> The "blockchain-based" part is misleading.

I don't agree. Maybe for one who doesn't understand what a blockchain is and only has an association with crypto currencies. They are just using a private blockchain as a ledger for all commits to the database. It seems a bit far fetched to me to assume they chose this core technology to "capitalize on the cryptocurrency hype".

They use blockchain as a synonym of "distributed ledger" (which blockchain is not just.) However, a distributed merkle tree is most of the "block and chain" part of the bitcoin paper. Yet, like other people in this thread, I believe Blockchain has come to include distributed consensus or byzantine fault tolerance, proof of work, and public keys as identities. Just because the word itself wasnt defined in the Bitcoin whitepaper, doesnt mean it hasnt been defined after the fact.

They also claim to have used it two years before bitcoin existed.
