Permissioned blockchains are being developed and used in Enterprise scenarios in which higher transaction throughput, lower latency, versatile confidentiality and governance models are more important than supporting low trust levels among participants. These Enterprise requirements are not being met adequately by the public and permission-less blockchain ledgers. Enterprise scenarios typically have known actors and the trust level between these actors is very high. This allows for trade-offs between trust levels and transaction throughput, speed, confidentiality and privacy, which in turn enables alternate solutions via permissioned blockchains. Hyperledger Fabric (referred to as ‘Fabric’ in the rest of this article) is the leading permissioned blockchain framework, initially developed by IBM. There are other players in this space, including Multichain, ChainCore and the relatively […]
