If someone can honestly explain why the blockchain would be any better than the DTCC for tracking equity security ownership I'd love to hear about it.

Not a week goes by on Global Custodian[0] headlines for technology that mentions at least a couple well established firms using blockchain for securities of all sorts.

Whether I agree with these developments or not is completely irrelevant. I'll personally stick to pursing a market neutral strategy and exploiting intraday ETF discrepancies for now.

Harbor and Polymath are working on tokens which can accomplish all those things. The claim is that tokenized securities can reduce the number of middlemen needed to issue new securities, so shares could be traded on individual apartment buildings, etc. Nobody thinks moving Apple stock to a blockchain would change much.

I’m not advocating this argument, just relaying it since you asked.
