Central Judicial Collection Agency

The Central Judicial Collection Agency (CJIB) is part of the Ministry of Justice and Safety in the Netherlands. It is responsible for collecting a range of Dutch fines and penalties, and is the designated authority for the EU’s Cross Border Enforcement Directive in the Netherlands. CJIB provides the national coordination service for custodial sentences, arrest warrants, community service orders, and probation services; it also provides a Victims Information Service.

CJIB’s will build a system using blockchain technology and a ‘zero knowledge proof’ to allow citizens to directly flag to the CJIB if they are unable to pay fines while maintaining their privacy, and to link this declaration with a certification from local services that they are providing debt support. Through participation in BLING, CJIB can transfer knowledge about this multi-stakeholder approach and can pilot with other beneficiaries and work together on joint solutions.

CJIB focusses on delivering the “Digital Data Safe” pilot, under the sponsorship of the Dutch Ministry of Justice, with local governments across the Netherlands (e.g. Groningen). The pilot will use blockchain’s identity- and information-management tools, together with a zero knowledge proof (a system where one party can prove to another that they know a piece of information, without conveying any other information apart from the fact that they know the information).
