Rather than settling for governance infrastructure that is just good enough to get the job done, we opted to create what we consider to be the ideal infrastructure for self-governance of a cryptocurrency. We call our system for storing governance data Politeia, which is based on the ancient Greek term, meaning “a system of government”. Politeia is a system for storing off-chain data that is both versioned and timestamped, essentially “git, a popular revision control system, plus timestamping”. Instead of attempting to store all the data related to Decred’s governance on-chain, we have opted to create an off-chain store of data that is anchored into Decred’s blockchain, minimizing its on-chain footprint. While we will use it first as the basis for our proposal system, it has been developed as a generic tool that allows its users to create and maintain arbitrary data in a version-controlled and timestamped environment. Politeia can be used without holding any decred, although it does depend on using a dcrtime server for creating timestamps. In addition to making the initial release of Politeia, we are excited to announce a competition for projects based on Politeia, with winners announced at an event in Austin, Texas on December 1st, 2017. The prizes for 1st, 2nd and 3rd place will be the equivalent of USD 10,000, USD 5,000 and USD 2,000, respectively, paid in decred.
