Introduction to Polygon’s Hard Fork
Polygon has executed a hard fork to resolve a software bug that caused up to 15-minute transaction finality delays on its proof-of-stake network. The issue first appeared on September 10 and was identified as a bug in Polygon’s node software that impacted validator synchronization.
Cause of the Disruption
The bug caused delays in reaching “local fast finality,” a milestone system that is essential for network transaction confirmation. Ethereum checkpointing and block production were unaffected, but users experienced significant delays. A few third-party services were also interrupted by the bug, including some decentralized finance apps that reported brief accessibility problems.
Impact on Services
The primary block explorer, Polygonscan, ceased displaying updates for over five hours due to the bug. Despite the slowdown, Polygon stressed that no funds were at risk and Ethereum’s underlying security guarantees remained unaffected. This reassurance was crucial in maintaining user trust and preventing potential panic.
Resolution through Hard Fork
To address the problem, developers prepared two critical updates, including Bor v2.2.11-beta2, covering the block production layer, and Heimdall v0.3.1, which required a hard fork to restore consensus and state synchronization. The fork was executed on September 10 at 3 p.m. UTC, bringing milestones and checkpointing back to normal operation.
Post-Upgrade Stability
Following the upgrade, Polygon confirmed that consensus finalization was fully operational, with the team monitoring the network closely to ensure stability. The native token of the ecosystem, POL, experienced a 4% decline during the disruption but quickly rebounded. This rapid recovery is a positive sign for the ecosystem’s resilience.
Continuous Development
This is the second major technical issue Polygon has encountered in 2025. When a validator exit compelled RPC node resynchronization in July, the Heimdall component momentarily stopped finality. Polygon co-founder Sandeep Nailwal has since reiterated that network upgrades remain central to the project’s push toward what he describes as “GigaGas throughput,” targeting long-term scalability comparable to global payment systems.
Ecosystem Growth and Adoption
Polygon has cemented its place in Web3 infrastructure despite recent setbacks. The network facilitates billions of foreign exchange transactions and is a leader in stablecoin and real-world asset adoption. The blockchain also hosts the recently uploaded GDP data from the U.S. Department of Commerce, demonstrating its capability to handle complex and sensitive data.
Conclusion
Polygon’s hard fork has successfully resolved the software bug, restoring normal operation to the network. As the ecosystem continues to grow and develop, it is likely that we will see further upgrades and improvements.
