Connected Blockchain Federations for Sharing Electronic Health Records

With the growing utility of blockchain technology, desire for reciprocal interactions among different blockchains is growing. However, most operational networks currently operate in a standalone setting. This fragmentation form isolated creates interoperability difficulties, inhibiting adoption various ecosystems. Interoperability key factor healthcare domain sharing EHRs patients registered independent networks. Each network could have its own rules and regulations, obstructing exchange improving diagnosis treatments. Examples include being treated by providers countries or regions, within one country but with set per state emirate. By contrast, federation can provide better communication service to stakeholders healthcare. Thus, solutions facilitating inter-blockchain such are needed. this possibility has not been fully explored, further investigations still conducted. Hence, present study proposes transaction-based smart contract triggering system communication, enabling EHR blockchains. We use local global contracts that will be executed once transaction created blockchain. Local used blockchain, whereas The experimental setup conducted using Hyperledger Fabric platform. Inter-blockchain between two fabric through Cactus health setup. To best our knowledge, first implement an model domain.
