What Are Smart Contracts? The following is the explanation

What are Smart Contracts?

Smart contracts are sophisticated computer programs that are inherently tied to the terms of an agreement between a buyer and seller, which are directly encoded in lines of code. The program that encapsulates these agreements, is disseminated across decentralized blockchain networks such as Ethereum or Ontology . Once certain predefined conditions are met, the smart contract autonomously executes its programmed actions. Once executed, the code becomes immutable, virtually impervious to reversal or modification.

The emergence of smart contracts marks a paradigm shift in the execution of transactions and agreements and facilitates anonymous transactions between multiple parties that lack mutual trust, all without the intervention of a centralized authority or third-party oversight. 

Just as vending machines simplify the purchasing process by eliminating the need for direct interaction with a merchant, smart contracts operate in a similar way, offering automated transactions without requiring explicit trust in the counterparty. 

This capability has attracted significant interest from businesses seeking greater security against loss and increased customer confidence. As a result, many companies are integrating smart contracts into their operational framework to take advantage of the inherent advantages they offer in terms of efficiency and security.

How Smart Contracts Work

Smart contracts are executed on a blockchain network, where they are distributed across decentralized computer systems. Here's how it works.

• Creation: smart contracts are created by developers who write contract code, define the terms and conditions of the agreement. This code is then distributed to the blockchain network.
• Deployment on Blockchain: Once the code is ready, it is deployed into the blockchain, making it immutable and publicly accessible. This guarantees transparency and security, because the implementation of the contract cannot be changed by any party.
• Trigger Conditions: smart contracts contain instructions that are executed automatically when certain pre-defined conditions are met. These conditions can be anything from a specific date or time, to receipt of payment, or completion of a task.
• Execution: When the trigger condition is met, the smart contract executes the programmed instructions. This may involve transferring funds from one party to another, updating digital records, or triggering further actions in the contract.
• Verification: Once executed, the results of the smart contract action are verified and recorded on the blockchain. This ensures that all parties involved can verify the outcome of the contract and that it has been implemented correctly.
• Immutability: Once deployed on the blockchain, smart contracts are immutable, meaning they cannot be changed or tampered with. This ensures the integrity and trustworthiness of contract implementation.

Conclusion

Overall, smart contracts automate and simplify the execution of agreements, eliminating the need for intermediaries and providing a secure and transparent way to carry out transactions on a blockchain network.
