If operators only keep multi-sigs, - so, they not need to run a full bicoin node? it's easy to become operator, if so! (I assume, they not need, - and it makes your idea much better than lightning network, and it may easily become viral here, in nostr) What if several of multi-sig operators agree between themseles to steal funds? their own actives will be confiscated by other quorum (higher-level)? (I assume yes; but what if higher-level quorum are malicious, and/or controlled by one person silently?) What if confiscated actives will be less than stealed? (for example, stealed 0.01 btc but available for confiscation is 0.006 btc) (I don't know, answer, please?)
