How DPR might spend his millions from inside of prison
I spent some time thinking about how DPR might spend his millions from behind bars. Here's what I came up with. Can you do better? Imagine that DPR is in prison and he's got 80 million dollars worth of BTC in a brainwallet. For example, all stored with the passphrase "correct horse battery staple" (c.h.b.s for short). The Feds want that money and they're definitely not going to let him send it to anyone so they're not letting him use a computer, especially not one connected to the internet. If he had access to a computer, he could write a transaction from behind bars and pass it on a piece of paper to someone on the outside. But he doesn't. And if he did, that computer would have a keylogger. His next alternative is to write c.h.b.s on a piece of paper and pass that to someone. But he'd then be trusting all his 80 million to one person. That's not safe, either. Assuming some planning, maybe he divided up his money into tens of thousands of bitcoin addresses, each one with, say, 20BTC. Now he can give out private keys as needed, written down, and spend money in increments of 20BTC. The problem with that is that he has to memorize thousands of passphrases. One option, he could use:
but someone would catch on to the pattern and take all his money. In prison he might have books. Instead of numbers, he could use the first letter of words in a line from a book, like Romeo and Juliet. Like this:
"c.h.b.s Thbaid" (Two households, both alike in dignity,)
"c.h.b.s IfVwwlos" (In fair Verona, where we lay our scene,)
"c.h.b.s Fagbtnm" (From ancient grudge break to new mutiny,)
Hash("c.h.b.s 1") -> 0101010100101... (many, many bits)
Hash("c.h.b.s 2") -> 1010101110100... (etc)
A deck of cards is surprisingly strong. The order of a random deck of cards is about 200bits of entropy, even more than a 160bit bitcoin hash, so a deck of cards could be useful. That's as far as I got. Any better ideas? How do you store 10,000 brainwallets in your brain without using a computer? Or make transactions without a computer?
Those looking for an update or revision of what Schneier wrote 15 years ago in this edition (issued this month) will be disappointed — it is the same book. So the strengths remain. This, I believe, is one of two flaws in a widely circulated anti-blockchain screed by Bruce Schneier, who made no reference to the ongoing work of engineers, regulators, and business leaders who are constantly improving this new value exchange system so it can eventually work at scale in the real world. Digital currency mining, through SHA-256 for Bitcoin, Scrypt for many other currencies, and a plethora of other algorithms that have been developed, is a growing industry, with Bitcoin mining, and Scrypt mining, machines being created that cost $10,000+.. So, Why Do People Mine Digital Currencies? Mining is the primary method for transaction processing, recording, and security for most digital New laws will help build cyber resilience: Bruce Schneier. New laws are the only thing that will incentivize companies to look at security as more of blended-in rather than bolted-on said Bruce. 28 May, 2018, 12.31 PM IST About Bruce Schneier.
