Key crypto case tracker

The canon of caselaw around how we define, interact and transact with crypto assets starts in 2019 and below is a list of key examples that have helped shape the legal frameworks around how best to freeze, recover, and or generally deal with those assets.

Given the inherent use of pseudonymisation when reviewing blockchain ledgers, cases involving the recovery of crypto assets tend, by their nature, to require categories of Defendants listed as Persons Unknown. In this instance, the First Defendant is the person(s) who caused the fraud, the Second Defendant represents a class of individuals who, following disclosure from relevant centralised entities, are identified as taking receipt of the misappropriated funds, and the remaining Defendants are centralised entities, usually exchanges who can freeze funds and provide that disclosure.

Other cases include those where individuals are seeking recourse against centralised entities for providing financial products in contravention to the Financial Services and Markets Act 2000 and or The Financial Services and Markets Act 2000 (Regulated Activities) Order 2001, or where there is a contractual or tortious dispute around crypto assets of business which rely on blockchain technology.
