Our Story

The Blockchain Forum ry was established in March 2017 by three of the most prominent players in the Finnish technology ecosystem: Tomi Dahlberg, Markus Lehtonen and Teemu Rissanen. 

In this initial phase, emphasis was given in providing the information needed for companies and institutions to start to explore blockchain.

The 2018 and 2019 editions of the Blockchain Summit Helsinki were held.

At the end of 2019, the Forum began a new phase, becoming more community-based, open and international
The official working language changed from Finnish to English. This change made the local ecosystem more diverse and inclusive, with the Forum’s content and events reaching a wider audience.

In 2020, the Blockchain Summit Helsinki was held online for the very first time. An active Telegram group was also created to establish a more digital community.

Starting from 2021, in addition to its original tasks, the Blockchain Forum will tackle yet another key project. 
In partnership with the City of Helsinki, it will be responsible for the creation of the Helsinki Blockchain Center, which will serve as a hub for the development of Distributed Ledger Technologies in Finland. 
With the Center, the country will be able to show all of its strength and knowledge in this technology essential for the Fourth Industrial Revolution. 


Working Groups

The Blockchain Forum has five Thematic Working Groups, which are focused on particular aspects, implications and technologies.
