Smart contracts, the digital bridges facilitating decentralized applications, have recently become integral to blockchain technology. 

Like there are various forms of blockchain, smart contracts also have unique advantages and potential pitfalls.

Here, we’ll jump deep into the dynamic world of smart contracts, highlighting the top smart contract use cases in 2023. Join us to learn more.

What is a Smart Contract?

A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code.

These contracts are stored on a blockchain and automatically activate actions when predefined conditions are met, ensuring that the terms are executed as agreed upon without the need for intermediaries.

Smart contracts are like digital agreements that can’t be changed once set. They work like automatic rules that kick in when specific things happen. This makes tasks simpler, clearer, and safer for everyone involved.

According to Grand View Research, the Global Smart contract market has reached over $684 M by the end of 2022. And its end use is as diverse as ever. Check the figure below:

How do Smart Contracts Work?

So, you’re curious about how smart contracts work? Think of them as digital agreements running on code.

Here is a quick rundown of how they operate:

How-do-Smart-Contracts-Work

Step 1: Creation & Deployment

A smart contract begins its journey when a developer crafts it using specialized programming languages tailored for specific blockchain platforms, such as Solidity for Ethereum.

After the coding phase, this digital contract is dispatched and anchored onto the blockchain. This deployment ensures that the contract remains unalterable and its operations are transparent for all to see.

Step 2: Agreement & Validation

Before any magic happens, every party involved has to be on the same page. They showcase their agreement by employing their distinct cryptographic signatures.

This vital step is more than just a digital handshake; it ensures that every participant is fully aware of and consents to the intricacies and expected outcomes of the contract.

Step 3: Activation

With the signatures in place, the smart contract awakens and enters a vigilant mode. Much like a sentinel, it continually scans the blockchain or even gathers intel from external data providers, known as oracles.

Its sole mission during this phase is to ascertain if its coded conditions are fulfilled.

Step 4: Automatic Execution

When the smart contract discerns that its set triggers or conditions align with the current state, it leaps into action.

Programmed to operate autonomously, it undertakes tasks it was designed for, ranging from disbursing funds to amending digital ledgers.

Step 5: Blockchain Verification

The beauty of blockchain technology is its distributed consensus. As the smart contract performs its duties, numerous nodes within the blockchain network come together to validate the contract’s operations.

This collective agreement not only underscores the authenticity of the actions but also fortifies the process against any potential tampering.

Step 6: Contract Closure or Continuation

Once the smart contract has danced to its tune, it approaches a crossroads. If crafted for a singular transaction, it gracefully concludes its mission. However, if its purpose was to handle recurring or multiple transactions, it gears up for another round, perpetually ready to serve its coded directives.

The beauty of smart contracts lies in their trustless nature; parties don’t need to trust each other but can instead trust the code.

Benefits of Smart Contracts

Smart contracts, merged with blockchain technology, are revolutionizing the digital transaction landscape.

Here are the top 5 benefits of smart contracts.

1. Security

One of the most celebrated benefits of smart contracts is their heightened security. Embedded within the blockchain, they inherit the cryptographic security of the entire network. 

Any attempt to alter a smart contract post-deployment is noticeable and highly resistant to tampering. This ironclad security ensures that once terms are agreed upon, they cannot be changed without the consensus of all involved parties.

2. Transparency

Transparency is paramount in digital transactions, and smart contracts excel in this domain. Every detail of the contract, from its inception to its execution, is recorded on the blockchain and is accessible for verification.

This open-book nature ensures that all participants can audit the contract’s operations, fostering a transparent environment where each action is accountable.

3. Cost Savings

Smart contracts eliminate the need for intermediaries, like brokers or notaries, in the transaction process. Automating complex procedures and bypassing third-party involvement significantly reduce associated costs.

This organizes financial transactions and results in substantial cost savings for all parties involved.

4. Trust

Trust is a cornerstone in any agreement, and smart contracts are engineered to cultivate it. Since they’re self-executing and operate based on predefined rules, there’s minimal room for bias or manipulation. 

The decentralized validation process of the blockchain ensures that no single entity has overarching control, fostering an environment of mutual trust among participants.

5. Efficiency

Time is of the essence in the digital age, and smart contracts are efficiency champions. By automating tasks and eliminating the need for manual oversight or third-party verification, they expedite processes at an unprecedented pace.

Whether settling trades, processing claims, or any other transaction, smart contracts ensure swift and smooth operations, driving productivity to new heights. 

Because of these benefits, the U.S. Market CAGR, 2023 -2030 is expected to be 81.9%. See the figure below for more details.
