Smart Contract

« Back to Glossary Database

Smart contracts are self-executing contracts with the terms of the agreement directly written into lines of code. They automatically enforce and execute the terms of a contract when predetermined conditions are met, operating on blockchain technology to ensure transparency and security.

Evolution and Historical Context

The concept of smart contracts was first proposed by Nick Szabo in 1994, long before the advent of blockchain technology. Szabo, a legal scholar and cryptographer, envisioned a digital protocol that would facilitate, verify, or enforce the negotiation or performance of a contract. However, it wasn’t until the emergence of blockchain technology and the creation of Ethereum in 2015 that smart contracts became a practical reality. Ethereum’s platform features a Turing-complete language that allows for the creation of complex contracts that can perform a variety of functions without human intervention.

Use Cases Across Industries

Smart contracts are now integral to several sectors, demonstrating versatility across various applications. In finance, they are used to automate payments, thus reducing the need for intermediaries and lowering transaction costs. For example, decentralized finance (DeFi) platforms utilize smart contracts for functions like loans and interest accrual, without the need for traditional banking structures. In supply chain management, smart contracts offer transparent tracking of products from origin to consumer, ensuring compliance and quality control. The insurance industry benefits from smart contracts in claims processing, where automated verification of claims can lead to faster payouts and fraud reduction.

Impact on the Market and Investment Landscape

The introduction of smart contracts has significantly disrupted traditional business models and investment strategies. By eliminating intermediaries, smart contracts reduce transaction times and costs, thereby increasing efficiency and profitability. The automation and immutable record-keeping inherent in smart contracts also enhance security and trust in transactions, which is particularly crucial in financial markets. Furthermore, the rise of smart contracts has spurred the growth of blockchain technology investments and the proliferation of new cryptocurrencies and tokens, each designed to leverage this technology in unique ways.

Current Trends and Future Outlook

The future of smart contracts is closely tied to the evolution of blockchain technology. With advancements in blockchain scalability and interoperability, smart contracts are becoming more efficient and can interact seamlessly across different blockchain networks. Additionally, the development of more user-friendly smart contract development tools is lowering the barrier to entry, allowing non-technical users to deploy smart contracts. There is also a growing trend towards integrating artificial intelligence with smart contracts to enable more complex decision-making processes, further expanding their potential applications.

Smart Contracts on MEXC Platform

On platforms like MEXC, smart contracts play a crucial role in enhancing trading functionalities and security. MEXC utilizes smart contracts for various purposes, including the execution of trades, management of liquidity pools, and implementation of user agreements. This integration ensures that all transactions on the platform are transparent, secure, and in compliance with the agreed-upon rules, providing a reliable and efficient trading environment for users.

Conclusion

Smart contracts represent a foundational technology that is reshaping the digital landscape. By automating and securing transactions across various sectors, they offer a robust solution that enhances efficiency, reduces costs, and builds trust. The practical relevance of smart contracts is most evident in areas requiring high levels of trust and transparency, such as finance, supply chains, and legal agreements. As blockchain technology continues to evolve, the scope and impact of smart contracts are expected to expand, further integrating into mainstream business practices and everyday transactions.

What is a smart contract?

A smart contract is a contract that runs on the blockchain network. The contract is executed by computers distributed globally. The process by which a computer executes a contract is what we often call “mining”. 

Characteristics ofEthereum Smart Contract

What is a smart contract?

Decentralization: Decentralization means that the same smart contract is kept by all running nodes. For simplicity, you can understand a node as a computer running the Ethereum network. Since every computer running a node has a backup of all contracts and they are distributed all over the world, it can be guaranteed that smart contracts will not be lost.

Consistency: Consistency means that the execution outcome for the same smart contract will be the same, even if they are executed by different nodes.

Automation: The smart contract can be executed like an automatic program, but it will remain dormant when the smart contract is not triggered.

Non-tampering: Once the smart contract is deployed on the blockchain, it cannot be changed, so we can say that the smart contract provides a tamper-proof program.

Customization: Before deployment, smart contracts can be coded in many different ways, so they can be used to create different programs – commonly known as DApp.

Application

Smart contracts have been implemented in various blockchain networks, among which the most famous and popular blockchain networks are still Bitcoin and Ethereum. Although the Bitcoin network is known for its digital currency, its protocols can also be used to create smart contracts. Bitcoin actually provides a programming language that allows developers to create custom smart contracts freely. Smart contracts can be applied in different scenarios, such as online elections, cross-border trade, payment channels, etc.

Pros

Automatic execution: The processes specified in the contract, including custody, maintenance, triggering, and settlement, can be automatically executed by nodes. Once the contract is completed and updated on the blockchain, it will be executed in strict accordance with the code without the need for human intervention.

Reliability: Smart contracts are more reliable as compared to a centralized intermediary due to their decentralized property. Since there is no middleman, the contracts can not be tampered with or lost. There is no server downtime problem in the blockchain network as it is run independently by nodes distributed all over the world. Since smart contracts are replicated by distributed nodes around the world, they are naturally tamper-proof and safe.

Efficiency: Compared with digital agreements executed through third parties, smart contracts are extremely efficient. Participating parties to the contract need not manually enter data and wait for the other party to process, and there is no need for an intermediary to process the transaction. Smart contracts can eliminate human errors and disputes between counterparties, thus speeding up the execution of the contract.

Cons

Issue of public trust when writing smart contracts: Bugs may appear in the formulation of codes. The key to the development of the current blockchain is to conduct independent third-party code verification and testing. However, it is difficult for third parties on the general chain to provide this service, and the establishment of a credible production mechanism is another key to development. Generally speaking, a fair “lawyer” is needed on the blockchain network to verify smart contracts to protect the interests of all participants.

The problem of smart contract intelligence: At present, it is still based on a simple contract or a fixed contract template. The technology research in language, writing, deployment, auditing, automatic auxiliary tools, artificial intelligence technology will present us with new models in the future,

Legality issue: Smart contracts have yet to gain recognition from the judicial body in most countries. If smart contracts involve physical goods, disputes may arise. The conduct of judicial arbitration is still unknown for the current development in blockchain technology.

Performance problem: Since smart contracts need to be broadcast on all nodes to ensure consistency, this process greatly reduces the efficiency of code execution, thereby slowing down the transaction speed. 

Summary

Novice users can understand smart contracts as code that can be executed automatically according to the terms of the contract. Once the smart contract is confirmed and deployed by stakeholders, it cannot be changed. The current common application of smart contracts is to carry out on-chain transfer transactions and DeFi applications.
