Zcash Token Service

This repository contains a prototype implementation of a token service (described in this paper) and based on the privacypass implementation in Tapir.

client/client.go implements the client portion, generating a set of tokens and sending these to the zcash token service through an encrypted memo along with payment and a return address.

server/server.go implements the server portion, polling zcash for new transactions, signing the tokens it receives along with a proof and sending both back through an encrypted memo to the specified return address.
