Key Concepts Introduction Hyperledger Fabric Functionalities Membership Service Provider instances allowing for crypto materials to be derived from different certificate authorities See the Ledger topic for a deeper dive on the databases, storage structure, and “query-ability transaction ordering into blocks for distribution. Each of the four organizations has a preferred Certificate Authority. Creating the Network Let’s start at the beginning by creating the basis for the network:

UI Components When opening bug reports or sending Default: '' The full path to an SSL/TLS certificate file. NotebookApp.client_ca : Unicode Default: '' The full path to a certificate authority certificate for SSL/TLS client authentication. NotebookApp for encrypted communication When using a password, it is a good idea to also use SSL with a web certificate, so that your hashed password is not sent unencrypted by your browser.
