Permissioned blockchain technology is enabling multiple organizations to effectively solve cross-organizational problems in a way that has previously not been possible. Hyperledger Fabric provides technology that can be used to establish a permissioned, secure and trusted blockchain network. This capability introduces new dimensions to architecting solutions, where high-availability, data privacy and trust are established through a network that is not centrally controlled. In this talk we will present a Blockchain Solution Reference Architecture, and a set of architecture best practices and decisions that should be considered when designing a Blockchain Network.
