According to various reports, Polygon (MATIC) issue is believed to come from an earlier upgrade to the blockchain.

In addition, the team emphasizes that proof-of-stake (PoS) users will “likely experience downtime” early today.

Furthermore, reports states that the outages issues come from Polygon’s Heimdall node, which acts as a verifier layer that creates checkpoints.

However, the exact cause has not been found. But the team states that the issue arose from a “minor parameterization fix” to a module that acts as a proof-of-stake (PoS) bridge between Ethereum and Polygon.

Aside from this, reports notes that the bug may have caused Heimdall validators to start using different chain versions, therefore failing to reach 2/3 consensus and halting Heimdall.


More so, the team also declared that a possible Heimdall outage would also halt Polygon’s Bor node, a block producer layer and which is the “user-facing Proof-of-Stake chain.”

Moving further, the team reassure that user funds are safe, as Heimdall only handles validator transactions, not transactions between customers.

Note that the team warned about a possible downtime that was expected to start at 5:50 PM UTC on March 10. This was confirmed by the Polygon block explorer Polygonscan at around 9:50 PM UTC that there have been no new blocks for four hours.


Note that, in January, Polygon faced some issues that were previously reported. Also, the team behind the blockchain released some statements at the time, suggesting that problems were due to high demand rather than a technical issue. For instance, Polygon’s MATIC token is down 2.3% over the past 24 hours, according to CoinMarketCap.
