Any way you measure it, Change Healthcare is big. In 2017/18, the company processed 14 billion healthcare transactions for claims worth an eye-popping $1 trillion. Behind the scenes, the company’s infrastructure links more than 900,000 healthcare providers and 5,500 hospitals with 2,200 government and commercial payers.
So, when the company decided to test a blockchain, they went big. Starting in January 2018, they have been running a claims-processing network based on Hyperledger Fabric that has shown the capability to handle up to 50 million transactions a day, with throughput up to 550 transactions a second.
And they think it can go even bigger.
