You have a similar gossip except it pulls from the: fastest, most data-full, and responsive nodes around you. I think I saw 100 peer connections but again, it takes EVERYTHING as a transaction, indexes, then if that transaction is ever found in a block it validates. It doesn't filter as the transaction comes in.

That sounds like something knots people wouldn't want. Why accept everything? Isn't the idea of knots to filter things that are unwanted?
You take everything because disk is the cheapest resource (also frees up RAM for the actuall chain), and mining is what determines what goes in so, if you have literally EVERYTHING, you as a miner do the filtering.
Paired with Stratum V2 or Datum, this means there is a truly decentralized immutable way of CHOOSING what you want your proof of work to put on chain.
The chain cannot fit in RAM
Lol, I'm telling you that the architecture is wild but using self-validated "checkpoints" as they call them, you can fit the highest chain on RAM. (The guy was using 128G of RAM) but yes, they did.
