But a popular pattern in the crypto/token/blockchain world is that someone will come along and be like “finally, through tokenization, we have invented a way to slice _________ into bits and let people trade the bits.” I always find this a bit confusing. Whatever _________ is, it is safe to say that before the invention of tokenization there was already a way to slice it into bits and let people trade the bits. Slicing things into tradeable bits has been a very hot area of finance for a very long time, and people got pretty good at it. Real estate is a popular target for tokenization, for instance, and I am confused because real estate securitization—not so much mortgage-backed securities but real estate investment trusts—is a thing that has existed for a long time.
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.
Yesterday I did an recording where the interviewer asked me a simple question – what is blockchain? This got me thinking – I had no go-to answer for this. People use this word to cover a wide range of networks and platforms, and some platforms such as R3’s Corda (Note: I work at R3) are categorised as “blockchain” platforms, when they don’t even bundle transactions into blocks!
The best description I could come up with was:
Blockchain is a word used to describe a bundle of technologies that allow digital assets to be created and passed from party to party with guarantees that the assets are authentic and haven’t been copied or counterfeited all without needing to trust a third party to open and maintain accounts for customers.
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 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:
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.
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.
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 partnerAccenture.
What is Project Ubin? It’s probably the most advanced starter kit out there for anyone wanting to explore blockchains for banking:
