Proof of Work vs. Proof of Stake [ADB s1e4]

Doctor Bitcoin unpacks proof-of-work and proof-of-stake when securing a blockchain, as well as the importance of understanding the difference between the two methods.

What’s that?

Proof-of-work is the primary method of securing a blockchain. When mining, the node makes a request for the encrypted nugget of data and then attempts to decrypt it by guessing the password. When it does guess the password, the node reaps the award—the block—for decrypting. As more people begin to decrypt the algorithms, the encryptions become increasingly difficult, requiring more processing power to solve. Essentially, the award is the mined block, which proves that you did the work (provided processing power) to crack the encryption.

Proof-of-stake requires you to stake an amount of the tokens you are trying to secure. In this process, you would buy a certain number of tokens, lock them up in a wallet, and each one is a chance to reap the award—the block as it is secured. Instead of using your processing power for a chance to secure the block, you are purchasing tokens for that chance.

Both methods have their positives and negatives. Proof-of-stake is more ecological and efficient but can be more economically unfriendly to the user. Proof-of-work is more energy-expensive and less ecological but also more egalitarian.

“Bitcoin is a fraud,” – JP Morgan CEO Jamie Dimon.

I just can’t stop thinking about how dumb these Dimon quotes are. In case you missed it, the CEO of JP Morgan Jamie Dimon had harsh words for Bitcoin yesterday.

He, during a Barclays conference, called it a “fraud … worse than tulip bulbs, it won’t end well” and that any JPMorgan “trader trading Bitcoin” will be “fired for being stupid.”

Later in the day during an interview at CNBC’s Delivering Alpha conference, he said Bitcoin “is just not a real thing, eventually, it will be closed.”

“Someone’s going to get killed and then the government’s going to come down,” he said. “You just saw in China, governments like to control their money supply.”

Just the way he incoherently is babbling against Bitcoin belies his lack of understanding or even basic research on what its strengths, weaknesses, history, and capabilities are.

This reminds me of a time in my career I spent meeting with newspapers, trying to get them to see the writing on the wall with blogging. For a period of time, in between my career transition as a technology consultant and software developer into a digital journalist, I thought I could straddle the line between both worlds and talk to newspaper publishers, my clients at the time, about the power and opportunity for digital publishing.

On more than one occasion, I sat in a room with an elder suit who patiently listened to my pitch, and then when I was done and opened up for questions dismissively waved his hands.

“Son, our company has been around for over a hundred years,” they’d say, as if they were all reading from the same script. “This internet thing is a blip on the radar. We’ll outlast it.”

It’s hilarious to imagine that level of ignorance now that all publishing is digital publishing, but this was the honest attitude of heritage publishers at the time.

… and look at the type of world we live in with digital publishing. The market landscape is a mix of heritage media that made the transition (like the Washington Post and your local TV affiliates, for instance), and new performers that found out how to bootstrap and thrive in the new landscape (like the Mashable’s and Buzzfeed’s of the world). The roads they took to get there are littered with the bodies of the companies that I wasn’t persistent or talented enough to convince that the internet wasn’t a fad, plus thousands of others.

That the CEO of JP Morgan is claiming that “Bitcoin is a fraud” is rich, coming from the company who, amongst many other banks, represented highly risky financial instruments as safe enough that when they inevitably collapsed (as many predicted they would), the government felt compelled to bail them out to the tune of trillions. It’s also particularly ironic that the same company calling one of the most widely admired financial tech advancements in history a fraud has had such a poor moral and ethical compass as to what constitutes non-criminal behavior, they’ve been forced to pay over $28 billion in fines since that bailout.

Why would he make these explosive statements about Bitcoin, particularly when his company is openly exploring blockchain technology and how to apply it to their work, particularly when one of their former executives (Blythe Masters) has been so famously pro-Bitcoin? Well, there are a few things at play here.

Profits are down 20%. This is probably the biggest thing. Dimon, on many occasions, has expressed his ambivalent disdain for Bitcoin, but he’s saved the unloading of both shotgun barrels for today. The theory some analysts have expressed to me is that there are a great many bitcoin-friendly IRA and 401k options popping up amongst JP Morgan’s competition, an area where they’ve been loathe to go. It’s not a reach to speculate that during one of the most notable meteoric times for cryptocurrencies, people are moving their accounts away from JP Morgan Chase to more crypto-friendly options and contributing to the shortfall.

JP Morgan is under the mistaken impression, as a company, that you can divorce the blockchain from Bitcoin. I’ve been averse to going too deep on this topic publicly because several companies I respect also hold this opinion (including the company that dubbed me a futurist, IBM). In speaking to members of JP Morgan’s fintech innovation team about this news item last night, they expressed the opinion that they view crypto as an “outgrowth technology” of the blockchain. They said this with such conviction that I had to do a sanity check and make sure there wasn’t some obscure historical reference to the term “blockchain” pre-Satoshi Nakamoto. Turns out, I’m not insane, and JP Morgan is dead wrong. Bitcoin is the reference architecture for blockchain. Removing tokenization and crypto components from blockchain strip out key features that make the technology as powerful and compelling as it is (expositing on this topic is something I’m happy to do at length, but would distract from the topic of this post. If you see me in a bar, come with a nice whiskey neat and ask me this question, and block off the rest of your night).

General denial. Just as blogs didn’t really kill off the idea of the media company, blockchain and bitcoin don’t make obsolete the concept of banks. Very much like the media landscape, however, there is going to be a very drastic redefinition of what banking means. This is inevitable. It probably means the death of multimillion dollar CEOs of international banking conglomerates, and he’s feeling general revulsion at the concept of the floor dropping out from underneath him. More on these concepts later – they’re much deeper than the analysis on this news event will allow for exposition on, but it’s a transformation I’m obviously watching closely, and developing some specific predictions around.

I started writing this around 9 AM, when markets were plummeting down below $4,300 to the $3,750 range. As I’m typing this around 3 PM, markets are rebounding, now coming back closer to $3,840. It’s unfortunate that the opinion of one man has shaken confidence as much as it has, but this is one of the effects of disintermediation between experienced investors and the buckets of money they manage.

As they used to say about all Microsoft software in the ’90s: it’s not a bug, it’s an undocumented feature.

How to Securely Liquidate Your Bitcoin Cash

The Roger Wilco Agency has issued a report titled How to Obtain & Convert Your “Bitcoin Cash”, commissioned by bitqyck, Inc, which reveals that there is “an overbearing elephant in the room of this amazing technology called Bitcoin: ridiculously long transaction resolution times.” The decentralized nature of Bitcoin makes it attractive to a global audience and creates greater financial security because the value of the tokens is not susceptible to the stability of any particular political or economic entity – but the shared ownership can also have its challenges. Software developers who work on Bitcoin’s core code have spent considerable effort in an attempt to find a solution for the long transaction resolution times.

Bitcoin is based on mathematical proof rather than the characteristics defined by a political entity, and the code is open source, providing transparency. The ability to create alternative groups, called pools, allows for participants known as miners to create a permanent divergence in the blockchain, known as a fork. The original Bitcoin software client will likely be the most valuable and stable for some time to come, and any new fork will succeed or fail based on widespread acceptance by participants or their decision not to use that client. As the software developers politicked in reaching a fix for the issues with transaction resolution, a small group called the User Activated Hard Fork (UAHF) rejected the solution and created a hard fork known as Bitcoin Cash.

On August 1, 2017, the Bitcoin blockchain split, creating a second set of tokens, with Bitcoin (BTC) as the original and Bitcoin Cash (BCC or BCH) as the new blockchain, according to Bitcoin Cash 101: What Users Need to Know Before the Fork published by Coindesk. This split resulted in the doubling of coins possessed by anyone who controlled their private keys. The Roger Wilco report indicates that the value of the coins in this new blockchain may be at risk, because “as many predicted, the tools, mining, support and code around ‘Bitcoin Cash’ are very weak and unreliable.” This report further advises that any BCC held should be “immediately liquidated.”

The Roger Wilco report was created to facilitate a secure and expedient method to liquidate newly acquired Bitcoin Cash. While there are multiple methods that can work, the report details and illustrates a specific method that is the most secure and least likely to end up with a compromised wallet. The report includes step-by-step instructions on how to claim control of these new tokens as well as how to sell them and transfer their value to your regular wallet. Bitcoin value was $4,601.10 and Bitcoin Cash value was $633.17 as of August 6, 2017.

Ask Doctor Bitcoin: A Quick Crypto FAQ.

For those who don’t know, I’m a cryptocurrency fan. I’ve been following all of this very closely since 2011, and I enjoy learning more technical details around blockchain as well as theorizing and architecting new solutions utilizing blockchain.

I also sell cryptocurrency through my company, Roger Wilco.

I have this conversation. A lot.

As such, this week perhaps more than most others, I’ve been getting a lot of the same questions due to the volatility in the markets. Rather than constantly repeat myself, I figured I’d answer all the questions here and legitimately try to save some time.

  1. Do you sell <insert cryptocurrency name here>?
    Yes. I denominate all sales in Bitcoin, but as long as you have a wallet set up, I can usually find a way to send you your value in the cryptocurrency you want.
  2. Holy cow. <insert cryptocurrency name> is up/down.
    Yep.
  3. Are you concerned/excited?
    Sorta. I don’t really watch the minute-by-minute charts.
  4. But it’s really down/up! You sure you still are pro-<insert cryptocurrency name>?
    Yes. Still.
  5. It’s been some time since you posted this. Are you still pro-cryptocurrency? Like for reaslies?
    Yes. Super-dooper for realsies.
  6. Should I buy/sell? How much?
    If you’re asking if you should buy crypto in general, the answer is yes. If you want my recommendations on which ones you should go with, I can give you my answer, which will be based off my opinions around the underlying team and technology, not what I believe the value ought to be. If you’re asking how much you should put in, I’ll always tell you to dollar cost average exactly what you can afford to.
  7. Dollar cost average?
    Yes. It’s the only reliable way to increase your net value.
  8. But what do you think the price of <insert cryptocurrency here> will be?
    I’m Doctor Bitcoin, not Wizard Bitcoin. Not sure.
