What Is A Smart Contract?

Published on:

Smart contracts are software programs that run on a blockchain when specific criteria are fulfilled. They’re frequently employed to automate the execution of a contract, so that all parties know the outcome immediately and without the need for an intermediary. They may also be used to automate a process by triggering the next step when conditions are satisfied.

How smart contracts work

Smart contracts are computer programs that execute “if/when…then … statements” written into code on a blockchain. When the conditions have been fulfilled and verified, the network of computers performs the operations. Such actions as releasing funds to the correct people, registering a vehicle, sending notifications, or issuing a ticket are possible. When the transaction is completed, the blockchain is updated. As a result, no one has authority to change it, and only authorized persons may see the outcomes.

A smart contract can have as many stipulations as needed to satisfy the participants that the task will be completed satisfactorily. To establish the terms, participants must agree on how transactions and their data are represented on the blockchain. They must also agree on the “if/when…then…” rules that govern those transactions, explore all possible exceptions, and define a framework for resolving disputes.

Then, the smart contract can be programmed by a developer. However, nowadays there are many organizations that use blockchain technology for business who provide templates and online tools to make it easier to structure smart contracts.

Smart contracts offer a number of advantages.

Speed, efficiency and accuracy

When a condition is met, the contract is immediately completed. Because smart contracts are digital and automated, there’s no paper to deal with or time to correct mistakes that frequently occur when people fill in forms manually.

Trust and transparency

Because there’s no third party, and because transactions are recorded in an encrypted format that is shared among all participants, you don’t have to worry about information having been modified for personal gain.


The transaction records on the blockchain are secured, making them extremely difficult to tamper with. Furthermore, because each record is linked to the preceding and following records on a decentralized ledger, hackers would need to modify the whole chain to alter one record.


Smart contracts eliminate the need for middlemen to execute transactions, resulting in faster and less expensive transactions.
