Case Study: Optum achieves 50M claims transactions/day and real-time claims transparency with Hyperledger Fabric

Change Healthcare using Hyperledger Fabric to improve claims lifecycle throughput and transparency

Optum, a large healthcare technology and network operator connecting providers, hospitals, and payers, faced the challenge of proving that blockchain could handle real-world claims volumes and deliver transparent, auditable claim lifecycles. Seeking a vendor-neutral, open-source solution that thousands of providers and competing payers could adopt, Optum evaluated platforms and selected Hyperledger — specifically Hyperledger Fabric — to test production-scale processing.

Using Hyperledger Fabric, the team built a blockchain-enabled claims-processing network in a matter of months and ran it in parallel with existing systems; the test network processed up to 50 million transactions per day with throughput reaching 550 transactions per second. Hyperledger enabled real-time APIs and immutable audit trails for claims, reducing reconciliation effort, increasing transparency across participants, and demonstrating enterprise-scale blockchain performance for revenue-cycle management.
