The Polygon Heimdall V2 mainnet, the consensus consumer for the Polygon proof-of-stake chain, went down on Wednesday because of a suspected “consensus bug,” the Polygon group 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 response to an replace from Polygon.
The disruption lasted one hour and was brought on by an unidentified validator’s exit from the community, Polygon spokespersons advised 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 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 because of rising community complexity.

Heimdall V2 improve goes dwell
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 laborious fork Polygon proof-of-stake (PoS) has seen since its launch in 2020,” Polygon co-founder, Sandeep Nailwal, mentioned 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 because of an error within the Heimdall layer.
On the time, the Polygon group mentioned the Heimdall V1 challenge was the results of a software program bug that induced validators to be on totally different variations of the blockchain.
