John Oliver explains Bitcoin, Blockchain & Crypto (with precision & clarity)!

Posted by in categories: bitcoin, cryptocurrencies, economics, finance, internet

John Oliver is a crossover who bridges the art of a comedian with the reporting and perspective of a liberal political pundit. Even detractors acknowledge that Oliver addresses serious issues with unusual wit and humor.

I never thought Oliver could (or would) tackle the topic of cryptocurrency—at least not with value to the viewer. It is too geeky, and too esoteric. (It also cuts into my mission of evangelism and education). smile

He did, and he sparkles! Feel free to jump past the fluff. The Bitcoin tutorial starts at 3:40. Of course, my friend, Shechter, in Long Island New York will bust a gut over what Oliver says at 9:40. It is not only clear and concise, it is accurate and terribly funny!

Whether you are a Bitcoin newbie or a seasoned blockchain coder, this is the video you have been looking for. This one is durable.

What sets cryptocurrencies apart from each other?

Posted by in categories: bitcoin, cryptocurrencies, economics, finance, internet

Today, I was asked to answer this question at Quora:

What sets each cryptocurrency apart from the others?

“Cryptocurrency” is a broad term. It refers to payment coins, of course—such as Bitcoin and Litecoin. But, because most tradeable tokens attain an asset value, the word is often used to refer to smart contract devices, such as Ethereum, a host of other blockchain based tokens, functional Internet-of-Things tokens, and even ICOs (Initial Coin Offerings). Since people treat ICOs and IOT tokens as investment instruments even if they are useless as a payment mechanism, they all fall within the realm of a cryptocurrency.

So, before addressing the question, let’s distinguish between Altcoins and ICOs. I assume the question refers to Altcoins, and not ICOs…

Building a Bitcoin ATM is easy, but…

Posted by in categories: bitcoin, cryptocurrencies, economics, finance, internet

…But offering or operating them engulfs the assembler in a regulatory minefield!

A photo of various Bitcoin ATMs appears at the bottom of this article. My employer, Cryptocurrency Standards Association, shared start-up space at a New York incubator with the maker of a small, wall mounted ATM, like the models shown at top left.

What is Inside a Cryptocurrency ATM?

You could cobble together a Bitcoin ATM with just a cheap Android tablet, a camera, an internet connection, and [optional]: a secure cash drawer with a mechanism to count and dispense currency).* A receipt printer that can also generate a QR code is a nice touch, but you don’t really need one. You can use your screen for the coin transfer and email for a receipt.

What happens to your Bitcoin if you die or forget passwords?

Posted by in categories: bitcoin, cryptocurrencies, economics, finance, internet, law

Legacy Method of Inheriting Assets

Many Bitcoin owners choose to use a custodial account, in which the private keys to a wallet are generated and controlled by their exchange—or even a bank or stock broker. In this case, funds are passed to heirs in the usual way. It works like this…

An executor, probate attorney, or someone with a legal claim contacts the organization that controls the assets. They present a death certificate, medical proxy or power-of-attorney. Just as with your bank account or stocks and bonds, you have the option of listing next of kin and the proportion of your assets that should be distributed to each. These custodial services routinely ask you to list individuals younger than you and alternate heirs, along with their street addresses, in the event that someone you list has died before you.

Of course, Bitcoin purists and Libertarians point out that the legacy method contradicts the whole point of owning a cryptocurrency. Fair enough.

Have there been successful Transaction Malleability attacks?

Posted by in categories: bitcoin, cryptocurrencies, economics, finance, internet

First, let’s get some basics out of the way…

What is Transaction Malleability?

Here are 2 explanations of transaction malleability: [Coindesk] [TechTalk]

In a nutshell, Transaction Malleability is a weakness in the original Bitcoin implementation that enables a bad actor to change the unique ID of a bitcoin transaction before it is confirmed on the Blockchain. Such a change makes it possible for someone to pretend that a transaction didn’t happen, if all necessary conditions are in place.

ICOs & Altcoins rise and fall—yet, Bitcoin endures

Posted by in categories: bitcoin, cryptocurrencies, economics, government

At the end of 2017 and the first months of 2018, we witnessed a surge of interest in Initial Coin Offerings or ICOs. Perhaps the word “interest” gives too much credit to ICOs. Most are scams. ICOs are pushed through by vendor hype, rather than pulled through by investor research. They are almost all pump-and-dump schemes.

But what about Bitcoin? It is not a scam, but questions remain about regulation, intrinsic value* and its likelihood to be superseded by something better. Bitcoin skeptics point to two facts: (1) Bitcoin is open source, and so anyone can create an equally good altcoin. (2) Newer coins incorporate improvements that overcome governance and scaling issues: cost, transaction speed, the burgeoning electric needs of miners, or whatever…

While both statements are true, they miss the point. This is not a VHS-vs-Beta scenario. Bitcoin has achieved a 2-sided network and it is free to fold in every vetted improvement that comes along. For Bitcoin, all those other coins are simply beta tests.

Even the functional tokens will unwittingly feed their “improvements” into Bitcoin. For this reason, it is a safe bet that Bitcoin will reign supreme for years to come—perhaps even long enough for the dominos to fall.

Would an ethical government surrender control of monetary policy?

Posted by in categories: bitcoin, cryptocurrencies, economics, government, internet

Godfrey Bloom is a member of the British Parliament. His in-your-face style of educating and shocking his peers has made him a controversial politician. He has occasionally been escorted out of the assembled parliament because of his rowdy rhetoric.

Consider the video below. Bloom offers a critical, but simple and clear explanation of the Fractional Reserve banking system used in the US and Europe. This gets to the heart of the matter! [continue below video]…

Conclusion (mine, and not Mr. Bloom’s): It is in the interest of governments to use a form of money that they cannot manipulate, print, spend, hide or lend without first earning, taxing or legitimately borrowing — and then balancing the books, openly.

Cryptocurency: Thoughts on a “Korea Krash”

Posted by in categories: bitcoin, cryptocurrencies, economics

If you are reading this on January 16, 2018, then you are aware that Bitcoin (and the exchange rate of most other coins) fell by 20% today. Whenever I encounter a panic sell-off, the first thing that I do is try to ascertain if the fear that sparked the drop is rational.

But what is rational fear? How can you tell if this is the beginning of the end, or simply a transient dip? In my book, rational fears are fundamental facts like these:

  • A new technical flaw is discovered in the math or mining
  • A very major hack or theft has undermined confidence
  • The potential for applications that are fast, fluid and ubiquitous
    has dropped, based on new information*

Conspicuously missing from this list is “government bans” or any regulation that is unenforceable, because it fails to account for the design of what it attempts to regulate. Taxes, accounting guidelines, reporting regulations are all fine! These can be enforced. But banning something that cannot be banned is not a valid reason for instilling fear in those who have a stake in a new product, process, or technology.

Proof-of-Work Alternatives: Massive electric consumption by cryptocurrency mining

Posted by in categories: bitcoin, cryptocurrencies, economics, energy, environmental

Some blogs and news outlets eschew long titles. Publishers want readers to scan a list of topics that fit on one-line each. But, a better title for this article would be:

“Massive electric consumption by cryptocurrency mining:
An unfortunate environmental nightmare will soon pass!
… Proof-of-Work alternatives are on the horizon”

A considerable amount of electricity is used in the process of mining Bitcoin and other cryptocurrencies. Miners are effectively distributed bookkeepers, and this use of resources is part of a system called “proof-of-work”. It keeps the books fair, honest, and without an ability for the miners to collude (In other words, they cannot ‘cook the books’).

Is Cryptocurrency Good for Government?

Posted by in categories: bitcoin, cryptocurrencies, economics

Today, editors at Quora asked me to answer a seemingly simple question:

“Is cryptocurrency good for government?

This is a terrific question, and one that I write about frequently. The question gives me a chance to summarize the key facets of widely mistaken fears. But, here, in the Lifeboat Blog, there is room to elaborate a bit.

In the first phase of cryptocurrency adoption (we are in the midst of this now), there is an abundance of skepticism: Misunderstanding, mistrust, historical comparisons that aren’t comparable, government bans & regulatory proposals—and a lot of questions about intrinsic value, lack of a redemption guaranty, risky open source platforms, tax treatment, etc, etc.
