How Paypal robs the Bank of England

Digital currencies might start creating a sticky situation for central banks.

Have you ever wondered how the rise of digital currencies will impact on the monetary base, and the effects that will have on seigniorage revenue to governments worldwide? No? Well, this pair of articles by the Financial Times' Izabella Kaminska, "Why central banks should take charge of their digital currencies" and "Turning mobile money into M0" is interesting nonetheless.

Kaminska examines the typical problem central banks have with digital currencies, which is that they tend to mess around with the way banks expect the money supply of the nation to work. The immediate downside of that is that it impacts on seigniorage, the revenue accrued to a government by its right to mint coinage.

In other words, when you use PayPal rather than posting a £50 note, you need never hold that currency, and the government never receives the revenue for having printed it.

She writes:

Consequently, what you end up with is something very different to cash of the realm. In many ways, it’s worse than zero-yielding money due to the natural decay associated with transactional, creation and redemption costs. The other point is that Safaricom [the vendor of a hugely popular Kenyan mobile currency] is actually behaving much like a quasi-autonomous state within a state that’s issuing its own private money system, the value of which is constantly pegged to the official currency of the land.

How can nations fight back? (Assuming, of course, they ought to fight back — but that revenue is likely to be mighty tempting.) One possibility is by working with digital currency vendors to create payment mechanisms which don't require holding a parallel currency to work. And make no mistake, even though PayPal denominates its accounts in pounds and dollars, it's a parallel currency in all but name.

Jean-François Groff, one of the pioneers of the Web at CERN, is working on that option. Mobino, his company, is a mobile payment system which works on real-time debiting, not on keeping a float of a second currency on tap:

Mobino’s system aims to cut out as many intermediaries from the debit process as possible by getting you, the customer, to strike up a single direct debit agreement with itself. The company then charges the customer for transactions conducted with partner vendors, whilst the customer deals only with Mobino rather than a multitude of online or retail vendors.

And if that scheme was done by Mobino — or a similar system — working with a central bank, then the costs of running it could be funded from the seigniorage revenue it returns to the government. Rather than the cost of "printing" money being the actual ink and paper, it would become the price of maintaining servers and bandwidth.

In an ideal state-controlled money world, you could imagine the system mutating into one where the central bank itself ended up billing you directly for the use of their digital cash. So, rather than withdrawing physical cash to conduct your payments, you’d be transacting state-issued digital cash, now credited or debited from your account as quickly as a bank credits or debits cash to you at the ATM wall.

But, while Kaminska mentions it in passing, it would be interesting to see the analysis applied to Bitcoin. Lord knows the currency has its flaws, but it's the only one of the successful(ish) mobile payment systems which actually embraces the fact that it is a parallel currency — and a freely floating one, at that. The Bitcoin ecosystem has a specific method for distributing the seigniorage it generates, but also gradually reduces that rate; by 2140, the system will likely be in de-facto deflation.

By moving the transaction entirely into a parallel currency, the system is also more efficient than even Mobino could ever hope to be — provided you don't plan on converting Bitcoins into real-world money. If you do, things get trickier; the exchanges have had a number of high-profile failures, and are probably the weakest point in a network which manages to combine cryptographic perfection with an incredible amount of possibilities for human error.

It may be the case that central banks have to start examining what their role would be in a world of digital currencies; but if they do, it may be better for them to skip the sticking-plaster world of PayPal and Mobino and move straight to something designed for an all-digital world from the start.

This Ada Lovelace Day, let’s celebrate women in tech while confronting its sexist culture

In an industry where men hold most of the jobs and write most of the code, celebrating women's contributions on one day a year isn't enough. 

Ada Lovelace wrote the world’s first computer program. In the 1840s Charles Babbage, now known as the “father of the computer”, designed (though never built) the “Analytical Engine”, a machine which could accurately and reproducibly calculate the answers to maths problems. While translating an article by an Italian mathematician about the machine, Lovelace included a written algorithm for which would allow the engine to calculate a sequence of Bernoulli numbers.

Around 170 years later, Whitney Wolfe, one of the founders of dating app Tinder, was allegedly forced to resign from the company. According to a lawsuit she later filed against the app and its parent company, she had her co-founder title removed because, the male founders argued, it would look “slutty”, and because “Facebook and Snapchat don’t have girl founders. It just makes it look like Tinder was some accident". (They settled out of court.)

Today, 13 October, is Ada Lovelace day – an international celebration of inspirational women in science, technology, engineering and mathematics (STEM). It’s lucky we have this day of remembrance, because, as Wolfe’s story demonstrates, we also spend a lot of time forgetting and sidelining women in tech. In the wash of pale male founders of the tech giants that rule the industry,we don't often think about the women that shaped its foundations: Judith Estrin, one of the designers of TCP/IP, for example, or Radia Perlman, inventor of the spanning-tree protocol. Both inventions sound complicated, and they are – they’re some of the vital building blocks that allow the internet to function. 

And yet David Streitfield, a Pulitzer-prize winning journalist, someow felt it accurate to write in 2012: “Men invented the internet. And not just any men. Men with pocket protectors. Men who idolised Mr Spock and cried when Steve Jobs died.”

Perhaps we forget about tech's founding women because the needle has swung so far into the other direction. A huge proportion – perhaps even 90 per cent - of the world’s code is written by men. At Google, women fill 17 per cent of technical roles. At Facebook, 15 per cent. Over 90 per cent of the code respositories on Github, an online service used throughout the industry, are owned by men. Yet it's also hard to believe that this erasure of women's role in tech is completely accidental. As Elissa Shevinsky writes in the introduction to a collection of essays on gender in tech, Lean Out: “This myth of the nerdy male founder has been perpetuated by men who found this story favourable."

Does it matter? It’s hard to believe that it doesn’t. Our society is increasingly defined and delineated by code and the things it builds. Small slip-ups, like the lack of a period tracker on the original Apple Watch, or fitness trackers too big for some women’s wrists, gesture to the fact that these technologies are built by male-dominated teams, for a male audience.

In Lean Out, one essay written by a Twitter-based “start-up dinosaur” (don’t ask) explains how dangerous it is to allow one small segment of society to built the future for the rest of us:

If you let someone else build tomorrow, tomorrow will belong to someone else. They will build a better tomorrow for everyone like them… For tomorrow to be for everyone, everyone needs to be the one [sic] that build it.

So where did all the women go? How did we get from a rash of female inventors to a situation where the major female presence at an Apple iPhone launch is a model’s face projected onto a screen and photoshopped into a smile by a male demonstrator?

The toxic culture of many tech workplaces could be a cause or an effect of the lack of women in the industry, but it certainly can’t make make it easy to stay. Behaviours range from the ignorant - Martha Lane-Fox, founder of, often asked “what happens if you get pregnant?” at investors' meetings - to the much more sinister. An essay in Lean Out by Katy Levinson details her experiences of sexual harassment while working in tech: 

I have had interviewers attempt to solicit sexual favors from me mid-interview and discuss in significant detail precisely what they would like to do. All of these things have happened either in Silicon Valley working in tech, in an educational institution to get me there, or in a technical internship.

Others featured in the book joined in with the low-level sexism and racism  of their male colleagues in order to "fit in" and deflect negative attention. Erica Joy writes that while working in IT at the University of Alaska as the only woman (and only black person) on her team, she laughed at colleagues' "terribly racist and sexist jokes" and "co-opted their negative attitudes”. 

The casual culture and allegedly meritocratic hierarchies of tech companies may actually be encouraging this discriminatory atmosphere. HR and the strict reporting procedures of large corporates at least give those suffering from discrimination a place to go. A casual office environment can discourage reporting or calling out prejudiced humour or remarks. Brook Shelley, a woman who transitioned while working in tech, notes: "No one wants to be the office mother". So instead, you join in and hope for the best. 

And, of course, there's no reason why people working in tech would have fewer issues with discrimination than those in other industries. A childhood spent as a "nerd" can also spawn its own brand of misogyny - Katherine Cross writes in Lean Out that “to many of these men [working in these fields] is all too easy to subconciously confound women who say ‘this is sexist’ with the young girls who said… ‘You’re gross and a creep and I’ll never date you'". During GamerGate, Anita Sarkeesian was often called a "prom queen" by trolls. 

When I spoke to Alexa Clay, entrepreneur and co-author of the Misfit Economy, she confirmed that there's a strange, low-lurking sexism in the start-up economy: “They have all very open and free, but underneath it there's still something really patriarchal.” Start-ups, after all, are a culture which celebrates risk-taking, something which women are societally discouraged from doing. As Clay says, 

“Men are allowed to fail in tech. You have these young guys who these old guys adopt and mentor. If his app doesn’t work, the mentor just shrugs it off. I would not be able ot get away with that, and I think women and minorities aren't allowed to take the same amount of risks, particularly in these communities. If you fail, no one's saying that's fine.

The conclusion of Lean Out, and of women in tech I have spoken to, isn’t that more women, over time, will enter these industries and seamlessly integrate – it’s that tech culture needs to change, or its lack of diversity will become even more severe. Shevinsky writes:

The reason why we don't have more women in tech is not because of a lack of STEM education. It's because too many high profile and influential individuals and subcultures within the tech industry have ignored or outright mistreated women applicants and employees. To be succinct—the problem isn't women, it's tech culture.

Software engineer Kate Heddleston has a wonderful and chilling metaphor about the way we treat women in STEM. Women are, she writes, the “canary in the coal mine”. If one dies, surely you should take that as a sign that the mine is uninhabitable – that there’s something toxic in the air. “Instead, the industry is looking at the canary, wondering why it can’t breathe, saying ‘Lean in, canary, lean in!’. When one canary dies they get a new one because getting more canaries is how you fix the lack of canaries, right? Except the problem is that there isn't enough oxygen in the coal mine, not that there are too few canaries.” We need more women in STEM, and, I’d argue, in tech in particular, but we need to make sure the air is breatheable first.
