After final week’s major six-hour outage, the Sui community has applied upgrades to its mainnet, deploying model V1.63.3, and upgrading the protocol to model 107.
The Sui Network rolled out protocol upgrades that reportedly handle the underlying points which will have triggered the outage Cryptopolitan reported final week, which lasted about 6 hours and stalled about $1 billion in transactions.
Upgrades to Sui’s protocol and mainnet enhancements
The upgrades primarily embody fixes to validator consensus points that prevented nodes from reaching settlement on rejected transactions, optimized transaction affirmation paths for higher effectivity and reliability, making certain the power to realize finality instantly and disabling RPC interfaces utilized by validators for transaction signing and submitting aggregated validator signature transactions.
The undertaking’s staff has additionally made plans for quicker detection/restoration mechanisms, higher tooling for its operators, and expanded testing of the consensus engine. The staff’s focus will stay on enhancing resilience whereas preserving Sui’s strengths.
What occurred to the Sui Network?
The Sui Network suffered a major outage on January 14, which halted transactions and froze over $1 billion in worth on the community.
The Sui Basis acknowledged the issue at 3:24 pm UTC on X amid reassurances to the customers that core builders had been working on a repair.
“The Sui community is now again and absolutely operational. Transactions are flowing usually. If you happen to proceed to expertise points, please refresh your app or browser window. Thanks to your endurance,” the Basis wrote on X, promising a full incident report within the days that adopted.
The staff began trying into the issue about half-hour earlier than they made the announcement, in accordance with the Basis. Nevertheless, the community was not restored for almost 6 hours afterward.
The incident was reportedly brought on by what the staff known as a consensus outage, which is a technical challenge that prevented the blockchain from confirming transactions.
It’s the community’s second major outage since its origin
The outage from final week was the second major one the Sui community has confronted because it began working in Might 2023. The primary actual one occurred in November 2024 and was linked to challenges that had accrued over time.
The post-mortem the staff later shared recognized the basis trigger as an inner divergence in validator consensus processing, which they are saying was triggered by an edge-case bug within the consensus commit logic.
Notably, it was not brought on by an exploit, community congestion, or timing synchronization points, and there was no rollback, nor had been person funds misplaced within the means of fixing the difficulty, because of the community’s security mechanism, which labored because it was designed.
It isn’t the primary high-speed blockchain to face these struggles. Networks like Solana have confronted comparable points up to now, although Solana has since left these behind and has not had any outages in a couple of yr. That is thanks partly to emergency updates which have allowed validators to speak extra successfully and handle essential points quickly.
