This article examines the compatibility of the Global Conference on Criminal Finances and Cryptocurrencies with a sharing economy model. The analysis is based on the claims presented in Europol documents and public statements of Europol executives that this initiative serves as a platform for knowledge exchange and building professional networks between public and private actors to tackle crypto-laundering. The article investigates the validity of these statements with the most prominent sharing economy concepts: low barrier accessibility, transaction cost and trust-building. The article employs each sharing economy concept on two beneficiaries of the platform—law enforcement agencies (LEAs) and non-governmental organizations—while scaling the platform’s sharing economy level. Based on Europol documents, an expert interview and participant observation of the 5th Global Cryptocurrency Conference, the article’s core argument is that these cryptocurrency conferences can be categorized as a ‘partial’ sharing economy platform. They reduce the transaction cost for public and private actors to share knowledge about the latest trends and threats about crypto-laundering and reduce transaction costs for networking. However, co-founders should consider integrating robust trust-building mechanisms that allow low barrier entry to the conference, which will facilitate more inclusive and optimized public−private partnerships (P3).
