A fractional reserve crisis

This is a slightly amended version of a keynote speech I gave on 14th April 2023 at the University of Ghent, for the Workshop on Fintech 2023.  The crisis that has engulfed crypto in the last year is a crisis of fractional reserve banking. Silvergate Bank and Signature Bank NY were fractional reserve banks. So too were Celsius Network, Voyager, BlockFi, Babel Finance and FTX. And still standing are the crypto fractional reserve banks Coinbase, Gemini, Binance, Nexo, MakerDAO, Tether,...

And they went on about network routing protocols and Dijkstra's algorithm. Someone even sent me a spec for an onion routing protocol for the Lightning network. I read it and sighed. They had completely missed the point. To be sure, I had made an incorrect assumption about Lightning. I assumed that Lightning devs respected property rights. It turns out that...
