The Sui mainnet halted operations on Friday for approximately 3.5 hours, leading to a complete stop in block production and transaction processing. According to reports, the outage was triggered by a software bug identified within the version 1.72 upgrade. This incident marks the second significant disruption for the network in just two days, raising questions about its technical reliability.
This latest downtime follows a previous six-hour outage, intensifying concerns over the stability of Ethereum-competitors during critical software rollouts. In contrast, rival networks such as Solana and Aptos maintained relative uptime during this window, per market data. Analysts suggest that recurring technical failures in Layer-1 blockchains often undermine developer confidence and long-term ecosystem growth.
