The Zilliqa infrastructure team continues to work diligently to resolve the recent disruption to the mainnet block generation. Their preliminary analysis indicates that the issue may stem from a specific function returning a null value instead of a node’s RLP due to a potential invalid database lookup. This misbehavior results in an error being thrown, disrupting the network.
To tackle the issue head-on, the team has established internal rehearsal networks that aim to replicate the mainnet disruption. These isolated environments are designed to recreate the problem and trial potential bug fixes safely. Testing within this controlled setting ensures that proposed solutions undergo thorough evaluation before deployment to the Testnet and, eventually, the mainnet. The Zilliqa team is yet to share further updates and detailed steps for remediation as more information becomes available.Â
Initial Slowdown and Response
Approximately 20 hours prior, a slowdown in mainnet block generation was detected around 03:12 PM UTC. To diagnose further, the network’s transaction processing was halted at 04:00 PM UTC, giving the network time to clear the transactions in the mempool and self-recover. After a 30-minute pause, normal operation resumed.
The team awaited a new epoch to achieve full data synchronization before re-enabling transactions, which was expected within 20 minutes. During this time, they monitored the continued functionality of block generation to ensure stability. The team remains committed to identifying the root cause of the disruption and keeping the community informed with regular updates.
