Smart contracts are computer programs stored in a blockchain. They can be used to automate the unstoppable transfer of crypto-tokens between users, according to agreed-upon conditions.
