Instance election consensus-based transaction uplink error prevention method and device and electronic equipment

Abstract

The embodiment of the invention provides a transaction chaining mistake proofing method based on instance election consensus, which comprises the following steps: creating a plurality of instances sharing the same block address for a service provider, and independently performing contract notarization transaction on each instance and a service demander to generate a transaction log which comprisestransaction content and a signature instruction with a changeable state, synchronizing the transaction log of the current transaction of the current instance to other instances, keeping the multipleinstances consistent through log synchronization, judging whether a signature instruction is in an initial state or not in combination with the transaction log synchronized among the instances, and signing the transaction content by utilizing a digital certificate in the signature instruction based on a judgment result. According to the embodiment of the invention, the abnormal condition or attackthat one signature instruction is repeatedly used by different instances can be recognized so as to prevent repeated use, and the leader instance generated by election is used as the access node of the blockchain to uplink the signed transaction content, so that the uplink of the transaction is controlled, and the safety and credibility of a multi-instance transaction mode are improved.

Description

technical field [0001] The present application relates to the field of the Internet, and in particular to a method, device and electronic device for error-proofing transaction on-chain based on instance election consensus. Background technique [0002] Empowering notarization refers to endowing the corresponding documents of the transaction contract with enforcement effect. Enforcement notarized documents not only have authenticity and legality, but also give enforcement effect, which is the meaning of "enforcement". [0003] In the process of concluding a contract transaction, the business provider and the business demander notarize the contract through the intermediary of the notary office. In this way, the business provider, the business demander and even the guarantor should perform the due obligations and refuse to perform or refuse to perform At that time, one of the parties may apply to the notary office for the issuance of an enforcement certificate with the notariz...

Problems solved by technology

[0004] At present, although the concept of online notarization has been proposed in the industry, there are few implementation plans. This is because the current business systems are still mostly centralized systems. For the transaction contract signed by notarization, in the strengthening stage, the transaction contract temporarily extracted from the centralized system is difficult to convince other business parties that this is the transaction content when the contract is signed

[0005]On the other hand, for business providers such as banks, multiple business lines often carry out business and sign contracts with many customers at the same time. If a decentralized system is used To provide storage services, it is necessary to sign the contract to ensure the authenticity of the contract signer. However, if each business line has its own digital certificate and private key, the blockchain is difficult to manage (for example, node verification on the chain) Its identity needs to be verified one by one by using multiple public keys of the bank, and each verification fails to finally determine the identity verification failure), if each business line uses the same private key to generate signature instructions to sign the transaction content, and then If the information is uploaded to the chain, there may be security issues and errors where a signature instruction is used multiple times.
