Embodiment approach

[0055] In one embodiment, the proxy node can receive the service request sent by the client, and the service request can include the first signature component and the service processing to be processed; the first signature component here is obtained by the client using the first private key The component is obtained by signing the business data. Secondly, the proxy node can use the second private key to sign the service data. If the signature is successful, it indicates that the client sending the service request is a client that has negotiated a cooperative key pair with the proxy node in advance; in this case, the proxy node can obtain a second signature component after signing with the second private key component , that is, the proxy node can obtain the second signature component; then, the proxy node can integrate the first signature component and the second signature component to obtain target signature information about service data. If the signature fails, it indicate...

Embodiment approach 1

[0089] Embodiment 1: The preset time period includes the penalty start time (that is, the time when the consensus node executes penalty processing) and the penalty end time; then the proxy node can determine the current time to send new transaction data; if the current time is later than the penalty end time , then it can be determined that the current state of the agent node is a non-punishment state where punishment has ended; otherwise, it is determined that the current state of the agent node is still in a punished state. Embodiment 2: The preset time period is a penalty period, and the agent node can determine the historical time when the penalty notice is received, and the current time when new transaction data is to be sent; then calculate the interval between the current time and the historical time , if the interval time length is longer than the penalty time length, it can be determined that the current state of the agent node is a non-punishment state where punishmen...

Abstract

The embodiment of the invention discloses a data processing method and device, computer equipment and a medium, and the method comprises the steps: obtaining target signature information related to business data, and enabling an agent node and a client to carry out the cooperative signature of the business data to obtain the target signature information; obtaining a client certificate of a clientand a node certificate of a proxy node, wherein the node certificate and the client certificate contain the same shared public key, and the shared public key is used for verifying the validity of thetarget signature information; adopting the business data, the target signature information, the node certificate and the client certificate to generate transaction data; and broadcasting the transaction data to a consensus node in the blockchain network so that the consensus node performs consensus on the transaction data, and adding the transaction data to a blockchain of the blockchain network after the transaction data passes the consensus. By adopting the embodiment of the invention, the reliability and safety of data uploading can be effectively improved.

Description

technical field [0001] The present invention relates to the field of Internet technology, specifically to the field of communication computing technology, and in particular to a data processing method based on a blockchain network, a data processing device, a computer device, and a computer storage medium. Background technique [0002] With the development of Internet technology, the blockchain network has received widespread attention due to its safe and reliable performance. More and more individuals or enterprises choose to use the client to store business data in the blockchain of the blockchain network to prevent the business data from being stolen by malicious users. At present, when the client wants to upload business data to the blockchain network, it usually first signs the business data with the private key of the client, and then sends the signed business data to the consensus node in the blockchain network; The consensus node uses the client's public key to veri...
