Startup Stronghold is launching USD Anchor, which will run on the rails of the Stellar blockchain and use its consensus mechanism to verify transactions, but will be backed one-for-one with US dollars held at a Nevada-chartered trust company called Prime Trust which will have proper FDIC insurance. IBM is partnered with Stronghold and will explore further use cases of its token with financial institution clients.  Stronghold also represents a further extension of the IBM and Stellar partnerships.
