Sui's mainnet experienced a network outage on Thursday, temporarily halting on-chain transaction processing. The project team stated on the X platform that the core team has begun fixing the issue, but as of press time, the specific cause of the outage has not been explained.

The project team stated that repairs are underway.

The official statement says the mainnet is currently experiencing a "network stall," meaning user-submitted transactions may be temporarily unable to be processed. This anomaly has temporarily slowed down network activity, essentially halting transaction processing.

The project team stated that it will continue to disclose the progress of the investigation and repair, but has not yet given a timetable for recovery, nor explained which part of the process triggered the failure.

This is the second time the system has crashed this year.

This is Sui's second network outage this year. The report mentions that since the end of 2024, the public blockchain has experienced multiple performance degradations or service interruptions, and its stability remains a major concern.

Developed by Mysten Labs and launched in 2023, Sui is a next-generation Layer 1 public chain that emphasizes high throughput and low transaction fees. For networks like this that market themselves on high performance, a mainnet outage would directly impact the operation of applications such as DeFi and games.

SUI fell 8% in 24 hours.

Following the news of the outage, Sui's native token, SUI, fell 8% in the past 24 hours. The report also noted that while the overall trend in the crypto market is currently diverging, the stability of public blockchains remains a key indicator for traders and developers.

Blockchain network outages have always been a sensitive issue in the market, especially given the intensifying competition in Layer 1. Any shutdown could affect developer deployments, user activity, and on-chain fund retention.
