Built to compete with other speedy layer-1 blockchains, the Sui network has once more suffered from the same ills that rival Solana once faced: downtime.
The “network stall,” first identified and investigated on Thursday morning, led to more than five hours of a major outage as the Sui team worked on a solution.
“Sui Mainnet is currently experiencing a network stall,” the blockchain posted on X around 10:30 a.m. ET. “Be aware that transactions may be paused at this time. Updates will be shared as soon as they are available.”
An update to the Sui network status page at 3:40 p.m. ET noted that a “fix is rolling out to validators.”
The latest stall comes just five months after a similar event affected the layer-1 mainnet in January for more than six hours. Prior to that, the network dealt with a significant validator issue in 2024 that prevented transactions from processing.
Amid the downtime, Sui’s native token SUI fell 5.4% in the last 24 hours to trade at $0.92, outpacing losses from Bitcoin, Ethereum, and other major cryptocurrencies.
The token reached an all-time high of $5.35 in January 2025 but has since fallen more than 82% from that point.
Earlier this year, the first SUI ETFs reached the market, with products from Canary and Grayscale offering exposure to the token and staking rewards to traditional investors. Launched in 2023, the Sui network was developed by Mysten Labs, a spinoff of Meta’s Diem project, which raised $300 million in a Series B round valuing the company at $2 billion in 2022.
