ManagedBlockchain class

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 do not 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.

Constructors

ManagedBlockchain({required String region, AwsClientCredentials? credentials, AwsClientCredentialsProvider? credentialsProvider, Client? client, String? endpointUrl})

Properties

hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

close() → void
Closes the internal HTTP client if none was provided at creation. If a client was passed as a constructor argument, this becomes a noop.
createMember({required String invitationId, required MemberConfiguration memberConfiguration, required String networkId, String? clientRequestToken}) → Future<CreateMemberOutput>
Creates a member within a Managed Blockchain network.
createNetwork({required Framework framework, required String frameworkVersion, required MemberConfiguration memberConfiguration, required String name, required VotingPolicy votingPolicy, String? clientRequestToken, String? description, NetworkFrameworkConfiguration? frameworkConfiguration}) → Future<CreateNetworkOutput>
Creates a new blockchain network using Amazon Managed Blockchain.
createNode({required String networkId, required NodeConfiguration nodeConfiguration, String? clientRequestToken, String? memberId}) → Future<CreateNodeOutput>
Creates a node on the specified blockchain network.
createProposal({required ProposalActions actions, required String memberId, required String networkId, String? clientRequestToken, String? description}) → Future<CreateProposalOutput>
Creates a proposal for a change to the network that other members of the network can vote on, for example, a proposal to add a new member to the network. Any member can create a proposal.
deleteMember({required String memberId, required String networkId}) → Future<void>
Deletes a member. Deleting a member removes the member and all associated resources from the network. DeleteMember can only be called for a specified MemberId if the principal performing the action is associated with the AWS account that owns the member. In all other cases, the DeleteMember action is carried out as the result of an approved proposal to remove a member. If MemberId is the last member in a network specified by the last AWS account, the network is deleted also.
deleteNode({required String networkId, required String nodeId, String? memberId}) → Future<void>
Deletes a node that your AWS account owns. All data on the node is lost and cannot be recovered.
getMember({required String memberId, required String networkId}) → Future<GetMemberOutput>
Returns detailed information about a member.
getNetwork({required String networkId}) → Future<GetNetworkOutput>
Returns detailed information about a network.
getNode({required String networkId, required String nodeId, String? memberId}) → Future<GetNodeOutput>
Returns detailed information about a node.
getProposal({required String networkId, required String proposalId}) → Future<GetProposalOutput>
Returns detailed information about a proposal.
listInvitations({int? maxResults, String? nextToken}) → Future<ListInvitationsOutput>
Returns a list of all invitations for the current AWS account.
listMembers({required String networkId, bool? isOwned, int? maxResults, String? name, String? nextToken, MemberStatus? status}) → Future<ListMembersOutput>
Returns a list of the members in a network and properties of their configurations.
listNetworks({Framework? framework, int? maxResults, String? name, String? nextToken, NetworkStatus? status}) → Future<ListNetworksOutput>
Returns information about the networks in which the current AWS account participates.
listNodes({required String networkId, int? maxResults, String? memberId, String? nextToken, NodeStatus? status}) → Future<ListNodesOutput>
Returns information about the nodes within a network.
listProposals({required String networkId, int? maxResults, String? nextToken}) → Future<ListProposalsOutput>
Returns a list of proposals for the network.
listProposalVotes({required String networkId, required String proposalId, int? maxResults, String? nextToken}) → Future<ListProposalVotesOutput>
Returns the list of votes for a specified proposal, including the value of each vote and the unique identifier of the member that cast the vote.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
rejectInvitation({required String invitationId}) → Future<void>
Rejects an invitation to join a network. This action can be called by a principal in an AWS account that has received an invitation to create a member and join a network.
toString() → String
A string representation of this object.
inherited
updateMember({required String memberId, required String networkId, MemberLogPublishingConfiguration? logPublishingConfiguration}) → Future<void>
Updates a member configuration with new parameters.
updateNode({required String networkId, required String nodeId, NodeLogPublishingConfiguration? logPublishingConfiguration, String? memberId}) → Future<void>
Updates a node configuration with new parameters.
voteOnProposal({required String networkId, required String proposalId, required VoteValue vote, required String voterMemberId}) → Future<void>
Casts a vote for a specified ProposalId on behalf of a member. The member to vote as, specified by VoterMemberId, must be in the same AWS account as the principal that calls the action.

Operators

operator ==(Object other) → bool
The equality operator.
