The Polygon Foundation restored consensus and finality functions after a software bug caused some nodes to fall out of sync with the blockchain. A hard fork was successfully executed to fix the bug that disrupted RPC nodes used for relaying information between applications and the blockchain layer.

The bug was triggered by a “faulty” proposal from a validator, leading some Bor nodes onto divergent network forks. Fixes were rolled out to Heimdall v0.3.1 and Bor 2.2.11 beta2 to resolve the issue. Software bugs continue to pose challenges in blockchain networks, affecting user experience.

Despite the software bug on Wednesday, block production on Polygon was not halted. Node communication was impacted, causing a discrepancy between block production and node relay. This incident marks the second software bug experienced by Polygon since July, with similar issues affecting network communication.

In July, the Hemidall mainnet for Polygon’s PoS consensus mechanism was temporarily halted due to a similar issue. Block production continued via the Bor mainnet during the outage. The partial consensus layer outage was attributed to a validator exiting the network, requiring RPC nodes to resynchronize with the blockchain for normal functionality.

Polygon has faced challenges with software bugs impacting node communication, but block production has remained unaffected. The network has continued to add new blocks despite these issues, showcasing resilience in the face of technical challenges.
