Federated Bookkeeping is the vision of connecting existing bookkeeping systems together. It uses peer-to-peer messages to connect economic agents, independent of any central authority.
In that sense, it basically builds credit networks on top of e-invoicing .
The bookkeeping messages replace the communication function of payments / currencies / money, but payments are still used to allow trade with strangers. Payments are taken out of the critical path of day-to-day business, but their role as an insurance is retained.
