Paper Title: A Decision Model for Decentralized Autonomous Organization Platform Selection: Three Industry Case Studies.


  1. Decentralized autonomous organizations as a new form of online governance are collections of smart contracts deployed on a blockchain platform that intercede groups of people.

  2. A growing number of Decentralized Autonomous Organization Platforms, such as Aragon and Colony, have been introduced in the market to facilitate the development process of such organizations.

  3. Selecting the best fitting platform is challenging for the organizations, as a significant number of decision criteria, such as popularity, developer availability, governance issues, and consistent documentation of such platforms, should be considered.

  4. Additionally, decision-makers at the organizations are not experts in every domain, so they must continuously acquire volatile knowledge regarding such platforms and keep themselves updated.

  5. Accordingly, a decision model is required to analyze the decision criteria using systematic identification and evaluation of potential alternative solutions for a development project. 

  6. This work develops a theoretical framework to assist software engineers with a set of Multi-Criteria Decision-Making problems in software production.
