This system is a part of the Waltonchain Cross-chain Project. It realizes endorsement of child chain data to the parent chain. In this system, the ecosystem’s JMN (Judge Master Nodes) and SMN (Super Master Nodes) perform management through voting.

• The reward transferred by the child chain owner to the corresponding endorsement contract serves as the endorsement reward
• SMN can endorse child chain data to the parent chain through the SMN System and get the endorsement reward
• JMN manage JMN, SMN and endorsement contract templates
• SMN can add child chains and child chain endorsements

• Gwtc node: blockchain node
• SMN System: Endorsement operations can be carried out in this system and corresponding rewards can be obtained.
• Management System: permission management (including JMN, SMN management), endorsement contract template management, child chain management, endorsement management
• Data Verification System: verification of the endorsed data

Note: In case of multiple votes, more than half equals passed.
