Fixing Inclusion Issues On Parachains Side

inWhitelisted Caller
2 years ago
Executed

This morning CEST Kusama parachains stopped including blocks. The cause was a dispute in a finalized block that stopped the inclusion of new blocks from parachains.

After the chain issued a revert, it "freezes" the current chain to not include any new parachain candidates. As the block was already finalized, we could not revert to and continued producing on this chain. So, the chain currently is rejecting any new parachain candidates. force_unfreeze reverts the freeze. This proposal aims to fix this, for chains to continue with block inclusion.
