Amazon Managed Blockchain now supports customer-managed customer master keys (CMKs) for Hyperledger Fabric networks. Customers can encrypt new member-specific resources using their own CMK. These CMKs are declared in AWS Key Management Service (KMS) and used by Amazon Managed Blockchain. Each member can use their own CMK and manage it according to their security policy.
Amazon Managed Blockchain is a fully managed service that allows you to join public networks or set up and manage scalable private networks with just a few clicks. Amazon Managed Blockchain eliminates the overhead required to create the network or to join a public network, and it automatically scales to meet the demands of thousands of applications running millions of transactions. Once your network is up and running, Amazon Managed Blockchain makes it easy to manage and maintain your blockchain network. It manages your certificates and lets you easily invite new members to join the network.
To learn more about these keys and how to configure them, see the Data Protection topic in the Hyperledger Fabric Developer Guide.
