I read David because I can never accurately predict his opinion, which means either it's all signal, or he is in fact a natural source of randomness, both of which are highly valuable.

Turning Japanese

The Japanese edition of “Before Babylon, Beyond Bitcoin” has been published, which is very exciting. I’ve now been published in English, Italian, Turkish and Japanese so I’m beginning to feel like a real author!


El Mariachi and Me

I’ll be interviewing Antonio Banderas (yes, that Antonio Banderas) live on stage at Money2020 in Amsterdam. He is an investor in an identity and authentication startup called Biocryptology, and I’ll be talking to him and the CEO Ted Oorbals in the afternoon keynote at 3.25pm about the identity problem and what their solution offers.


Money 2020 Vegas Confirmed

Happy to say that I will be presenting at Money2020 in Las Vegas this year. and I look forward to meeting friends old and new there.


I am delighted to say that I will be speaking at the GSMA Mobile 360 event on “Privacy & Security” in The Hague at the end of May. I’ll be speaking in Keynote Session 2 “Architecting for Data, Privacy and Cybersecurity” and I’ll be talking about how “the blockchain” (by which I mean the family of shared ledger technologies and related cryptographic techniques) can help to deliver both security and privacy in the mass market.

Moneybox Live

I was invited along to BBC Radio’s flagship personal finance programme, MoneyBox Live, to talk about the use of cash and the coming cashless society. I was in some pretty good company! Along with the wonderful host, Paul Lewis, were Victoria Clelland (Chief Cashier at the Bank of England and the woman whose signature is on our banknotes) and Andrew Cregan (Head of Payments Policy at the British Retail Consortium.

You can listen to the show here.

The Open Up Challenge

I was very flattered to be asked, and delighted to be able to accept, to become one of the judges for the Open Up Challenge,  a £2.5m prize fund backing ambitious products that will help small businesses save time and money, find better services, reduce stress and discover the intelligence in their financial data.

The Open Up Challenge is run by Nesta’s Challenge Prize Centre, through Nesta’s wholly owned subsidiary Nesta Enterprises Limited.

The prize is backed by the Competition & Markets Authority (CMA), with funding from eight of the UK’s largest providers of SME banking: Barclays, HSBC, Lloyds Banking Group, RBS, Santander, AIB Group (UK) p.l.c, Bank of Ireland UK and Danske Bank. The Challenge forms part of a package of CMA remedies aimed at shaking up retail banking and sits at the heart of the UK's open banking agenda.

What’s ICO all about?

A date for your diaries: on Monday April 9th I have been invited along to the Financial Services Club in London to give a talk about the world of tokens and ICOs. With cumulative ICO funding heading towards $9 billion (see below), it’s a good time to take a look at the phenomenon and see if there is any intellectual superstructure we can use to support  token market of the future.

I’ll be explaining why I don’t think this world is as mad as it seems and why the financial services industry will be exploiting a regulation token marketplace in the near future. For more information and to register for the talk, please visit The Financial Services Club.

Wired World 2018

I was delighted to be a contributor to Wired magazine’s Wired World issue for 2018. They asked me to write something about fintech, so I chose Open Banking as my theme. You can read the article here.

Top 100 Identity Leader

I was flattered to be named one of the “top 100 leaders in identity” by the good people at One World Identity. What’s more imporant though is that I am part of a network of really great people who are thinking differently about the role of identity in the modern world and who genuinely want to change it for the better. Thanks to all of them for making me smarter.

Quartz/Retro Future of Money

I took part in the “Future of Money” short film put together by Erik German for Quartz and RetroReport. It’s a super piece of work, drawing on one of my favourite “back to the future” themes and using the famous stone money of Yap to explain Bitcoin.

The core idea is discussed in the film is that money is a form of memory. The memory of communities. It used to be dumb as rocks, but we are moving into an era of smart money.
