Note

End of support notice: Amazon Managed Blockchain will stop accepting new customers on October 29, 2026. Existing customers can continue using Amazon Managed Blockchain until September 29, 2027. After September 29, 2027 you will no longer be able to access Amazon Managed Blockchain. For more information, see Amazon Managed Blockchain availability change.

Amazon Managed Blockchain is a fully managed service for creating and managing blockchain networks using open-source frameworks. Blockchain allows you to build applications where multiple parties can securely and transparently run transactions and share data without the need for a trusted, central authority.

Managed Blockchain supports the Hyperledger Fabric and Ethereum open-source frameworks. Because of fundamental differences between the frameworks, some API actions or data types may only apply in the context of one framework and not the other. For example, actions related to Hyperledger Fabric network members such as CreateMember and DeleteMember don't apply to Ethereum.

The description for each action indicates the framework or frameworks to which it applies. Data types and properties that apply only in the context of a particular framework are similarly indicated.
