Exploiting smart contracts in PBFT-based blockchains: A case study in medical prescription system

Smart contracts allow application developers to automate business processes through a decentralized computation architecture. Contemporary blockchain platforms such as Ethereum and Hyperledger Fabric offer support for smart consensus mechanisms Proof-of-Work (PoW) or other types of transaction validation ordering services. This article exploits in the Byzantine Fault Tolerant (BFT) platforms. In particular, we explore Tendermint Besu, BFT platforms, apply them e-prescription case study evaluate their effectiveness. We adopt Besu this research, given that both are BFT-based blockchains. Also, it is noteworthy not well established widely adopted yet. Our empirically evaluates performance using medical prescription compares results with Ethereum, PoW blockchain. demonstrate efficient multi-stakeholder applications supply chains. To best our knowledge, first investigating implementation Besu.
