Data Transfer using Weaver Relay Service

In this Section, we will learn how to perform a data Transfer between two Fabric networks. We have two business parties:

• Alice is a client of the Fabric network alpha.
• Bob is a client of the Fabric network beta. Alice and Bob engage in the following business process:
• Alice puts new data in alpha inside a given namespace of a given channel.
• Alice contacts Bob telling him new data is available in alpha.
• Bob receives the name of the variable set by Alice.
• Bob queries Fabric network alpha, using Weaver, to get a proof that what Alice said is trustable.
• If the previous step is successful, then Bob stores the same data in beta (inside a given namespace of a given channel).
• Bob acks Alice that he has completed his task.
• Finally, Alice checks that Bob has actually stored the data she put in alpha, using Weaver.

Weaver

Weaver is a platform, a protocol suite, and a set of tools, to enable interoperation for data sharing and asset movements between independent networks built on heterogeneous blockchain, or more generally, distributed ledger, technologies, in a manner that preserves the core blockchain tenets of decentralization and security.
