- The Sui mainnet experienced its second outage in a week.
- It is related to a bug in the gas calculation logic in a recent software update to version 1.72.
On Friday, the Sui layer-one blockchain experienced another outage, causing a network freeze that temporarily halted block generation and transaction processing. Although the network resumed operation six hours later, the outage raised serious concerns among experts, as it was the second outage in the past two days.
Редакция Happy Coin News ReportedOn Thursday, May 28, Sui experienced an outage that brought the entire ecosystem to a halt while the Sui Core team and validators worked to fix the problem. Users were unable to make transactions until service was restored. And then another outage occurred literally the next day.
Both today’s and yesterday’s network outages were caused by the release of update 1.72, which added address balances and gas calculation logic. Yesterday’s fix was a temporary measure designed to restore network functionality, the Sui team commented on both events.
The two-day network outage was caused by a critical bug in the gas calculation logic introduced in software version 1.72. The system issue led to validator failures when certain transactions hit the vulnerable section of code, breaking consensus and halting block generation. A similar issue was previously observed in early 2026.
The latest incident has demonstrated that the industry still faces the challenge of scaling while maintaining uninterrupted operations. This is especially true for Sui, which attracts users with zero fees for transactions with seven popular stablecoins.
