Proposal: refund slashed collators during relay chain incident

This proposal aims to refund Astar collators who were mistakenly slashed during the Polkadot “dispute” incident.
During this time, a lot of Astar blocks were rejected by Polkadot validators while the collators could do nothing to fix it.
Details of the incident here:

Period: 11/03/2023 15:00 UTC to 13/03/2023 09:00 UTC

Number of slashes: 7

I wanted to ask why only 7 collators were slashed if there was a mistake caused by Polkadot. Given that there are many permissionless collators registered in the network, why were other collators not affected and able to continue producing blocks?

The Polkadot validators were randomly rejecting a lot of blocks.
Collators are assigned round robin to collate blocks, they have ~4 slots / era.
If collators get all their blocks rejected during 2 eras, they get slashed.
Others were able to produce 1 block / era or something around that.


Completely agree on this proposal! Fortunately I was not affected on Astar, but I was affected on Shiden and I know that was an ExpectChaos weekend!

I totally agree with the proposal, and glad to know that Astar is doing fine overall, I know a few other parachains got affected


The proposal is approved. Please proceed.

I agree on this, it can be a good idea

All collators slashed have been refunded.
