Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
The block chain technique is described first.
Blockchains are generally divided into three types: public chain (Public Blockchain), Private chain (Private Blockchain) and alliance chain (Consortium Blockchain). Furthermore, there may be a combination of the above types, such as private chain + federation chain, federation chain + public chain, and so on.
Among them, the most decentralized is the public chain. Participants joining the public chain (also referred to as nodes in the blockchain) can read the data records on the chain, participate in transactions, compete for accounting rights for new blocks, and so on. Moreover, each node can freely join or leave the network and perform related operations.
Private chains are the opposite, with the network's write rights controlled by an organization or organization and the data read rights specified by the organization. Briefly, a private chain may be a weakly centralized system with strict restrictions on nodes and a small number of nodes. This type of blockchain is more suitable for use within a particular establishment.
A federation chain is a block chain between a public chain and a private chain, and "partial decentralization" can be achieved. Each node in a federation chain typically has a physical organization or organization corresponding to it; the nodes are authorized to join the network and form a benefit-related alliance, and block chain operation is maintained together.
Based on the basic characteristics of a blockchain, a blockchain is usually composed of several blocks. The time stamps corresponding to the creation time of the block are recorded in the blocks respectively, and all the blocks form a time-ordered data chain according to the time stamps recorded in the blocks strictly.
The data generated outside the chain can be constructed into a standard transaction (transaction) format supported by the blockchain, then the data is issued to the blockchain, the node devices in the blockchain perform consensus on the transaction, and after the consensus is achieved, the node devices serving as accounting nodes in the blockchain package the transaction into blocks, and the persistent evidence is stored in the blockchain.
The consensus algorithm supported in the blockchain may include:
the first kind of consensus algorithm, namely the consensus algorithm that the node device needs to contend for the accounting right of each round of accounting period; consensus algorithms such as Proof of Work (POW), Proof of equity (POS), Proof of commission rights (DPOS), etc.;
the second kind of consensus algorithm, namely the consensus algorithm which elects accounting nodes in advance for each accounting period (without competing for accounting right); for example, a consensus algorithm such as a Practical Byzantine Fault Tolerance (PBFT) is used.
In a blockchain network employing a first type of consensus algorithm, node devices competing for billing rights can execute a transaction upon receipt. One of the node devices competing for the accounting right may win in the process of competing for the accounting right in the current round, and become an accounting node. The accounting node may package the received transaction with other transactions to generate a candidate block and send the generated candidate block or a block header of the candidate block to other node devices for consensus.
In the block chain network adopting the second type of consensus algorithm, the node equipment with the accounting right is agreed before accounting in the current round. Thus, the node device, after receiving the transaction, may send the transaction to the accounting node if it is not the accounting node of its own round. For the accounting node of the current round, the transaction may be performed during or before packaging the transaction with other transactions to generate candidate blocks. After generating the candidate block, the accounting node may send the candidate block or a block header of the candidate block to other node devices for consensus.
As described above, regardless of which consensus algorithm is used by the blockchain, the accounting node of the current round may package the received transaction to generate a candidate block and send the generated candidate block or the block header of the candidate block to other node devices for consensus verification. If no problem is verified after the other node device receives the candidate block or the block header of the candidate block, the candidate block can be added to the end of the original block chain as the latest block, thereby completing the accounting process of the block chain. The transaction contained in the block may also be performed by other nodes in verifying the new block or block header sent by the accounting node.
The blockchain technology can make the stored data difficult to be tampered, and therefore can be used for meeting the data storage requirement.
At present, a data card storage business mode is to construct a data card storage system including two blockchain networks (referred to as a first blockchain network and a second blockchain network herein), where the first blockchain network is used to register a user identity, that is, a user may submit relevant information for proving his identity to the first blockchain network, and the first blockchain network stores the information, so that the first blockchain network registers the user identity. It should be noted that the first blockchain network may register a plurality of user identities. It should be noted that the user may be an individual or an organization.
The second blockchain network is to: and storing the data evidence storing transaction submitted by the user identity registered in the first blockchain network. If a user wants to submit data generated by the user to a second blockchain network for storing the certificate, a data certificate storing transaction needs to be constructed, wherein the data certificate storing transaction comprises the data to be stored (or the hash value of the data to be stored) on one hand and user identity information (used for proving the identity of the user submitting the data certificate storing transaction) on the other hand. Typically, to ensure that the identity of the user submitting the data credentialing transaction is authentic, the user identity needs to be registered in the first blockchain network in advance.
Each node of the second blockchain network generally performs consensus according to a certain rhythm (e.g., periodically or whenever a certain amount of transactions are accumulated), and determines a block to be written into the blockchain (also referred to as a to-be-sent block) corresponding to the consensus in the round, where the block includes a batch of data storage transactions. Each node of the second blockchain network writes a block into the blockchain (performs a block out operation on the block), meaning that each data credentialing transaction in the block is written into the blockchain.
However, sometimes the second blockchain network accepts data credentialing transactions submitted by untrusted user identities (not registered in the first blockchain network) and possibly packages such data credentialing transactions into blocks. Therefore, how to effectively prevent the second blockchain network from writing the data authentication transaction submitted by the untrusted user identity into the blockchain is a technical problem to be solved urgently.
For this reason, in one or more embodiments provided in this specification, in consideration of the data storage scenario, it is necessary to ensure that a data storage transaction stored in the second blockchain network is submitted by a user identity registered in the first blockchain network, and for this purpose, a block output control device independent from the first blockchain network and the second blockchain network is deployed in the data storage system, and the block output control device controls block output operations of each node in the second blockchain network. Specifically, for a block to be taken out in the second blockchain network, the block out control device needs to query one by one whether a user identity corresponding to each data certificate transaction in the block is registered in the first blockchain network, and in addition, each node of the second blockchain network takes out the data certificate transaction with a query result being no from the block in a mode of sending a control instruction to each node of the second blockchain network, and then the block out operation can be performed.
Fig. 1 is a flowchart of a block output method of a blockchain network provided in the present specification, including the following steps:
s100: and the block outgoing control equipment acquires the block to be subjected to block outgoing, which is determined by each node of the second block chain network based on a consensus mechanism.
S102: the block output control equipment inquires whether the user identity for submitting the data storage transaction is registered in the first block chain network or not aiming at each data storage transaction in the block.
S104: after S102, the out-of-block control apparatus transmits a control instruction to each node of the second blockchain network.
S106: and each node of the second block chain network takes out the data evidence transaction with the inquiry result of no from the block according to the control instruction.
S108: after S106, the second blockchain network performs a block out operation on the block.
In one or more embodiments of the present description, a block control device is deployed in a data storage and verification system, and the block control device is configured to control block output operations of nodes of a second blockchain network.
The block determined by each node of the second blockchain network based on the consensus mechanism is a block to be written into the blockchain, that is, a block to be written out. The block output control device may monitor operation of each node in the second block chain network, and when each node in the second block chain network completes one consensus, obtain a block corresponding to the consensus.
It should be noted here that, for each node of the second blockchain network, it needs to be configured to: and responding to a control instruction sent by the block output control equipment to perform block output operation. Specifically, each node of the second blockchain network performs no block output operation for each round of consensus if no control instruction for the round of consensus is received.
It should be further noted that the consensus rhythm of each node of the first blockchain network is often not synchronous with the consensus rhythm of each node of the second blockchain network, a user may have previously submitted identity-related information to the first blockchain network before submitting a data deposit transaction to the second blockchain network, and the second blockchain network has not completed registration of the user identity when the first blockchain network has not yet reached to chain (i.e., has not yet reached to complete registration) the identity-related information submitted by the user, so that the data deposit transaction submitted by the user is packed into a block by each node of the second blockchain network and is ready to be written into the blockchain.
In order to wait for the first blockchain network to complete more user identities registration as much as possible, the block output control device may perform step S102 after each node of the second blockchain network has completed the current round of consensus and before the block output operation is to be performed, so as to query more trusted user identities as much as possible.
In some embodiments, when it is monitored that each node of the second blockchain network determines the block to be released based on the consensus mechanism, the block release control device may query, for each data deposit transaction in the block, whether a user identity that submits the data deposit transaction is registered in the first blockchain network.
In some embodiments, the block leaving control device may start timing when it is monitored that each node of the second blockchain network determines a block to be removed based on the consensus mechanism, and after a specified time period elapses, query, for each data deposit transaction in the block, whether a user identity for submitting the data deposit transaction is registered in the first blockchain network.
The specified duration can be set according to actual needs.
In some embodiments, the out-of-block control device may deploy a trusted execution environment (e.g., TEE) that may include out-of-block control logic to implement the functionality of the out-of-block control device (i.e., steps S100-S104). In this way it is ensured that the control instructions issued by the out-of-block control device are generated by authentic control logic.
Further, the trusted execution environment may also include a private key. The sending, by the block output control device, the control instruction to each node of the second blockchain network may specifically include: and the block output control device uses the private key to sign the control instruction in a trusted execution environment, and then sends the control instruction to each node of the second block chain network. Correspondingly, each node of the second blockchain network can take out the data deposit transaction with the inquiry result of no from the block under the condition that the signature verification of the control instruction is passed.
The signature of the control instruction serves to provide a trusted endorsement of the trusted execution environment. Each node of the second blockchain network verifies the signature of the control instruction, meaning that the control instruction is issued by a trusted execution environment and is sufficiently trusted.
In addition, in some embodiments of the present description, each node of the second blockchain network writes the created block or a hash value of the created block to the created block, the hash value being assigned by the created block control logic or the created block. Since the block output operation of each node of the second blockchain network is controlled by the block output control device, the block output control logic can be written into the created block for evidence storage at the beginning of creation of the second blockchain network for trust requirement.
