Problem: Payjoin transactions i= mprove privacy but require coordination and sharing of UTXOs with untrusted= users.

Solution: Octojoin allows users to include multiple inpu= ts in a transaction, some with histories linked to other users, making it d= ifficult for on-chain analysts to determine ownership.

Basic idea is to be like Octopus and hide in plain sight by looking = like a normal bitcoin transaction. This will also increase the usage of swa= ps and allow users to sell statecoins generated using coinjoined UTXOs.

Let me know if I missed somet= hing important or other feedback which can help in improving Octojoin.
