ManagedBlockchain.Client¶A low-level client representing Amazon Managed Blockchain (ManagedBlockchain)
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.

create_foo, and you'd normally invoke the
operation as client.create_foo(**kwargs), if the
create_foo operation can be paginated, you can use the
call client.get_paginator("create_foo").True if the operation can be paginated,
False otherwise.close()¶Closes underlying endpoint connections.
create_member(**kwargs)¶Creates a member within a Managed Blockchain network.
Applies only to Hyperledger Fabric.

[REQUIRED]
The voting rules used by the network to determine if a proposal is approved.
Defines the rules for the network for voting on proposals, such as the percentage of YES votes required for the proposal to be approved and the duration of the proposal. The policy applies to all proposals and is specified when the network is created.
The percentage of votes among all members that must be YES for a proposal to be approved. For example, a ThresholdPercentage value of 50 indicates 50%. The ThresholdComparator determines the precise comparison. If a ThresholdPercentage value of 50 is specified on a network with 10 members, along with a ThresholdComparator value of GREATER_THAN , this indicates that 6 YES votes are required for the proposal to be approved.
The duration from the time that a proposal is created until it expires. If members cast neither the required number of YES votes to approve the proposal nor the number of NO votes required to reject it before the duration expires, the proposal is EXPIRED and ProposalActions are not carried out.

Cloudwatch (dict) --
Parameters for publishing logs to Amazon CloudWatch Logs.
Enabled (boolean) --
Indicates whether logging is enabled.
PeerLogs (dict) --
Configuration properties for a peer node log. Peer node logs contain messages generated when your client submits transaction proposals to peer nodes, requests to join channels, enrolls an admin peer, and lists the chaincode instances on a peer node.
Cloudwatch (dict) --
Parameters for publishing logs to Amazon CloudWatch Logs.
Enabled (boolean) --
Indicates whether logging is enabled.
StateDB (string) --
The state database that the node uses. Values are LevelDB or CouchDB .
Applies only to Hyperledger Fabric.
Status (string) --
The status of the node.
CREATING - The AWS account is in the process of creating a node.AVAILABLE - The node has been created and can participate in the network.UNHEALTHY - The node is impaired and might not function as expected. Amazon Managed Blockchain automatically finds nodes in this state and tries to recover them. If a node is recoverable, it returns to AVAILABLE . Otherwise, it moves to FAILED status.CREATE_FAILED - The AWS account attempted to create a node and creation failed.UPDATING - The node is in the process of being updated.DELETING - The node is in the process of being deleted.DELETED - The node can no longer participate on the network.FAILED - The node is no longer functional, cannot be recovered, and must be deleted.INACCESSIBLE_ENCRYPTION_KEY - The node is impaired and might not function as expected because it cannot access the specified customer managed key in AWS KMS for encryption at rest. Either the KMS key was disabled or deleted, or the grants on the key were revoked. The effect of disabling or deleting a key, or revoking a grant is not immediate. The node resource might take some time to find that the key is inaccessible. When a resource is in this state, we recommend deleting and recreating the resource.CreationDate (datetime) --
The date and time that the node was created.
Tags (dict) --
Tags assigned to the node. Each tag consists of a key and optional value.
For more information about tags, see Tagging Resources in the Amazon Managed Blockchain Ethereum Developer Guide , or Tagging Resources in the Amazon Managed Blockchain Hyperledger Fabric Developer Guide .
Arn (string) --
The Amazon Resource Name (ARN) of the node. For more information about ARNs and their format, see Amazon Resource Names (ARNs) in the AWS General Reference .
KmsKeyArn (string) --
The Amazon Resource Name (ARN) of the customer managed key in AWS Key Management Service (AWS KMS) that the node uses for encryption at rest. If the value of this parameter is "AWS Owned KMS Key" , the node uses an AWS owned KMS key for encryption. The node inherits this parameter from the member that it belongs to.
Applies only to Hyperledger Fabric.
