Abstract
Implementations of the present specification provide for management of service keys for consortium blockchain networks within a blockchain-as-a-service (BaaS) platform. Implementations include actions of receiving a request for a service key from a participant in a consortium blockchain network provisioned within the BaaS platform, determining that the participant is authorized for the service key based on a service authorization table that records participant privileges within the consortium blockchain network, providing a key package including an encrypted private key of the service key, and a public key of the service key, and sending the key package to the participant, the participant decrypting the private key of the service key using a public key associated with the participant.
