What Is a Smart Contract: Key Points in Brief
Smart contracts are a central feature of blockchain technology and are now indispensable. They are a form of digital contract on the blockchain.
Smart contracts use the blockchain as well as cryptocurrency. The blockchain must be compatible with smart contracts. The two best-known blockchains for use with smart contracts are Ethereum and Binance Smart Chain.

What Is a Smart Contract?
A smart contract is a self-executing contract in which the terms of the agreement are directly written into lines of code. These contracts exist on a blockchain—a decentralized and distributed digital ledger that records transactions. The main advantage of smart contracts is that they allow trusted transactions and agreements between various, often anonymous parties without the need for a central authority, a legal system, or an external enforcement mechanism.
What Is a Smart Contract and How Does It Work?
To understand how a smart contract works, you can think of it like a vending machine. Imagine inserting a coin into a machine to buy a drink. The machine automatically performs a series of actions as soon as the coin is inserted: it checks the amount, selects the drink, and dispenses it—all without any human intervention. A smart contract works in much the same way:
Input of Conditions: The contract terms are entered into the blockchain as code. These terms are “if-then” statements that determine which actions should be carried out.
Verification: The blockchain verifies the conditions. Once the requirements are met, the contract is triggered.
Execution: The contract executes automatically. The actions specified in the code occur without delay and without the possibility of manipulation.
Advantages of Smart Contracts
Smart contracts offer a range of benefits that make them especially attractive for various applications:
Automation and Efficiency: Because smart contracts execute automatically once the conditions are met, manual processes and delays are eliminated. This leads to a significant increase in efficiency.
Security and Trust: Smart contracts run on a blockchain that is cryptographically secured and difficult to hack, making them extremely safe. Since they are immutable, the parties can be sure that the contract terms are upheld.
Transparency: All parties to a smart contract have access to the contract’s terms and execution, increasing transparency.
Cost Reduction: Because no intermediaries such as lawyers or notaries are required, transaction costs can be significantly reduced.
Areas of Application for Smart Contracts
Smart contracts can be deployed in a variety of industries and applications. Here are some of the most notable:
Smart Contracts in Financial Services
In the financial sector, smart contracts can be used to process transactions, manage derivatives, and carry out securities trading. They enable secure and rapid transactions without the need for banks or brokers as middlemen.
Programming Smart Contracts for the Real Estate Sector
Smart contracts can streamline buying and selling property. They can be used to automate title transfers and verify compliance with payment terms, reducing the need for notaries and lawyers.
Smart Contracts on the Blockchain in Supply Chain Management
In the supply chain sector, smart contracts can help track goods from production to the consumer. They can ensure that all participants meet the contract terms and that products are delivered on time and in perfect condition.
Smart Contracts in Healthcare Are Indispensable
Smart contracts can be used in the healthcare sector to securely manage patient data and control access to it among various parties. For instance, they could automate the billing process between health insurers and medical service providers.
Use Cases for Smart Contracts: Insurance
In the insurance industry, smart contracts can be used to automatically process claims. When certain conditions are met—such as the occurrence of a specific event—the smart contract can automatically initiate a payout.
Smart Contracts: Challenges and Risks
Despite their many advantages, smart contracts are not without challenges and risks:
Complexity of the Code: Because smart contracts are based on code, programming errors can cause major problems. Bugs in the code may mean the contract does not execute as intended or that security vulnerabilities arise.
Legal Uncertainty: Because smart contracts are a relatively new concept, many countries lack clear legal frameworks for their use. This can lead to legal uncertainties.
Immutability: While the immutability of the blockchain is an advantage in terms of security and trust, it also means that errors in the smart contract cannot simply be corrected.
