With this Blockchain technology, it is comfortable to build applications where one to more additional parties can reserve transactions instantly without any need for a central authority to confirm that trades are confirmed.
A Complete Guide to Understand Smart Contracts
Smart contracts can be considered prominent in blockchain technology . In the 1990s the smart contract was presented as a digital trade agreement that runs the legitimate terms of an agreement. These agreements will run automatically when certain conditions are met. In another word, we can say that smart contracts run the agreement execution without any enrolment of 3rd party, and by saving time so that all participants that are enrolled in the smart contract will take the result as soon as possible.
- Smart contracts are self-evident programs in which the transaction data is written directly into lines of code.
- According to the American computer scientist "Nick Szabo", who invented a digital currency called "Bit Gold" in 1998, Smart contracts are automated trade protocols that perform the execution of the program with the help of these transactions, which are transparent and are irreversible.
- Smart contracts permit the creators to make comprehensive decentralized apps and tokens. the uses of these in everywhere from the economy to the organization and are stored on the top of a blockchain like another crypto transaction. Once a smart contract app has been added to the blockchain it can be inverted and switched(although there are some anomalies).
The entire life cycle of smart contracts consists of four consecutive phases as illustrated in:-
1. Invention of smart contracts : Many involved parties preferably deal with the obligations, privileges, and prohibitions on contracts. After numerous contests conferences and negotiations, the contract can reach. Advisers or attorneys enable participants to formulate the first agreement. Developers then convert this agreement written in genuine languages into a smart contract written in computer languages including declarative languages and logic-based rule languages.
2. Deployment of smart contracts. The authorized smart contracts can then be established on a blockchain platform. Smart contracts that are stored on the blockchain network can not be changeable because they are fixed on the blockchain. Any modification needs the development of a new contract. Once a smart contract is established on the blockchain all the involved peers are able to approach the agreement with the help of the blockchain. Besides, In smart contracts, all peers' virtual properties are locked via freezing the corresponding digital wallets. For example, the coin transfers (either incoming or outgoing) on the wallets appropriate to the consensus are blocked. Meanwhile, the peers that are present in smart contracts can be recognized by their digital wallets.
3. Execution of smart contracts:- Contractual provisions have been examined and assessed following the use of smart contracts. when the contractual provision matches the contractual conditions will be automatically executed. It is the capital of knowing that a smart contract contains many declarative statements with coherent conditions. when a condition is activated the respective statement automatically runs. Accordingly, through the help of the miners, the transaction executes and validates on the blockchain The committed transactions and the updated states have been stored on the blockchains thereafter.
4. Completion of smart contracts:- After the execution of the smart contract, the new form of all peers is updated. As the result, the transaction is stored on the blockchain during the execution of smart contracts as well as updated states. Consequently, the virtual property has been shifted from one party to another(digital currency transfer from buyer to supplier).
Consequently, the digital assets of the involved parties have been unlocked. Therefore, the digital inheritance of involved peers has been barred. The smart contract then exhausted the entire life cycle.
Smart contract advantages
There are several potential business advantages of using smart contracts.
Cost efficiency. Smart contracts pledge to automate industrialization that spans the regulatory edge. This can reduce costs associated with running the business and free up resources like the staff required to keep an eye on a complicated process that responds to external factors affecting several organizations.
Processing speed. Smart contracts can improve the processing speed of business processes that run across multiple enterprises.
Autonomy. Smart contracts are run automatically when the conditions match there is no requirement for 3rd party to manage trades between enterprises.
Reliability. Smart contracts can also take advantage of blockchain ledgers and other distributed ledger technologies to maintain a verifiable record of all activity related to the execution of complex processes that cannot be changed after the fact. It also supports automated transactions that remove the potential for human error and ensure accuracy in executing the contracts.
