Sui, a decentralized layer-1 blockchain, faced a major hiccup on Nov. 21, halting block production for over an hour. The last block was recorded at 9:15 am UTC, with no new blocks since, as per SuiVision data. This downtime has sparked reactions, especially given Sui's ambitions to rival Solana. Crypto YouTuber Ajay Kashyap highlighted the irony, noting Sui's "Solana Killer" claims. The outage affected Sui's native cryptocurrency, which dropped nearly 11%. Exchanges like Upbit have paused SUI transactions, and the Sui Foundation has yet to comment on the issue.
