Query: Blockchain and Beyond: Understanding Blockchains through Prototypes and
  Public Engagement   This paper presents an annotated portfolio of projects that seek to
understand and communicate the social and societal implications of blockchains,
distributed ledgers and smart contracts. These complex technologies rely on
human and technical factors to deliver cryptocurrencies, shared computation and
trustless protocols but have a secondary benefit in providing a moment to
re-think many aspects of society, and imagine alternative possibilities. The
projects use design and HCI methods to relate blockchains to a range of topics,
including global supply chains, delivery infrastructure, smart grids,
volunteering and charitable giving, through engaging publics, exploring ideas
and speculating on possible futures. Based on an extensive annotated portfolio
we draw out learning for the design of blockchain systems, broadening
participation and surfacing questions around imaginaries, social implications
and engagement with new technology. This paints a comprehensive picture of how
HCI and design can shape understandings of the future of complex technologies.
