Minor benefits around clearing and settlement, but these allow for 24/7 even if the clearing house is not so. On the other hand, I don’t see how they should be able to block it. It is a derivative product, can MSFT block e.g. puts on its stock? Stock ownership gives rights, not obligations.

The other thing would be using it in any other automated whatever that accepts tokens with the same interface. Loans, escrow, trades, whatever it is that someone has built.

There's a lot of technical and other issues with blockchains, but framed as "a single shared database that allows stored procedures and shared data types, with no central owner" I'd hope devs here could see something interesting to mess about with there. If it wasn't for the fact that "a currency" is absurdly easy to make and then there was a lot of quick money to be made or lost, I think it'd be liked more as an odd shared network.

If nothing else, there's some interesting programming challenges involved given the compute limits.
