Abstract: Embodiments of the present disclosure relate to a service flow system and a service data processing method and apparatus. The system can include a management server, a distributed storage cluster and a block chain alliance network connected by a network, the block chain alliance network including a consensus node and at least one participant node. Through unified management of a management server, off-chain data is stored in a distributed storage cluster, then participants of each phase are defined for different projects, and the participants of the same phase of the same project share the same on-chain and off-chain data. Therefore, credible access of the participants to block chain data is solved, dynamic customizable phase management of the projects in a service flow is supported, the on-chain data and participants of each phase are strictly divided and managed, and associated management of on-chain and off-chain service flow data is also supported.
