• [SKYWAY] CHORE to inspect jailing mechanism for quadratic jailing due to validator evidence missing VolumeFi/paloma#2905

Background

• no more jail backoff, default duration is now 12 hours
• skyway attestations are now expected to be fully attested within 300 blocks of being first reported
• if a skyway attestation takes longer than 300 blocks, Paloma will proceed to jail validators which have so far not reported the claim as seen (within network stability limits)
• the jail duration for missing a skyway attestation is 24h
• both the default jail duration and the skyway jail duration may be configured by updating the params of the valset module
• to update said params, simply create a new vote which results in a x/valset/types/MsgUpdateParams once passed. You may define the new parameters in this message. The interactive draft-proposal CLI will help with it
