The Polygon Heimdall V2 mainnet, the consensus consumer for the Polygon proof-of-stake chain, went down on Wednesday as a consequence of a suspected “consensus bug,” the Polygon staff mentioned. The service has been since restored.
Heimdall V2, which handles communication between nodes validators on Polygon, went down about 9:30 UTC and didn’t impression the Bor layer, used for block manufacturing and transaction processing, in line with an update from Polygon.
The disruption lasted one hour and was brought on by an unidentified validator’s exit from the community, Polygon spokespersons informed Cointelegraph.
Block manufacturing on the Bor mainnet was uninterrupted all through the downtime, and any discrepancies between the community’s precise uptime and block explorers are actually being resolved. Polygon spokespeople mentioned:
Following Heimdall’s restoration, we noticed sync inconsistencies rising throughout a number of RPC suppliers’ Bor nodes. We are actually actively collaborating with all RPC companions to speed up decision and restore full availability. One supplier is already again on-line, with barely delayed sync.”
Constant community uptime is vital for blockchain networks that invoice themselves as a borderless various to conventional finance that’s out there 24 hours a day, year-round. Nevertheless, challenges to network uptime have grown as a consequence of growing community complexity.

Heimdall V2 improve goes stay
The Heimdall V2 upgrade was launched in early July, slashing finality occasions to about 5 seconds and upgrading the community’s tech stack, which now depends on CometBFT and Cosmos-SDK v0.50.
“That is essentially the most technically complicated exhausting fork Polygon proof-of-stake (PoS) has seen since its launch in 2020,” Polygon co-founder, Sandeep Nailwal, said in a July 8 X submit.
Whereas decreased block occasions and better community throughput proceed to be the main target of blockchain networks, the improved efficiency introduces complexity within the system and extra breaking factors.
Heimdall V1 was additionally a supply of community downtime points. In March 2022, Polygon skilled several hours of downtime as a consequence of an error within the Heimdall layer.
On the time, the Polygon staff said the Heimdall V1 challenge was the results of a software program bug that brought on validators to be on completely different variations of the blockchain.
