Install the necessary Python packages for working with blockchain and AWS. You can do this by running the following commands:
pip install blockchain
pip install boto3Import the necessary modules for working with blockchain and AWS in your Python script. You can do this by adding the following lines of code at the beginning of your script:
import blockchain
import boto3Connect to the AWS blockchain service by creating an instance of the boto3 client and providing your AWS access key and secret key. You can do this by adding the following lines of code to your script:
client = boto3.client('blockchain',
aws_access_key_id='YOUR_ACCESS_KEY',
aws_secret_access_key='YOUR_SECRET_KEY')Create a blockchain network on AWS by calling the create_network method of the client object and providing the necessary parameters such as the network name, edition, and framework. You can do this by adding the following lines of code to your script:
response = client.create_network(
Name='my-blockchain-network',
Edition='STANDARD',
Framework='HYPERLEDGER_FABRIC',
Description='My blockchain network for a hospital health information system',
FrameworkVersion='1.4.8',
VotingPolicy={
'ApprovalThresholdPolicy': {
'ThresholdPercentage': 50,
'ProposalDurationInHours': 24
}
},
MemberConfiguration={
'Name': 'HospitalMember',
'Description': 'A member for the hospital health information system',
'FrameworkConfiguration': {
'Fabric': {
'AdminUsername': 'admin',
'AdminPassword': 'adminpw'
}
}
}
)Create a blockchain network member on AWS by calling the create_member method of the client object and providing the necessary parameters such as the network id, member name, and role. You can do this by adding the following lines of code to your script:
response = client.create_member(
NetworkId='my-blockchain-network-id',
MemberName='my-blockchain-network-member',
Role='NETWORK_MEMBER',
Description='A member of my blockchain network for the hospital health information system'
)Create a blockchain network invitation on AWS by calling the create_invitation method of the client object and providing the necessary parameters such as the network id, member id, and role. You can do this by adding the following lines of code to your script:
response = client.create_invitation(
NetworkId='my-blockchain-network-id',
MemberId='my-blockchain-network-member-id',
Role='NETWORK_MEMBER'
)Accept the blockchain network invitation on AWS by calling the accept_invitation method of the client object and providing the necessary parameters such as the invitation id and network id.
response = client.accept_invitation(
NetworkId='my-blockchain-network-id',
InvitationId='my-blockchain-network-invitation-id',
