Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The data processing method based on the blockchain system can be applied to the application environment shown in fig. 1. Where the side chains 102 interact with the main chain 104 through a cross-chain gateway 106. The side chains 102 include at least two side chains, such as a first side chain and a second side chain. The main chain 102 may obtain a cross-chain event of the first side chain and certification information of the cross-chain event, perform cross-chain verification on the cross-chain event based on the certification information, and when the cross-chain event verification passes, send cross-chain event information of the cross-chain event to the second side chain, and perform data processing through the second side chain.
In one embodiment, as shown in fig. 2, a data processing method based on a block chain system is provided, and the block chain system may include a main chain and at least two side chains, which is illustrated by applying the method to the main chain in fig. 1. In particular, the method may be applied to a server of a main chain, where the server may be a single server or a server cluster, and may include the following steps:
step S202, a chain crossing event of the first side chain and certification information of the chain crossing event are acquired.
The blockchain refers to a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. A Block chain (Block chain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data Block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next Block.
In this embodiment, the blockchains may include different categories of blockchains, such as public chains, alliance chains, and private chains.
In this embodiment, the blockchain may include a blockchain underlying platform, a platform product service layer, an application service layer, and the like.
Specifically, when the first side chain generates a cross-chain event, a self-increment ID corresponding to the cross-chain event may be generated and placed in a block of the first side chain, that is, a block of the Merkle Tree, and the verification information of the cross-chain event, that is, the Merkle Root (also referred to as a Root hash value of the Merkle Tree) may be placed in a block header of the block, and after completion, the cross-chain event and the block height may be pushed out through the event.
In this embodiment, the main chain may obtain the chain crossing event of the first side chain based on the block header synchronized with the first side chain, and obtain corresponding certification information, that is, Merkle Proof, based on the self-increment ID of the chain crossing event.
And step S204, performing cross-chain verification on the cross-chain event based on the certification information.
The verification means that the main chain in the block chain system performs validity verification on the chain crossing event of the side chain, specifically, the block head is verified.
In this embodiment, the validity Verification of the block header by the main chain is performed by means of full block synchronization or SPV (simple Payment Verification).
In this embodiment, the check content may be different according to different chain types, and may include, but is not limited to, a hash check, a timestamp check, a difficulty check, a verification node signature check, and the like. For example, a chain Of POW (Proof Of Work), for example, the contents Of the check specifically include whether the block header includes a hash value Of the previous block header, a check timestamp, and a check difficulty (that is, the hash Of the block header needs to be smaller than a certain threshold). For the chain of POS (Proof of rights of sale), the contents of the check include whether the block header contains the hash value of the previous block header, a check timestamp, and a signature of the check verification node is greater than a certain threshold (generally 2/3).
In this embodiment, the main chain may be checked differently based on the type of side chain to generate corresponding results.
In this embodiment, the verification result may include verification pass or verification failure. Specifically, taking POS as an example, when all verification contents, that is, the hash value of the block header, the verification timestamp, and the signature of the verification node, are greater than a certain threshold and are all verified, it is determined that the verification passes, and when at least one verification fails, it is determined that the verification fails.
And step S206, when the cross-chain event passes the verification, sending the cross-chain event information of the cross-chain event to a second side chain, and performing data processing through the second side chain.
In this embodiment, when the main chain performs validity verification and when it is determined that the verification passes, the corresponding cross-link event information is sent to the second vehicle, and the second side chain performs processing, for example, sending the transaction parameter or the transaction information to the second side chain, so that the second side chain performs processing.
In this embodiment, the second side chain may invoke a service contract for specific data processing based on the service contract logic.
The method comprises the steps of obtaining a cross-link event of a first side link and certification information of the cross-link event, then carrying out cross-link verification on the cross-link event based on the certification information, sending cross-link event information of the cross-link event to a second side link when the cross-link event verification passes, and carrying out data processing through the second side link. Therefore, when cross-chain event verification is carried out, verification can be carried out through the main chain in the block chain system, then cross-chain event processing is carried out, and compared with the traditional mode that verification is carried out through the gateway, verification is carried out through the main chain, verification safety can be guaranteed, and then cross-chain event processing safety can be improved.
In one embodiment, verifying cross-chain verification based on attestation information may include: based on the certification information, invoking a cross-chain management contract; determining verification information corresponding to the chain crossing event according to a chain crossing management contract, wherein the verification information is synchronous when the chain crossing event occurs to the first side chain; and verifying the verification information through the verification information.
In this embodiment, each side chain and the main chain may be deployed with a cross-chain management contract, and when performing cross-chain, the cross-chain may be implemented only by calling a uniform method of the cross-chain management contract, without paying attention to specific cross-chain logic.
Specifically, the first side-chain may obtain the Merkle Proof by calling a cross-chain management contract and then send to the backbone. After receiving the Merkle Proof, the main chain may invoke a cross-chain management contract, acquire verification information, i.e., Merkle Root, from the synchronized block header, and then verify the Merkle Root through the verification information and the certification information.
The specific verification process may be as described above, and may include verification of a hash value, a check timestamp, and the like, which is not limited in this application.
In one embodiment, the method may further include: receiving a registration request of a side chain to be registered, wherein the registration request carries initial block header information; performing registration verification on a side chain to be registered based on initial block header information, and generating a corresponding verification result; and when the verification result indicates that the registration verification passes, determining that the side chain to be registered is successfully registered.
The registration request refers to a request for requesting registration, and the registration request may include specific request content.
In this embodiment, when initializing, the side chain to be registered may initiate a registration request to the main chain, and submit the side chain configuration information of the side chain to be registered and the initial block header information, where the block header information may include verifier information.
In this embodiment, after acquiring the initial block header information, the main chain may perform registration verification based on the acquired initial block header information, for example, the main chain may perform signature verification and the like based on the initial block header information.
In this embodiment, the side chain to be registered may also obtain the initial block header of the main chain at the same time, and perform registration verification based on the initial block header information in the initial block header of the main chain.
In this embodiment, the main chain may generate a corresponding registration verification result when performing registration verification on the initial block header, and determine that the registration of the to-be-registered side chain is successful when the verification result indicates that the registration verification passes.
As will be understood by those skilled in the art, the sign of successful registration may be that the pending side chain is determined to be successfully registered when the verification of registration of both the main chain and the side chain is passed.
In the above embodiment, the side chains to be injected are registered to the main chain, so that all the side chains are managed through the main chain, and the cross chains among all the side chains can be crossed through the main chain, compared with the traditional method of directly crossing any two chains, the scheme can reduce the complexity of the block chain system and improve the stability of the block chain system.
In one embodiment, the method may further include: acquiring a logout request of a registered side chain; determining a transaction event corresponding to the registered side chain according to the logout request; at the end of the transaction event, the registered side chain is logged out.
In this embodiment, if the registered side chain needs to logout, a logout application needs to be submitted to the main chain, that is, a logout request is sent to the main chain. After receiving the logout request, the main chain can determine the transaction event corresponding to the registered side chain, and when the transaction event is ended, the main chain carries out logout processing on the registered side chain. For example, taking asset transfer as an example, a user transfers assets from chain A to chain B, at which time chain B is to be deregistered, the user may transfer assets back to chain A, the transaction event ends, and the main chain may then deregister the registered side chain.
In one embodiment, the main chain may also set a buffer time beyond which chain B logs off and the user's assets in chain B will fail.
In one embodiment, obtaining the cross-chain event of the first side chain and the certification information of the cross-chain event may include: monitoring the first side chain through a cross-chain gateway; when a chain crossing request of a first side chain is monitored, a chain crossing event synchronized by a chain crossing gateway is obtained, and certification information obtained by the chain crossing gateway from the first side chain based on the chain crossing event is obtained.
In this embodiment, with continued reference to fig. 1, the side chains and the main chain may be connected by a cross-chain gateway.
Specifically, the main chain may monitor each side chain through the cross-link gateway, and monitor whether there is a cross-link request. As will be understood by those skilled in the art, the monitoring of the main chain on the plurality of side chains is parallel, and the main chain can monitor each corresponding side chain based on the cross-chain gateway corresponding to each side chain and acquire the synchronous cross-chain event.
Specifically, when a chain crossing event occurs in the side chain, the synchronization block header information may refer to the main chain, so that the main chain may acquire the chain crossing event.
Further, the main chain can acquire the certification information from the side chain through the cross-chain gateway and perform subsequent processing.
In one embodiment, referring to fig. 3, the main chain may include a cross-chain management module, a block header synchronization module, a multi-chain management module, and the like. The cross-chain gateway can synchronize the block head of the side chain synchronization to the block head synchronization module of the main chain, so that the cross-chain management module can acquire the block head information from the block head synchronization module when a cross-chain event occurs. Similarly, the inter-chain gateway may submit the acquired certification information, such as the Merkle certification, to the inter-chain management module, so that the inter-chain management module performs subsequent verification processing.
In this embodiment, the multi-chain management module of the main chain may further manage a plurality of side chains based on the obtained side chain information, such as registration management, logout management, side chain state management, and the like.
The side chain state comprises states of side chain registration in, registration success, cancellation in and cancellation. Taking registration as an example, specifically, the side chain state management is registration first, and the registration is successfully performed when voting approval is received by other members and the threshold number of votes is reached.
In one embodiment, the cross-chain event may include a cross-chain transaction.
In this embodiment, when the cross-chain event passes the verification, sending cross-chain event information of the cross-chain event to the second side chain, and performing processing through the second side chain may include: calling a service contract of the cross-chain transaction; determining a second side chain corresponding to the cross-chain transaction based on the business contract; and when the cross-chain event passes the verification, sending the transaction information of the cross-chain transaction to the second side chain, and processing through the second side chain.
In this embodiment, referring to fig. 4, when a first side chain (i.e., chain a) initiates a cross-chain transaction, a cross-chain management contract may be invoked by invoking a cross-chain interface according to a business contract a of the specific transaction, and a cross-chain is performed.
In this embodiment, the cross-chain management contract of the chain a may prove that the obtained Merkle is sent to the cross-chain gateway, and is sent to the main chain, that is, the chain B, through the cross-chain gateway, after the main chain completes verification, the business contract B of the cross-chain transaction may be called to determine a transaction object, that is, the second side chain, corresponding to the cross-chain transaction. Further, the main chain may send transaction information for the cross-chain transaction to the second side chain for processing by the second side chain.
