For context. I have been looking for a tool that would help people with similar values find each other. A VAN would be a great network structure when searching for payment pathways in a large credit network such as Ripplepay classic (this is not the blockchain-Ripple). It would create a more meaningful usage behavior of the payment system by prioritizing paths with people you share values with and let them get the transaction fees.
This is an introduction to the system I am trying to build. It is not based on the blockchain. The ledgers are instead only visible to pairs of people.
I am currently thinking it could be created as a plugin to the decentralized app Signal. And people would be able to connect to search engines for finding transaction paths. And paths returned by the search engines would contain public keys to encrypt payments like an onion all the way between two points. No individual in the chain would know where the payment started or where it is going.
