Renovatio monetae

This silver pfennig from the Archbishopric of Magdeburg (1152-1192) was subject to a policy of renovatio monetae. Twice a year whoever held it had to bring it in to be changed for new coins at a rate of four old coins to three new coins. That suggests an annualized tax rate on co … | Continue reading

Thoughts on the Tornado Cash defence and what happens when everyone adopts it

Payments companies are regularly punished for engaging in money laundering. MoneyGram, for instance, has has to pay multiple fines. Western Union was famously busted in 2017.

Why I'm in favor of financial illiteracy

I'm not a fan of mandatory investor education classes. The issue was brought up recently by former chair of FDIC, Sheila Bair, who sees early financial education as ways to stop future FTX-style disasters. The model of finance I've been using for many years is the fairly dismal d … | Continue reading

The effects of Russian sanctions as portrayed in YouTube videos

How PayPal can use stablecoins to avoid AML requirements and make big profits

There's a new financial loophole in town: stablecoins. Stablecoins are dollar, yen, or pound-based payments platforms that are built using crypto database technology.

Have the sanctions on Russia failed?

I very much enjoy economist Robin Brooks's tweets, especially his charts showing how sanctions imposed on Russia have affected regional trade patterns.

It's time to get rid of "crypto"

Call me a pedant, but I'm not a fan of the word "crypto". It may have been a serviceable category back in 2011 when there was only one type of crypto thingy – bitcoin. But it's ceased to be a meaningful term and, if anything, it causes a regression in understanding. Source: Fidel … | Continue reading

Why my favorite coinage is Byzantine coinage

What do I like about Byzantine coinage? Most people probably admire the Byzantine solidus, a gold coin that maintained its weight and purity for over 600 years, which is quite remarkable for a coin. The solidus was exported all over the world, including to Europe, which lacked go … | Continue reading

Do bitcoin ETFs conflict with bitcoin's original ethos?

Some folks are suggesting that a bitcoin ETF is absurd because it doesn't fit with Bitcoin's original ethos. On the contrary, I think it's a nice snug fit. It would be a misunderstanding of bitcoin's history to assume that it was the idealism of cypherpunk-ism that gave birth to … | Continue reading

It's time to impose Iran-calibre sanctions on Russia

Are flatcoins a good idea?
