Blockchain is a decentralized, trustless protocol that combines transparency, immutability, and consensus properties to enable secure, pseudo-anonymous transactions. Smart contracts are built atop a blockchain to support on-chain storage and enable Decentralized Apps (DApps) to interact with the blockchain programatically. Programmable blockchains have generated interest in the healthcare domain as a potential solution to resolve key challenges, such as gapped communications, inefficient clinical report delivery, and fragmented health records. This paper provides evaluation metrics to assess blockchain-based DApps in terms of their feasibility, intended capability, and compliance in the healthcare domain.
