Data are transmitted to other nodes in block chain network.First node is scored by the private key of first node second simultaneously
Cryptographic Hash encrypted, signed, other nodes obtained signature being also sent in block chain network 101.
S403: it receives each second node is sent described first and is verified message, wherein when a second node
Determine that second scoring exists from the first node and second scoring according to the signature and second scoring
When being not tampered with during transmission, sends described first and be verified message.
Wherein, each of block chain network 101 node is all stored with the private key and other nodes of own node
Public key, when second node receives data in the block head mentioned in signature and the second scoring and above-mentioned steps S4022,
Second scoring is subjected to Hash calculation, the result being calculated is compared with the Merkle root in block head, is tied when comparing
When fruit is consistent, illustrate that the second scoring is not tampered in transmission process.Further, the first node that second node stores
Public key is decoded the signature received, and the result of decryption is compared with the cryptographic Hash of the second scoring, works as comparison result
When consistent, determine that scoring derives from first node.When second node determines that the second scoring is not tampered with, and score from the
When one node, first is sent to first node and other second nodes and is verified message.Each second node is held
The above-mentioned verification operation of row, and transmit verification result to first node and other second nodes.
In some instances, after having carried out above-mentioned two steps card, a second node to first node and its
His second node sends first and is verified before message, further includes steps of
S4031: each second node saves the average score of media content, and each second node is logical in transmission first verifying
It crosses before message, further determines that the difference of second scoring and the average score, when the difference is no more than threshold value,
Execute the operation that the transmission described first is verified message.
Second node scores according to the first of the media content saved in the block chain 110 of self maintained and determines media content
Average score, further verifying second scoring validity.When the second scoring and the difference of the average score are no more than threshold
It when value, determines that the second scoring is effective, otherwise determines that the second scoring is invalid.When further determining that above-mentioned second scoring is effective,
It sends above-mentioned first and is verified message.
S404: for any node in the multiple node, when the first quantity for being verified message received reaches
When to threshold value, second scoring is saved.
Each second node can send first to first node after being verified and be verified message, when first node receives
To the first quantity for being verified message reach threshold value when, by second scoring save.Wherein, the threshold value can be the second section
The quantity of point just saves the second scoring that is, when the verification result of each second node received is to be verified.Institute
Stating threshold value may be 51% or other values.A second node can also receive testing for other second node feedbacks simultaneously
