Had Some understanding issues of your theory:
1, It's says BTC is Pseudonymous (Neither transactions or accounts are connected to real world identities): But due to the KYC process this point is breaking right?
2. Why this transaction data are encrypting? What is the technical value of it? However miners have to do random guesses and validate the Tx infomations.
What's the purpose of encrypting the data?
3. Fast and global: This is depends with the miners, right?
