Sui mainnet experienced an approximately 6-hour outage on January 14. According to the event review released by the Sui Foundation, the root cause of this failure was an internal disagreement among validators during consensus processing, which led to new checkpoints being unable to be properly certified, and subsequently, transaction submissions also experienced timeouts.

It is worth noting that this was not caused by network congestion or a surge in transaction volume leading to a shutdown, but rather a consensus mechanism issue at the validator level. The foundation also explicitly stated that user funds and account statuses remained completely secure, and there were no instances of certification state forks or transaction rollbacks during this period. This means that although the network was temporarily unable to process new transactions, historical data and user assets were not at any risk.

Validators fighting is a thing, but at least the funds are safe, which is better than anything else. --- 6 hours? I thought it was another big event, but it turns out there was just a consensus issue. --- Basically, it's still a misalignment on the validator side. As long as asset security is maintained, everything else is acceptable. --- Is it not congestion but the collapse of the consensus layer? Such failures are actually more heartbreaking. --- Sui is down again, when will it stabilize, brothers? --- The security of user assets is very critical. No forks mean the main network is stable, which is a good sign. --- It was caused by internal disagreements among validators, feeling like family members arguing and shutting the door.

Validators passing the buck to each other, so we have to shut down. That logic is really something. The consensus mechanism throwing a tantrum is indeed a bit hard to handle, but at least the funds are safe. 6 hours again, another thrilling "exercise." Validators fighting among themselves, and we’re the ones paying the price. I’m really familiar with this combo. Mindset may collapse, but at least I didn’t lose money, so I’ll keep buying the dip. Another incident, when will Sui finally settle down? Consensus issues are more troublesome than network congestion, feels like not the main point. Fund safety is the last stubbornness. Checkpoint authentication sounds really ridiculous. This is a common problem with big projects, causing trouble every now and then.

Validators fighting causing network downtime, I didn't see this plot coming haha 6 hours, luckily assets are fine, otherwise the mentality would really explode Sui's architecture design is still a bit fragile, is the consensus layer so prone to issues? So basically, it's just that the validator nodes are not aligned, and the checkpoint got stuck Fortunately, there was no rollback, otherwise that would have been a real disaster Will there be an enhancement to the synchronization mechanism among validators after this incident? Network interruption ≠ funds are at risk, the foundation explained this clearly Validators fighting caused a bug, will we learn a lesson next time? Consensus issues sound more unsettling than congestion issues, that's my intuition The 6-hour "service suspension" is still a bit damaging to on-chain activities

Validators are fighting, and we're affected... but at least the funds are safe. Let's just consider it a maintenance pause. Validator consensus issues? That’s quite a mess. Luckily, there was no rollback. Six hours of downtime sounds easy to say, but all my pending orders were left waiting in vain. As long as the assets are intact, that's fine... but I feel a bit uneasy. Consensus disagreement? It seems Sui still needs to optimize its mechanism. Fortunately, there was no trade rollback, or it would have caused a real uproar. Validators are "playing mahjong," so let's just wait and see.
