Quoting Wikipedia: "Several companies have sued the DTCC, without success, over delivery failures in their stocks, alleging culpability for naked short selling.

Doesn't sound that trustless to me. With a decentralized setup as in Quorum at least everybody can calculate how much they have to trust the miners.
If your company has miners of their own, you are part of the whole system and not just using a third party service.

- bhaak 8y agoThanks for the link. I knew there were other consensus algorithms possible but I didn't know of any specific example. The main point still stands though, the different consensus algorithm allow you more insight than a simple centralized DB that is just a black box.
- askmike 8y agoI agree very much. I have worked on quorum based blockchain systems for bank consortiums in the past.
