A faulty interaction between a new address-balance feature and Sui's existing gas and consensus logic caused three mainnet outages within 48 hours, according to a post-mortem published Sunday by the Sui Foundation. The bug was introduced in the v1.72 release and repeatedly triggered network halts before developers identified the root cause. The post-mortem details how the newly shipped feature conflicted with core protocol mechanics, cascading into full network stalls each time. Sui, a layer-1 blockchain backed by Mysten Labs, has positioned itself as a high-performance network suited for gaming and consumer applications, making the repeated downtime a reputational concern. Developers have since patched the issue, though the three halts in quick succession raise questions about upgrade testing and deployment safeguards on the network.
