Challenges of Blockchain Faith: Reflections Triggered by the Sui Network Incident

Recently, a significant event in the Sui public chain ecosystem has sparked widespread discussion within the industry. On May 22, 2025, the largest decentralized exchange on the network was attacked by hackers, resulting in losses exceeding $220 million. This event not only exposed technical vulnerabilities but also triggered a profound reflection on the fundamental principles of Blockchain.

After the incident, the Sui network took a series of unconventional measures. First, the validating nodes quickly blacklisted the hacker’s address, freezing approximately $162 million in funds. Subsequently, the network decided to upgrade the protocol to transfer the stolen funds through a governance vote. Although this approach mitigated losses in the short term, it also raised questions about the irreversibility of Blockchain.

The approach of the Sui network is very different from the traditional way of handling security incidents in blockchain. In the past, events like Ethereum’s hard fork after The DAO incident or Bitcoin’s consensus rule upgrade to fix the value overflow vulnerability handled issues through forks, allowing users to choose which version to follow. In contrast, Sui’s method resembles a “protocol correction,” making modifications directly on the existing chain.

This practice has triggered a series of profound reflections: When a network can break the rules for “justice,” does it mean that it can arbitrarily change the rules in other situations as well? Is the blockchain adage “Not your keys, not your coins” still applicable on the Sui network? If this practice sets a precedent, will it be abused in the future?

From a broader perspective, this event also reflects an important issue facing the Blockchain industry: how to address real-world regulatory requirements and security challenges while maintaining decentralization and immutability. Consortium chains once enjoyed great popularity precisely because they met regulatory demands. However, over time, purely regulatory tools can no longer satisfy the needs of real users.

The fundamental value of Blockchain lies in its immutability and decentralization characteristics. Even in the face of immense pressure, adhering to these principles is what truly makes Blockchain attractive. The future of a network depends not only on its technical architecture but also on the beliefs and principles it upholds.

In today’s environment of increasing regulatory pressure, how to find a balance between compliance and innovation, and how to protect user interests while maintaining the core values of Blockchain, are all questions that the entire industry needs to think deeply about. On the path of future development, we need more wisdom and courage to face these challenges and uphold the unique value of Blockchain, rather than simply compromising towards centralization.
