Core Tech Updates

The Zilliqa mainnet is at present chugging alongside on the brand new model 5.1.1. In our earlier weblog publish, we went into element on the event and roll-out of model 5.1.0, with emphasis on the soundness and efficiency enhancements round good contract processing. Among the many different enhancements not talked about was a loosening of our blacklisting coverage to permit nodes that go offline to rejoin the community extra rapidly. Shortly after upgrading the mainnet to model 5.1.0, nevertheless, we seen a major delay in transaction affirmation throughout some epochs. Finally we realized the blacklist coverage change had launched a regression to our consensus protocol, thus we rapidly rolled out model 5.1.1 to disable the coverage change for now.

Past resolving that concern, the core group is now busy engaged on the developments for the following model. Whereas the work to allow quicker node rejoining continues, there are additionally enhancements within the pipeline round transaction monitoring and blockchain knowledge fetching. For instance, a transaction can get caught within the transaction pool for causes similar to a better than anticipated nonce worth. Within the current model, this info shouldn’t be uncovered to our API, which makes it more durable to diagnose on the consumer degree. We’re engaged on making this info accessible to customers quickly, so keep tuned as we begin to present extra particulars within the coming tech updates.
