  • Sui blockchain halted block production for over an hour due to a reported DOS bug.
  • SUI token’s value dropped 11% during the downtime but recovered after the issue was resolved.
  • The Sui Foundation confirmed a fix and resumed network operations with support from validators.

Sui, a decentralized layer-1 blockchain designed for smart contract deployment, halted block production for more than an hour on November 21. Data from SuiVision, a blockchain explorer, showed the network stopped processing transactions at 9:15 am UTC.

Impact on SUI Token and Exchange Operations

The outage caused the SUI token’s price to dip nearly 11% during the disruption, trading at around $3.40, according to CoinGecko. Major exchanges, including South Korea’s Upbit, paused SUI deposits and withdrawals due to network instability.

The Sui Foundation acknowledged the issue two hours after the downtime began, stating they had identified the cause and were working on a solution.

Cause and Resolution of the Outage

Web3 security firm ExVul reported that the outage was likely caused by a denial-of-service (DOS) bug stemming from an integer overflow issue in the transaction scheduling logic. The foundation confirmed this assessment, crediting its community of validators for their swift assistance in resolving the problem.

After approximately two hours, the network resumed normal operations, with the SUI token rebounding to $3.60.

This marks the first major outage on the mainnet for Sui, which had experienced similar issues during its testnet phase. Industry experts noted that while outages are disruptive, they are not uncommon in blockchain systems and highlight areas for improvement.
