TAPESTRY - A PAYMENTS ROUTER

Tapestry is a set of experiments in developing a multi-scheme “clearing and settlement mechanism” (CSM) for account to account payments between “payment service providers” (PSP) such as banks and other financial institutions. Tapestry is not production quality software. It is best understood in the tradition of operating systems developed to teach computer science concepts. Minix and Xv6 are examples of Unix-like teaching operating systems.
