Polygon has resolved a software bug that affected some remote procedure call (RPC) nodes, leading them to fall out of sync with the blockchain. The issue did not halt on-chain block production. The Polygon Foundation confirmed that both consensus and finality functions have been restored following a hard fork that targeted the disrupted nodes. According to co-founder Sandeep Nailwal, the bug originated from a problematic proposal by a validator, which caused some Bor nodes to branch off onto divergent forks. The fixes were implemented in Heimdall v0.3.1 and Bor 2.2.11 beta2, which cleared the identified milestone from the database, allowing affected nodes to sync correctly and checkpoints to finalize normally. The incident is a reminder that as blockchain technologies grow more complex, bugs can occur more frequently. Previous similar issues in July also led to RPC node synchronization problems, but block production continued uninterrupted. The Polygon network remains operational, with proper transaction displays on its block explorer.
