What Are Smart Contracts on Blockchain?


Smart contract relevance has been growing exponentially from time to time. Many industries have proven the irreplaceable advantages that one can reap from the effectiveness and differences that smart contract development can make.


Smart contracts are defined.

The principle of smart contracts is often easier to understand than its definition. We could analogise it to purchasing an item from a vending machine. The buyers will insert the coins or other kinds of payments. Then they will press the button to pick the correct item.

The button activates the supply lever to bring out the items from the machine.

In this vending machine, there is no human-intermediary involved. The transaction occurred without a third party.

The analogy above could describe how smart contracts work and their central role. It removes the third party which governs the transactions. Without intermediaries, the buyer and seller can interact, which brings us to the definition of a smart contract.

A Smart Contract is a decentralised app that governs a transaction. Its role is more common in the business environment.

Depending on the design of the smart contract, its governance could result in the exchange of money, service delivery, ownership status, file transfer, and many other types of digital activities.

When used in different industries, the applications of innovative contract development will never be more straightforward. The developers would use the solution to match the clients’ requirements and needs.

Smart contracts do not have legal power unless the human parties have added legally binding agreements. Their primary role is to execute the business logic, which conducts different tasks as mentioned above.

How smart contracts work

Smart contracts simply work by using the framework of “if/when… then…”.

When the conditions are met, specificbut even the local trades are alsobusinesses tasks will be executed. All of the actions are pre-determined conditions.

For instance, if a best smart contract cryptocurrency  governs the release of funds, then there are some terms that need to be met first.

In a decentralized marketplace, the buyer and seller make transactions without the existence of a third party. Smart contracts replace this role.

The buyer will send the payment. Then the seller will send the item to the buyer.

If the buyer accepts the item, the funds will be immediately released to the seller when the buyer marks the order as finished.

But if the buyer doesn’t accept the item, the buyer could complain and ask for a refund. In this case, the funds will be returned to the buyer’s account.

There are more smart contract examples, such as asset registration, notifications, tickets issuing, delegations, and so on.

The blockchain will then be updated to mark the finish of the transaction. As we know, blockchain data is reversible. That means the transaction can not be changed or tampered with by third parties.

The clients and participants must decide how things work. In the same contract creation, developers will program it. The business teams will work together with the INC4 developers to state their requirements and needs in the smart contract developer.

Benefits of smart contracts

Here are the benefits of smart contracts that many businesses can reap:

The automation benefits

There is no such thing as manual transactions since all are governed by smart contracts already. If we have been living long enough to use the services where the middlemen are there, we’d notice the slow process. Sending money through a conventional bank could take days to weeks.

Smart contracts could take just a few minutes. They are automatic and programmable. Therefore, when the conditions are met, the tasks will be executed immediately. There is no long waiting time anymore.

Security perks

Security and privacy have been challenging tasks in traditional contracts. The involvement of the third parties which govern the transactions can be a double-edged sword. There are loopholes which irresponsible parties can use to tamper with transactions.

Meanwhile, smart contracts have layers of security which most outsiders won’t be able to penetrate. There is cryptography, public keys, as well as private keys when using smart contracts. Not to mention that the data is stored in a decentralized system which has millions of backups across the globe. When a hacker tampers with a single piece of data, the other devices will recover the data quickly. So, there is no way for them to beat the entire blocks of information.

Transparency of information

Remittance in the traditional contract requires more time to finish. It should come through the workflow, which could take forever. Transparent enough? Nope!

Most clients who have used centralized services are often oblivious to the activities behind them. The imperfect system has been dominating for years and many people have been done with it.

In smart contract crypto, the workflows are much simpler. Archiving and tracing are very easy since everything is there. As a client, you will also be able to look into your assets. All the involved parties can fully access the history. Paperless transactions have more trustworthy credibility and transparency of the information.

Cost saving

It is not a new thing anymore that we have spent a lot of money on administration and service fees, which we don’t necessarily need. In traditional contracts, business makers will hire middlemen to process all of the things. Since they “hire”, they need to pay the intermediaries.
