I think it's kind of odd to draw such a strong comparison to the Bitcoin blockchain. As the technical description [1] points out, the "chainpad" system discards most of the features and properties that make Bitcoin secure against malicious participants. That seems like a totally reasonable design decision for this application, but then describing it as a blockchain just adds confusion.
In fact, the design seems to bear a much closer resemblance to the Bayou optimistic concurrency algorithm [2], with operational transformation as the underlying data model, and some extra crypto on top.
