Polygon Restores Consensus After RPC Node Bug Disruption
The Polygon Foundation announced that normal operations have resumed on their layer-2 Ethereum scaling network after resolving a consensus issue caused by a software bug. This bug impacted some Remote Procedure Call (RPC) nodes, which are crucial for relaying data between blockchain applications and the network.
What Caused the Disruption?
According to Polygon co-founder Sandeep Nailwal, the software bug was triggered by a faulty proposal from a network validator. This led to certain Bor nodes, responsible for transaction processing and block production, diverging onto separate forks of the network. Despite the disruption, on-chain block production remained uninterrupted.
RPC nodes are fundamental in facilitating communication between blockchain layers and applications. As blockchain protocols and functionalities evolve with features such as smart contracts and cross-chain interoperability, the risk of bugs causing partial outages increases. Recent incidents highlight the necessity for robust development and maintenance.
Polygon’s Response and Resolution
To address the issue, the Polygon team promptly executed a hard fork. This fix reestablished synchronization between the impacted nodes and the blockchain network. The foundation emphasized that block production continued normally, ensuring that no major interruptions occurred for end-users.
This isn’t the first time the network faced such issues. In July, a similar event occurred due to an exiting validator on the Hemidall mainnet, disrupting node synchronization for about an hour. Despite this, block production was unaffected, with Bor running as expected.
The Importance of Network Resilience
This incident underscores blockchain networks’ growing pains, especially as they seek to scale up and accommodate diverse functionalities. With innovations like stablecoins and cross-chain interoperability launching on Polygon, the network continues striving to solidify its reliability and user trust.
