Zilliqa battles back-to-back network disruptions amid latest upgrade rollout

As a long-term crypto investor, I’ve seen my fair share of operational disruptions in various blockchain networks. However, the recent experience with Zilliqa has been particularly frustrating. I was initially concerned when I heard about the “temporary disruptions to block production on mainnet” on May 8. But I was reassured by the quick response from the Zilliqa team and their commitment to prevent further disruptions.


The Zilliqa network has encountered some disruptions in its recent operations, resulting in delays in block production on its mainnet. As of May 10, however, normal network functions have been reestablished. The reason behind these disruptions remains under investigation.

As a crypto investor, I’ve received an update from the Zilliqa team regarding the current status of their network. They’ve shared that following some “temporary hiccups in block production on the mainnet,” the network is now operational once again. The infrastructure team is currently working diligently to ensure the network’s stability and is actively “investigating the root cause of the recent disruptions.”

Zilliqa battles back-to-back network disruptions amid latest upgrade rollout

As a dedicated researcher studying the intricacies of the Zilliqa network, I’ve been closely monitoring its operations since the initial signs of disruption on May 8. This disruption was marked by a slowdown in block generation. In response, our technical team has been working around the clock for nearly 48 hours to prevent any further interruptions and ensure the smooth functioning of the network.

As a Zilliqa investor, I’d put it this way: Around 9:30 am UTC on May 9, while checking the network, I noticed an issue with the Zilliqa technical team discovering a malfunction. Instead of displaying the expected data from a node using RLP (Ropsten Lightweight Ethereum Client), they encountered a null value due to what seemed like an invalid database lookup.

The team has established private testing platforms where they can replicate the problem and experiment with potential bug solutions. These internal networks enable them to evaluate prospective resolutions in a controlled setting prior to implementing them on Testnet and eventually, the main network.

Around 2:30 pm UTC on May 9, the team successfully resolved the issue and brought back all functions with a fix. At the same time, they initiated the deployment of Zilliqa network upgrade version 9.3.4. This upgrade comes with several improvements to ensure better Ethereum Virtual Machine (EVM) compatibility. The team expressed their regret for any inconvenience inflicted on users and the entire Zilliqa community during this period.

Despite the recent fixes and upgrades, the Zilliqa mainnet experienced another disruptive incident on May 9 at approximately 7:05PM UTC. In response, the team intensified their debugging efforts to accurately identify the underlying cause and effectively resolve the issue.

Zilliqa’s block production has encountered disruptions caused by technical issues before. For instance, in December 2023, an incident occurred that significantly impacted block production, leading to a decrease of approximately 50% in daily transactions on the Zilliqa blockchain – from around 61,000 to 30,906.

The Zilliqa team is actively working to identify the source of the recent network interruptions and appreciates the community’s “understanding and cooperation” as they work towards a resolution.
