Sui Network (SUI), a relatively new blockchain, experienced an unexpected two-hour outage on Thursday.
Sui's downtime was caused by a bug in its transaction scheduling logic, which led to its validator network crashing. The issue has now been resolved, the network said.
Several exchanges, including Upbit, had temporarily suspended SUI transactions. Blockchain outages can take place for a plethora of reasons, ranging from a 51% attack to technical errors. A common errors is that of nodes - or individual entities that process transactions - being unable to sync with each other, causing the blockchain to go offline.
Software bugs may be another error vector, where outdated code can render the network's processes inoperable.
SUI tokens came back up after falling nearly 7%.
