🚨 Sui Admits a Single Transaction Could Bring Down the Entire Network After Three Outages in Less Than 48 Hours Sui Mainnet has come under intense scrutiny after suffering three major network interruptions between May 28 and May 29, 2026, raising fresh concerns about the reliability of one of the fastest Layer 1 blockchains in the industry. According to the official postmortem, the incidents were caused by bugs introduced in the v1.72 upgrade. The issues were linked to changes in the network’s gas charging logic and a newly implemented feature called “Address Balances,” designed to improve fee calculations. The most alarming finding was that a single malformed transaction could trigger validator crashes across the network, halting block production and checkpoint processing entirely. The first outage occurred on May 28 and lasted nearly six hours. After a temporary fix was deployed, two additional interruptions followed on May 29—one tied to another variation of the gas charging bug and another related to randomness state handling during epoch transitions. In total, the blockchain experienced more than 14 hours of downtime or degraded performance within a span of less than two days. The Sui team emphasized that the incidents were not the result of a hack or external attack. User funds remained safe, and no previously confirmed transactions were reversed. Nevertheless, the market reacted sharply. During the outages, SUI fell roughly 8.4%, while leveraged traders faced significant liquidations across multiple platforms. In response, developers announced stronger testing procedures, enhanced upgrade validation processes, and additional automated tools to identify critical bugs before future releases. Mysten Labs’ CEO also issued a public apology, describing the outages as unacceptable. The incident serves as a reminder that even the most advanced high-performance blockchains continue to face major challenges when balancing scalability, speed, and network resilience. ⚠️ Disclaimer: This content is for informational purposes only and should not be considered financial, legal, or investment advice.
