Sui network stall halts block production, token down 8%

The Sui blockchain experienced a significant network stall on Thursday, halting block production and pausing transactions for several hours. The incident triggered an immediate drop in the value of its native SUI token, which fell roughly 8% as the disruption unfolded.

The core development team confirmed the mainnet was experiencing a network stall and stated engineers were actively working on a solution. According to the blockchain's status page, the issue was identified and a fix was being implemented. Block explorers showed no new checkpoints or blocks being produced for an extended period, halting transaction finality across decentralized applications. The team assured users that funds remained safe during the pause.

This marks the latest in a series of technical disruptions for the Sui network since its mainnet launch in 2023. It is at least the third notable outage in approximately 18 months, following a two-hour disruption in November 2024 and a six-hour consensus outage in January of this year. In the January incident, officials traced the cause to an edge-case bug in validator consensus logic that prevented the certification of new transaction checkpoints.
