Description

Technical Field

[0001] This invention relates to the field of digital measurement, reporting and verification (dMRV) technology, and in particular to a method, system, electronic device and non-transitory computer-readable storage medium for biochar carbon removal verification data processing based on physical-digital identity.

[0002] This invention further relates to a verification data processing technology that, based on the source-side verification evidence object prior to dMRV, acquires sealing path data, determines sealing path category status, verifies sealing path, and updates status identifiers for biochar physical output share at end-use stages such as packaging, storage, transportation, delivery, mixing, manufacturing, application, engineering application, deposition, or disposal. Background Technology

[0003] Carbon removal from biochar requires not only proof that the biomass feedstock forms stable carbon through carbonization or pyrolysis, but also proof that the resulting biochar ultimately enters a pathway capable of long-term sequestration. In existing technologies, production-side equipment data, weighing data, operating condition data, or testing data can be used to prove the fact of biochar production at the source. However, after biochar leaves the production facility, terminal processes such as packaging, storage, transportation, mixing, delivery, construction, land application, or disposal are often recorded by different entities, different systems, or different data formats, resulting in a lack of continuous link between the source-side verification evidence and the terminal sequestration facts.

[0004] The end uses of biochar are diverse. A single batch produced from the same source can be broken down into multiple packaging units, transported to different locations, or incorporated into soil amendments, building materials, engineering fillers, adsorbents, intermediate products, or sedimentary environments. The credibility, evidentiary fields, and reversal risks differ depending on the pathway. Relying solely on sales records, delivery slips, or shipping documents as evidence of end-use sequestration can easily lead to the erroneous inclusion of biochar that was not actually sequestered in carbon removal accounting.

[0005] In existing technologies, there is a lack of stable correlation between the evidence objects verified on the upstream source side and the terminal carrier objects. Packaging, transportation, finished product batches, terminal operations and engineering application data are scattered in different systems. There is a lack of a unified classification framework for paths such as mixed products, cascaded uses, long-life materials and passive deposition. Terminal path verification often only focuses on the delivery results and cannot combine the trusted state data of the upstream source side to make consistency judgments.

[0006] Existing technologies struggle to promptly identify non-sealed paths, path association anomalies, and reversal risks, and also find it difficult to trigger locking, exclusion, or write rejection processes in a timely manner. Therefore, at the end-use stage, it is difficult to prove that the digital data share identifier maintains physical-digital identity with at least a portion of the physical biochar production share.

[0007] Therefore, there is an urgent need for a technical solution that can continuously bind data share identifiers to sealed carrier object identifiers based on the evidence objects verified on the source side, and determine the path category, perform differentiated path verification, and update the status identifier based on the sealed path data, so as to reduce the risks of false sealing, path breakage, duplicate accounting, and reversal. Summary of the Invention

[0008] The present invention aims to provide a biochar carbon removal verification data processing method, system, electronic device and storage medium based on physical-digital identity, so as to at least solve the problems in the prior art that the source-side verification evidence object is difficult to continuously bind to the actual sealing path at the end-use stage, the sealing path category is difficult to uniformly determine, different end-use lacks differentiated verification, and non-sealing path or reversal risk is difficult to identify in a timely manner.

[0034] Secondly, the present invention can identify the status of direct land sealing, mixed product land application, cascade use tracking, long-life material sealing, passive deposition sealing, and non-sealing path identification, and is adapted to multiple terminal sealing paths, rather than simply equating sales, warehousing, or delivery with sealing completion.

[0057] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the following embodiments are used to explain the present invention, and not to limit the scope of protection of the present invention. For those skilled in the art, various substitutions, combinations or modifications can be made to the following embodiments without departing from the concept of the present invention.

[0058] In this invention, "preceding source-side verification evidence object" can refer to a data object generated by the source-side verification evidence generation system based on production equipment operation data, weighing data, production time window, operating condition data, quality status data, or other source-side evidence data, used to characterize that at least a portion of the physical biochar production share has been formed or is in a credible state.

[0059] In some implementations, the preceding source-side verified evidence object can be a complete evidence data object, or it can be an object identifier, hash pointer, evidence package index, database record, electronic signature record, trusted timestamp record, or a combination thereof pointing to the complete evidence data object. The data processing device can directly receive the preceding source-side verified evidence object, or it can indirectly reference or verify the preceding source-side verified evidence object through source-side trusted state data. This invention does not require the data processing device to regenerate the preceding source-side verified evidence object, nor does it limit the specific generation algorithm of the preceding source-side verified evidence object.

[0060] In some implementations, source-side trusted state data is used to characterize the trusted association status between a data share identifier and a preceding source-side verified evidence object. The source-side trusted state data may include at least one of the following: the identifier, hash value, signature value, trusted timestamp, production time window, batch status data, operating condition status data, quality status data, or evidence chain identifier of the preceding source-side verified evidence object. The data processing device can determine, based on the source-side trusted state data, whether the corresponding data share identifier can be trustedally associated with at least a portion of the physical biochar production share represented by the preceding source-side verified evidence object.

[0061] In this invention, a "data share identifier" is used to identify or associate in a digital system at least a portion of the physical biochar production share represented by a prior source-side verified evidence object. The data share identifier may correspond to a complete production batch, or it may correspond to a portion of the production batch, such as a mass share, volume fraction, packaging share, time window share, finished product batch share, or calculable share.

[0062] In this invention, a "storage carrier object identifier" is used to identify the physical or business object that carries, transfers, mixes, uses, constructs, deposits, or disposes of at least a portion of the physical biochar production. The storage carrier object identifier may include at least one of a packaging unit identifier, a transport unit identifier, a finished product batch identifier, an end-operation object identifier, or an engineering application object identifier.

[0063] In this invention, "storage path data" can refer to data associated with the identifier of the storage carrier object, used to characterize the final destination, use, operation, mixing, construction, deposition, or disposal status of the physical biochar production share. The storage path data can originate from warehousing and logistics systems, manufacturing execution systems, terminal operation systems, engineering application management systems, carbon asset platforms, auditing systems, manual data entry terminals, or edge data acquisition devices.

[0064] In this invention, the "sealage path category status" is used to characterize the path type or risk type of the corresponding physical biochar production share at the end-use stage. The sealage path category status is not a general commodity use classification, but rather a data processing status used to control the sealage path verification type, status identifier update rules, supplementary certification rules, and write rules.

[0065] In this invention, "status identifier update" can refer to updating, locking, freezing, excluding, or refusing to write to the verification status, sealed status, supplementary certification status, risk status, exclusion status, or write status corresponding to the data share identifier. Status identifier updates can be written to status records, audit traceability data, verification platforms, carbon asset platforms, or the full lifecycle dMRV module.

[0066] Example 1: Overall Method Example like Figure 1 and Figure 2 As shown, in some embodiments, the data processing device 120 performs a biochar carbon removal verification data processing method based on physical-digital identity. The data processing device 120 may be a server, an edge computing device, an industrial control computer, a cloud platform node, a blockchain gateway, a warehouse management system node, a logistics management system node, a manufacturing execution system node, an engineering management system node, a verification platform node, or a combination thereof.

[0067] In S1, the data processing device 120 acquires the data share identifier, source-side trusted status data, and sealed bearer object identifier, and establishes or updates the association between the data share identifier and the sealed bearer object identifier. The source-side trusted status data is used to characterize the trusted association status between the data share identifier and the preceding source-side verified evidence object.

[0068] In S2, the data processing device 120 acquires sealing path data associated with the identifier of the sealed carrier object. The sealing path data may include at least one of the following: outbound data, inventory data, transportation data, delivery data, product manufacturing data, mixed composition data, end-use data, operation location data, engineering application data, cascade use data, deposition environment data, or disposal destination data.

[0069] In S3, the data processing device 120 determines the sequestration path category status of at least a portion of the physical biochar production share corresponding to or associated with the data share identifier based on the sequestration path data. The sequestration path category status may include direct land sequestration status, mixed product land application status, cascade use tracking status, long-life material sequestration status, passive deposition sequestration status, or non-sequestration path identification status.

[0070] In S4, the data processing device 120 performs a sealing path verification corresponding to the sealing path category status based on the sealing path category status, sealing path data, and source-side trusted status data, on at least a portion of the physical biochar production share represented by the preceding source-side verification evidence object.

[0071] In S5, the data processing device 120 performs a status update corresponding to the data share identifier based on the result of the sealing path verification, so that the data share identifier is locked or changed to at least one of the following: sealing path confirmed, mixed product formed, cascade use continues to be tracked, long-life material sealing confirmed, passive deposition sealing confirmed, pending supplementary certification, reversal risk lock, exclusion or rejection of writing.

[0072] The data processing device 120 can output the status identifier update result to the verification platform or audit system 150. The verification platform or audit system 150 can determine, based on the status identifier update result, whether the corresponding data share identifier can be included in the carbon removal accounting, whether supplementary certification is required, whether it should be excluded, or whether it should be rejected and written into the subsequent verification results.

[0073] Example 2: Binding Data Share Identifier to Encapsulated Bearer Object like Figure 3 As shown, in some embodiments, the data share identifier 320 is used to identify at least a portion of the physical biochar production share 330 represented by the preceding source-side verification evidence object 310. A data share identifier may correspond to a complete output batch, or it may correspond to a portion of the output batch, a portion of the packaging unit, a portion of the transportation unit, a portion of the finished product batch, or a portion of the end-operation object.

[0074] One data share identifier can correspond to one packaging unit identifier; one data share identifier can correspond to multiple packaging unit identifiers; multiple data share identifiers can correspond to one transportation unit identifier; multiple data share identifiers can be mixed into one finished product batch identifier; one finished product batch identifier can further correspond to multiple terminal operation object identifiers; one data share identifier can correspond to one engineering application object identifier.

[0075] The association table or index record 350 is used to record the one-to-one, one-to-many, many-to-one, or multi-level association relationships between data share identifiers and packaging unit identifiers 341, transportation unit identifiers 342, finished product batch identifiers 343, terminal operation object identifiers 344, or engineering application object identifiers 345.

[0076] The aforementioned relationships can be implemented using index tables, database records, hash pointers, batch mapping tables, QR codes, RFID tags, electronic seals, electronic waybills, smart contract records, or combinations thereof. This invention is not limited to specific data storage formats, tag formats, encoding formats, or database structures.

[0077] The data processing equipment 120 can establish or update the association between the data share identifier and the sealed carrier object identifier when events such as packaging, warehousing, outbound, loading, transportation handover, delivery and receipt, feeding and mixing, terminal application, engineering construction or sediment disposal occur.

[0078] Example 3: Source-side trusted state data acquisition example The source-side trusted status data may include at least one of the following: prior source-side verification evidence identifier, prior status hash, device signature, trusted timestamp, output time window, batch status data, operating status data, quality status data, or evidence chain identifier.

[0079] Source-side trusted state data can be generated, forwarded, or signed by programmable logic controllers (PLCs), distributed control systems (DCSs), industrial control computers (IPCs), edge gateways, weighing equipment, packaging equipment, positioning equipment, sensing equipment, or source-side verifiable evidence generation systems.

[0080] In continuous carbonization production scenarios, source-side trusted status data can also generate hash values, signature values, or trusted status identifiers based on effective processing volume fluctuation characteristics, feed rate, discharge rate, reactor temperature, moisture content, ash content, bulk density, char yield, or equipment operating status.

[0081] The data processing device 120 does not need to re-execute the complete generation algorithm of the preceding source-side verified evidence object. Instead, it references or receives source-side trusted state data and confirms the trusted association state between the data share identifier and the preceding source-side verified evidence object based on the source-side trusted state data.

[0082] The source-side trusted state data can carry digital signatures, trusted timestamps, preceding state hashes, or evidence chain identifiers. The data processing device 120 can verify whether the data has been tampered with, whether it belongs to a specified production time window, whether it is consistent with the corresponding batch state, and whether it can be used as a preceding trusted basis for sealing path verification based on the above fields.

[0083] Example 4: Example of Obtaining Encapsulated Path Data The data processing device 120 acquires sealing path data associated with the identifier of the sealed object. The sealing path data may include at least one of the following: outbound data, inventory data, transportation data, delivery data, product manufacturing data, mixed composition data, end-use data, operation location data, engineering application data, cascade use data, deposition environment data, or disposal destination data.

[0084] Outbound data may include outbound order number, outbound time, warehouse location, outbound quality, packaging status, or the responsible party for outbound shipment. Inventory data may include inventory ledger, inventory location, inventory change records, inventory count results, or inventory anomaly records. Transportation data may include vehicle identification, waybill number, route, handover records, transportation time, transportation trajectory, or the responsible party for transportation.

[0085] Delivery data may include the recipient, delivery time, delivery location, customer confirmation, receipt, or delivery exception record. Product manufacturing data may include manufacturing milestones, material input records, production line identification, finished product batches, or manufacturing time windows. Mixing composition data may include blending ratios, formula ratios, ratio baselines, mixing time, or mixing equipment identification.

[0086] End-user data may include application records, construction records, personnel, equipment, or completion status. Location data may include plot number, latitude and longitude, geofence, construction coordinates, or work area identifier. Engineering application data may include project number, construction location, material curing status, construction completion status, or project acceptance status.

[0087] Cascaded use data may include primary use, intermediate products, subsequent destinations, transfer records, or post-treatment status. Sedimentary environment data may include sedimentary location, cover condition, environmental type, landfill layer, or sedimentary stability status. Disposal destination data may include fuel conversion, incineration, water release, abandonment, reactivation, short-lived consumption, or other disposal status.

[0088] Data processing device 120 can extract or generate path evidence fields from sealed path data or source-side trusted status data. Path evidence fields may include at least one of the following: quality field, composition ratio field, delivery object field, time field, spatial location field, finished product batch field, terminal operation field, cascade destination field, engineering application field, deposition environment field, preceding verification field, or reversal risk field.

[0089] Example 5: Example of General Encapsulation Path Verification Rules The archived path verification can be performed based on the path evidence field, source-side trusted status data, archived path data, archived carrier object identifier, and their associated relationships. Different verifications can be performed individually or in combination according to the archived path category status.

[0090] Pre-verification consistency checks can be used to determine whether the source-side trusted state data and the sealed path data are consistent in at least one of the following: trusted timestamp, pre-verification hash, device signature, batch state data, production time window, or evidence chain identifier. If the pre-verification hash, device signature, or trusted timestamp cannot be verified, the data processing device can generate a data inconsistency result, a result requiring supplementary verification, or a write rejection result.

[0091] Quality conservation verification can be used to determine whether the quality of outbound shipments, inventory changes, transportation handover, delivery, material input, finished product attribution, application, deposition, or combinations thereof meets preset consistency conditions. These preset consistency conditions may include quality difference thresholds, weighing equipment calibration status, packaging damage status, allowable loss range, manual verification results, or combinations thereof.

[0092] Composition ratio verification can be used to determine whether the biochar blending ratio, formulation ratio, ratio benchmark, feeding record, finished product batch quality, or combinations thereof meet a preset ratio relationship. The ratio benchmark may include a mass benchmark, dry basis mass benchmark, wet weight benchmark, volume benchmark, batch benchmark, or other verifiable ratio benchmark.

[0093] Delivery object verification can be used to determine whether the delivery object identifier, signed object, user confirmation data, delivery location, delivery time, or delivery voucher matches the sealed carrier object identifier or the preset terminal purpose path. Spatial location verification can be used to determine whether the operation location, construction location, deposition location, geofence, latitude and longitude, construction coordinates, transportation trajectory, or timestamped image data matches the preset sealed area.

[0094] Finished product batch attribution verification can be used to determine whether there is a consistent batch attribution relationship among the fields of material input batch identifier, product manufacturing node identifier, finished product batch identifier, finished product outbound status, or finished product usage. Terminal operation verification can be used to determine whether the terminal operation object identifier, operation time, operation equipment, operation personnel, operation completion status, or user confirmation data meet the preset terminal operation conditions.

[0095] Cascaded destination verification can be used to determine whether primary use data, intermediate product data, subsequent destination data, disposal destination data, land entry status, incineration risk status, or reactivation risk status can form a traceable subsequent destination chain. Engineering application attribution verification can be used to determine whether the building material manufacturing node identifier, finished material batch, engineering application object identifier, construction location data, engineering project attribution data, or material solidification status meet preset attribution conditions.

[0096] Deposition environment verification can be used to determine whether sedimentation location data, mixing state, sedimentation environment data, cover state, environment type, or reversible storage state meet preset sedimentation and storage conditions. Reversal risk verification can be used to identify risk states such as combustion, incineration, reactivation, migration, excavation, short-lived release, water body release, unverifiable destination, or other risks that may cause carbon removal results to be either not written or should be locked.

[0097] Example 6: Determining the Status of Sealed Path Category like Figure 4 As shown, the data processing device 120 determines the storage path category status of at least a portion of the physical biochar production share corresponding to or associated with the data share identifier based on the purpose field, delivery object, finished product batch, operation type, project affiliation, deposition environment, disposal destination, risk field or combination thereof in the storage path data 410.

[0098] The sequestration path category status includes at least one of the following: direct land sequestration status 421, mixed product land application status 422, cascade use tracking status 423, long-life material sequestration status 424, passive deposition sequestration status 425, or non-sequestration path identification status 426. Data processing device 120 can determine the sequestration path category status based on rule tables, path mapping tables, classification models, manual verification results, external audit results, or a combination thereof.

[0099] Direct land sequestration status 421 can refer to biochar being directly applied to farmland, forest land, grassland, mine restoration sites, degraded land, soil improvement plots, or other land sequestration objects. Data processing equipment 120 can determine the direct land sequestration status based on terminal operation object identification, operation location data, operation time data, application area data, user confirmation data, geofence data, or timestamped image data.

[0100] The land application status of the mixed product 422 can refer to the process where biochar is first mixed with soil conditioners, fertilizers, compost, substrates, compound products, or other mixed products before entering the land application path. The data processing equipment 120 can determine the land application status of the mixed product based on product manufacturing node identifier, feeding batch identifier, finished product batch identifier, biochar mixing ratio, ratio benchmark, product use field, finished product outbound status, or user delivery status.

[0101] Cascade Use Tracking Status 423 can refer to biochar first entering filter media, adsorbent materials, bedding, intermediate products, or other primary uses, and its subsequent destination still needs to be tracked. Data processing equipment 120 can determine the cascade use tracking status based on primary use data, intermediate product data, subsequent destination data, disposal destination data, land entry status, incineration risk status, or reactivation risk status.

[0102] The long-life material storage status 424 can refer to the presence of biochar in concrete, bricks, slabs, asphalt, composite materials, engineering fillers, building materials, or other long-life materials. Data processing equipment 120 can determine the long-life material storage status based on building material manufacturing node identifiers, formula ratios, finished material batches, engineering application object identifiers, construction location data, engineering project attribution data, or material curing status.

[0103] Passive sedimentation and sequestration status 425 can refer to biochar entering sedimentation, cover, landfill, mine backfilling, stockpiling, ecological restoration cover, or other sedimentary environments. Data processing equipment 120 can determine the passive sedimentation and sequestration status based on sedimentation location data, mixing state, sedimentation environment data, or reversible storage status.

[0104] Non-sequestration path identification status 426 can refer to biochar being used for fuel production, short-lived consumer products, water body release, abnormal disposal, or other uses that do not meet sequestration requirements. Data processing equipment 120 can determine the non-sequestration path identification status based on the fuel production status, short-lived consumer product status, water body release status, abnormal path association status, or abnormal disposal destination status.

[0105] The same data share identifier can correspond to different sequestration path category statuses at different times. For example, when biochar enters the blended product stage but final application evidence has not yet been obtained, it can be initially identified as a blended product land application status; once land application data is subsequently obtained, land sequestration-related verifications can be performed and the status identifier updated. The above dynamic update does not change the association between the data share identifier and at least a portion of the physical biochar production share.

[0106] Example 7: Direct Land Sealing Verification Example When the sealing path category status is or includes direct land sealing status, the sealing path verification includes direct land sealing verification. Direct land sealing verification may include mass conservation verification and spatial location verification, and may be performed based on at least one of the following: terminal operation object identifier, operation location data, operation time data, application area data, weight reduction curve data, user confirmation data, geofence data, or timestamped image data.

[0107] For example, a physical biochar production share corresponding to or associated with a certain data share identifier is packaged and transported to a farm plot, and then applied to designated land by application equipment. Data processing equipment 120 acquires transportation data, delivery data, terminal operation object identifier, operation location data, operation time data, application area data, weight loss curve data, user confirmation data, geofence data, and timestamped image data.

[0108] In the quality conservation verification, the data processing device 120 can determine whether the corresponding quality relationship meets the preset consistency conditions based on the outbound quality, transportation handover quality, delivery quality, pre-application quality, post-application remaining quality, weight reduction curve of the application equipment, or a combination thereof. The preset consistency conditions may include at least one of the following: quality difference threshold, error tolerance range, weighing equipment calibration status, packaging damage status, or manual verification results.

[0109] In spatial location verification, the data processing device 120 can determine whether the terminal operation occurred within a preset land sealing area based on work location data, geofence data, plot number, latitude and longitude, construction coordinates, timestamped image data, or positioning device signature. Spatial location verification can be further combined with transportation trajectory, delivery location, work equipment location, or user confirmation data.

[0110] Direct land sealing verification can also include operation time verification and terminal operation object verification. Operation time verification can be used to determine whether the application time falls within the time window that matches the outbound, transportation, delivery, or operation plan. Terminal operation object verification can be used to determine whether the terminal operation object identifier matches the sealing load object identifier, delivery object identifier, or land sealing object.

[0111] When the quality conservation check and spatial location check meet the preset pass conditions, the data processing device 120 can update the corresponding data share identifier to "sealed path verified". When there are abnormal quality differences, abnormal locations, missing evidence, or inconsistent work objects, the data processing device 120 can update the corresponding data share identifier to "pending supplementary verification". When the data clearly shows that no land application has been carried out, the land has entered a non-sealed use, or there is an irreversible path break, the data processing device 120 can update the corresponding data share identifier to "excluded" or "rejected from writing".

[0112] Example 8: Verification of Land Application of Mixed Products When the sealing path category status is or includes the mixed product land application status, the sealing path verification includes mixed product land application verification. Mixed product land application verification may include quality conservation verification, composition ratio verification, delivery object verification, and finished product batch attribution verification, and may be performed based on at least one of the following: product manufacturing node identifier, feeding batch identifier, finished product batch identifier, biochar blending ratio, ratio benchmark, delivery object identifier, product usage field, finished product outbound status, or user delivery status.

[0113] For example, biochar enters the soil conditioner production line and is mixed with compost, minerals, organic fertilizer, or other components to form a finished product batch. The Manufacturing Execution System sends the product manufacturing node identifier, feeding batch identifier, finished product batch identifier, biochar blending ratio, ratio benchmark, finished product outbound status, delivery object identifier, and product usage field to the data processing equipment 120.

[0114] In the quality conservation verification, the data processing device 120 can determine whether the quality of biochar entering the mixed product matches the physical biochar output share corresponding to or associated with the data share identifier based on the feed quality, the inventory quality before mixing, the finished product quality after mixing, the biochar attribution quality, the finished product outgoing quality, or a combination thereof.

[0115] In composition ratio verification, the data processing device 120 can determine whether the biochar proportion that can be attributed to the data share identifier in the corresponding finished product batch meets the preset ratio relationship based on the biochar blending ratio, formula ratio, ratio benchmark, feeding record, production line identification, mixing time, finished product batch quality, or a combination thereof. The ratio benchmark may include a quality benchmark, dry basis quality benchmark, wet weight benchmark, volume benchmark, batch benchmark, or other verifiable ratio benchmark.

[0116] In the finished product batch attribution verification, the data processing device 120 can determine whether there is a consistent batch attribution relationship among the material input batch identifier, finished product batch identifier, product manufacturing node identifier, and finished product outbound status. In the delivery object verification, the data processing device 120 can determine whether the delivery object, user delivery status, or product usage field corresponding to the finished product batch meets the land application path requirements.

[0117] When a finished product batch has been formed but final land application evidence has not yet been obtained, the data processing device 120 can update the corresponding data share identifier to "Mixed product formed." The "Mixed product formed" status does not necessarily indicate that final sealing is complete, but rather that biochar has entered a traceable finished product batch. Upon obtaining subsequent delivery records, land application records, operation location data, or user confirmation data for the finished product batch, the data processing device 120 can further update the corresponding data share identifier to "Sealing path confirmed."

[0118] When the formula ratio is missing, the batches of raw materials are inconsistent, the batch of finished product is unclear, or the delivery object does not meet the preset conditions, the data processing device 120 can update the corresponding data share identifier to "pending supplementary certificate". When the product use field shows non-land use, short-life consumption use, fuel use, or other uses that do not meet the sealing requirements, the data processing device 120 can update the corresponding data share identifier to "exclude" or "reject writing".

[0119] Example 9: Cascaded Application Tracking and Verification Example When the sealing path category status is or includes cascaded use tracking status, the sealing path verification includes cascaded use tracking verification. Cascaded use tracking verification may include prior verification consistency verification and terminal operation verification, and may be performed based on at least one of the following: primary use data, intermediate product data, subsequent destination data, disposal destination data, land entry status, incineration risk status, or reactivation risk status.

[0120] For example, biochar may first be used as filter media, adsorbent materials, livestock bedding, matrix pretreatment materials, or other intermediate uses, and may subsequently enter land, engineering materials, sedimentary environments, or non-sequestration disposal pathways. Data processing equipment 120 acquires data on the primary use, intermediate products, subsequent destinations, disposal destinations, land entry status, and incineration or reactivation risk status.

[0121] In the preceding verification consistency verification, the data processing device 120 can verify the consistency between the source-side trusted state data and the cascaded use data in at least one of trusted timestamps, preceding state hashes, device signatures, evidence chain identifiers, batch state data, or production time windows, to confirm that the share of physical biochar entering the first use or intermediate use still corresponds to at least a portion of the physical biochar production share represented by the preceding source-side verification evidence object.

[0122] During terminal operation verification, the data processing device 120 can determine whether the primary or intermediate application has a traceable operation object, usage scenario, processing node, transfer record, or subsequent destination. For cascaded applications that have not yet closed the loop, the data processing device 120 can record the continued tracking status and set subsequent supplementary certification conditions, tracking cycles, or risk triggering conditions.

[0123] Cascaded use tracking verification can also include cascaded destination verification and reversal risk assessment. Cascaded destination verification can be used to determine whether intermediate products have entered land sequestration pathways, long-lived material sequestration pathways, passive sedimentation sequestration pathways, or other qualified sequestration pathways. Reversal risk assessment can be used to identify risks such as incineration, fuel conversion, reactivation, migration, short-lived release, or unverifiable destination.

[0124] When the subsequent destination is not yet closed but a traceable chain of evidence still exists, the data processing device 120 can update the corresponding data share identifier to indicate cascaded use for continued tracking. When the subsequent destination enters a qualified land storage, long-life material storage, or passive sedimentation storage path and passes the corresponding verification, the data processing device 120 can update the corresponding data share identifier to indicate that the storage path has been confirmed, long-life material storage has been confirmed, or passive sedimentation storage has been confirmed. When the subsequent destination enters a fuel conversion, incineration, or other non-storage path, the data processing device 120 can update the corresponding data share identifier to indicate reversal risk locking, exclusion, or rejection of writing.

[0125] Example 10: Long-life material storage and verification example When the storage path category status is or includes long-life material storage status, the storage path verification includes long-life material storage verification. Long-life material storage verification may include mass conservation verification and engineering application attribution verification, and may be performed based on at least one of the following: building material manufacturing node identifier, formula ratio, finished material batch, engineering application object identifier, construction location data, engineering project attribution data, or material curing status.

[0126] For example, biochar can be used as a filler, admixture, functional component, or additive in building materials, engineering materials, or other long-life materials. The manufacturing execution system sends building material manufacturing node identifiers, formula ratios, finished material batches, and material curing status to the data processing equipment 120; the engineering application management system sends engineering application object identifiers, construction location data, and engineering project affiliation data to the data processing equipment 120.

[0127] In the quality conservation verification, the data processing device 120 can determine whether the biochar share that can be attributed to the data share identifier matches at least a portion of the physical biochar output share represented by the preceding source-side verification evidence object, based on the biochar feed quality, formula ratio, finished material batch quality, material loss data, cured material quality, or a combination thereof entering the building material manufacturing node.

[0128] In the engineering application attribution verification, the data processing device 120 can determine whether the finished material containing biochar has entered the preset engineering application object based on the engineering application object identifier, engineering project attribution data, construction location data, material batch, construction completion status, installation status, or material curing status. Engineering application objects may include buildings, roads, foundations, slope protection, mine restoration projects, ecological restoration projects, composite material products, or other long-life application objects.

[0129] Long-life material storage verification can also include material curing status verification and construction location verification. Material curing status verification can be used to determine whether the material has been cured, installed, shaped, or is in a state that is not easily reversed. Construction location verification can be used to determine whether the application location of the project is consistent with the project's ownership data or construction records.

[0130] When the formula ratio, finished material batch, and engineering application object identifier of the building material manufacturing node meet the preset attribution conditions, and the material curing status shows that it has been cured, installed, or entered a long-term use state, the data processing device 120 can update the corresponding data share identifier to "long-life material storage confirmed." When the material has been formed but no construction or engineering application evidence has been obtained, the data processing device 120 can update the corresponding data share identifier to "pending supplementary certification." When the material has not entered the project, the project is unclear, the material has been removed, or there is a risk of release, the data processing device 120 can update the corresponding data share identifier to "reversal risk lock," "exclusion," or "rejection of writing."

[0131] Example 11: Passive Deposition and Sequestration Verification Example When the storage path category is or includes passive deposition storage, storage path verification includes passive deposition storage verification. Passive deposition storage verification may include spatial location verification and depositional environment verification, and may be performed based on at least one of depositional location data, mixing state, depositional environment data, or reversible storage state.

[0132] For example, biochar can be deposited in sedimentation, cover, landfill, mine backfill, tailings cover, ecological restoration cover layers, or other passive storage environments. Data processing equipment 120 acquires sedimentation location data, mixing state, sedimentation environment data, cover state, environment type, and reversible storage state.

[0133] In spatial location verification, the data processing device 120 can determine whether biochar has entered a preset deposition area or passive storage area based on deposition location data, geofence data, operation coordinates, landfill area number, mine location, overburden location, construction records, or image data with timestamps.

[0134] In sedimentary environment verification, the data processing device 120 can determine whether the sedimentary environment meets the preset sealing conditions based on sedimentary environment data, cover status, mixing status, environment type, disposal records, engineering acceptance data, or on-site confirmation data. The preset sealing conditions may include entry into cover layers, landfill layers, mine backfill layers, ecological restoration cover layers, or other sedimentary environments that can reduce the risk of reverse deposition.

[0135] Passive sedimentation and sequestration verification can also include reversible storage status assessment. Reversible storage status assessment can be used to identify temporary stockpiles, easily relocatable structures, structures that may be excavated, structures that may be burned, structures that may be washed away by water, or other unstable storage conditions.

[0136] When the spatial location verification and sedimentation environment verification meet the preset pass conditions, the data processing device 120 can update the corresponding data share identifier to "passive sedimentation sealing confirmed". When the sedimentation location is unknown, the sedimentation environment evidence is insufficient, or the coverage status is incomplete, the data processing device 120 can update the corresponding data share identifier to "pending verification". When the reversible storage risk is high or the sealing conditions are not met, the data processing device 120 can update the corresponding data share identifier to "reversal risk locked, excluded, or write rejected".

[0137] Example 12: Non-sealing path identification and reversal risk locking example When the sequestration path category status is or includes a non-sequestration path identification status, the sequestration path verification includes non-sequestration path identification verification. Non-sequestration path identification verification may include at least one of prior verification consistency verification or reversal risk verification, and may be performed based on at least one of fuel use status, short-lived consumer product use status, water body release status, path association anomaly status, or disposal destination anomaly status.

[0138] For example, data processing device 120 identifies biochar entering into fuel production, short-life consumer product use, water body release paths, abnormal disposal paths, or other paths that do not meet the requirements for containment. Data processing device 120 acquires the status of fuel production use, short-life consumer product use, water body release status, abnormal status of path association, or abnormal status of disposal destination.

[0139] In reversal risk verification, data processing device 120 can identify risks such as combustion, incineration, reactivation, short-lived release, migration to unsuitable environments, entry into water bodies, reprocessing into unstable products, unverifiable disposal destination, or other reversal risks. Reversal risk verification can be performed based on usage fields, disposal destination data, transaction records, transportation trajectories, on-site verification data, external audit results, or manual review results.

[0140] In path association anomaly verification, data processing device 120 can determine whether there is a break, duplicate binding, incorrect binding, lack of traceability, abnormal time sequence, abnormal quality relationship, or abnormal delivery object between the data share identifier and the sealed carrier object identifier. Path association anomaly verification can trigger supplementary certification, manual review, status locking, or write rejection processing.

[0141] When the fuel use status indicates that the corresponding share of physical biochar production is used as fuel or enters the combustion path, the data processing device 120 can update the corresponding data share identifier to exclude or refuse to write. When the water release status, incineration risk status, or reactivation risk status indicates the existence of a reversal risk, the data processing device 120 can update the corresponding data share identifier to lock, exclude, or refuse to write to the reversal risk.

[0142] When an abnormal path association status indicates that the evidence is temporarily insufficient but there is still a possibility of supplementary verification, the data processing device 120 can update the corresponding data share identifier to pending supplementary verification and generate a supplementary verification request. When the supplementary verification shows that the corresponding physical biochar production share has entered a qualified storage path, the data processing device 120 can continue to perform storage path verification according to the corresponding storage path category status; when the supplementary verification shows that it has entered a non-storage path or its destination cannot be proven, the data processing device 120 can update it to reverse risk lock, exclude, or refuse to write.

[0143] Example 13: Status Identifier Update and Re-certification Processing Example like Figure 6 As shown, the data processing device 120 performs a status identifier update corresponding to the data share identifier based on the result of the sealing path verification. The status identifier update may include changing the data share identifier to at least one of the following: sealing path confirmed, hybrid product formed, cascade use continued tracking, long-life material sealing confirmed, passive deposition sealing confirmed, pending supplementary certification, reversal risk lock-in, exclusion or rejection of writing.

[0144] The "Storage Path Confirmed" status indicates that the corresponding physical biochar production share has passed the corresponding storage path verification. The "Mixed Product Formed" status indicates that the biochar has entered the mixed finished product batch, but subsequent delivery, application, or usage data is still pending. The "Cascade Uses Continue to Track" status indicates that the biochar has entered the primary or intermediate use, and the subsequent storage path has not yet been closed.

[0145] The "verified long-life material sequestration" status indicates that biochar has been incorporated into long-life materials and is suitable for engineering applications. The "verified passive deposition sequestration" status indicates that biochar has entered a suitable deposition environment. The "pending verification" status indicates that there are missing data, inconsistencies, or insufficient evidence, but it cannot yet be determined as non-compliant.

[0146] A reversal risk lockout status indicates the presence of risks such as combustion, reactivation, migration, excavation, short-lived release, or other reversals. An exclusion status indicates exclusion from eligible sequestration or carbon removal accounting. A write-reject status indicates that inclusion in eligible sequestration results, carbon removal results, or subsequent verification results is not permitted.

[0147] When the sealing path verification meets the preset pass conditions for the corresponding sealing path category status, the data processing device 120 changes the data share identifier to at least one of the following: sealing path confirmed, hybrid product formed, cascade use continued tracking, long-life material sealing confirmed, or passive deposition sealing confirmed.

[0148] The data processing device can determine the status identifier update based on the result type of the sealed path verification result. The result type may include at least one of the following: verification passed, evidence complete but terminal sealing not yet closed loop, subsequent destination still traceable, evidence missing, field inconsistency, abnormal path association, non-sealing purpose, reversal risk, or unprovable destination.

[0149] When the result type is "verification passed" and the corresponding sealing path category status is "direct land sealing status", the data processing device can update the data share identifier to "sealing path confirmed". When the result type is "verification passed" and the corresponding sealing path category status is "long-life material sealing status" or "passive sedimentation sealing status", the data processing device can update the data share identifier to "long-life material sealing confirmed" or "passive sedimentation sealing confirmed" respectively.

[0150] When the result type indicates that biochar has entered the blended finished product batch but final land application evidence has not yet been obtained, the data processing device can update the data share identifier to indicate that the blended product has been formed; when the result type indicates that biochar has entered the primary or intermediate use and its subsequent destination can still be traced, the data processing device can update the data share identifier to indicate that cascaded use can continue to be tracked.

[0151] When the result type indicates missing evidence, inconsistent fields, or abnormal path associations, but there is still a possibility of supplementary evidence, the data processing device can update the data share identifier to pending supplementary evidence; when the result type indicates the existence of risks such as combustion, incineration, reactivation, migration, excavation, short-lived release, water release, or other reversals, the data processing device can update the data share identifier to reversal risk lock; when the result type indicates that the corresponding physical biochar production share has entered a non-sequestration path or does not meet sequestration requirements, the data processing device can update the data share identifier to exclusion; when the result type indicates that the corresponding result is not allowed to be written into qualified sequestration results, carbon removal results, or subsequent verification results, the data processing device can update the data share identifier to refuse to write.

[0152] When the sealing path verification fails, data inconsistency occurs, there is a risk of reversal, or a non-sealing path identification result is obtained, the data processing device 120 will lock or change the data share identifier to at least one of the following: pending certificate, reversal risk lock, exclusion, or rejection of writing.

[0153] When the data share identifier is updated to a pending certification status, the data processing device 120 generates a certification request. The certification request may include at least one of the following: missing fields, abnormal fields, corresponding archived carrier object identifier, corresponding archived path category status, certification deadline, certification interface address, certification responsible entity, or certification priority.

[0154] After receiving the supplementary verification data, the data processing device 120 can re-execute the corresponding sealed path verification. When the supplementary verification is successful, the data processing device 120 updates the data share identifier to the corresponding verified status; if the supplementary verification is still incomplete, it maintains the pending verification status; if the supplementary verification shows a non-sealed path, it updates to exclude or refuse to write; if the supplementary verification shows reversal risk, it updates to reversal risk lock.

[0155] Status updates can be written to status logs, audit logs, verification platforms, carbon asset platforms, the full lifecycle dMRV module, or third-party audit systems. Status logs may include at least one of the following: data share identifier, sealed bearer identifier, sealed path category status, path verification result, status update time, update reason, supplementary certification status, exclusion reason, or reason for refusal to write.

[0156] Example 14: Complete Production Scenario like Figure 7 As shown, this embodiment provides a complete production scenario example to illustrate how the present invention, based on the prior source-side verified evidence object, further completes the data share identifier binding, sealing path category determination, sealing path verification, and status identifier update at the terminal use stage. The specific values, numbers, and times in this embodiment are only used to illustrate the implementation of the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0157] A continuous pyrolysis facility produces biochar within a monitoring cycle. The facility's source-side verification evidence generation system has generated a preceding source-side verification evidence object based on production equipment operation data, weighing data, production time windows, and quality status data. This preceding source-side verification evidence object characterizes the share of physical biochar produced within a given monitoring cycle.

[0158] For example, during the production time window from 08:00 to 12:00 on June 1, 2026, the continuous pyrolysis facility produces 10,000 kg of biochar. The source-side verification evidence generation system generates a preceding source-side verification evidence object E-001 based on the discharge weighing data, equipment operating status, production time window, operating condition data, and quality status data. The data processing device 120 generates or acquires data share identifiers DS-001 to DS-010 for the physical biochar production share represented by this preceding source-side verification evidence object, with each data share identifier corresponding to or associated with a 1,000 kg physical biochar production share.

[0159] During the packaging process, DS-001 to DS-010 are associated with packaging unit identifiers P-001 to P-010, respectively. The packaging equipment or warehousing system sends packaging time, packaging weight, packaging unit identifier, packaging equipment signature, and packaging completion status to the data processing equipment 120. Based on the above information, the data processing equipment 120 establishes an association between the data share identifier and the packaging unit identifier.

[0160] When P-001 to P-004 are loaded into transport unit T-001 and P-005 to P-010 are loaded into transport unit T-002, the data processing device 120 further establishes a multi-level association between the data share identifier, packaging unit identifier, and transport unit identifier. This multi-level association can be stored in an association table, index record, hash pointer, electronic waybill, or warehousing and logistics system record.

[0161] In scenario A, the packaging units corresponding to DS-001 to DS-003 are transported to farm plot F-01 and applied to the land by the application equipment. The data processing equipment 120 acquires transportation data, delivery data, terminal operation object identification, operation location data, operation time data, application area data, weight loss curve data, user confirmation data, geofence data, and timestamped image data.

[0162] Data processing device 120 determines the direct land storage status corresponding to DS-001 to DS-003 and performs quality conservation verification and spatial location verification. When the outbound quality, delivery quality, and application weight reduction data meet the preset consistency conditions, and the operation location falls within the geofence area, data processing device 120 updates DS-001 to DS-003 to confirm the storage path.

[0163] In scenario B, packaging units corresponding to DS-004 to DS-006 are delivered to soil amendment product manufacturing node M-01 and mixed with compost, minerals, and organic fertilizer to form finished product batch B-100. The manufacturing execution system sends the product manufacturing node identifier, feeding batch identifier, finished product batch identifier, biochar blending ratio, ratio benchmark, finished product outbound status, and product usage fields to the data processing device 120.

[0164] Data processing device 120 determines the land application status of the mixed products corresponding to DS-004 to DS-006, and performs quality conservation verification, composition ratio verification, delivery object verification, and finished product batch attribution verification. When the feed quality and the attributable biochar quality in the finished product batch meet the preset consistency conditions, and the finished product use field shows land application, data processing device 120 updates DS-004 to DS-006 to indicate that the mixed product has been formed. If the land application record of finished product batch B-100 is subsequently received, the corresponding data share identifier can be further updated to indicate that the sealing path has been verified.

[0165] In scenario C, the packaging units corresponding to DS-007 to DS-008 are delivered to the building material manufacturing node C-01 and incorporated into the building material batch CM-200 as filler. The project management system then sends the project application object identifier, construction location data, project ownership data, and material curing status.

[0166] Data processing device 120 determines the long-life material storage status corresponding to DS-007 to DS-008 and performs quality conservation verification and engineering application attribution verification. When the formula ratio, finished material batch, and engineering application object identifier of the building material manufacturing node meet the preset attribution conditions, and the material curing status shows that it has been cured or installed, data processing device 120 updates DS-007 to DS-008 to confirm that the long-life material storage has been verified.

[0167] In scenario D, the packaging unit corresponding to DS-009 enters the first application of filter media or adsorbent material. Data processing device 120 acquires the first application data, intermediate product data, subsequent destination data, or disposal destination data, and determines the cascade application tracking status of DS-009. When the subsequent destination is not yet closed-loop but a traceable chain of evidence still exists, data processing device 120 updates DS-009 to a cascade application and continues tracking; when subsequent supplementary data indicates that it has entered a qualified land storage, long-life material storage, or passive sedimentation storage path, data processing device 120 can further perform corresponding storage path verification and update it to the corresponding confirmed status.

[0168] In scenario E, a portion of DS-010 or another data share identifier corresponding to a packaging unit enters a passive storage environment such as deposition, overburden, landfill, mine backfill, ecological restoration overburden, or other passive storage environment. Data processing device 120 acquires deposition location data, mixing state, deposition environment data, or reversible storage state, and determines the corresponding data share identifier to be in a passive deposition storage state. When spatial location verification and deposition environment verification meet preset pass conditions, data processing device 120 updates the corresponding data share identifier to confirm passive deposition storage.

[0169] In scenario F, some packaging units are recorded as being used for fuel production, or lack a delivery recipient and their transport trajectory is inconsistent with the preset path. Data processing device 120 can determine that the corresponding data share identifier is in a non-sealed path identification state, and perform non-sealed path identification verification or reversal risk verification based on the fuel production use status, path association anomaly status, or reversal risk status. For data share identifiers indicating fuel production use, data processing device 120 can update them to exclude or refuse to write; for data share identifiers that temporarily lack evidence but still have the potential for supplementary verification, data processing device 120 can update them to pending supplementary verification and generate a supplementary verification request.

[0170] Through the above processing, the share of physical biochar production represented by the same prior source-side verification evidence object E-001 can be split, mixed, diverted, tracked, and verified at the end-use stage. The data processing device 120 does not simply assume all source-side output has been sealed; instead, it performs path category determination, path verification, and status identifier update based on the sealing carrier object and sealing path data corresponding to each data share identifier, thereby reducing the risks of false sealing, duplicate accounting, path breakage, and reversal.

[0171] Example 15: Interface Example with Other Verification Modules like Figure 8 As shown, the data processing device 120 of the present invention can serve as an end-use evidence generation and binding node, interacting with one or more other verification modules. These other verification modules may include a source-side verification evidence generation module, a raw material verification and binding module, a dry-basis quality correction module, a sample chain and representativeness verification module, a full lifecycle dMRV module, a warehousing and logistics module, a manufacturing execution module, an engineering application management module, a carbon asset module, or a third-party audit module.

[0172] Data provided to this invention by other verification modules can serve as source-side trusted state data, sealed path data, path evidence fields, or a basis for state updates. This invention does not require other verification modules to employ specific algorithms, data structures, or deployment methods.

[0175] The data provided by the raw material verification and binding module is used to enhance the credibility of the preceding state or audit traceability. The core processing of this invention is still the binding of the data share identifier and the sealed carrier object identifier in the end-use stage, the determination of the sealed path category, the path verification, and the status identifier update.

[0177] This invention does not limit the specific calculation method of dry basis mass. Mass conservation verification can be performed based on wet weight, dry basis mass, corrected mass, finished product attribution mass, or a combination thereof.

[0178] The data processing device 120 is communicatively connected to the sample chain and representative verification module. The sample chain and representative verification module can provide at least one of the following: sample identification, test report identification, sample attribution, sampling coverage, representative status data, test result status, or finished product batch association data. In mixed product land application, long-life material storage, or passive deposition storage paths, the data processing device 120 can reference the test result status or representative status data provided by the sample chain and representative verification module to assist in determining whether the finished product batch, material batch, or deposition object meets the preset storage path verification conditions.

[0179] The data from the sample chain and the representative verification module can be used as one of the path evidence fields. This invention is not necessarily limited to specific sampling methods, detection items or representative algorithms.

[0180] The data processing device 120 is communicatively connected to the full lifecycle dMRV module.

The data processing device 120 can output at least one of the following to the carbon asset platform or auditing system: data share identifier, sealed path category status, path verification result, status identifier update result, evidence field index, supplementary evidence status, reason for exclusion or rejection of writing, and audit traceability data. Based on the above output data, the carbon asset platform or auditing system can determine whether a certain data share identifier can be included in carbon removal accounting, whether it should be suspended, whether it should be excluded, or whether further manual auditing is required.

[0186] The aforementioned interfaces can be implemented via API, message queues, database synchronization, file import, event notification, edge gateway forwarding, blockchain records, electronic signature records, hash pointers, or combinations thereof. Interface data formats may include JSON, XML, CSV, database records, binary messages, electronic forms, electronic waybills, audit logs, or other machine-readable formats.

[0187] Through the aforementioned interfaces, this invention can connect data between source-side verification, raw material binding, quality correction, sample representativeness, lifecycle accounting, warehousing and logistics, manufacturing execution, engineering applications, and carbon asset platforms. At the same time, it still uses data share identification binding, storage path category determination, storage path verification, and status identification update at the end-use stage as the core processing path, thereby forming an end-to-end biochar carbon removal verification closed loop.

[0188] Example 16: System Example like Figure 1 As shown, this embodiment provides a biochar carbon removal verification data processing system 100 based on physical-digital identity. The system 100 may include a data acquisition module 121, an association processing module 122, a path category status determination module 123, a sealed path verification module 124, and a status identifier update module 125.
