Today’s show is part 2 of a two-part series all about Bitcoin, other cryptocurrencies, and blockchain technology with TIP’s Co-Founder Preston Pysh. Preston is a graduate of West Point and Johns Hopkins University, the founder of BuffettsBooks.com, and Co-Founder/Co-Host of We Study Billionaires by The Investor’s Podcast Network.

IN THIS EPISODE, YOU’LL LEARN:

  • How Bitcoin works and the problems it looks to solve.
  • Why a higher demand for Bitcoin indirectly makes the currency more secure and in turn a better store of wealth.
  • How investors should think about educating themselves about Bitcoin.
  • Why the adoption of a deflationary currency like Bitcoin will encourage people to think long term and invest more.
  • How to value Bitcoin based on the stock to flow ratio.
  • And much, much more!

In today’s episode, Preston and I continue our conversation from last week. If you haven’t already listened to last week’s show, I’d recommend you go back and listen to it before continuing with this one. Without further delay, let’s jump into Part 2, right where we left off.

Intro  00:19

You’re listening to Millennial Investing by The Investor’s Podcast Network, where your host, Robert Leonard, interviews successful entrepreneurs, business leaders, and investors to help educate and inspire the millennial generation.

Robert Leonard  00:41

It’s kind of hard to fathom, honestly. From someone who doesn’t know a ton about Bitcoin, it’s hard to see why it wouldn’t be better than gold or why it wouldn’t do all the things that you expect it to do. So yeah, I definitely agree with you.

Now let’s talk about mining. We’ve talked about blockchain. We’ve talked about a couple of different cryptocurrencies and Bitcoin. Let’s discuss mining. What exactly is that?

Preston Pysh  01:07

This one’s hard. For somebody who’s not extremely technical to understand this, it’s going to be hard to kind of plow through it, so let me just try to describe it like this. Almost everything that you look at in Bitcoin can almost have a correlation to the physical gold market. So are there companies out there mining for gold right now? Yes, there are. They’re digging the gold out of the ground. How do you know that they’re digging out of the ground? Well, you could look at all their expenses on their income statement; you can see all the hardware, all the equipment, and all the man-hours. When you look at that, and you know the probability of how much resources you have to expend to pull 1 oz. of gold out of the ground, you can get an idea of the amount of work that went into basically achieving that feat of finding something extremely scarce.

With Bitcoin, what you have is a bunch of people that are running their processor on their computer, and they’re trying to solve a puzzle. This is their work. So there’s a riddle that’s published every 10 minutes or until the block is discovered, and the next block occurs. But on average, it’s around 10 minutes. It publishes a riddle basically saying, “Solve this mathematical puzzle that can only be solved through guesswork.”

When you talk about encryption, it’s a one-direction function. Let me give you an example. If you type the word ‘the’, took those three characters, t-h-e, all lowercase, and put them through the SHA256 encryption algorithm, it’s going to always pop out on the right side of the equation; a hash. I’m sure many people have seen a cryptographic hash and it looks like 78arT like it has this big long string, and it pumps out the same length of the string as the output. Now, if you took the word ‘the’, with a capital T, and lowercase h and e, T-h-e, and you put it through the one-way function, it’s going to pump out a completely different hash. If you took an entire book, and you put it as an input to the SHA256 encryption, it’s going to pump out a hash that has the same number of characters as the word ‘the’. And if you ran that entire book, without any of those letters being different through the SHA256 encryption, it’s going to pop it out on the other side. Same thing.

When these miners are trying to solve the puzzle, the Bitcoin protocol says, “Here’s the hash,” but it’s not giving you the full hash. This gets into really complex mathematics, but it’s not giving you the full hash. It’s giving you a portion of the hash. It’s easier to solve than if you had to solve the entire hash. And it’s saying, “Solve this riddle.” The only way you can solve this riddle is by guessing the word or whatever makes up this hash: this one-way encryption output. And so all these processors are guessing, “Oh, I think it’s the word ‘the’. I think it’s the word ‘most.’ I think it’s the word…” I’m dumbing this down as far as how the computers are guessing. 

All these computers are guessing what the input is to that one-way encrypted output. Once a computer solves that, it takes all the transactions that have been requested during that period of time: from when the riddle was put out to the world to be solved. It takes all those transactions that went into the mempool, then basically conducts them through that proof of work that that miner just solved. Then you have a header and a tail inside that block that also has encryption that then gets tied to the very next block that goes.

Long story short, what these miners are doing is, just like if you’re mining gold, they are conducting work to prove that they solved the puzzle. They’re actually securing the transactions because if you wanted to try to go back and undo one of those transactions, you have to go back in time, then be able to solve the next puzzle in addition to the puzzle that you solved, where the original transaction happened. The miners cannot, from a mathematical sense, conduct that, and do it in a manner that is cost-efficient to them for all the work and the energy that they’re consuming to do it.

I don’t know if that did a good job of answering your question, but that’s the best way I can kind of describe something extremely technical.

Robert Leonard  05:54

So with that being so complex, I’m sure we were just touching on the surface. Are coins that don’t require mining better than coins that do require it like say, Bitcoin?

Preston Pysh  06:06

You’re going to get a whole range of opinions on this one, but what I would tell you is I believe that the only reason Bitcoin’s price continues to go up, especially during this first decade of the protocol, is because what you’re doing is this proof of work algorithm. What I just described before was proof of work. And what you’re really implying is a proof of stake mechanism, where the people that own all the units basically have a vested interest in the security of the protocol, so that the protocol doesn’t fail.
