> There's no technical reason why internal accounting systems didn't post to a Blockchain based ledger.

I agree. Using the main chain obviously costs network fees, which for the high amount of transactions involved in running an exchange is untenable. However, there's no reason an exchange couldn't use its own public blockchain to allow independent auditing.

Not to my knowledge, and I know some crypto projects would love to use a product like this. Could be worth doing some market research.

However, what's holding any company back from releasing a read-only connection to their live financial systems?
