The Sui mainnet blockchain returned to operation Thursday after a software bug halted transactions for nearly six hours [1].
This outage disrupts the perceived stability of the network's infrastructure and impacts investor confidence in the blockchain's reliability during version updates.
The disruption was caused by a bug within the v1.72 network update [2]. Specifically, the error occurred in the gas-charging and transaction-scheduling logic, which caused the network to stall [2]. This technical failure prevented the processing of transactions across the global mainnet.
Reports on the exact duration of the outage vary. CoinTelegraph reported the network was offline for five hours and 55 minutes [1], while other reports cited a duration of nearly six hours [3]. However, Yahoo Finance reported a shorter two-hour outage [4].
Some reports suggest this event was not an isolated incident, noting it as the second straight day of outages for the network [5]. The restoration of services required a fix implemented by network validators to resolve the scheduling bug [3].
The technical failure had an immediate effect on the SUI token's market performance. The price of SUI dropped by 3.21% following the outage [6]. Market analysts noted a seven-day Relative Strength Index (RSI) of approximately 26.5 [7]. Some observers pointed to a support price level of $0.886 as the network attempted to recover [7].
Sui has not provided a formal statement regarding the long-term prevention of similar logic bugs in future updates.
“The Sui mainnet blockchain returned to operation Thursday after a software bug halted transactions for nearly six hours.”
The outage highlights the risks associated with rapid deployment of network updates in decentralized environments. When a core logic bug in gas-charging or scheduling occurs, it can freeze the entire mainnet, creating a single point of failure that contradicts the promise of high-availability blockchain infrastructure. The resulting price volatility demonstrates how technical instability directly translates into market risk for token holders.
