In my opinion, DDOs and DAOs, as terms, are nearly the same thing, with the major differences centered on the:
- need for a blockchain, and
- focus on organizational design.
First, DDOs do not need to be wholly or partially operational/formed on a blockchain, while for DAOs this is a necessity.
Second, the term DDO focuses more on organization design rather than technological design. For a DDO, it first needs to be digital (i.e., using some form of information and communications tech (ICT) primarily for governance and operations), and then needs to be decentralized (i.e., practicing decentralized/distributed governance and using decentralized/open source tech).
While I feel that DAOs are only focused on the technological basis of the organization’s governance or operations (wholly or partially), which must be a blockchain and/or use of crypto-primitives, but does not actually require any use of decentralized governance within the organization.
Those are my thoughts on the difference between the two terms.
