 # Abstract
 Blockchain technology falls into two distinct classes: open (permissionless) blockchains such as those underlying bitcoin, Ethereum and Cardano; and closed (permissioned) blockchains such as implemented in the Hyperledger Fabric project. To motivate decentralised participation, open blockchains (presently) require an associated cryptocurrency, which can be a risky distraction. However, closed blockchains are considered by some to be insufficiently decentralised.This summer project aims to prototype a compromise: a closed blockchain system that encodes voting rules about self-governance, so that closed blockchain technology can be used in a more open manner. Experience in programming blockchain systems is not assumed. Depending on the student involved, the project will balance work between design and modelling of the blockchain governance rules, and implementation of such a rule set over an existing closed blockchain system.
