Polygon to Launch Heimdall v.0.2.8 Upgrade.
Following Polygon’s network outage last week, the blockchain project has announced that it will implement a hard fork on Heimdall, which will see the system upgraded to v0.2.8.
The unexpected network upgrade is expected to be completed before altitude 8664000, at approximately Friday, March 18, 2022, around 10:30 AM UTC.
The popular layer-2 Ethereum scaling solution suffered a network outage that lasted for more than 11 hours on March 11th, with the network not producing a new block throughout the outage.
On March 15th, Binance suspended Polygon deposits withdrawals to sync nodes for a limited period of time.
The issue started after the network completed a technical upgrade, causing the inability of Polygon to achieve consensus.
Announcing the unfortunate development to its community at the time, Polygon said:
“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 chain, thereby not reaching 2/3 consensus.”
To provide a temporary solution to the issue, Polygon unblocked the bor and created a few spans that replicated the previous one before the network stopped working.
The created spans are expected to function until March 20, 2022. However, to avoid encountering any further issues, Polygon wants to ensure that Heimdall is functioning as it should.
Based on this, it would be launching the Heimdall Hard Fork, hoping that the upgrade would create a lasting solution to the network outage.
