Sui Blockchain Suffers Major 'Network Stall' for Over 5 Hours
Sui's layer-1 blockchain experienced a major network stall on Thursday, with transactions paused for over five hours. The issue, identified by engineers, is being addressed with a fix rolling out to validators. This is the second such outage in 2025, following a six-hour stall in January and a prior validator issue in 2024. Built to compete with speedy blockchains like Solana, Sui has faced similar downtime challenges. The SUI token fell 5.4% to $0.92, though it had reached an all-time high of $5.35 in January 2025. Launched in 2023 by Mysten Labs (a Meta Diem spinoff), the network raised $300 million in a Series B round valuing it at $2 billion in 2022. Recent SUI ETFs from Canary and Grayscale offered traditional investors exposure to the token and staking rewards.
