Upon detection of the anchoring result, the mineworker character miA vote referencing the anchor task can be created and the voting results sent to the anchor task, and only valid votes can be accepted.
In this embodiment, defining effective voting needs to satisfy the following conditions: the voter must be the miner of the current block; the vote can only be yes or no; each block can only have one vote; the voting time must be before the notarization phase begins. The formula is as follows:
wherein, Account thereincoinbaseTxRepresenting the submitter account of the current block, and checking the coinbase transaction through an intelligent contract to obtain; "yes" or "no" stands for iRole m of minerVoting conclusion on the anchoring result, "yes" represents positive anchoring result, and "no" represents negative anchoring result; in a block, only one is validSelecting a vote; after the arrival of NotarizeTime, the number of votes is counted, and the anchor task succeeds if it receives no less than 50% of the "yes" votes, otherwise it fails.
In the settlement stage, if the notarization stage is completed, the anchoring task is finished, at the moment, the settlement stage is entered for settlement, and the settlement stage settles the roles participating in the anchoring task according to whether the anchoring task is completed or not.
In this embodiment, the settlement in the settlement stage can preferably perform corresponding settlement according to the completion status of the anchor task, thereby preferably realizing the reward distribution for the role participating in the anchor task.
Wherein, the status of the completed anchor task comprises success and failure, and the status of the uncompleted anchor task comprises data collection phase failure, auction phase failure and report phase failure.
For successfully completed anchor tasks, during the settlement phase, the anchor task receives the user role uiPaid fee and direct to agent role aiAnd all miners' roles m for casting "yes" ticketsiPayment, facilitator role siThe remaining fee is charged.
For anchor tasks that fail to complete, the anchor task rolls back to user role u during the settlement phaseiPaid fee and charge agent role aiPaying the deposit as a penalty and allocating the collected deposit to the facilitator's character s in a proportioniAnd the miners casting no ticketsi。
For incomplete anchor tasks that fail the collection phase, there is no user role uiTherefore, the fee settlement is not required in the settlement stage.
For incomplete anchoring tasks that fail in the auction phase, i.e. agentless role aiParticipate in the auction, so in the settlement stage, only the role u of the user needs to be returnediThe fee paid.
For incomplete anchor tasks that fail the reporting phase,i.e. the winning agent character aiAnchoring of data is not performed, so that in the settlement phase, the user role u is returnediPaid fee and charge agent role aiPaid deposit as facilitator role siA reward of (1).
