Sui mainnet hit another outage Thursday, grinding transactions to a halt and prompting a fresh round of scrutiny over the layer-1’s reliability.
Mysten Labs’ team acknowledged the disruption on X, saying the “Sui Mainnet is currently experiencing a network stall. The Sui Core team is actively working on a solution. Be aware that transactions may be paused at this time. Updates will be shared as soon as they are available.” At the time of the announcement the project had not disclosed a cause.
Why it matters
- This is the latest in a string of performance problems for Sui, which has weathered previous slowdowns and outages — including one earlier this year. Recurring interruptions are especially concerning for networks that pitch themselves as high-performance infrastructure for DeFi and blockchain gaming.
- Sui launched in 2023 and is positioned among newer layer-1s that compete with Ethereum and Solana by promising high throughput and low fees. Reliability questions could temper adoption momentum.
Market impact
- The SUI token fell roughly 8% over the past 24 hours amid the outage; broader crypto markets were mixed.
What to watch
- The Sui core team says it will provide updates as its investigation continues. Traders, developers and projects running on Sui will be watching for root-cause details, estimated recovery time and any remediation or hard-fork plans.
