I viewed the US State Dept's Blockchain Forum yesterday. 1 use case: IDs for refugees through storing their data securely on the blockchain. How can this happen if refugees don't have tokens or coins

Ok let me clarify one thing... look at blockchain technology as a decentralized hub that hosts peer to peer transactions and record them in the form of a ledger without intervention from any 3rd parties. It can't be regulated and it can't be controlled by any one party. You don't need coins or tokens to be part of this... tokens are usually used by companies / startups for fundraising their business idea or concept through initial coin offering whereby they offer incentive or reward in return of their people investing in money into their venture. Those tokens can then be transformed into coins which investors could use to purchase this company product / service and if campaign successful and the startup delivers on its promises, the coin will hit the exchange and start gaining value as adopters start to trade them... But... blockchain tech is much more than this and it can be employed without association to any coin or token for example to build smart contracts to execute 2 parties agreement automatically through an algorithm without any manual intervention. Same goes to keeping records and many other applications... hope this is clear now?
Estonia is already using it with their e-citizenship program. You don't have to have tokens in order for blockchain to work.
