SUI Network Faces Another Major Network Issue in 2026
This was the second major disruption on the SUI network in this year, 2026. The first outage took place earlier this year in January, which lasted for more than 6 hours.
According to the reports circulated on social media, users have been facing this problem for more than two hours now, sparking fear in the SUI community. There has been more than two hours where no new blocks were produced for more than two hours.
At present, Decentralized applications and other services on the blockchain, including blockchain explorers like SuiScan, are also facing slow performance. Some of these protocols have temporarily halted their operations on the network.
Sui is a Layer 1 blockchain that was developed by Mysten Labs using a programming language called Move. This blockchain is developed to execute a large number of transactions at once by using a parallel execution technique. For this, it also uses an object-based data model.
However, there are many blockchains like Solana that have faced congestion-related issues. Sui has also faced many problems related to how its validators reach agreement or how transactions are scheduled.
At the time of writing this, SUI is trading at around $0.929 after dropping around 5% on a daily chart with a market capitalization of around $3.72 billion, according to CoinMarketCap.
