thinkBLOCKtank roots back to the Berlin BlockchainHub which formed an international legal working group in 2016. The German legal community organized in various working groups of the Blockchain Bundesverband (the German Blockchain association, founded in June 2017), and the Finance Working Group issued its initial “Token Regulation Paper” in February 2018 and the extended German version in April 2018.

In 2017, the Swiss Crypto Valley Association was formally established as an association to coordinate, accelerate, and scale the further development of blockchain projects and was collaborating with the Blockchain Bundesverband from the early stages.

Several members of thinkBLOCKtank are also participants of the annual meetings of the Wharton@RegTech group of global regulators, lawyers and practitioners at the University of Pennsylvania.

The Finance Working Group of the Blockchain Bundesverband initiated a meeting of the EU members of BlockchainHub’s international legal working group on the Token Investment Summit 2018 on 16 April 2018 in Vienna in an effort to create an EU wide token regulation paper.

The EU group met again in June in Berlin, discussing the restructured paper and presenting its findings on a first public meetup which was joined by Peteris Zilgalvis, Head Of Unit, Start-Ups and Innovation, Digital Single Market Directorate J.D. at the European Commission.

The group had been hosted by the Blockchain Bundesverband but due to its EU-wide reach decided to form a specific legal/tax/accounting think tank for publishing its EU-wide token regulation paper. The thinkBLOCKtank was formally launched at a meeting on 28 November 2018 in Luxembourg, where the group also hosted a second public meetup including a presentation of Sorin Cristescu of the European Commission's Blockchain Competence Centre.

Following its formal launch, the thinkBLOCKtank submitted a proposal regarding the regulatory priorities to prepare the Workshop on Blockchains & Smart Contracts Legal and Regulatory Framework by the EU Blockchain Observatory and Forum on 12 December 2018 in Paris and attended the preparation meeting for the creation of the "International Association for Trusted Blockchain Applications" on 17 December 2018 in Brussels.

The members of the thinkBLOCKtank share a history of collaborating in the field of Blockchain regulation and aim for creating transparency in close collaboration with regulators and law makers.
