Paying for things online usually means giving up plenty of privacy. But this needn't always be the case. Last night I donated to a local charity via their website and didn't have to give up any of my personal information. The trick for achieving a degree of online payments anonymity? Not bitcoin, Zcash, or Monero. I used a product created by old fashioned bankers: a non-reloadable prepaid debit card. (I wrote about these cards here and here ). Had I used a credit card or PayPal, all sorts of parties would have gotten access to my personal information including the site owner, the payments processor, my bank, the site owner's bank, the credit card networks, my partner, and many more. To get a good feel for how many different parties touch an online payment, check out this graphic by Rebecka Ricks, which shows how PayPal shares your information.

Reuters and Coindesk report that that the People's Bank of China's imminent central bank digital currency (CBDC) is going to have a feature called controllable anonymity . Perhaps some wires have been crossed in the translation, but it'd be hard to come up with a more Orwellian piece of double speak than this. Plenty of people on Twitter are sneering. But in this post I'm going to take China's side, if only tepidly. None of the news articles have made much of an effort to explain controllable anonymity . But we've actually known about this feature for quite some time. Back in 2018, the project's head, Yao Qian, provided a short description of it. It's not as Orwellian as it seems. China's new CBDC, otherwise known as the Digital Currency Electronic Payment (DCEP) platform, requires users to provide their real identities when they sign up. In the link above Yao calls this real-name at back-end . So the People's Bank of China will be privy to ...

Antony Lewis recently published a useful article on stablecoins. In it he describes something called "permissioned pseudonymity". In traditional payments systems, people only get to access to payments services after opening an account. This requires that they provide suitable identification. So these systems are not pseudonymous. Usage and personal identity are linked. Stablecoins operators, on the other hand, sever this link. Users can transfer stablecoins to other users without providing personal information. John Doe can pay Jane Doe, no questions asked. Antony calls this permissioned pseudonymity because regulators permit pseudonymous usage of stablecoin networks. 🚨 🚨 30,000,000 #USDC (29,926,581 USD) transferred from unknown wallet to unknown wallet Tx: https://t.co/ujdi6cvpZ8 — Whale Alert (@whale_alert) October 9, 2019 The above payment is an example of permissioned pseudonymity.

Last week, we finally got some information about what Libra's currency basket would look like. A Libra currency basket will reportedly include... -no Chinese yuan -50% dollar -18% euro -14% yen -11% pound -7% Singapore dollar https://t.co/YNbRY9Q02x Libra could have automated the decision by adopting an established unit of account, say the IMF's SDR... — John Paul Koning (@jp_koning) September 20, 2019 If you haven't heard, Libra is a proposed global blockchain-based payments network. It is being spearheaded by Facebook along with a coalition of other companies including Uber, MasterCard, PayPal, and Visa. The hook is that rather than going the conventional route and expressing monetary values using existing units-of-account like the dollar, yen, pound, or euro, the Libra network will rely on its own bespoke Libra unit-of-account as its "base language." Libra originally revealed in its whitepaper that the Libra unit would be defined as a basket, or cocktail, of ...

When it comes to financial privacy, good old fashioned banknotes and privacy cryptocurrencies like Zcash & Monero get all the attention. But as I recently wrote for the Sound Money Project, let's not forget about prepaid debit cards. Having written a bunch of posts over the last two years about financial privacy, I recently decided that it was time to step up my own personal financial privacy game. A few months ago I walked into my local pharmacy and bought my first non-reloadable prepaid debit card (i.e. gift card), a Vanilla card. You've probably seen the rack of prepaid cards near the front of pharmacies and department stores. Some of them are closed-loo p cards. They can only be used to buy things at the issuer, say Tim Horton's or Starbucks. But some of them, like my new Vanilla Prepaid card, are open-loop cards. That means they can be used wherever Visa or MasterCard are accepted. In Canada, Vanilla cards are sold in denominations from $25 to $250. The Vanilla c...

I was disappointed to see that First Trust Bank, a commercial bank based in Northern Ireland, will stop issuing its own brand of banknotes. Under different names , First Trust has been in the business of providing paper money for almost two hundred years, starting with the Provincial Bank of Ireland back in 1825. Source: First Trust 99.9% of the world's population uses government-issued banknotes. A small sliver of us—those who live in Northern Island, Scotland, Hong Kong, and Macau—get to use privately-issued banknotes. Prior to First Trust's announcement, I count twelve private issuers scattered across the globe: Northern Ireland : Bank of Ireland, Danske Bank (formerly Northern Bank), First Trust Bank, and Ulster Bank Scotland : Bank of Scotland, Clydesdale Bank and The Royal Bank of Scotland Hong Kong : HSBC, Standard Chartered, Bank of China (Hong Kong) Macau : Banco Nacional Ultramarino, Bank of China (Macau) Now there are just eleven. To our modern sensibilities, priv...

A few centuries ago, lack of fungibility used to be a big weakness of monetary systems. But technological and legal developments eventually solved the problem. Nascent systems like bitcoin are finding that they must wrestle all over again with fungibility issues. Fungibility exists when one member of a population of items is perfectly interchangeable with another. So for instance, because your grain of wheat can be swapped out with my grain without causing any sort of change to our relative status, we would say that wheat grains are fungible. Fungibility is a desirable property of a monetary system. If all monetary items are interchangeable, then trade can proceed relatively smoothly. If monetary items are not fungible, then sellers cannot accept the monetary item without pausing for a few moments to verify and assay it, and this imposes frictions on trade.    In this post I argue that there are two ways for something to be fungible. They can be fungible for physical reasons or for leg...

Ken Rogoff has famously called for a ban on high denomination banknotes in order to help combat tax evasion and hurt criminals. But rather than banning notes, why not implement a market-based approach such as a tax? Among other advantages, a tax leaves people with flexibility to determine the cheapest way to reduce their usage of the targeted commodity. This is how society is choosing to reduce green house gas emissions. So why not go the tax route for banknotes too? My recent post for the Sound Money Project on pricing financial anonymity delves into this idea. The anonymity provided by banknotes is both a "good" and a "bad". People have a legitimate demand for financial alone time ; a safe zone where neither their friends, family, government, nor any other third-party can watch what they are buying or selling. These days, cash is pretty much the only way to get this alone time. But cash's lack of a paper trail can be abused when it used to evade taxes. The r...
