A Reference Architecture for Activities-as-Asset Distributed Ledger with Secure Private Computation

Abstract

This paper describes a reference architecture for a secure Activity-as-Asset (AaA) ecosystem on the Algorand Blockchain system. It has built-in persistent personal ownership of data while allowing the sale of singletime data usage contracts to enterprises. This system would allow users to deny enterprises access to their own personal data at any time, even if they have sold access to that same data in the past.
