Payosha256 Authentication System

Catagolue uses the Payment Over SHA-256 (affectionately known as payosha256) protocol for authentication and spam-filtration. It is based on the HashCash proof-of-work system developed by Adam Back. To use the system, you need to create a payosha256 key, which requires you to be logged in to your Google account.
