Even JPMorgan is getting on the Ethereum bandwagon, although they have a potentially pernicious aspect to their work. They have been working to create a private blockchain for member banks which will keep secret the identity of which member bank has engaged in a transaction. Only member banks will be able to use the insider chain, but it will stay linked to the public chain for public transactions.
This anonymity feature is troubling. If all the member banks have to be trusted by all the other member banks in order to be a member, then why hide their identities? Hiding the identity of those who sell naked short contracts in the gold market is what makes it possible to get away with all the manipulation that occurs in the gold market. If a cookie gets stolen out of the cookie jar, and all of the kids can shrug their shoulders and say, "We don't know who took it, " then mischief is encouraged.
Nice one
