The Polygon Heimdall V2 mainnet, the consensus consumer for the Polygon proof-of-stake chain, went down on Wednesday attributable to a suspected “consensus bug,” the Polygon workforce stated. 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 replace 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 at the moment are being resolved. Polygon spokespeople stated:
Following Heimdall’s restoration, we noticed sync inconsistencies rising throughout a number of RPC suppliers’ Bor nodes. We at the moment are 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 essential 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 community uptime have grown attributable to growing community complexity.

Heimdall V2 improve goes reside
The Heimdall V2 improve was launched in early July, slashing finality instances to about 5 seconds and upgrading the community’s tech stack, which now depends on CometBFT and Cosmos-SDK v0.50.
“That is probably the most technically advanced exhausting fork Polygon proof-of-stake (PoS) has seen since its launch in 2020,” Polygon co-founder, Sandeep Nailwal, stated in a July 8 X submit.
Whereas diminished block instances and better community throughput proceed to be the main focus 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 a number of hours of downtime attributable to an error within the Heimdall layer.
On the time, the Polygon workforce stated the Heimdall V1 difficulty was the results of a software program bug that brought on validators to be on totally different variations of the blockchain.
