What blockchain interoperability means for enterprise applications

Start with the business process

A connection between blockchain environments is useful only if it helps an application do its job. Map where information or a transaction needs to move, who needs to use it, and what each party must be able to trust. Supply-chain traceability, credentials and payments present different requirements, so assess interoperability against a specific workflow rather than as a standalone feature.

Look beyond moving data

Enterprise applications may need to handle identity and credentials as well as transaction information. Blockchain-related work in this area includes verifiable credentials, decentralized identity and DID concepts. If these matter to your application, ask how each participating environment handles identity and how people or organizations will use credentials across the workflow.

Evaluate payments in their full context

A payment workflow may span digital-ledger or cryptocurrency technology and fiat-payment environments. Define which parts of that workflow an application needs to support, then examine how the proposed architecture handles them. Rohan Hall led technology architecture at RocketFuel Blockchain, where his work included payment technologies across those environments.

Make trust and governance part of the decision

Interoperability should be evaluated alongside evidence, transparency, assurance, standards and governance. Enterprise architects can use those considerations to compare approaches and explain the trade-offs to business leaders. Rohan Hall has built and led technology for blockchain interoperability and scalable blockchain applications; the practical decision still depends on the workflow and requirements of the organization adopting it.

Frequently asked questions

Is interoperability the same as supply-chain traceability?

No. Traceability is a business use case. Interoperability concerns how an application works across disconnected blockchain environments that may be involved in that use case.

Where do decentralized identity and verifiable credentials fit?

They are relevant when a workflow needs to handle identity or credentials across participants. Assess their role in the specific application rather than assuming every interoperability project needs them.

What should leaders ask before choosing an approach?

Ask which workflow it serves, which environments must participate, how identity or payments fit, and what evidence, standards and governance the organization needs to rely on it.
