A smart contract is a self-executing computer program. Developing such a program requires not only tools — development environments — but also knowledge of programming languages, as well as the skills of analyzing the domain and building algorithms.
Choosing the right platform for a smart contract
When it comes to creating your own smart contract, the very first step is to choose a suitable platform for its development. Currently, the most popular platform for this purpose is Ethereum, thanks to its flexibility and the use of Solidity as the programming language. However, there are also other platforms such as NEO, EOS, Tron, and others that can be used for the same purpose.
The process of creating a smart contract
1. Analyzing
Before developing a contract, one needs to come up with a thought-through algorithm. The analysis skills are very important because building the sequence of checks that make up a smart contract is the most important part of the process. Any failure to include an essential check will result in losses for both counterparties. During the analysis process, it is necessary to define the contract terms, performance methods, and other parameters that will be included in the smart contract code.
2. Writing a code
Once the platform is selected, the developers need to write a code, using a specialized programming language such as Solidity for Ethereum or similar languages for other platforms.
3. Testing and debugging
After writing the code, it is necessary to test the contract for errors and fix any bugs that have been discovered. Specialized tools and development environments are used to thoroughly test the contract in different scenarios.
4. Deployment of the smart contract
After successful testing and debugging, the smart contract is ready to be deployed on the chosen blockchain platform. This requires determining the contract address which will be available for use by other participants in the blockchain network.
Use cases for smart contracts
Smart contracts in finance
In the financial industry, smart contracts are used to automate and simplify a variety of transactions, including money transfers, loans, insurance, and securities trading. For example, smart contracts can be used to automatically fulfill the terms of a loan agreement, pay insurance claims when a particular event occurs, or conduct secure and transparent trading operations on financial markets. This simplifies processes and reduces the risk of error and fraud.
Smart contracts in real estate
In real estate, smart contracts can be used to automate the process of buying, selling, and leasing real estate. For example, a smart contract can contain the terms of the transaction, such as the purchase amount, timeframes, and the terms of the transfer of ownership, and automatically fulfill those terms once signed by the parties. This can simplify and speed up the process of real estate transactions, as well as provide transparency and security for all the parties involved.
Smart contracts in supply chains
In supply chains, smart contracts can be used to automate ordering, payment, delivery, and inventory management processes. For example, a smart contract can include the conditions for the delivery of goods, payment to the supplier, and quality inspection of the delivered products. This can improve the transparency and efficiency of the supply chain and reduce the risk of disputes between parties. Moreover, smart contracts can help trace the origin of goods and ensure that quality and safety standards are met.
