Authored by States of Jersey and published on 09 April 2018.


Can you please confirm whether any States of Jersey computers currently store copies of the so-called 'blockchain' for the digital cryptocurrency Bitcoin? If yes, which States Department(s) and how many computers store this data in total?

I note that the States of Jersey, in conjunction with the Jersey Financial Services Commission, announced the first regulated Bitcoin investment fund back in 2014. Additionally, the Financial Crime Strategy Group announced they were analysing digital cryptocurrencies at about the same time.


The States of Jersey does not hold this information. Article 3 of the Freedom of Information (Jersey) Law 2011 has been applied.

Bitcoin is a cryptocurrency that exists on a distributed ledger – often referred to as a ‘blockchain’. The distributed ledger Bitcoin operates on is a public ledger, and therefore it is not possible to ‘store’ copies of the entire ledger per se as it is a living ledger.

The States of Jersey’s existing controls would prevent the installation of any cryptocurrency management or mining components.

Article applied:

(b) it is held by another person on behalf of the authority.
