In Alexander’s post he writes about how Runchey authored a distributed systems architecture which relies on digital signatures that use a series of unified constraints including timestamps and geolocational data. This creates a form of multiple mints independent of one another. This system, like Bitcoin’s, requires no central authority and where the transactions are protected from attack by their performance in a similar concept to proof of work. Runchey had patented this invention in 2007, before Nakamoto’s release of Bitcoin in 2008.
