Specifically, the voting result does not include the voting information of which users specifically belong to, and all users on the blockchain can know the result, so that the voting result can be the authority of the trusted node participating in the blockchain to obtain the voting result.
The verifying whether the second user is a trusted user comprises: verifying whether the identity information of the second user meets the identity information of a preset credible condition; and when the identity information of the second user meets the identity information of a preset credible condition, judging that the second user is a credible user.
Specifically, the user whose user identity information that the second user has successfully registered in the blockchain network in advance meets the preset trusted condition may be verified, if the preset trusted condition may be that a preset trusted value is greater than a preset threshold value, the user may be determined as a trusted user, the trusted value may be a preset initial value of the user who has successfully registered in the blockchain network, and then the value may be added or subtracted according to a preset behavior of the user account, for example, the preset value is subtracted from the preset malicious behavior data.

Each decryption algorithm corresponds to an identifier.
Step S2052 is to decrypt the received encrypted digital signature according to the target decryption algorithm to obtain a digital signature.
Specifically, the identifiers corresponding to a pair of decryption algorithms and encryption algorithms are the same, for example, the same identifier corresponds to the EIGmamal encryption algorithm and the EIGmamal decryption algorithm, and the same identifier corresponds to the elliptic curve encryption algorithm and the elliptic curve decryption algorithm. Therefore, when the first blockchain node needs to decrypt, the corresponding decryption algorithm can be selected based on the received identifier to decrypt.
Because various cryptographic techniques can be used in the field of block chain technology to ensure security, a plurality of decryption algorithms can be stored in a first block chain node in advance, each decryption algorithm corresponds to an identifier, a plurality of encryption algorithms are stored in a second block chain node, each encryption algorithm corresponds to one decryption algorithm in the first block chain node, before encryption is performed on a second block chain node, an encryption algorithm is selected from the plurality of prestored encryption algorithms through a random algorithm, after selection is determined, the identifier corresponding to the selected encryption algorithm can be sent to the first block chain node, and when the first block chain node needs to decrypt, the corresponding decryption algorithm can be selected to decrypt based on the received identifier, so that randomness of encryption and decryption is increased, and the security of the user identity in the voting process is further improved.
And step S206, if the identity information of any node in the second block chain nodes with the authority is matched, judging that the corresponding voting money transfer is valid.
Specifically, when the identity information of the authenticated user is the same as any one of the identity information of the second blockchain node having the authority, the voting choice is determined to be valid.
Step S207, determining a voting result according to the judged valid voting transfer money, and broadcasting the voting result in the block chain so that the node in the block chain stores the voting result;
specifically, when the voting result is determined according to the determined valid voting data, since the block chain is a distributed network system, it has a mechanism characteristic that each node can efficiently achieve consensus on the validity of the block data in a decentralized system with highly dispersed decision weights, that is, the consensus mechanism of the block chain. Therefore, the voting result is broadcasted in the block chain, so that the nodes in the block chain are stored, the evidence can be stored, and the characteristics of non-falsification are provided.
Step S208, when any block chain node storing the voting process receives the transaction information of the first user accessing the block chain network, verifying the access right of the first user according to an intelligent contract of a pre-deployed access control strategy, and allowing the first user to acquire the transaction information when the access right of the first user is verified;
step S209, when any block chain node storing the voting result receives a transaction result in the second user access block chain network, verifying whether the second user is a trusted node, and when the second user is a trusted user, allowing the second user to access the voting result.
Specifically, the points from step S208 to step S209 that are the same as or similar to the points from step S106 to step S107 can be referred to the related descriptions from step S106 to step S107, and are not repeated herein.
According to the embodiment of the application, the digital signature corresponding to the correlation of the voting transfer currency is associated with the voting transfer currency through the second block chain node, the voting transfer currency after the digital signature is associated is transferred to the account corresponding to any voting option, and after the voting transfer currency including the digital signature is received through the first block chain node, whether the data signature is matched with the identity information of any node in the second block chain node with the authority is verified. If the identity information of the second block chain node with the authority is matched with the identity information of any node in the second block chain node with the authority, the corresponding voting transfer coin is judged to be valid after the digital signature is verified successfully, the voting data security is guaranteed, and finally the voting result is broadcasted in the block chain, so that the voting of the legal voting user is guaranteed to be valid voting, and the voting data security and the fairness in the creditor conference are further guaranteed.
