Existing State of Security for Smart Contracts
Smart contracts are one of the vital components of the blockchain landscape. They help in automation of complex financial transactions and workflows for exchanging information without the involvement of intermediaries. Blockchain technology has formidable potential for introducing fundamental changes in the approaches to conducting business.
However, some of the high-profile smart contract security breaches have led to significant financial losses and damage to reputation of projects. Before you find the answers to “How does AI improve smart contracts security?” you should know about the notable security concerns that affect smart contracts. Some of the prominent security issues for smart contracts include errors in code, malicious inputs, and insecure third-party integrations.
The first notable attack on smart contracts was the DAO hack in 2016, which led to a loss of over $50 million. Developers had to implement a hard fork of the Ethereum blockchain to restore the missing funds. In July 2017, the Parity wallet breach resulted in theft of over $30 million. The primary reason behind the Parity wallet breach was the vulnerability in a smart contract library.
The necessity of AI-powered smart contracts for improving security can also point to the smart contract exploits on Binance Smart Chain in 2021. Another notable platform that suffered the brunt of smart contract security breaches is KingDice. Hackers leveraged a flaw in the network’s smart contracts to steal almost $300,000 in August 2017.
Such types of incidents emphasize the need for ensuring security of smart contracts and monitoring smart contracts for security against common attacks and vulnerabilities. On the other hand, it is difficult to ensure security of smart contracts without the prominent challenges. Why do you need AI smart contracts to ensure better security? The complexity of the process for analyzing and verification presents a major challenge, even with the comprehensive verification and code review process.
On top of it, the lack of uniformity in the smart contract development environments can create complications in ensuring safety. Therefore, AI and ML have emerged as major tools for addressing the challenges in detection of smart contract security issues. Artificial intelligence and machine learning can support the proactive detection of anomalies and potential risks in smart contracts, thereby improving their overall security.
