Tech giant Amazon is launching a blockchain service to help clients develop blockchain networks without incurring the costs of creating their own platform.

Announced Wednesday at Amazon’s re:Invent conference, the Amazon Managed Blockchain platform “is a fully managed service that makes it easy to create and manage scalable blockchain networks.” Users can build platforms using either Hyperledger Fabric or ethereum, though the latter is not yet available.

The new platform is another aspect of Amazon Web Services, Amazon’s cloud computing subsidiary which powers a large number of websites and services, including platforms like Netflix. “Amazon Managed Blockchain eliminates the overhead required to create the network, and automatically scales to meet the demands of thousands of applications running millions of transactions,” the service’s website says.
