Smart Contracts

How Do Smart Contracts Work?
Like any other contract, a smart contract is a binding contract between two parties. It uses code to take advantage of blockchain technology, thereby unlocking greater effectiveness, openness, and confidentiality. The execution of smart contracts is controlled by relatively easy "if/when/then" statements written in code on the blockchain.

One smart contract can have multiple different conditions and one application can have multiple different smart contracts to support an interconnected set of processes.

Here are the steps needed for the functioning of smart contracts:

       
  • Contract agreement: The parties wanting to conduct business or exchange services must agree on the arrangement's terms and conditions. They must also determine how a smart contract will operate, including the criteria that must be achieved for the agreement to be fulfilled.
  •    
  • Contract creation: Participants in a transaction may create a smart contract in many ways, including building it themselves or collaborating with a smart contract provider. The provisions of the contract are coded in a programming language.
  •    
  • Contract deployment: When the contract has been finalized, it must be published on the blockchain. The smart contract is uploaded to the blockchain in the same way as regular crypto transactions, with the code inserted into the data field of the exchange. Once the transaction has been verified, it's deemed active on the blockchain and cannot be reversed or changed.
  •    
  • Monitoring conditions: A smart contract runs by tracking the blockchain or a different reliable source for predetermined conditions or prompts. These triggers can be just about anything that can be digitally verified, like a date attained, a payment made, etc.
  •    
  • Execution: When the trigger parameters are met, the smart contract is activated as per the "if/when/then" statement. This may implement only one or multiple actions, like passing funds to a seller.
  •    
  • Recording: Contract execution results are promptly published on the blockchain. The blockchain system verifies the actions taken, logs their completion as an exchange, and stores the concluded agreement on the blockchain.
