Smart contracts are nothing more than computer programs stored on a blockchain that execute when certain circumstances are satisfied. They are often used to automate the implementation of an agreement so that all parties can be certain of the conclusion instantly, without the involvement of an intermediary or time lost.
Additionally, they can automate a workflow by initiating the next action when certain circumstances are met.
The operation of smart contracts
Smart contracts operate by encoding simple “if/when…then…” expressions into code on a blockchain. When preset circumstances are satisfied and validated, the activities are carried out by a network of computers. These steps may include disbursing payments to designated parties, registering a vehicle, providing alerts, or issuing a ticket. When the transaction is complete, the blockchain is updated. This means that the transaction cannot be altered and that only parties granted authorization can view the outcomes.
Within a smart contract, as many stipulations as necessary can be included to ensure that the assignment is executed satisfactorily. To set the conditions, parties must agree on The representation of transactions and their data on the blockchain govern all smart contract transactions, on all conceivable exceptions, and on a framework for resolving disputes.
The smart contract can then be coded by a developer — however firms that use blockchain for business are increasingly providing templates, web interfaces, and other online tools to facilitate the construction of smart contracts.
The advantages of smart contracts
Rapidity, efficacy, and precision
When a condition is satisfied, the contract is immediately executed. Due to the fact that smart contracts are digital and automated, there is no paperwork to handle and no time wasted reconciling errors that frequently occur when documents are filled in manually.
Transparency and trust
Because no third party is involved and because participants exchange encrypted records of transactions, there is no reason to suspect that information has been altered for personal gain.
Security
Because blockchain transaction records are encrypted, they are extremely difficult to hack. Additionally, because each record on a distributed ledger is tied to the previous and subsequent entries, hackers would have to alter the entire chain in order to change a single record.
Savings
Smart contracts eliminate the need for middlemen to conduct transactions and, thus, the time delays and fees associated with them.
Smart contract applications in real life with examples
- Supply Chain Management
By boosting supply chain transparency, Sonoco and IBM are trying to eliminate bottlenecks in the transfer of life-saving drugs. Pharma Portal is a blockchain-based technology powered by IBM Blockchain Transparent Supply that follows temperature-controlled pharmaceuticals throughout the supply chain, providing trusted, dependable, and accurate data across different stakeholders
- Increasing retailer-supplier trust
The Home Depot employs blockchain-based smart contracts to handle vendor issues fast. They are strengthening connections with suppliers through real-time communication and better insight into the supply chain, which results in more time for vital work and innovation.
