Bitcoin L2 concept: Quantum-inspired transaction compression

[Jonny_840]

Hey guys,looking for some feedback on a idea I got the other day,so The concept is inspired by a physics phenomenon called Bose-Einstein Condensate.Basically,it is a state where atoms collapse into a single "super-atom" and move with basically zero friction.Right now,Bitcoin transactions are like people crowded in a line,fighting for block space with higher fees.So it gave me an idea like could we implement those principles in L2 protocol so that it takes thousands of different user transactions,strip away the individual data noise,and condenses them into one single "super-transaction".By leveraging Bitcoin Taproot and Schnorr signature aggregation,we could settle thousands of payments on L1 using just one single 64-byte signature.It would drastically clear up block space and make transaction fees practically zero for the end-user.
Just to be clear that this is strictly a raw concept and a thought experiment.I want to hear your opinions on this,does it make any sense or are there massive roadblocks I am missing?

If I understand your concept correctly, then it already exists: it is called Cross-Input signature aggregation.

There's also a thread about that here on bitcointalk.

To summarize the last "state of things" I'm aware of: Many devs think it's interesting, but there are some practical challenges to overcome. That's why there is still no complete draft or BIP. It seems to be more likely to enable this for individual transactions (e.g. CoinJoins) than for complete blocks to be "aggregated".

It's also not really a L2 topic, although afaik rollups work a bit in a similar way.
