What are Smart Contracts in Blockchain

In 1994, visionary cryptographer and legal scholar Nick Szabo envisioned a future where contracts weren’t just written on paper—they were encoded in digital form. Fast forward to today, and the Smart Contracts market is projected to soar to £294 million by 2026, highlighting their increasing influence and significance. Unlike traditional agreements, Smart Contracts are embedded in Blockchain technology, executing actions automatically once specific conditions are met, often within a set timeframe.

What are Smart Contracts in Blockchain?

Smart Contracts are based on 'if/when then' statements embedded directly in Blockchain code. They automatically execute predefined commands and actions once specific conditions are met and verified. These actions can involve a range of tasks, from releasing funds to the correct recipients to sending notifications or registering a vehicle.

They are simple programs stored on the Blockchain network that become operational only when predetermined conditions are met. Typically, they can seamlessly automate the way agreements are executed. These ensure that the terms and conditions agreed upon by the parties are fulfilled.

Moreover, Smart Contracts eliminate the need for any third party to interfere in the agreement, fostering a high level of transparency between the parties. This transparency is a key feature that enhances the trustworthiness of the agreement's terms.

Smart Contracts are self-executing programs that automatically perform the actions stated in the contract or agreement between parties. Once the contract conditions are achieved, the transactions made between the parties are irreversible but trackable. However, the degree of reversibility might depend on the Blockchain platform used. No central authority, legal system, or external enforcement bodies can interfere because such contracts are self-executing and rigid.
 

How do Smart Contracts work? 

The workings of Smart Contracts on a Blockchain can be understood through a few key principles:

a) Coded Logic and Agreement Terms: Smart Contracts contain coded logic that dictates the terms of an agreement. They activate when specific conditions are met, automatically executing the agreed-upon actions without manual intervention.

b) Time Constraints: Smart Contracts can include time constraints, triggering actions if conditions aren’t met within a set timeframe. This feature ensures agreements are honoured promptly and reliably.

c) Unique Address Assignment: Each Smart Contract is assigned a unique address on the Blockchain, allowing it to be accessed and linked by other users or contracts. This address is essential for seamless interaction within the Blockchain ecosystem.

d) Illustrative Example: For example, "If you send object X, you receive a set amount of cryptocurrency." While the logic is simple, implementing Smart Contracts often requires technical expertise to ensure they function securely and correctly within the Blockchain.

Use Cases of Smart Contracts

Contracts are now being executed autonomously, without intermediaries. This development is bringing the framework into reality. The following are a few examples of Smart Contracts in Blockchain.

1) Improving Customer Experience

Smart Contracts can enhance business-to-customer relationships effectively. For example, a fitness clothing brand is partnered with an online music streaming app, where the person works out while listening to music. Based on their activity, the person will be receiving offers for new clothes and subscriptions to music.

2) Entertainment Consumption

In the entertainment sector, Blockchain can enhance the consumer connection in entertainment consumption with the chosen sections. For example, Non-fungible Tokens (NFTs) are validated with virtual assets possession. The buying, selling or transferring of the NFTs (non-fungible tokens) can be integrated by Smart Contract.

3) Healthcare Communication

Proper communication is required among the patients and insurance providers. Storing the patients’ data on the Blockchain will reduce the paperwork and healthcare providers will be able to send data directly to the providers. For example, If the patient requires medical interventions, requests through Smart Contracts will check the insurance coverage and release payment instantly.

4) Supply Chain Management

Enterprising Blockchain in Supply Chain Management will enhance the functions in  a few specific areas. The goods and materials could be easily tracked by the Smart Contract. For example, while going through the international supply chain and calculating the product taxes, most of the Blockchain software will be able to track the product’s origin.  However, some companies or organisations can explore Smart Contracts on Blockchain to reduce errors and improve efficiency.

5) Human Resource Management

With the distributed ledger technology, the functions of the human resource manager can be automated. For example, while onboarding new employees to the organisation, Smart Contract can easily authenticate the employees’ details and impose duties and responsibilities.

Benefits of Smart Contracts

Crypto contracts offer a range of advantages that aid in streamlining transactions and enhancing security. Here are the benefits of Crypto contracts listed below:

a) Reliable: These contracts are executed as soon as the pre-determined conditions are met. This means that the outcomes are immediate. Moreover, as the contracts are digital and automated, no paperwork is required. This will save considerable time that could have been spent correcting errors while documenting them manually. 

b) Reduced Chances of Manipulation: Smart Contracts assure data persistence and reduce the possibility of manipulation. Thus, the candidates will be able to receive exact details simultaneously.

c) Environment-friendly: A key advantage of such Blockchain-based contracts is that they eliminate the need for paperwork in offices, notaries, and other similar places. This way, they can contribute to making the world safer and more sustainable.

d) Safe and Secure: This is another aspect that makes the Crypto contracts advantageous. Since they are stored on the Blockchain, they are secure, and no one can tamper or alter them. Furthermore, all Blockchain transactions are recorded and encrypted, making them highly safe and secure.

Limitations of Smart Contracts

Blockchain contracts have certain limitations that make it challenging for the parties involved. These limitations are described below:

a) Third-Party Involvement: These Smart Contracts do not eliminate the involvement of third parties. They remain involved with Blockchain contracts in some other capacity. For instance, lawyers will not be required to prepare individual contracts. However, they will become associated with such contracts as developers will consult them to understand the contract's terms better to create better and more effective codes.  

b) Handling Ambiguity: Another major limitation of such Blockchain-based contracts is their inability to handle terms and conditions. These need to be more specific and clearer. However, it is only sometimes possible that all the terms and conditions are clear to all the parties. Consequently, numerous times, Blockchain contracts have not been highly effective or useful.
