Introduction to Chang'an chain node certificate, role and authority management

Certificate management system

ChainMaker There are three types of certificates used in blockchain networks ：

CA certificate

1. Subdivide into roots CA certificate 、 middle CA certificate 、 Since the signing CA certificate , The other two types of certificates use CA Certificate signature generation .
2. One for each organization CA certificate . adopt chainmaker-cryptogen Generate .
3. All node certificates and user certificates of the organization are from this CA Certificate issuance generates .

Node Certificate

1. Subdivide into consensus nodes 、 Synchronization node 、 Certificates used by light nodes . The certificate types of the synchronization node and the light node are the same .
2. Each organization has at least one consensus node , You can also deploy multiple .
3. Each organization can have several synchronization and light nodes , You can't deploy .
4. Each node will have one node TLS Certificates and a node SIGN certificate
5. node TLS Certificates are used to establish with clients tls link , Use CA The certificate is issued to obtain
6. use
