Author Moritz Armingeon, [email protected]

Luzon is a TaaL (Token-as-a-License) implementation. This prototype is a floating license system as a decentralised application. I built Luzon within my Master Thesis Project. The report is available upon request.

Taal is the name of a volcano on the Philippine island Luzon.
