Collective Contributory Concensus
Using musig to create a master threshold key m made up of k contributory keys. You then broadcast a transaction but require the master key to sign aswell and since you need majority keys to contribute for the sig to be valid if it's constructed you know that majority have validated and committed to it being valid u using threshold s. You then just sign utxos without any blocks needed since a constructed sig already proves consensus. Key distribution can be done to as many independent actors as desired. Given propagation time of 0.2s a hop you can get concensus for 5k nodes within 2.5s. boot strapping can use the same system to do a utxo commit every few 5m allowing full current state verification knowing the majority of the network agrees.
Just a thought
I really do not get your point from this, can you take time to explain in detail your point so that it would be very clear to all because I do not see this as a good way to market a product as it is not clear.
