Security Model

[WIP] Hyperledger Fabric allows for different organizations and participants in a common network to utilize their own certificate authority, and as a byproduct, implement varying cryptographic algorithms for signing/verifying/identity attestation. This is done through an MSP process running on both the ordering service and channel levels.

Membership service provider (MSP): A set of cryptographic mechanisms and protocols for issuing and validating certificates and identities throughout the blockchain network. Identities issued in the scope of a membership service provider can be evaluated within that membership service provider’s rules validation policies.
