Description
Technical Field
The application relates to the technical field of block chains, and discloses a method and a system for trading securities type general certificates and a storage medium.
Background
The blockchain technology is a brand new distributed infrastructure and computing mode that uses blockchain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to secure data transmission and access, and uses intelligent contracts composed of automated script codes to program and manipulate data. The block chain technology solves the trust problem in the traditional intermediary mechanism by the decentralization characteristic of the block chain technology, and provides effective technical support for the circulation of electronic money. Accordingly, various forms of digital certificates (tokens), referred to simply as tokens, have been generated based on blockchain technology, which can be circulated as virtual currency to purchase specific items. With the increasing development of blockchain technology, more and more electronic applications are beginning to gradually use certificates for transactions.
The general certificate can represent all digital rights and interests certificates, from identity cards to academic diplomas, from currency to bills, from keys, tickets to points and cards, from stocks to bonds, and all human society rights and interests certificates such as accounts, ownership, qualification and certificates can be represented by the general certificate.
Therefore, the higher the decentralized degree of the block chain is, the more the authenticity and traceability of the certified transaction can be ensured. Although the public link has a higher degree of consensus than the alliance link, the public link requires the certificate issuing party to disclose all data, which is not favorable for the circulation and issuing of the securities type certificates and even damages the information security of the certificate issuing party. Therefore, there is a need to develop a method for securities-type negotiable transaction that can ensure the information security of the negotiable issuer while maintaining the authenticity of the negotiable certificate.

Detailed description of the preferred embodiments
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
The embodiment of the application provides a securities type general evidence trading method, as shown in fig. 1, comprising the following steps:
and 101, initiating a certification transaction on the alliance chain by the node on the alliance chain.
The certification-ready negotiable encrypted digital rights proof has three basic characteristics: one is digital rights attestation. The certificate must be a digital form of rights voucher which must represent a right, an inherent and inherent value. The general certificate can represent all digital rights and interests certificates, from identity cards to academic diplomas, from currency to bills, from keys, tickets to points and cards, from stocks to bonds, and all human society rights and interests certificates such as accounts, ownership, qualification and certificates can be represented by the general certificate. The second is encryption. The authenticity, tamper resistance, privacy protection and other capabilities of the certificate are guaranteed by cryptography. Each pass is a cryptographically protected right. This protection is more robust and reliable. And thirdly, the circulation is realized. The certificate must be able to flow in a network so that it can be verified anytime and anywhere.
In the embodiment of the application, the general certificate mainly refers to a security type general certificate, and the general certificate has the characteristics of low cost, strong liquidity, high transparency and wide financing range.
And 102, recording the certification transaction by the node, and mapping the certification to the public chain.
In the embodiment of the present application, an account dedicated to initiating a pass-through transaction for a federation chain exists on a public chain, and the account is marked as a service node. The method for creating the service node specifically comprises the following steps: after a user creates an account in the alliance chain, an account is created in the public chain in a mapping mode. After the evidence-passing transaction initiated by the account of the alliance chain is approved, the evidence-passing transaction is mapped to the service node through the cross-chain middleware, and then the service node initiates the evidence-passing transaction on the public chain.
And 103, inquiring the result of the certification transaction on the public link by the alliance link.
And 104, when the inquired result indicates that the certification transaction on the alliance is successful, the node broadcasts the certification transaction on the alliance chain and writes the inquired result into the block.
In the embodiment of the application, after the public link initiates the certification transaction, the alliance link can regularly check the certification transaction result on the public link. And if the certification-passing transaction on the public link is successful, the alliance link determines that the certification-passing transaction on the alliance link is successful. And if the certification-based transaction on the public link fails, the alliance link determines that the certification-based transaction on the alliance link fails.
Specifically, a time lock is generated in the federation chain for the initiated forensic transaction. And the alliance chain inquires the result of the certification transaction on the public chain in the time lock range. If the certification transaction on the public link is successful, the time lock is released in the alliance link, and the certification transaction initiated on the alliance link is broadcasted. And if the certification-passing transaction on the public chain fails, canceling the certification-passing transaction initiated on the alliance chain. For example, when initiating a pass-through transaction a, a 24 hour time lock is set for transaction a, at which time transaction a is not broadcast to other nodes of the federation chain for the moment. Meanwhile, in the time lock: if a credential is taken within 24 hours that the transaction was successful on the federation chain, the time lock is released in the federation chain and transaction A is broadcast. If no voucher is taken for successful transaction on the public link within 24 hours, transaction A is considered to have failed and transaction A is cancelled.
In the embodiment of the application, if the evidence-based transaction on the alliance chain is successful, the accounting node generates a transaction success identifier and writes the transaction success identifier and the evidence-based transaction into the same block. And if the evidence-passing transaction on the alliance chain is determined to fail, the accounting node generates a transaction failure identifier and writes the transaction failure identifier into the block.
In the above method, the federation chain maps the certificate into the public chain because the consensus degree of the federation chain is low. The public link initiates the certification transaction, only when the certification transaction on the public link is successful and reaches the consensus, the alliance link finally determines the transaction success, and because the public link has a high consensus degree, the authenticity and traceability of the certification transaction can be ensured. Therefore, in the embodiment of the application, the alliance chain and the public chain are combined for use, so that the information security of the certificate issuing party is ensured, and the authenticity and traceability of the certificate transaction are ensured.
In addition, securities-like certificates usually relate to stocks, bonds and the like, and are used for preventing people from maliciously destroying the circulation and distribution of certificates, such as operating the certificate market, maliciously buying vacancies and the like. In this embodiment of the present application, any node in a federation chain receives public-link access request information sent by a user, where the access request information includes: user identity information. And the receiving node of the inbound request information initiates a transaction request by utilizing the inbound request information. Each node in the federation chain verifies the user identity information.
When the verification of the user identity information by each node in the alliance chain is passed, the alliance chain distributes corresponding public chain addresses, private keys and mnemonic words for the user, and stores the corresponding public chain addresses, private keys and mnemonic words of the user on the alliance chain. It should be noted that, an operation node is set in advance on the federation chain, and is specifically used for storing a public chain address, a private key and a mnemonic word allocated to a user.
By the method, the user identity information is confirmed by the alliance chain, and public chain addresses, private keys and mnemonics of all nodes of the public chain are managed, so that the evidence-based market is monitored conveniently, and stable operation of the evidence-based market is guaranteed.
As shown in fig. 2, an embodiment of the present application provides a securities-type general-purpose trading system, including: a transaction initiation module 201, a mapping module 202, a query module 203, a broadcast module 204, and a billing module 205;

when the result obtained by the query module 203 indicates that the certification transaction on the federation is successful, the broadcast module 204 is configured to broadcast the certification transaction on the federation chain by the node, and write the queried result into the block;
the accounting module 205 is used for accounting nodes in the federation chain to write the pass-through transaction to the block.
In the embodiment of the present application, if it is determined that the certified transaction on the federation chain is successful, the accounting module 205 is further configured to generate a transaction success identifier and write the transaction success identifier and the certified transaction into the same block. If it is determined that the certified transaction on the federation chain has failed, the accounting module 205 generates a transaction failure flag and writes the transaction failure flag into the block.
