Chain contract is relayed, and requires to change the state of relaying chain variable；
Step 3: when the state satisfaction for relaying chain variable jumps condition, relaying chain contract is jumped, and exports implementing result；
Step 4: executing monitoring nodes implementing result, after implementing result meets dbjective state, execute node implementing result is defeated
Enter side chain and change corresponding side chain variable, export final result, closes relaying chain contract.
9. according to across the chain distributed service method carried out described in claim 8 based on block chain, which is characterized in that the step
2 specific steps are as follows: the relaying chain contract provides that the monitoring node meets thresholding, when monitoring node meets thresholding, according to
The state of side chain variable changes the state of synchronous change relaying chain variable, makes to relay the state of chain variable and the state of side chain variable
Unanimously.
10. according to across the chain distributed service method carried out described in claim 8 based on block chain, it is characterised in that: in described
Include arbitration mechanism and arbitration term of validity after chain contract, includes arbitration contract in the arbitration mechanism, in arbitration validity period
In limit, if application device or user node have objection to monitoring node to any input that relaying chain contract is sent, by phase
It closes information input and arbitrates contract, final result is determined by arbitration mechanism.
11. according to across the chain distributed service method carried out described in claim 10 based on block chain, it is characterised in that: in described
It include penalty mechanism after chain contract, if the final result shows monitoring, node is wrong, according to the penalty mechanism to described
Monitoring node is punished.
12. according to across the chain distributed service method carried out described in claim 10 based on block chain, it is characterised in that: relaying chain
Contract further includes incentive mechanism, is more than after arbitration validity period, relaying chain contract is saved by incentive mechanism to application device and user
Point carries out disbursement and sattlement.
13. according to across the chain distributed service method carried out described in claim 11 based on block chain, it is characterised in that: relaying chain
Contract further includes contract term of validity, is more than contract term of validity, and relaying chain contract can be automatically closed, if relaying chain contract output
Implementing result do not meet dbjective state, the corresponding overdue responsibility for participating in object will be investigated, execute penalty mechanism.
14. according to across the chain distributed service method carried out described in claim 8 based on block chain, it is characterised in that: across chain
In distributed service, application device can establish controlled variable management system on side chain, assign modification authority to other agencies and save
Point, the application device possess external account and contract account, and specific authorisation step includes:
A: judge whether contract account is authorization initiator, if then continuing to authorize；If not then refusing to authorize, authorization knot
Beam；
B: application device often disposes a contract on side chain, and the address of contract is just indexed in controlled variable management system；
C: the modification authority that application device obtains contract address, contract variable, agent node, agent rule and agent node
Validity period is input in controlled variable management system；
D: authorization is then executed.
