Sui Blockchain Faces Another Outage as Transaction Processing Stops

Sui Network Faces Second Outage in 2026

The Sui blockchain, developed by Mysten Labs, has encountered a mainnet outage that has temporarily stopped transaction processing. The team is currently addressing the issue, which marks the second outage for the network this year.

In a statement on X, the Sui Core team confirmed that the network is experiencing a stall and is actively working to resolve the problem. They noted that transactions are currently paused and promised to provide updates as they become available.

This outage adds to a series of technical difficulties that Sui has faced since late 2024, including previous outages and performance issues. The specifics of the current disruption have not yet been disclosed.

Since its launch in 2023, Sui has aimed to compete with established blockchains like Ethereum and Solana by offering fast transaction speeds and low fees. However, the recent outage may raise concerns among traders and developers who rely on the network for decentralized finance and gaming applications.

In the wake of this incident, the native token, SUI, has seen an 8% decline in value over the past 24 hours, reflecting the mixed conditions in the broader cryptocurrency market. The Sui team has committed to keeping the community updated as they investigate the outage further.
