Polygon network faces interruption for several hours after…… an upgrade

Netflix and Polygon collaborated to develop NFTs for Autism Awareness

Ethereum scaling solution at layer 2 Polygon has been without a fresh block for nearly 11 hours, with creators blaming the problem on a network update.

 Users are questioning why the layer-2 scaling solution has been offline for nearly 11 hours, and what is causing the delay in correcting a fault that has jeopardized network consensus. 

When did the downtime begin?

Polygon network developers informed users on the project’s forum on Thursday at 4:20 p.m. UTC that there would be downtime beginning about 5:50 p.m. UTC due to maintenance required on one of the network’s three tiers. An issue in the network’s ability to reach consensus is considered to have been caused by a recent upgrade.

“We suspect there may have been a bug in the upgrade which affected consensus and caused different Heimdall validators to be on different versions of the chin, thereby not reaching ⅔ consensus.”

Polygon Team Response

The disruption began about 5:54 p.m. UTC, as expected. At about 1:30 a.m. UTC, the Polygon team published an update, stating that it was still trying to resolve the issue and that a hotfix had been deployed to allow users to continue creating blocks. As of this writing, the hotfix does not appear to have taken effect. Users can also rest certain that all funds and data stored on the blockchain are secure. Polygon users seemed to understand that the outage was expected, but by the sixth hour, there were rumblings in the community. 

The Consumer Dissatisfaction

The majority of consumers have expressed their dissatisfaction with the length of the outage. Others have stated that the interruption has harmed their profession or cryptocurrency business. 

@Miklos211, a Twitter user, said: 

‘I’m literally unable to work thanks to that, could you please send us a time where we can expect the network to be back on?”

What Are The Three Levels Polygon Network

The Polygon network is made up of three levels, each of which serves a distinct purpose. 

  1. The Ethereum layer runs smart contracts, and 
  2. The Bor layer aids in the generation of blocks. 
  3. Heimdall is a collection of proof-of-stake (PoS) nodes that aid in network consensus. 

The fault lies in the third Heimdall layer. Polygon is unable to obtain network consensus on the Heimdall issue.


Polygon’s most recent big problem put $24 billion in funds at risk, however, it was resolved without incident by the end of 2021. Polygon recently announced a partnership with TokenTraxx, a multichain music nonfungible tokens (NFT) marketplace, to support the marketplace in the Polygon ecosystem. TokenTraxx will enable musicians to tokenize and sell their work as NFTs.
