Web3.0 Frontier: New Challenges and Responses to Blockchain Security

Against the backdrop of rapid development in the Web3.0 space, blockchain security has become a focal point in the industry. This article delves into the security threats faced by the blockchain ecosystem and their defense strategies, focusing on efforts to enhance the security of blockchain and smart contracts through advanced technologies.

The recently released "Hack3d: Q1 2025 Security Report" reveals new trends in digital asset theft and security threats. In Q1 2025, losses from on-chain fraud incidents amounted to approximately $1.66 billion, representing a significant increase of 303% compared to the previous quarter. Among these, a certain exchange suffered a hacker attack, resulting in losses of about $1.4 billion, making it the largest single incident of the quarter. Ethereum remains the primary target for hacker attacks, with just three security incidents leading to asset losses of $1.54 billion. More concerning is that the recovery rate of stolen assets is only 0.38%.

In the face of increasingly complex attack methods, the blockchain security industry is actively responding. The application of innovative technologies such as Zero-Knowledge Proofs (ZKP) and Multi-Party Computation (MPC) provides new possibilities for addressing the increasingly severe security issues. These technologies can not only protect user privacy but also achieve transaction auditability, attack traceability, and asset recovery.

For blockchain developers and project teams, security experts advise treating security as a core principle, integrating it into every stage of development. This "security-first" strategy is crucial for building trustworthy Web3.0 applications. At the same time, seeking comprehensive and impartial third-party audits from professional security organizations can provide an independent perspective to identify potential risks.

Artificial intelligence plays a dual role in blockchain security. On the one hand, AI is used to analyze vulnerabilities and potential security flaws in smart contracts, improving audit efficiency. On the other hand, attackers may also leverage AI to enhance their attack methods, which means that the bar for security countermeasures has been raised, and the industry needs to invest in stronger security solutions.

Formal verification technology, as a method that proves computer programs run as expected through mathematical means, plays an important role in smart contract auditing. It complements manual auditing, together enhancing the overall security of smart contracts.

As traditional financial institutions enter the Blockchain space, the types and complexities of security threats are also changing. Simple attacks targeting individual users or small projects have evolved into complex attacks aimed at enterprise-level applications. This evolution involves not only the growth of project asset scales but also the special security requirements of enterprise-level applications, regulatory demands, and the challenges brought by the deep integration of Blockchain with the traditional financial system.

In the face of these new security challenges, the industry needs to continuously innovate and improve security strategies to ensure the healthy development of the Web3.0 ecosystem. Only through continuous technological innovation and multi-party collaboration can a more secure and trustworthy blockchain world be built for users.
