Danake is a lightweight micropayment system which allows anonymous services to bill for resource usage without compromising privacy or performance. It is named in reference to the danake, a silver coin of the Persian empire commonly placed in the mouth of the deceased to pay for passage into the underworld.

Using Danake, a service provider can issue credits to users based on some application-dependent policy, and allow those users to anonymously spend those credits to pay for services. The exact policy is considered out-of-scope for Danake itself, but for instance, a service provider could periodically issue credits to each user, or allow users to purchase credits using Zcash, etc.

Danake is a work-in-progress, and this document will continue to evolve over time. The table of contents is visible on the left or via the menu button at top-left. This document also supports full-text search, available by pressing s.
