Pizza Block: Designing Artefacts and Roleplay to Understand Decentralised Identity Management Systems

This pictorial describes in detail the design, and multiple iterations, of PizzaBlock - a role-playing game and design workshop to introduce non-technical participants to decentralised identity management systems. We have so far played this game with six different audiences, with over one hundred participants - iterating the design of the artefacts and gameplay each time. In this pictorial, we reflect on this RtD project to unpack: a) How we designed artefacts and roleplay to explore decentralised technologies and networks; b) How we communicated the key challenges and parametersof a complex system, through the production of a playable, interactive, analogue representation of that technology; c) How we struck a balance between playful tangible gameplay and high fidelity technical analogy; and d) How approaches like Pizza Block invite engagement with complex infrastructures and can support more participatory approaches to their design.
