The Sui blockchain experienced a network stall on Thursday, halting block production for nearly two hours. The outage was confirmed by the Sui team on X, stating that "the Sui Core team is actively working on a solution" and that transactions may be paused.
According to block explorer SuiScan, no new blocks were produced since the stall began. The network's status page noted at 07:36 PDT that the issue had been identified and a fix was being implemented. This marks the third significant outage for Sui, following incidents in November 2024 and January 2026, making it the second such stall within five months.
Sui is a Layer 1 network developed by Mysten Labs, a team originally from Meta's canceled Diem project. The team assured that user funds are likely unaffected.
