     Observations 
     •  Health Records are an important part of the ecosystem 
     •  Many block-chain pilots and proof of concepts occurred over the last 2 years.   Waiting for an 
        authoritative source or public entity willing to publish valid claims/information to a node.
     •  Vendors have stopped talking about blockchain  - now focusing on value add of their service to Health 
        IT environment  
     •  Early success using Distributed Ledger Technology – private chains  within and enterprise to extend 
        existing SOA/SOAP based services – enables agile microservices  that support Big DATA - AI type 
        services (HHS Procurement is an example)
     •  There are few flavors of blockchain taking most of the market with input support by major companies.   
        (Etherum and Hyperledger in particular)
     •  Slow progress for reward program – earn credit/coins -  stood up to support patient participation in a 
        PHR or Research clinical trial
