Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a blockchain information verification method, device and storage medium. Background Technology

[0002] Blockchain is being used more and more widely in various scenarios such as business cooperation and government approval. Accessing resources on the blockchain remotely via the Internet will become increasingly common.

[0003] Figure 1 The diagram illustrates a scenario for copyright protection. In processes ① to ⑤: evidence of infringement is collected via the web terminal by requesting the infringing website's page, such as a webpage snapshot or screenshot, from the blockchain and storing it on the chain.

[0004] exist In the process, the judicial web terminal retrieves evidence of infringement from the infringement evidence storage blockchain via the Internet.

[0005] A crucial prerequisite for remotely accessing blockchain resources is addressing the blockchain resources, which involves assigning an address to the blockchain resources and then accessing them from the internet.

[0006] Under current technological conditions, the traditional Internet addressing scheme is often used. That is, the blockchain designates an oracle that is open to the Internet and assigns it a URI (Uniform Resource Identifier). Remote users access the oracle through the URI and then use the blockchain's resources.

[0007] The shortcoming of existing technology is that this access scheme makes remote access to blockchain resources vulnerable to centralization. For example, if DNS is tampered with, the blockchain resources will become unreliable and untrustworthy. Summary of the Invention

[0130] In the technical solution provided by the embodiments of the present invention, due to the introduction of a "verification blockchain", the endorsement signature provided by the blockchain can be used to query whether there are endorsement signatures from other application systems for the business blockchain, thereby determining whether the business blockchain is trustworthy. That is, by scanning the list of endorsement signatures of the business blockchain resources on the verification blockchain, the security and trustworthiness probability can be calculated.

[0131] Because the verification blockchain is decentralized, the data on the blockchain is also decentralized. When an application system uses a business blockchain resource, if it believes that the resource is authentic and trustworthy, it endorses and signs the resource and appends the record to the entry for that business blockchain resource on the verification blockchain. Therefore, the security and trustworthiness of various business blockchain resources can be maintained in a decentralized manner without human intervention, avoiding the vulnerabilities of manual management and centralization.

[0139] Figure 7 This is a schematic diagram of the application system structure in an embodiment of the present invention. Detailed Implementation

[0140] The inventor noticed the following during the invention process:

[0141] A blockchain designates an oracle that is open to the internet and assigns it a URI. Remote users access this oracle via the URI and then use the blockchain's resources. Thus, what was originally intended as accessing blockchain resources has now become accessing a specific oracle URI.

[0142] The drawback of this access scheme is that the access address is centrally managed.

[0143] Figure 2 This is a schematic diagram of the DNS system architecture. As shown in the figure, Internet URIs are managed centrally by secular society. For example, a URI:

[0144] http: / / oracle1.blockchain.aCloud.com.cn / chainid=xxx&channeld=xxx&smartcontract=xxx……

[0145] The domain name oracle1.blockchain.aCloud.com.cn is the foundation for blockchain. Domain names and DNS (Domain Name System) resolution services are organized and managed hierarchically, starting from the root domain. Each layer has a centralized management body, and then data converges to the layer above for centralized management.

[0146] If the internet's DNS system is tampered with, it will pose a risk to the use of blockchain.

[0147] In other words, in the early stages of blockchain applications, the "DNS addressing based on oracle URIs" method was the only universally usable access method, but it had centralized vulnerabilities. For example, if DNS was tampered with, blockchain resources would become unreliable and untrustworthy.

[0148] Based on this, the present invention provides a blockchain information verification scheme, and the specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0149] The solution introduces a "blockchain verification platform," which can verify the authenticity and availability of a blockchain resource through some means.

[0150] The platform is decentralized and is a blockchain (verified blockchain). Participating nodes include several systems that use resources from a certain blockchain.

[0151] Once a system has used blockchain resources, if it believes the usage process is authentic and trustworthy, it will endorse and sign the data, storing it on the verification blockchain.

[0152] Before using blockchain resources, a system can verify the authenticity and usability of the oracle URI on the verification platform. If other systems have already used the resource and deemed it authentic and trustworthy, then access can proceed. Otherwise, other measures can be taken, such as offline verification.

[0153] The platform can verify either oracles that access blockchain resources or the blockchain resources themselves.

[0154] First, the implementation environment will be described.

[0155] Figure 3 The diagram illustrates a blockchain information verification implementation environment. An environment capable of implementing blockchain information verification can include, as shown, an internet DNS server, several application systems, a business blockchain and its corresponding oracle, and a verification blockchain and its corresponding oracle. The application systems are existing equipment.

[0156] Figure 4 The diagram illustrates the implementation process of a blockchain information verification method on the application system side, and may include:

[0157] Step 401: The application system obtains the oracle address of the business blockchain;

[0158] Step 402: The application system queries the verification blockchain to see if there are endorsement signatures from other application systems for the business blockchain, and / or uses the resources of the business blockchain through the oracle address, wherein the verification blockchain stores endorsement signature information for each business blockchain.

[0159] Step 403: When the application system has endorsement and signature from other application systems and / or when it considers the usage process to be secure and trustworthy, it determines that the business blockchain information is trustworthy.

[0160] During implementation, if the use process is deemed safe and reliable, it may further include:

[0161] Step 404: Endorsement and signature of the business blockchain information on the verification blockchain.

[0162] Figure 5 The implementation process of the blockchain information verification method on the blockchain side is illustrated in the diagram, and may include:

[0163] Step 501: Verify the blockchain to receive queries from application systems. The query is to check whether there are endorsement signatures from other application systems for the business blockchain. The verification blockchain stores endorsement signature information for each business blockchain.

[0164] Step 502: Verify that the blockchain provides endorsement and signature information for application system query.

[0165] In practice, it may further include:

[0166] Step 503: When the application system deems the usage process safe and trustworthy, the application system provides an endorsement and signature for the business blockchain information on the verification blockchain.

[0167] The following is combined Figure 3 The verification process is explained.

[0168] 1. The application system queries the DNS server for the oracle URI of the business blockchain to obtain the IP address;

[0169] 2. Application system accesses and verifies the blockchain.

[0170] When querying the oracle URI and IP of a business blockchain on the verification blockchain, if certain conditions are met, such as other application systems having endorsed and signed the oracle URI of the business blockchain, then the oracle URI of this business blockchain is considered to be genuine and trustworthy.

[0171] 3. Application systems access and use resources from the business blockchain.

[0172] 4. After use, if the application system deems the use process safe and trustworthy, it can access and verify the blockchain to endorse and sign the blockchain resources for this business.

[0173] Steps 2 and 4 above may be performed only once, or both may be performed.

[0174] Implementing only steps 1-2-3 means that the application system merely verifies the security and trustworthiness of the business blockchain and uses the business blockchain resources, but refuses to endorse and sign its true availability.

[0175] Implementing only steps 1-3-4 means that the application system directly uses the business blockchain resources without verifying the business blockchain, and is willing to endorse and sign its true availability after use so that it can be used as a reference for other application systems in the future.

[0176] The implementation of the verification blockchain is explained below.

[0177] In implementation, the business blockchain information includes one or a combination of the following:

[0178] Information about business blockchains, information about business blockchain resources, and information about business blockchain oracles.

[0179] Implementation of ledger data.

[0180] The ledger for verifying a blockchain can support the following data structures:

[0181]

[0182]

[0183] During implementation, the above data structure supports recording the actual feasibility for the following objects:

[0184] 1. Business blockchain;

[0185] 2. Business blockchain resources;

[0186] 3. Business blockchain oracle.

[0187] The following explains the specific methods of implementing this using smart contracts.

[0188] Smart Contract 1: Query whether a certain business's blockchain resources are authentic and trustworthy.

[0189] During implementation, on the application system side, it queries whether there are endorsement signatures from other application systems for the blockchain related to the business, including:

[0190] Determine the blockchain information of the business to be queried;

[0191] Query the list of authentic and trustworthy endorsement signatures corresponding to the blockchain information of this business on the blockchain ledger, verify the endorsement signatures of each application system, and calculate the probability of true availability.

[0192] The probability of obtaining the true availability of blockchain information for this business.

[0193] Correspondingly, on the blockchain side:

[0194] During implementation, querying whether the blockchain for the stated business has endorsement signatures from other application systems includes:

[0195] The blockchain ledger provides a list of authentic and trustworthy endorsement signatures corresponding to business blockchain information, which is used to verify the endorsement signatures of each application system and calculate the probability of the true availability of the business blockchain.

[0196] Output the probability of the true availability of the blockchain information for this business.

[0197] In practice, the probability of true availability is calculated according to one or a combination of the following rules:

[0198] Are there a predetermined number of application systems that have already been endorsed and signed?

[0199] Whether a predetermined number of application systems that have reached a predetermined credit weight have already endorsed and signed the document;

[0200] Whether the endorsement and signature are within the set time period.

[0201] The specific explanation is as follows:

[0202] Input: Business blockchain resources; see "Business Blockchain Resources" above for data structure.

[0203] Logic: Query the list of authentic and trustworthy endorsement signatures corresponding to the "business blockchain resource" on the verification blockchain ledger, verify the endorsement signatures of each application system, and calculate the probability of true availability.

[0204] Example of a rule:

[0205] Rule 1: A sufficient number of application systems have endorsed and signed it.

[0206] Rule 2: A sufficient number of "authoritative" application systems have endorsed and signed the application. That is, the endorsement and signature of certain application systems carries higher weight.

[0207] Rule 3: The endorsement signature must be "new" enough and not expired.

[0208] Rule 4: A logical combination of Rules 1, 2, and 3.

[0209] Output: Probability of true availability.

[0210] Smart Contract 2: Endorses and signs to verify the authenticity and trustworthiness of blockchain resources for a certain business.

[0211] During implementation, on the application system side, the blockchain information for this business is endorsed and signed, including:

[0212] Determine the business blockchain information that requires endorsement and signature, as well as the endorsement and signature of this application system;

[0213] After verifying the validity of the endorsement signature, the verification blockchain appends the endorsement signature to the list of endorsement signatures for the blockchain information related to that business in the verification blockchain's ledger.

[0214] Correspondingly, on the blockchain side:

[0215] The application system provides endorsement and signature for the blockchain information of this business, including:

[0216] After verifying the validity of the endorsement signature of the blockchain verification application system, the endorsement signature is appended to the endorsement signature list corresponding to the blockchain information of that business.

[0217] The specific explanation is as follows:

[0218] enter:

[0219] A) Business blockchain resources, data structure as described above for "Business Blockchain Resources".

[0220] B) Endorsement signature of this application system. Data structure: see "Endorsement signature" above.

[0221] logic:

[0222] A) Verify whether the endorsement signature is valid.

[0223] B) Append the endorsement signature to the endorsement signature list of the business blockchain resource. Add a new entry for this business blockchain resource as needed. The data structure is the same as the "endorsement signature" above.

[0224] Output: None.

[0225] Smart Contract 3: Remove outdated endorsement signatures.

[0226] On the blockchain side, it is as follows:

[0227] In practice, it may further include:

[0228] Verifying the blockchain allows for the removal of endorsement signatures.

[0229] In practice, the blockchain is verified to be able to delete endorsement signatures, including:

[0230] Examine the timestamp of the endorsement signature on the ledger. If the timestamp is outside the preset valid time period, delete the endorsement signature. If the business blockchain information no longer has a corresponding endorsement signature, delete the entry for that business blockchain information.

[0231] The specific explanation is as follows:

[0232] Input: None, triggered periodically.

[0233] Logic: Scan all business blockchain resources on the ledger and scan their endorsement signature list:

[0234] A) Examine the timestamp of the endorsement signature. If the timestamp is too old relative to the current time, delete the endorsement signature.

[0235] B) If a business blockchain resource no longer has any endorsed signatures, then delete the entry for that business blockchain resource.

[0236] Output: None.

[0237] Based on the same inventive concept, this invention also provides a blockchain verification system, an application system, and a computer-readable storage medium. Since the principles by which these devices solve problems are similar to those of the blockchain information verification method, the implementation of these devices can refer to the implementation of the method, and repeated details will not be repeated.
