The Sui Network, a Layer 1 blockchain developed by Mysten Labs, is experiencing a network outage on Thursday after the project said its mainnet had “stalled,” temporarily halting transaction processing.
“Sui Mainnet is currently experiencing network stagnation. The Sui Core team is actively working on a fix,” the project posted on X. “Please note that transactions may be paused at this time. Updates will be shared as soon as they are available.”
The outage appeared to halt activity on the network, although the team had not yet revealed the cause of the issue at the time of publication.
The incident marks another in a series of technical disruptions for Sui. The blockchain has previously faced periods of degraded performance and outages, including one earlier this year.
Sui, which launched in 2023, is among a group of newer Layer 1 blockchains that compete with Ethereum and Solana by offering high-speed transactions and low fees. The network’s native SUI token is down 8% in the past 24 hours, although broader crypto market conditions were mixed.
Blockchain outages continue to be a widely watched issue for merchants and developers, particularly for networks that are marketed as high-performance infrastructure for decentralized finance and gaming applications.
Sui’s team said it would provide additional updates as the investigation continues.
