Sui mainnet is back online and transactions are flowing normally.
The end of epoch halt was triggered during the rollout of yesterday's long-term fix. As validators restarted to deploy the new binary, the randomness initialization that runs at the start of each epoch was unable to complete because it has a higher quorum threshold than Sui consensus. A latent bug in how that failure state is preserved across validator restarts then prevented the network from completing its transition to the next epoch.
Validators have implemented a fix that addresses both the underlying bug and the affected epoch, and network activity has resumed.
A more detailed incident review is forthcoming.
Sui mainnet stopped accepting user transactions due to an issue during the epoch change beginning at ~1:30PT. Validators are up and creating system transactions, but user transactions are not currently being accepted. The Sui Core Team is investigating, and updates will be shared as soon as available.
Activity on Sui mainnet has resumed, and transactions are flowing normally.
Both today’s and yesterday’s halts are due to the interaction of the 1.72 release, which introduced Address Balances, and gas charging logic. Yesterday’s implemented fix was an interim measure designed to restore functionality to the network while the Sui Core Team worked on a long-term solution.
The interim fix had a known issue with a low probability of causing a halt. This morning, the network hit a variant of the known issue and halted.
As of now, the long-term solution has been implemented by validators, fully addressing known issues caused by the original bug, and network activity has resumed.
A more detailed incident review is forthcoming. Thank you for your patience.
@daveontheway As a SUI elitist I’ll go with Gmonad, since it has more exponential growth potential than SUI, but SUI does have more utility for devs in my humble opinions
