LLTS74 — What Are Smart Contracts and How Do They Work?

Smart Contracts are an essential part of a Blockchain, read this article to find out what they are and how do they function.

Blockchain technology is still relatively young, even after ten years. The popularity of blockchain has grown due to its extensive adoption in several sectors. The distributed digital ledger technology’s foundation offers several benefits by keeping track of every transaction involving data or money. Let’s examine smart contracts in more detail, as they are an essential element of blockchain technology.

What Are Smart Contracts

Smart contracts are computer programs or protocols that automatically execute transactions stored on a blockchain when certain conditions are satisfied. In other words, smart contracts automate the execution of contracts so that all parties can be aware of the outcome as soon as is practical, without a go-between or a lag time. In self-executing contracts, known as smart contracts, the terms of the buyer-seller agreement are directly included in the program’s code. According to American computer scientist Nick Szabo, who created the digital currency “Bit Gold” in 1998, smart contracts are computerized transaction protocols that carry out contract terms. When used, it renders transactions transparent, traceable, and irreversible.

Blockchain-based smart contracts are becoming increasingly common, especially in industries like insurance, finance, government, and others with comparable needs. Over the next five years, it is anticipated that this rise will be enormous as numerous industries use smart contracts’ many advantages, including their accuracy and transparency, to operate more effectively.

How Do Smart Contracts Work?

Consider digital “if-then” statements made by two (or more) parties to be smart contracts. The agreement may be honored, and the contract is said to be finished if the expectations of one group are met.

The same principles that govern other blockchain transactions apply to smart contracts. The following activities need to be taken:

1. A user starts a transaction from their blockchain wallet.

2. The distributed database receives the transaction, which is then checked for identity.

3. The transaction, which may involve a transfer of funds, is authorized.

4. The code identifies the kind of transaction to be conducted contained in the transaction.

5. A block containing the transactions is uploaded to the blockchain.

6. Any modification to the contract status is updated.

Benefits Of a Smart Contract

1. Smart contracts provide the parties concerned various benefits, including:

2. Independence: By making the agreements directly, the parties cut out the middleman.

3. Reliability: The contract is held securely on a distributed network and is very difficult to alter or forge.

4. Security: The contract cannot be lost because it is disseminated and replicated on all network nodes.

5. Cost savings: All parties save money by doing away with intermediaries and commissions.

6. Accuracy: This type of contract eliminates the possibility of inaccurate terms or processes.

7. Sustainability: Contracts reduce paper consumption in offices, notaries, and registries, which reduces pollution.

The Bottom-Line

Many developers, researchers, lawyers, and even doctors are interested in smart contracts.

Smart contracts are still in their early stages, though. Users of smart contracts do not have to trust intermediaries. Still, they have to believe that the code was written correctly, which is difficult given the present level of security. Numerous bug vulnerabilities have been found over the years, enabling dishonest actors to steal customer money. Hopefully, these problems will lessen in frequency as the code develops.
