obtaining data to be transmitted, and calculating to obtain a first identifier of the data to be transmitted based on the data to be transmitted;
the first identification is sent to each node in the block chain network through the block chain network, and after the nodes achieve common identification confirmation, the first identification uplink is stored in the block chain network;
transmitting data to be transmitted to a data receiver;
the data receiving party receives the received data and calculates and obtains a second identifier of the received data based on the received data;
transmitting a transmission data verification request to the blockchain network based on the second identifier, and broadcasting the verification request in the blockchain network;
and after receiving the verification broadcast information, the node sends deaf information to a verification request sender, compares a second identifier in the verification request with the first identifier stored in the block chain, and obtains a data transmission quality verification result based on the comparison result.
2. The checking method for the block chain-based data transmission quality according to claim 1, wherein the method obtains the first hash value of the data to be transmitted by calculation, and uses the first hash value obtained by calculation as the identifier of the data to be transmitted; the method obtains the second hash value of the received data through calculation, and takes the second hash value obtained through calculation as the identification of the received data.
3. The method of claim 1, wherein the broadcast mode of the check request in the blockchain network is a full-network broadcast or a directional broadcast.
4. The blockchain-based data transmission quality verification method according to claim 1, wherein for nodes that do not send feedback information, the blockchain network repeatedly sends verification requests or periodically polls the nodes to such nodes until all nodes included in the verification requests receive the verification requests.
5. The block chain based data transmission quality verification method according to claim 1, wherein the method sends the verification result to the verification requester after obtaining the data transmission quality verification result.
6. The block chain-based data transmission quality verification method according to claim 5, wherein the verification requester counts a verification result, wherein the verification result is a ratio of a node which is verified to be correct to a total node; if the ratio is greater than or equal to a preset threshold value, judging that the data transmission quality is qualified; and if the proportion is smaller than the preset threshold value, judging that the data transmission quality is unqualified.
7. The blockchain-based data transmission quality verification method according to claim 1, wherein the method further comprises: deploying a verification program at all nodes in the blockchain network, wherein the verification program is used for verifying transmission data;
the node deployment verification program comprises the following steps:
authenticating a combined machine identity of a distribution deployment file;
the identity authentication process and the result are linked to be stored;
after receiving the deployment requirement, the combined machine encrypts the distributed deployment file, and sends the encrypted deployment file to the node to be installed;
after receiving the encrypted deployment file, the node to be installed decrypts the encrypted deployment file by using a private key carried by the node to be installed, and installs the decrypted file on the node of the node to complete verification program deployment of the node on the blockchain network.
8. A block chain based data transmission quality verification system, the system comprising:
the first calculation unit is used for obtaining data to be transmitted and calculating and obtaining a first identifier of the data to be transmitted based on the data to be transmitted;
the uplink unit is used for sending the first identifier to each node in the block chain network through the block chain network, and storing the first identifier uplink in the block chain network after the nodes achieve the common identifier confirmation;
the transmission unit is used for transmitting the data to be transmitted to a data receiver;
the second calculation unit is used for the data receiving party to receive the received data and calculate and obtain a second identifier of the received data based on the received data;
a sending unit, configured to send a transmission data verification request to the blockchain network based on the second identifier, and broadcast the verification request in the blockchain network;
and the verification unit is used for sending deaf information to the verification request sender after the node receives the verification broadcast information, comparing a second identifier in the verification request with the first identifier stored in the block chain, and acquiring a data transmission quality verification result based on the comparison result.
9. A blockchain based data transmission quality verification apparatus comprising a memory, a processor and a computer program stored in the memory and executable on the processor, characterized in that the processor implements the steps of the blockchain based data transmission quality verification method according to any one of claims 1 to 7 when executing the computer program.
10. A computer-readable storage medium, in which a computer program is stored, which, when being executed by a processor, carries out the steps of the method for checking the quality of block chain based data transmission according to any one of claims 1 to 7.
