Foreign media, citing Sandmark's analysis, reported that Sui experienced three network outages within a 36-hour period from May 28th to 29th. While no user funds were lost, users were temporarily unable to transfer funds, adjust positions, or use on-chain applications, which has once again drawn market attention to the stability shortcomings of high-performance public blockchains.

Three shutdowns within 36 hours

The article points out that Sui has recently garnered attention for its performance, as it is designed to process large volumes of transactions in parallel to support everyday applications such as payments, gaming, and financial instruments. Therefore, network availability is no longer just a user experience issue, but a question of whether the infrastructure can support real-world business operations.

Sandmark believes all three outages are related to a recent software update. The first two outages stemmed from a flaw in the network's processing of some payment transactions, causing system crashes. The team subsequently implemented fixes, but these did not cover a similar issue, leading to another network outage. The third outage was caused by a separate vulnerability, occurring during a routine system switchover.

• The downtime is concentrated on May 28th and 29th.
• There were three interruptions within 36 hours.
• The triggering causes are all related to software defects.

The fact that the funds were not lost does not mean the impact was limited.

The article states that while Sui's outage did not result in direct loss of on-chain assets, this is only the most basic consequence. For users, being offline means that although assets are still in their accounts, they cannot be accessed in a timely manner, nor can they log into applications to complete transactions or manage positions.

Such disruptions have a particularly significant impact on payments, derivatives, and other high-frequency scenarios. If public blockchains aspire to handle a wider range of financial activities, throughput and speed alone are insufficient; continuous and stable operation is also a prerequisite.

Reputation repair will take time

The article mentions that Sui's token performance strengthened in early May due to increased on-chain staking, and it launched a platform for prediction markets and derivatives trading on the testnet. The subsequent system outages at the end of the month create a stark contrast to this period's growth narrative.

Foreign media outlets believe that other mainstream public blockchains have also experienced similar failures. While some projects subsequently recovered and resumed growth, rebuilding network trust often takes much longer. For the crypto industry, this incident once again demonstrates that if blockchain is to become a serious financial infrastructure, reliability must be on par with performance.
