Topic: Intermediaries Who Must Not Be Named? A Legal & Policy Research Agenda for Crypto Miners

Cryptoeconomic systems are often said to lack intermediaries and to facilitate the peer-to-peer transfer of digital assets. This view of them undergirds much legal, policy, and risk analysis, as systems without intermediaries are said to lack the risks posed by intermediaries. In her paper, Walch critiques the common view, and argues that crypto miners function as intermediaries in cryptoeconomic systems, providing examples from real-world events and computer science research to support the claim. She then presents a research agenda to explore the ways miners act as intermediaries, and the legal, policy, and risk questions that arise. She introduces the concepts of ‘intermittent intermediaries,’ ‘fractured intermediaries,’ and ‘limited intermediaries’ to frame the discussion of the role played by crypto miners, and provides guiding principles for research that acknowledge the different roles played in mining ecosystems, that each blockchain system is unique, and that the tech and practices in the field are rapidly evolving.
