The high-performance Layer-1 blockchain Sui Network has experienced a turbulent 48 hours, suffering consecutive network halts that sent its native token, SUI, into a steep downward spiral. The double-day disruption has reignited debates over the stability of modern high-throughput blockchains.

Anatomy of a Double Outage: What Went Wrong?
The technical issues began on Thursday when the mainnet stalled for over five hours. While validators quickly applied an interim patch to restore operations, the fix proved temporary. By Friday morning, the network stalled again, forcing the core development team to address a deeper architectural conflict.
According to the Sui Core Team, the root cause lies in the interaction between the newly deployed v1.72 release—which introduced Address Balances—and the network’s gas charging logic. The temporary patch deployed on Thursday carried a known, low-probability risk of triggering another halt, which materialized the following morning.
“While high-throughput Layer-1 networks promise unprecedented speed, the complexity of state-management updates like Address Balances often introduces unforeseen edge cases in gas calculation. This double halt underscores the delicate balance between rapid feature deployment and mainnet stability.”
Technical Resolution Details
The Sui development team confirmed that validators have now successfully deployed a permanent, long-term solution. This update fully resolves the conflict between the gas charging logic and the v1.72 release features. Transactions on the mainnet are currently flowing normally, with block production fully restored.
The “Solana-Killer” Curse
Sui, launched in 2023 by Mysten Labs after a massive $300 million Series B funding round, has frequently been labeled a “Solana-killer” due to its parallel transaction execution capabilities. However, like Solana, it has faced growing pains. This week’s incidents follow a similar six-hour outage in January, raising questions about the network’s readiness for enterprise-grade adoption.
Frequently Asked Questions
What caused the Sui network outage?
The halts were caused by a bug in the v1.72 release, specifically an incompatibility between the new Address Balances feature and the network’s gas charging logic.
Is the Sui network back online now?
Yes, validators have implemented a permanent fix, and the mainnet is operating normally with transactions processing as expected.
How did the SUI token react to the news?
The SUI token fell 20% over the week, trading around $0.89, which is approximately 83% below its January 2025 all-time high of $5.35.
