I’ve been at a few events recently where people talk about the “market cap(italisation)” of utility tokens issued in ICOs, and comparing them to the market cap of cryptocurrencies or (even worse) listed companies. This is truly dreadful and misleading, perhaps sometimes intentionally so. In this post I introduce two useful metrics for comparing across ICOs: the Reserve ratio, and the Commitment ratio.
For a non-hypey introduction to ICOs please see A gentle introduction to ICOs.
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 Trezor which you can buy for €89 directly from their website.
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.

I’m absolutely thrilled to be able to write about the open sourcing of Project Ubin Phase II, a key project that our team has been working on for the past seven months with the Monetary Authority of Singapore (MAS), ten banks, and our partner Accenture.
What is Project Ubin? It’s probably the most advanced starter kit out there for anyone wanting to explore blockchains for banking:
Some technology startup companies are raising money in a new way, by issuing digital tokens in return for funds. This is often colloquially called “doing an ICO”, and this article aims to explain how this works.
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.
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.
This article attempts to explain the difference between the revolutionary disruptive innovation of bitcoin and the evolutionary efficiency innovations of industry workflow tools, and why calling them both “blockchains”, even as a generic term, is incredibly confusing.
For the rest of this post, I will use the phrase “industry workflow tools” instead of industry blockchains, as some of the emerging solutions being proposed in this space are not blockchains (eg, R3’s Corda is not a blockchain but Digital Asset’s solutions are – however, both companies are proposing industry workflow tools).
