With private chains, you can have a completely known universe of transaction processors. That appeals to financial institutions that are wary of the bitcoin blockchain.

Blockchain technology, or distributed ledger technology, is just a way of using the modern sciences of encryption to enable entities to share a common infrastructure for database retention.

I have a quantitative background, but really, derivatives appealed to me because they require so much creativity.
