Detailed Description
The embodiment of the application provides a method and a device for creating a block chain, a data cross chain and a sales block chain and a personal block chain.
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a method for creating a blockchain according to an embodiment of the present disclosure.
And S101, performing real-name authentication by using the block chain account.
And (4) performing real-name authentication by using the block chain account, and performing subsequent steps only after the authentication is passed, and directly ending when the authentication is not passed. Currently, a mature blockchain is not available for providing real-name authentication services, a third-party service is often used for real-name authentication, and the quality of real-name authentication services provided by different countries and regions and different service providers is different. It is often necessary to design multiple solutions to deal with the different situations that may arise.
Optionally, a plurality of third-party real-name authentication services may be used, and the third-party real-name authentication services are used as data sources for the method for creating the blockchain.
Preferably, the blockchain information is built by self, the real-name authentication information of the blockchain account is collected, the collected real-name authentication information is examined, and then the real-name authentication information is further screened by using a plurality of third-party real-name authentication services.
Preferably, identity authentication and bank authentication are completed in the real-name authentication process, and optionally, face recognition can also be performed in the real-name authentication process. Thus, the effect of real-name authentication can be ensured to the maximum extent.
It should be noted that the real-name authentication maximally ensures that the blockchain account has a real identity in real life, but depending on a third-party service, sometimes the blockchain account after the real-name authentication cannot be the identity in real life.
And S102, generating creating information.
Generating creation information for creating the block chain after the real-name authentication passes, wherein the creation information comprises the block chain account and the result of the real-name authentication. Preferably, the creation information further includes a block chain number.
The result of the real-name authentication depends on the real-name authentication technique adopted in S101, and the obtained results are also different.
Preferably, the result of the real-name authentication at least includes a hash of the name of the blockchain account and a hash of all real-name authentication information. The two kinds of hash are convenient for tracing the real-name authentication information subsequently, and do not reveal the real information of the user.
S103, creating a block chain by using the creation information.
And loading the created-appearance information creating block chain by using a basic chain, wherein the basic chain is a pre-created chain, the basic chain identifies the created-appearance information, and the created-appearance information is written into a created-appearance block of the block chain.
Wherein a new block is created and consensus is initiated for the new block by a node participating in a consensus accounting of the blockchain using the blockchain account or an account that has been authorized by the blockchain account.
Preferably, a third party blockchain account that is permitted to participate in consensus billing is also required to perform consensus checking on the blocks to prevent the blocks that are generated badly by the blockchain account from not meeting basic requirements of traceability, non-tampering and the like of the blockchain.
Optionally, if the consensus mechanism of the blockchain is based on a raft consensus mechanism, a practical byzantine consensus mechanism, or other mechanisms, the consensus mechanism needs to be modified, and a blockout node is forced to be a node participating in the consensus accounting of the blockchain for the blockchain account or an account authorized by the blockchain account. And if the block outlet node is abnormal, stopping the block outlet of the block chain until the block outlet node returns to normal. In nodes participating in a consensus mechanism, the blockchain accounts and the number of accounts that have been authorized by the blockchain accounts are less than the minimum number for the consensus mechanism used to achieve consensus. The blockchain account and the account authorized by the blockchain account are already signed by the blockchain account, and a signature of a third party blockchain account permitted to participate in consensus billing is also required to be linked. Thus, the modified consensus mechanisms ensure that the blockchain account is responsible for the time and content of the block, and also ensure that the blockchain receives supervision and must meet the basic requirements of the blockchain to be able to uplink.
It should be noted that the blockchain account fully controls the data on the blockchain according to the wishes of the account, and also follows the basic requirements of the blockchain.
Preferably, the creation information further includes a block chain number, the basic chain identifies the block chain number in the creation information, and the block chain number in the creation information is used as the number of the block chain. Preferably, different users are identified by real-name authentication, and the blockchain numbers of different users are different, so that each user has a different blockchain number.
Fig. 2 is a flowchart of a method for data chaining according to an embodiment of the present application.
S201, receiving data cross-link transaction.
A data cross-chain transaction is received that includes transactions on other blockchains and their uplink credentials.
Preferably, the initiator of the data cross-chain transaction is not required to be an account on the blockchain that can pay a commission fee, and even more required to be the initiator of the transaction contained in the data cross-chain transaction.
Preferably, the signature of the data cross-chain transaction must be the signature of the initiator of the transaction.
Optionally, since the data cross-chain transaction is used to store transactions on other blockchains and uplink certificates thereof on the blockchains, and as the blockchains collect or backup transactions on other blockchains of the related accounts, the issue of who initiates the data cross-chain transaction is not important, and further, the value of the data cross-chain transaction is not affected when the signature of the data cross-chain transaction is empty.
S202, the transaction and the uplink certificate contained in the cross-chain transaction are analyzed and verified.
And analyzing the transactions and the uplink certificates thereof on other blockchains contained in the data cross-chain transaction, verifying whether the signatures and the uplink certificates thereof of the transactions on other blockchains contained in the data cross-chain transaction are correct, and rejecting the data cross-chain transaction if errors occur.
Optionally, the uplink certificate includes a block header of a block to which the transaction on the other blockchain belongs, and a mercker certificate of the transaction on the other blockchain at the block, where the transaction is certified at the block by the transaction on the other blockchain, the block header of the block to which the transaction on the other blockchain belongs, and the mercker certificate of the transaction on the other blockchain at the block. Further, the uplink certificate further includes a certificate of the block on the chain. When the other blockchains use a workload certification mechanism or other mechanisms, preferably, a third party blockchain or a service provides mathematical certification of the block headers on the other blockchains for the other blockchains; optionally, the uplink certificate provides a code for querying the block header in the other block chains, so as to query whether the block header is on the other block chains in real time. When the other blockchains use a consensus mechanism such as a practical byzantine consensus mechanism, the signature contained in the blockhead can prove that the blockhead is on the other blockchains.
If the other blockchains and the blockchains have different structures, additional code development is required to support analysis of the transactions of the other blockchains and uplink certificates thereof.
It should be noted that, when verifying the transactions on other blockchains included in the system, only the signature and the uplink certificate need to be verified to be accurate, and the service logic included in the data does not need to be verified.
S203, confirming whether the data cross-chain transaction can enter a transaction pool.
Whether the data cross-chain transaction can enter the transaction pool depends on three verifications.
First, it is verified that the initiator or receiver of the transaction on other blockchains included in the cross-chain data transaction is within the data cross-chain admission list of the blockchain, and if the initiator or receiver of the transaction on other blockchains included in the cross-chain data transaction is not within the data cross-chain admission list, the data cross-chain transaction is rejected. The data cross-link admission list, wherein any account is the initiator or the receiver of the transaction on other block links contained in the cross-link data transaction, the transaction pool of the block link node receives the data cross-link transaction, and the account is responsible for paying the commission charge when the block link is linked up in the data cross-link transaction; and the data cross-chain transaction enters a transaction pool of the blockchain node. In this way, the other blockchains can push the transactions and the uplink certificates to the corresponding blockchains, so that the data cross-chain transaction solves the difficulty of paying the uplink procedure fee, and the transactions and the uplink certificates thereof can be stored in the blockchains as long as the transactions are related to the accounts in the data cross-chain admission list.
It should be noted that the data cross-link admission list not only limits the range of the block chain to be linked, but also bears the cost of the block chain to be linked in the data cross-link transaction, so as to encourage other block chains to push their transaction and uplink certificates onto the block chain, and reduce the workload and difficulty of the block chain in collecting other block chains for accounts in the data cross-link admission list.
Optionally, when the initiator and the receiver of the transaction on other blockchains included in the cross-chain data transaction are both in the data cross-chain admission list of the blockchain, the initiator and the receiver pay the commission fee of the block chain linked up in the data cross-chain transaction on average.
Secondly, before the data cross-chain transaction enters the transaction pool of the blockchain node, it is also required to verify whether the transactions on other blockchains included in the data cross-chain transaction have entered the transaction pool or have linked the blockchain, and if the transactions have entered the transaction pool or have linked the blockchain, the data cross-chain transaction is rejected from entering the transaction pool of the blockchain node. This prevents transactions on the other blockchains from being repeatedly committed to the blockchain.
And finally, after the data cross-chain transaction is deleted from the transaction pool of the blockchain node, the hash values of the transactions on other blockchains included in the data cross-chain transaction are marked as an ignored state, before the data cross-chain transaction enters the transaction pool of the blockchain node, whether the hash values of the transactions on other blockchains included in the data cross-chain transaction are marked as the ignored state is verified, and if the hash values are marked as the ignored state, the data cross-chain transaction is rejected to enter the transaction pool of the blockchain node. Therefore, if the user of the blockchain can reject the transactions on the other blockchains which are not concerned, furthermore, some filtering rules can be set to directly reject the transactions which do not meet the rules, for example, the transactions which do not meet the rules are directly rejected, for example, the transactions which do not meet the rules are ignored, some transaction types are ignored, and the ignored amount is less than a certain value. Therefore, massive transactions of accounts in the data cross-chain admission list on other blockchains can enter a transaction pool of the blockchain node after effective screening, and unnecessary transactions are not required to be received completely or repeatedly.
S204, if the data cross-chain transaction can be added into the transaction pool, the cross-chain transaction enters the transaction pool.
And the data cross-chain transaction enters a transaction pool to wait for adding a new block.
Fig. 3 is a schematic diagram illustrating a method for deregistering a block chain according to an embodiment of the present disclosure.
S301, receiving death evidence.
A proof of death for an account on the blockchain used to create a new block is received.
Alternatively, if the death certificate is a digital certificate provided by the relevant government sector, and the blockchain accepts the digital certificate, the transaction is created directly and the upper chain is prepared to include the death certificate.
Optionally, if the death certificate material is obtained by taking a picture of a paper certificate provided by a relevant government department, a third-party service needs to be set up or used to verify the death certificate, and after the verification is passed, the block chain provides a corresponding digital certificate version of the death certificate, and receives the digital version of the death certificate provided by the third-party service.
S302, verifying death certificate
And verifying the death certificate, and if the death certificate is not the death certificate of the account used for creating the new block, directly reporting an error and canceling the logout process.
Alternatively, if the death certificate is a digital certificate provided by the relevant government department, it is necessary to confirm whether the digital certificate is valid using a digital service provided by the corresponding government department.
Alternatively, if the death certificate is a digital certificate provided by a third party service, it is necessary to confirm whether the digital certificate is valid using the third party service.
Preferably, the proof of death must contain the address of the account that created the new block.
Preferably, the blockchain notifies the existing client of the account creating the new block of the death certificate transaction for a plurality of times within a certain time, and if the account creating the new block refuses to accept the death certificate within the certain time, the verification fails, the logout process is interrupted, and the logout fails.
Preferably, the transaction containing the proof of death may be created from any account, as long as the signature of the transaction is the correct signature of the originator of the transaction.
S303, a new block is created, which only contains death certificates.
A new block is created that contains only the proof of death. Considering that the account creating the new block cannot be left to others in time when the account is dead, and the account cannot be used normally, the block chain provides that the block chain is valid when the new block only containing death certificate is agreed with the default that the new block does not have the signature of the account creating the new block.
S304, the new block is uplinked and the block chain is terminated.
And when the new block is uplink, the block chain is terminated, and the block chain does not create a new block any more.
Preferably, the blockchain closes the transaction and no more transactions are received.
Optionally, the block chain further provides a query service, which facilitates querying existing blocks and transactions on the chain.

In fact, any social member must interact with other social members, and cannot be a stand alone, non-communicative object, without exception to individuals. Similarly, any blockchain cannot be an island, and each blockchain creates its own data and depends on data provided by other blockchains. Therefore, the individual-oriented blockchain not only supports the user to operate and maintain the user as an individual territory, but also supports the transaction on other blockchains to be synchronized to the individual blockchain, so that an individual in the society can be completely depicted through one blockchain.
