Investing.com – Polygon’s network was unavailable between Thursday evening and Friday morning. According to the Polygon team, all user funds are safe.
Polygon developers have indeed notified users of a potential network shutdown due to a planned network upgrade named Heimdall. The Heimdall implementation is used by one of the two layers of the network’s proof-of-stake chain.
The definitive cause of the shutdown has yet to be determined, however, and appears to stem from an earlier update consisting of a Polygon PoS state sync/bridging module setting fix.
The team also revealed that there “may have been a bug” in the upgrade, which impacted consensus and led to different Heimdall validators being on different versions of the blockchain. This prevented them from reaching the 2/3 consensus.
According to the developers, Heimdall does not manage user transactions, but is only used for bridges and transactions related to validators. However, Polygon’s PoS chain named Bor, which is aimed at users, was also shut down because it relies on Heimdall for “block proposal committee selection.”
According to the team, Polygon’s network operations have been restored through an interim fix, although the bridge itself “will not be active until we fully resolve the issue.”
However, the full functionalities of the network will not be active until a permanent solution is in place.
