Ethereum News Today: Polygon Suffers Hour-Long Outage Weeks After Major Network Upgrade

Polygon, a leading Ethereum Layer 2 solution, experienced a one-hour network outage on Wednesday following the unexpected exit of a validator node, which triggered a bug in the Heimdall consensus layer [1]. The disruption occurred just weeks after Polygon executed one of its most technically complex hard forks on July 10, which upgraded Heimdall to CometBFT and Cosmos SDK v0.50 with the goal of improving finality times and scalability [1]. The foundation confirmed the incident was localized to the Heimdall system, which is responsible for validator operations and Ethereum mainchain connectivity, while the block-producing Bor layer continued functioning normally, ensuring that regular transactions were not interrupted [1].

The disruption was detected shortly before 10:00 am ET and resolved by 11:01 am ET. A temporary patch was implemented by developers to restore the network. Polygon emphasized that the PoS chain itself remained live throughout the outage, although users may have faced disruptions when accessing apps due to RPC issues. The foundation is now working with RPC providers to expedite the restoration of user-facing services [1]. The incident briefly affected Polymarket, the largest blockchain-based prediction market, which experienced error messages on its website during the outage [1].

This is not the first time Polygon has faced technical challenges. The platform has seen increasing competition in the Ethereum Layer 2 space, with over $1.1 billion in total value locked, but has been losing influence amid growing alternatives. The POL token declined slightly in the wake of the incident, trading at $0.22 with a 1% drop on the day according to The Block data [1]. The outage comes at a critical juncture as Polygon continues to scale and maintain its position among major Layer 2 platforms.

The incident underscores the inherent risks associated with complex network upgrades and highlights the need for improved post-upgrade monitoring and communication. While the hard fork aimed to enhance functionality and reduce finality times, the subsequent disruption raises questions about the robustness of the implementation and the readiness of the network to handle unexpected validator exits. Polygon’s ability to address the issue promptly and transparently will be key to maintaining user confidence and reinforcing its position as a reliable infrastructure provider in the Ethereum ecosystem [1].
