Smart Contracts and their features explained

Smart Contracts — the digital revolution in legal agreements. The term popularized by Ethereum founder, Vitalik Buterin, smart contracts are self-executing, programmable, and resistant to tampering.

Understanding Smart Contracts

Smart contracts are essentially programs that run specifically on a blockchain. They have rules and conditions encoded in them, which ensure the contract is automatically executed if met by involved parties.

Smart contracts differ from regular contract management – they’re used for automating transactions and facilitating direct agreements between users. For example, Ethereum allows developers to deploy their own smart contracts using its platform, and to run them, you can buy Ethereum coins (ETH). 

Per stats, “The smart contracts market revenue by the end of 2021 was US $150.2 Million. The smart contracts market is expected to reach US$ 1,515.4 Million by 2032, growing at a CAGR of 23.5% from 2022 to 2032”.

From banking to real estate, smart contracts have the potential to transform countless industries when integrated into their processes.

Key Features of Smart Contracts

In this section, let us explore the main features that make smart contracts stand out and why they hold such immense potential for widespread use.

Smart contracts can be used for managing and authorizing patient data access, orchestrating treatment plans, and streamlining medical billing processes. This can improve the overall efficiency and security of the healthcare system while ensuring patient privacy.

For example, a smart contract could be configured to grant access to a patient’s medical records only when specific conditions are met, such as the patient providing consent or the accessing party being a certified medical professional. This ensures the secure and controlled sharing of sensitive information.

Real Estate

Smart contracts can revolutionize the real estate industry by automating property transactions, lease agreements, and property registration. This can help eliminate fraud, streamline verification, and reduce the need for agents or brokers, making the entire process more efficient and affordable for all parties involved.

For example, a smart contract could be designed to automatically transfer property ownership once payment has been completed and all required documents have been submitted and verified. This would significantly speed up the buying and selling process, removing the need for costly intermediaries and paperwork.

Supply Chain Management

By leveraging smart contracts, supply chain relationships can be optimized, and the tracking of goods can be made more transparent and immutable. This not only improves trust among stakeholders but also helps with regulatory compliance, reduces counterfeits, and optimizes resource allocations.

For example, a smart contract could be implemented to enforce the payment of suppliers once the products have been received and validated, ensuring timely payment and fostering trust among supply chain partners.

Additionally, the contract can be programmed to update the product’s status when it undergoes specific checks throughout the supply chain, creating a transparent, verifiable audit trail and helping prevent counterfeit products.

Voting and Governance

The incorporation of smart contracts into voting systems can help ensure security, transparency, and verifiable results. Their use in governance will minimize tampering concerns, reduce administrative costs, and aid in the fair and efficient implementation of policies and regulations.

For example, a smart contract-based voting system could be designed to automatically tally votes and declare the results once the voting period has ended, ensuring a transparent and tamper-proof method of determining election outcomes.

Moreover, the system could securely store voters’ identities to prevent double-voting or fraud, saving resources on voter verification and monitoring.

Finance and Banking

Smart contracts can revolutionize the finance and banking industry by automating and streamlining various processes, such as loans, securities, and asset management. This can lead to faster transactions, reduced paperwork, increased security, and regulatory compliance, significantly enhancing the customer experience.

For example, a smart contract could be developed to automatically execute loan repayments based on predefined terms and schedules, ensuring accuracy and timeliness.

Smart contracts can facilitate faster and more secure financial transactions, including cross-border payments, securities trading, and lending. They can also be used for automated financial planning and smart investment solutions that leverage predefined logic and data-driven decision-making.

Intellectual Property Management

Artists, creators, and inventors can use smart contracts to protect their intellectual property, streamline royalty payments, and enforce licensing agreements. The transparency and immutability of blockchain technology will play a key role in preventing theft, assuring rightful ownership, and reducing IP conflicts.

For example, a smart contract could be designed to automatically distribute royalty payments to content creators every time their work is used or licensed, ensuring fair compensation and eliminating the need for manual calculations or third-party interventions.

Furthermore, the contract can also verify the authenticity of the work, confirming that the rightful owner is credited and protecting against unauthorized use or distribution.

IoT (Internet of Things)

Smart contracts can significantly enhance IoT operations by automating decision-making, data exchange, and asset management among connected devices. This can result in improved security, efficiency, and scalability for IoT networks, as well as enable innovative business models and value-added services.For example, a smart contract could be developed to coordinate and manage thousands of connected devices in a smart city, making decisions on data usage, device permissions, and energy consumption based on predefined conditions and real-time data. This would optimize resource allocation, ensure seamless connectivity between devices, and reduce energy consumption with a more eco-friendly approach.

Document workflow automation and Smart Contracts

Document workflow automation and smart contracts can work together to streamline and optimize business processes.

Smart contracts are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. These contracts can automate the process of verifying and enforcing the terms of an agreement, without the need for intermediaries such as lawyers or notaries.

Document workflow automation, on the other hand, is the process of automating the routing, approval, and storage of documents within an organization. This technology can help organizations to streamline their processes, reduce errors, and increase efficiency.
