Top 20 Coins: Uncommon Core Podcast Episode 15

Throwing this up for discoverability: I enjoy the Uncommon Core podcast and this is a helpful episode for those looking to get a quick summary of the top coins by market cap as at December 2020, as discussed by prominent crypto trader Su Zhu of Three Arrows Capital and prominent researcher Hasu of Deribit.

Errors in summary notes are my own. I haven’t fact-checked. Assume the podcasters may have long or short positions in any of these coins. I note the the podcasters are quite diplomatic about how they describe these coins.

Note: This was broadcast on Dec 11, before Bitcoin reached its all time high and before the SEC lawsuit against Ripple and its cofounders.

Audiobook Launch – The Basics of Bitcoins and Blockchains

Happy news! (and some insights into the mechanics of authoring and publishing a little further down the page)

I’ve just been told that the audiobook version of my book “The Basics of Bitcoins and Blockchains” is now available for preorder on Audible. It’s a great use of your Audible credits! If you’re not already on Audible, you get your first listen for free when you sign up. Click it!

This means you can upskill on bitcoin, blockchains, payments, and money when you’re out and about (ha)… Or more likely, when you’re inside, trying not to go insane, and wishing you could be out and about. What a great use of lockdown time!

CBDC, DLT, Crypto, Stablecoin Resources List

I’m often asked for material about CBDCs (central bank digital currencies), blockchains / distributed ledgers, stablecoins, and cryptocurrencies. So here’s a list of reports from central banks, regulators, international organisations and other agencies. Enjoy!

Bitcoin’s payments are not peer-to-peer!

This post is adapted from an article first published on R3’s Medium.

In this post I articulate what a peer-to-peer transaction is, why Bitcoin transactions are not peer-to-peer, and why it is important to understand the differences clearly. I describe the benefits of peer-to-peer transactions and discuss that Corda is the closest architecture to take advantage of those benefits.

The Basics of Bitcoins and Blockchains

Last December I was approached by a publisher, Mango, who asked me if I would write a book about blockchain technology.  A little nervously, I agreed, and I’m excited to announce the result of six months of effort:

The basics of bitcoins and blockchains - book cover

The Basics of Bitcoins and Blockchains is an essential guide for anyone who needs to learn about cryptocurrencies, ICOs, and business blockchains.  Written in plain English, it provides a balanced and hype-free grounding in the essential concepts behind the revolutionary technology.

I wrote The Basics for an audience of business people, students, practitioners, and those who are simply interested in this technology.  I tried to make it entertaining even for those who are already working in the cryptocurrency or blockchain industry.  For example, did you know:

Frictionless Tokens Create Friction

We’re gonna need another intermediary…

In 2013-15 it was trendy for online merchants to pretend to accept bitcoin as payment. It was a very cheap way to get positive media mentions and seem innovative. Overstock, Dell, Tiger direct… they were all at it after they realised it was all media upside. Even Virgin Galactic accepted bitcoin as payment for trips to space at some point (Note: I think paying for a trip to space with bitcoins is actually quite cool).

Bitcoin Price, Gold, and Nonsense – How Not to Value Bitcoins

Important note: If you own more than $1,000 worth of cryptocurrency then you should definitely be using a hardware wallet instead of keeping coins on exchanges.  I recommend a Ledger Nano (S or Z) which you should buy directly from their website and never second hand.


Every few days I hear the argument “If x% of the money in gold (or other asset class) moved into bitcoin, a single bitcoin should be worth $y”.  This article explains why this argument is utter nonsense.

The (flawed) reasoning is as follows: the total value of gold in circulation is estimated at US$8 trillion.  If some small fraction of the people holding gold (say, 5%) sold their gold for US Dollars (releasing $400 bn), and the USD proceeds were used to buy bitcoins, the total value of bitcoins (commonly referred to as “market capitalisation”) would increase by that amount of dollars ($400bn), and because we know the total number of bitcoins in circulation, we can derive a price per bitcoin.

In a nutshell: Ian Grigg’s Ricardian contracts and digital assets prehistory

I enjoyed listening to Episode 151 of the podcast “Epicenter” (previously “Epicenter Bitcoin”) featuring Ian Grigg, inventor of Ricardian Contracts and blogger at Financial Cryptography. Here are my notes – part transcription, with some edits. This one is a goldmine and covers many topics: bonds, contracts, cash, Chaumian e-cash, DigiCash, financial cryptography, Ricardian contracts, digital signatures, smart contracts, dispute resolution, Ethereum, triple entry book-keeping, oh my!

Misunderstandings and paraphrasing errors are entirely mine.

This gets fairly technical; if this is hard to follow, it may be helpful to read my introduction to smart contracts first.  Hmm, if it’s still hard to follow, also read about blockchains and bitcoin and Ethereum, and digital tokens.

The emergence of blockchains as Activity Registers

This post tries to describe two very different uses for blockchain technology: Digital Token Ledgers that record ownership changes of digital tokens, and Activity Registers that record timestamped proofs of existence of data or agreements about data.  Bitcoin is used for both.
