Please tell us about the organizational structure.

JDA is a non-profit organization that places importance on decentralization. We do not have a Board of Directors, but have established a forum as a place for discussion. The Representative Director will make decisions for the entire association by fully respecting the discussions in the forum. In addition, we will actively establish advisors and subcommittees to emphasize the diversity of opinions. Please note that this is the organizational structure for the first year only, and the structure may be reorganized based on the opinions of the members in the following years.

Regular members are eligible to start and run a subcommittee. Supporting members and individual members are not eligible to become managing members, but can participate in the activities of the subcommittees.

About forum

What is a forum?

The JDA has established a forum to fully reflect the opinions of its members. At the forum, members' opinions are solicited on specific topics. The Representative Director will take the opinions of the Forum into consideration and reflect them in the decision-making process of the JDA as a whole. The Forum is open to non-members as well.

What will be discussed in the forum?

The forum will primarily discuss and vote on the following topics:

  • Exchange of opinions among members on the overview of the hacking incident regarding DeFi and how to respond to it
  • Discussion of the content of the documents that will be created for policy recommendations
  • Selection of speakers for the JDC (Japan DeFi Conference), a DeFi conference organized by the JDA
  • Voting for an annual award to recognize an individual or organization that has done something to symbolize DeFi in that year

Please tell me about voting in the forum.

Votes from people who appear to belong to the same organization will be counted as one vote at the discretion of the Representative Director. Please note that this is to prevent manipulation of decision-making by specific organizations.

Are forum voting rights issued on the blockchain?

The voting rights used in the forum are not issued on the blockchain. This is because issuing voting rights on a blockchain may fall under the category of securities.


I would like to speak at a workshop.

As a general rule, the secretariat requests speakers for study sessions and other events. However, joint planning of study sessions is allowed only when the theme is appropriate. Please contact the secretariat if you are interested in joint planning. Email: office@jda-defi.org
