If that is possible, then it might as well already exist in the network. Find an exploit yourself, as they are well incentivized. If you get to find a well-hidden exploit, expect good donations coming from many sources.

If we are talking about how paranoid we are about tech, then why don't you start from point zero? Hardware and OS. Do you trust that your hardware components do not have backdoors that could put your funds or personal information under risk? Do you really trust the entire OS you're using? Do you trust hardware wallets, especially since Ledger's have a closed source component?

The fact that you have written what you have written here is based on "blind trust" of your keyboard and operating system. When you open up Bitcoin Core, you blindly trust the OS that it doesn't take your .dat file and broadcast it to a number of 3-letter agencies.

But Bitcoin is different. You can read every single line of its code. If you cannot trust even that, then I guess tech isn't for you!
