The Polygon Foundation has announced the successful completion of a hard fork to resolve a bug that was causing delays in transaction finality on its PoS network. The issue led to a 10–15 minute lag in “local fast finality” or “milestones,” which are essential for validator synchronization and transaction confirmations.
To fix the problem, the Polygon team rolled out new versions for both its block production layer (Bor) and its consensus layer (Heimdall). While the network continued to produce blocks during the incident, the delay created uncertainty and caused the network’s native token, POL, to briefly drop in value before recovering.
The hard fork is part of Polygon’s ongoing efforts to improve network reliability and address technical issues. The problem, which stemmed from an anomaly within its validator network, was quickly addressed by the Polygon Foundation with a fix rolled out to validators.
While the incident caused concern among users and developers who rely on fast confirmations, no financial losses or data corruption were reported, and the security of the underlying Ethereum base layer remained uncompromised.
The disruption has been characterized as an operational hiccup rather than a systemic threat, with the foundation praised for its transparent and swift response. The network is now back to normal performance, and the event has highlighted the importance of strong redundancy and real-time monitoring for L2 ecosystems.
