The week-long event brought together investigators, cryptocurrency experts and data scientists in a coordinated push to track down individuals and organisations perpetrating tax crimes around the world.

The event brought together experts from the UK, US, Canada, Australia and the Netherlands, with the mission of optimising the use of data acquired from a variety of open and investigative sources available to each country.

This year’s Challenge focused on data mining and financial reporting relating to crypto-assets and technology enabled financial threats.

Using various analytical tools, members of each country were put into teams and tasked with generating leads and finding cryptocurrency related tax offenders, based on the new data available to them through the Challenge.
