IT giants IBM and Oracle are working to make their blockchains communicate with each other. Mark Rakhmilevich, Oracle's senior director of blockchain product management, said at the Hyperledger Global Forum last week that interoperability work is being done on a blockchain built using Fabric. Rakhmilevich said Oracle has conducted comprehensive tests with IBM and SAP. The three parties have basically tested Fabric across the network. So if someone says they want to run the network on Oracle, but some of its members want to work on IBM, we can show them a tested and certified process. In a way, this is to allow blockchain nodes to run on the cloud of IBM and Oracle at the same time, but it also opens the door for corporate alliances connecting the two platforms.
