NOctaHub Limited Nested Hub for Eight Users, Relevant to Eltoo

I've been mulling over an optimization for Eltoo that could come into play once schnorr MuSig is on the table. If anyone spots a major flaw in this or if it’s already been discussed, hit me up. I’ve got a document linked here on github for anyone who wants to check it out or edit it if needed. Edit: Just to clarify, I don’t think it’s right to keep part of this discussion off the forum. Here’s the intro to the document. * NOctaHub Nested Hub for Up to Eight Users So, NOctaHub is aimed at optimizing how we use distributed ledgers. Bitcoin is the most well-known example, tracking participant balances some folks even use it as cash now. It relies on asymmetric cryptography and employs a straightforward stack-based scripting language (similar to Forth) for processing transactions and altering the ledger state. One big hurdle with ledgers like this is scalability. As more users join in, the number of transactions skyrockets. The kicker is that all participants need to audit the ledger to ensure its integrity. Right now, the main bottleneck we face has to do with communication. This leads to two options: one, we might have to compromise the decentralized nature for users with slower network speeds, or two, we could set limits on how much can be recorded on the ledger over time (currently, Bitcoin’s consensus caps block size at around 2MB every 10 minutes). Throughout this document, I’ll be using the term Bitcoin to refer to any kind of programmable distributed ledger.

I've added more description about how Eltoo can adopt this optimization.

We have a live version of Eltoo running on Minima.global now. First live implementation ever, so we believe! https://www.youtube.com/watch?v=889qBgUIrM4 Perhaps we could also implement OctaHubs? Reach out to us in our Discord dev-chat if you are keen

I don't get why 8 members of the multisig are required specifically. Why not 5, or 10? If 256 transactions are signed separately to make this non-interactive, then the problem of unauthorized spending and counterparty risk & punishment is present.
