Description

Technical Field

[0001] The present invention relates to the field of computer technology, and particularly to a method, a system, a server and a storage medium for signing an inheritance distribution agreement. Background Art

[0002] A blockchain is a distributed ledger, a technical solution for collectively maintaining a reliable database in a decentralized and trustless manner.

[0003] A smart contract is a set of agreements defined, propagated, verified or executed in digital form, including the protocols on which the contract parties can execute these agreements. Smart contracts allow for trusted transactions without a third party, and these transactions are traceable and irreversible.

[0004] Currently, the inheritance distribution adopts traditional methods, such as usually notifying orally, or signing a distribution agreement with a law firm and informing the relevant interested parties through the law firm. The oral method usually lacks the effect of evidence fixation and is prone to the relevant interested parties refusing to admit it; while the distribution agreement signed by the law firm is stored centrally, there is a risk of loss and being tampered with, which is prone to continuous inheritance disputes in the later stage and the disadvantage of high judicial costs.

[0066] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0067] The terms "first", "second", etc. in the specification and claims of the present application and the above accompanying drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0068] Referring to "embodiment" in the present application means that a specific feature, structure or characteristic described in combination with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0069] Blockchain is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, and encryption algorithms. Blockchain, in essence, is a decentralized database, a series of data blocks generated by using cryptographic methods. Each data block contains information about a batch of network transactions, used to verify the validity of the information (anti-counterfeiting) and generate the next block. Blockchain can include the blockchain underlying platform, the platform product service layer, and the application service layer.

[0070] The blockchain underlying platform can include processing modules such as user management, basic services, smart contracts, and operation monitoring. Among them, the user management module is responsible for the identity information management of all blockchain participants, including maintaining the generation of public and private keys (account management), key management, and the maintenance of the correspondence between the real identity of the user and the blockchain address (permission management). And under authorized circumstances, it supervises and audits the transaction situations of certain real identities, providing the rule configuration for risk control (risk control audit); the basic service module is deployed on all blockchain node devices, used to verify the validity of business requests, and after reaching a consensus on valid requests, record them on the storage. For a new business request, the basic service first performs interface adaptation parsing and authentication processing (interface adaptation), then encrypts the business information through the consensus algorithm (consensus management), and after encryption, transmits it to the shared ledger completely and consistently (network communication), and performs record storage; the smart contract module is responsible for the registration and issuance of contracts, as well as contract triggering and contract execution. Developers can define contract logic through a certain programming language, publish it to the blockchain (contract registration), and according to the logic of the contract terms, call keys or other events to trigger execution, complete the contract logic, and at the same time also provide functions for contract upgrade and cancellation; the operation monitoring module is mainly responsible for the deployment, configuration modification, contract setting, cloud adaptation during the product release process, and the visual output of the real-time state during product operation, such as: alarming, monitoring network conditions, monitoring the health status of node devices, etc.

[0071] The platform product service layer provides the basic capabilities and implementation frameworks of typical applications. Developers can build on these basic capabilities and overlay the characteristics of the business to complete the blockchain implementation of the business logic. The application service layer provides application services based on the blockchain solution for business participants to use.

[0072] Please refer to Figure 1 , Figure 1 which provides a schematic diagram of a method for signing an inheritance distribution protocol for the embodiments of this application. As Figure 1As shown in the figure, it may include an inheritance distribution agreement signing server 101, a law firm platform 102, and an inheritance distributor 103. Among them, the inheritance distribution agreement signing server 101 receives a first transaction request sent by the law firm platform 102, and the first transaction request carries a digital signature of the first inheritance distribution agreement data; the inheritance distribution agreement signing server 101 verifies the digital signature of the first inheritance distribution agreement data. If the verification passes, the first transaction is chained and the first transaction is executed; the inheritance distribution agreement signing server 101 reaches a consensus on the result of the execution of the first transaction and returns the result of the execution of the first transaction to the law firm platform 102; when the inheritance distribution agreement signing server 101 receives a second transaction request sent by the inheritance distributor 103, it verifies the digital signature of the second inheritance distribution agreement data. If the verification passes, the second transaction is chained and the second transaction is executed, where the second transaction request carries the digital signature of the second inheritance distribution agreement data; the inheritance distribution agreement signing server 101 reaches a consensus on the result of the execution of the second transaction, records the signing status of the inheritance distribution agreement as effective, and returns the result of the execution of the second transaction to the inheritance distributor 103 and / or the law firm platform 102.

[0073] Through the embodiments of the present application, the digital signatures of the inheritance distribution agreements of the received law firm platform and the inheritance distributor are both verified, and each transaction is executed after passing the verification. When the execution results are all successful, the signing status of the inheritance distribution agreement is recorded as effective. By adopting this means, the fairness and accuracy of the inheritance distribution agreement signing process can be ensured, and at the same time, the above process is implemented on the blockchain, making the inheritance distribution agreement not easy to be lost and not easy to be tampered with, reducing the problem of inheritance disputes in the later stage.

[0074] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of a method for signing an inheritance distribution agreement provided by the embodiments of the present application. As Figure 2 shown, it may include steps 201-205, which are specifically as follows:

[0075] 201. Receive a first transaction request sent by a first platform, where the first transaction request carries a digital signature of the first inheritance distribution agreement data;

[0076] Among them, the first platform in the embodiments of the present application may be a law firm platform or other platforms with certain legal effect, which is not specifically limited here.

[0077] 202. Verify the digital signature of the first inheritance distribution agreement data. If the verification passes, chain the first transaction and execute the first transaction;

[0078] Among them, the first inheritance distribution agreement data signature includes the public key of the first inheritance distribution agreement data signature and the private key of the first inheritance distribution agreement data signature.

[0079] The above verification of the first inheritance distribution agreement data signature is to compare whether the public key of the first inheritance distribution agreement data signature and the private key of the first inheritance distribution agreement data signature correspond; if they correspond, the verification passes. The above correspondence can be exactly the same, or follow a preset algorithm mechanism, etc., which is not specifically limited here.

[0080] 203. Conduct consensus on the result of the execution of the first transaction and return the result of the execution of the first transaction to the first platform;

[0081] The above result of the execution of the first transaction can be success or failure.

[0082] For example, it can be set that when the result of the execution of the first transaction is successful, step 204 can be performed. Among them, when the result of the execution of the first transaction is successful, record the signing status of the inheritance distribution agreement as signed by the law firm.

[0083] 204. When receiving the second transaction request sent by the second platform, verify the second inheritance distribution agreement data signature. If the verification passes, chain the second transaction and perform the execution of the second transaction, where the second transaction request carries the second inheritance distribution agreement data signature;

[0084] The second platform can refer to the inheritance distributor.

[0085] 205. Conduct consensus on the result of the execution of the second transaction, record the signing status of the inheritance distribution agreement as effective, and return the result of the execution of the second transaction to the second platform and / or the first platform.

[0086] Here, the result of the execution of the second transaction can also only refer to success. At this time, record the signing status of the inheritance distribution agreement as effective. That is, when it is ensured that the law firm has signed, the inheritance distributor has also signed, and all aspects have been verified and are successful, then confirm that the signing status of the inheritance distribution agreement is effective.

[0087] Through the embodiments of the present application, verify the inheritance distribution agreement data signatures of both the law firm platform and the inheritance distributor received, and perform the execution of each transaction after passing the verification. When the execution results are all successful, record the signing status of the inheritance distribution agreement as effective. By adopting this means, the fairness and accuracy of the signing process of the inheritance distribution agreement can be ensured, and at the same time, the above process is implemented on the blockchain, making the inheritance distribution agreement not easy to be lost and not easy to be tampered with, reducing the problem of inheritance disputes in the later stage.

[0088] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of a method for signing an inheritance distribution agreement provided by an embodiment of this application. As Figure 3 shown, it may include steps 301-309, specifically as follows:

[0089] 301. Receive a first transaction request sent by a first platform, where the first transaction request carries a digital signature of the first inheritance distribution agreement data;

[0090] Among them, the digital signature of the first inheritance distribution agreement data contains the public key of the first transaction; the first transaction request also carries information about the inheritance distributor, law firm information, smart contract information, inheritance distribution agreement, digest hash of the law firm's enterprise certificate, and the public key of the law firm's enterprise certificate.

[0091] For example, the law firm signs the digital signature of the inheritance distribution agreement through the platform in the form of a transaction and sends it to the blockchain. The transaction content mainly includes the inheritance distributor ID, law firm ID, deployed smart contract address ID, inheritance distribution agreement, agreement number, digest hash of the law firm's enterprise certificate, and public key, etc.

[0092] 302. Verify the digital signature of the first inheritance distribution agreement data. If the verification passes, then put the first transaction on the chain;

[0093] After the inheritance distribution agreement signing server (such as a blockchain platform) receives the above transaction, it verifies the legality of the transaction signature. If the verification fails, it returns a verification failure result; if the verification is successful, the blockchain consensus node packages the above transaction into a block for execution and consensus.

[0094] 303. Confirm whether the smart contract has been deployed according to the smart contract information;

[0095] 304. If it has been deployed, query whether there is a certificate corresponding to the digest hash of the law firm's enterprise certificate;

[0096] 305. If there is, confirm whether the public key of the law firm's enterprise certificate is consistent with the public key of the first transaction;

[0097] 306. If they are consistent, record the signing status of the inheritance distribution agreement as signed by the first platform, and obtain the transaction hash of the first transaction; and write the information about the inheritance distributor, law firm information, inheritance distribution agreement, and the signing status of the inheritance distribution agreement into the smart contract;

[0098] Among them, the transaction execution process includes:

[0099] Query whether the smart contract is deployed by the smart contract address ID. If it is not deployed, return a failure result of the execution.

[0100] If it is deployed, query the certificate by the enterprise certificate digest hash. If the query is successful, compare whether the public key in the certificate is the same as the public key information in the transaction. Only when all the above verifications are successful, set the signing status of the inheritance distribution agreement as signed by the law firm, and use the agreement number as the keyword Key, and write the inheritance assignee ID, law firm ID, inheritance distribution agreement, signing status, and the law firm's signing transaction hash and other data as values Value into the smart contract.

[0101] 307. Consensus on the result of the execution of the first transaction, and return the result of the execution of the first transaction to the first platform.

[0102] After the blockchain platform reaches a consensus on the execution result of the above transaction and writes it into the ledger, return the transaction and the transaction execution result to the law firm platform so that the law firm platform can inform relevant signers, etc.

[0103] 308. When receiving a second transaction request sent by the second platform, verify the signature of the second inheritance distribution agreement data. If the verification passes, put the second transaction on the chain and perform the second transaction execution, where the second transaction request carries the signature of the second inheritance distribution agreement data.

[0104] Among them, the second transaction request also carries the user certificate digest hash, the public key of the user certificate, the inheritance distribution agreement, the smart contract information, and the transaction hash of the second transaction. The signature of the second inheritance distribution agreement data contains the public key of the second transaction.

[0105] The operation of putting the second transaction on the chain and performing the second transaction execution includes:

[0106] Record the second transaction in each block.

[0107] Query whether there is a certificate corresponding to the user certificate digest hash.

[0108] If it exists, confirm whether the public key of the user certificate is the same as the public key of the second transaction.

[0109] If they are the same, confirm whether the inheritance distribution agreement exists.

[0110] If the inheritance distribution agreement exists, confirm whether the transaction hash of the second transaction is the same as the transaction hash of the first transaction.

[0111] If they are the same, confirm whether the signing status of the inheritance distribution agreement is signed by the law firm.

[0112] If the law firm has signed the contract, update the signing status of the inheritance distribution agreement to effective and write it into the smart contract.

[0113] That is, when it is ensured that the law firm has signed the contract, the inheritance distributor has also signed the contract, and all aspects have been verified and are successful, then confirm that the signing status of the inheritance distribution agreement is effective.

[0114] Specifically, for example, the inheritance distributor can query whether the specific content of the agreement on the chain is consistent with the content displayed on the law firm platform through the above agreement number. If they are consistent, the inheritance distributor digitally signs the inheritance distribution agreement and sends it to the blockchain in the form of a transaction. The transaction content can include the inheritance distributor ID, law firm ID, smart contract address ID, inheritance distribution agreement, agreement number, user certificate and public key information, and the transaction hash of the first transaction received through the law firm platform, etc.

[0115] Among them, after the blockchain platform receives the above transaction, it verifies the legality of the transaction signature. For example, by comparing the public key and private key of the signature, if the comparison is successful, it is confirmed that the verification is successful. When the verification is successful, the blockchain consensus node executes and reaches a consensus by packing the above transaction into a block;

[0116] Among them, the transaction execution process includes:

[0117] Query whether the smart contract is deployed through the smart contract address ID. If it is not deployed, return an execution failure result; if it is deployed, query the certificate through the user certificate digest hash. When the certificate exists, compare whether the public key in the certificate is the same as the public key information in the transaction. If they are the same, then verify whether the protocol exists; if it exists, query the specific content of the protocol through the protocol number, and compare whether the law firm signing transaction hash in the protocol content stored in the above smart contract is the same as the transaction hash in the inheritance distributor signing transaction content; if they are the same, then verify whether the signing status is that the law firm has signed the contract. If so, verify whether the inheritance distributor ID and law firm ID are the same. If they are the same, then verify whether the inheritance distribution agreement is the same. Only when all the above verifications pass, update the protocol content, update the signing status to effective, add the inheritance distributor signing transaction hash, and write it into the smart contract. Among them, the above verification steps do not limit the sequence of each verification process.

[0118] 309. Reach a consensus on the result of the execution of the second transaction, record the signing status of the inheritance distribution agreement as effective, and return the result of the execution of the second transaction to the second platform and / or the first platform.

[0119] Perform blockchain consensus on the execution results of the above transactions. After reaching a consensus, write the results to the ledger and return the results to the estate distributor, or the law firm platform, etc., to inform the relevant parties.

[0120] Through the embodiments of the present application, the digital signatures of the estate distribution agreement data received from the law firm platform and the estate distributor are both verified, and each transaction is executed after passing the verification. When the execution results are all successful, the signing status of the estate distribution agreement is recorded as effective. By adopting this method, the fairness and accuracy of the signing process of the estate distribution agreement can be ensured. At the same time, the above process is implemented on the blockchain, making the estate distribution agreement not easy to be lost and not easy to be tampered with, reducing the problem of late estate disputes.

[0121] Please refer to Figure 4 , Figure 4 which is a schematic flowchart of a method for signing an estate distribution agreement provided by an embodiment of the present application. As Figure 4 shown, it may include steps 401-409, specifically as follows:

[0122] 401. Receive a first transaction request sent by a first platform, where the first transaction request carries a first digital signature of estate distribution agreement data;

[0123] Wherein, before step 401, the method further includes:

[0124] Receive a digital signature of a law firm enterprise certificate sent by a third platform, and verify the digital signature of the law firm enterprise certificate;

[0125] The third platform can be any certification authority, etc.

[0126] If the digital signature verification of the law firm enterprise certificate passes, perform a digest hash calculation on the law firm enterprise certificate to obtain the digest hash of the law firm enterprise certificate;

[0127] Consensus on the digest hash of the law firm enterprise certificate and the law firm enterprise certificate and upload them to the blockchain.

[0128] For example, before the transaction, the law firm platform conducts qualification upload to the blockchain.

[0129] Specifically, the law firm platform locally generates an asymmetric public-private key pair, signs the identity of the law firm platform and the service qualification information of the law firm platform authoritatively issued through the private key, and then applies for a certificate from a CA institution such as the public key, the law firm platform information, and the signature.

[0130] After the CA institution conducts real-name authentication on the received application, it issues an enterprise certificate to the law firm platform and packages the certificate into a transaction and uploads it to the blockchain.

[0131] After the blockchain receives a transaction, it verifies the legality of the transaction, which may include verifying the digital signature of the transaction by a CA institution. After passing the verification, the virtual machine is called to execute the transaction.

[0132] During the execution process, the smart contract is called to open the certificate storage. First, a digest hash calculation is performed on the certificate, and then it is queried whether the certificate already exists through the digest hash. If it exists, an execution failure result is returned; if not, the verification is successful. After passing the verification, the digest hash is used as the keyword Key, and the certificate is written into the smart contract as the value Value.

[0133] The above verification result is subject to blockchain consensus, and after reaching a consensus, it is written into the ledger.

[0134] The above result of being recorded on the chain and the certificate digest hash are returned to the CA institution, so that the CA institution can return the enterprise certificate and the certificate digest hash to the law firm platform, and the law firm platform can store the enterprise certificate and the certificate digest hash.

[0135] On the other hand, before step 401, the method further includes:

[0136] Receiving the digital signature of the user certificate sent by the third platform and verifying the digital signature of the user certificate;

[0137] If the verification of the digital signature of the user certificate passes, a digest hash calculation is performed on the user certificate to obtain the user certificate digest hash;

[0138] The user certificate digest hash and the user certificate are subject to consensus and recorded on the chain.

[0139] For example, before the transaction, the identity of the estate distributor is also recorded on the chain.

[0140] Specifically, after the estate distributor passes the platform real-name authentication, the platform generates an asymmetric public-private key pair for the estate distributor, signs the identity of the estate distributor with the private key, and then applies for a certificate from the CA institution with the public key, the identity of the estate distributor, and the signature.

[0141] After the CA institution conducts real-name authentication on the received application, it issues a user certificate to the estate distributor and packages the certificate into a transaction and records it on the chain.

[0142] After the blockchain receives a transaction, it verifies the legality of the transaction, mainly the digital signature of the transaction by the CA institution; after passing the verification, the virtual machine is called to execute the transaction.

[0143] Among them, during the execution process, the smart contract is called to start certificate storage. First, a digest hash calculation is performed on the certificate, and then it is queried whether the certificate already exists through the digest hash. If it exists, an execution failure result is returned; if not, it is confirmed that the verification passes. After the verification passes, the digest hash is used as the keyword Key, and the certificate is used as the value Value and written into the smart contract.

[0144] The blockchain consensus is performed on the above verification result, and after reaching a consensus, it is written into the ledger.

[0145] The above chain-upload result and the certificate digest hash are returned to the CA institution, so that the CA institution can return the user certificate and the certificate digest hash to the platform, so that the platform can store the user certificate and the certificate digest hash, and inform the estate distributor. The estate distributor can choose to store the user certificate and the certificate digest hash.

[0146] Before step 401, the method further includes:

[0147] Receiving a third transaction request sent by the first platform, the third transaction request carrying the smart contract data for signing the estate distribution agreement, the digest hash of the law firm enterprise certificate, the public key of the law firm enterprise certificate, and the public key of the third transaction;

[0148] Generating a smart contract hash digest according to the smart contract data for signing the estate distribution agreement, and recording the smart contract hash digest as smart contract information;

[0149] Confirming whether the smart contract has been deployed according to the smart contract information;

[0150] If the smart contract has not been deployed, query whether there is a certificate corresponding to the digest hash of the law firm enterprise certificate;

[0151] If it exists, confirm whether the public key of the law firm enterprise certificate is consistent with the public key of the third transaction;

[0152] If they are consistent, perform consensus on the smart contract information and the smart contract data for signing the estate distribution agreement and upload them to the chain.

[0153] Furthermore, before the above transaction, it also includes that the law firm platform deploys a smart contract for signing the estate distribution agreement.

[0154] Specifically, the law firm platform deploys the smart contract for signing the estate distribution agreement to the blockchain in the form of a transaction through the platform. The transaction content includes the smart contract for signing the estate distribution agreement, the platform certificate digest hash, and the public key.

[0155] After the blockchain platform receives a transaction, it verifies the legality of the transaction signature, such as by checking whether the public key and private key contained in the signature correspond; if the verification fails, it returns a verification failure result; if the verification is successful, the blockchain consensus node packages the above transaction into a block for execution and consensus.

[0156] Among them, the above transaction execution process includes:

[0157] Generate a hash digest from the above smart contract data and use the hash digest as the contract address ID.

[0158] Check whether the contract has been deployed through the contract address ID. If so, return an execution failure result. If the contract corresponding to the contract address ID has not been deployed, confirm that the verification is successful; then further query the certificate through the platform certificate digest hash. If the query is successful, compare whether the public key in the certificate is the same as the public key information in the transaction. If they are not the same, return an execution failure result; if they are the same, write the above smart contract data as the content into the cache using the contract address ID as the keyword. Among them, when and only when all the above verifications are successful, write the above smart contract data as the content into the cache. Among them, the above verification process does not limit the order.

[0159] Then, the blockchain platform conducts consensus on the above transaction execution result and writes the transaction and the above smart contract into the ledger.

[0160] The blockchain platform returns the transaction, the transaction execution result, and the above smart contract address ID to the platform so that the platform can store the transaction, the transaction execution result, and the smart contract address ID used to sign the agreement.

[0161] After the qualification of the above law firm platform is uploaded to the chain and the identity of the estate distributor is also uploaded to the chain, and after the law firm platform deploys the smart contract used to sign the estate distribution agreement, the estate distribution agreement can be signed.

[0162] 402. Verify the signature of the first estate distribution agreement data. If the verification passes, upload the first transaction to the chain and perform the first transaction execution;

[0163] 403. Conduct consensus on the result of the first transaction execution and return the result of the first transaction execution to the first platform;

[0164] 404. When receiving the second transaction request sent by the second platform, verify the signature of the second estate distribution agreement data. If the verification passes, upload the second transaction to the chain and perform the second transaction execution, where the second transaction request carries the signature of the second estate distribution agreement data;

[0165] 405. Consensus is reached on the result of the execution of the second transaction, the signing status of the inheritance distribution agreement is recorded as effective, and the result of the execution of the second transaction is returned to the second platform and / or the first platform;

[0166] 406. Obtain the agreement terms in the inheritance distribution agreement;

[0167] After the agreement becomes effective, the agreement terms in the inheritance distribution agreement can be obtained.

[0168] 407. Generate corresponding task requests according to the agreement terms;

[0169] For example, the inheritance distribution agreement signing server generates corresponding operation task requests according to the signed agreement terms. Specifically, if the agreement stipulates that after the death of the inheritance distributor, the bank funds will be transferred to the beneficiary according to the distribution plan. Then the task request that can be generated is: Request the bank to transfer xxx amount of funds to the beneficiary account xxx.

[0170] 408. Send the task request to the task node to execute the task request;

[0171] The inheritance distribution agreement signing server can send the above task request to the corresponding task node, such as a certain bank, etc.

[0172] 409. Send the task execution result to the smart contract to verify whether the agreement terms in the inheritance distribution agreement are correctly fulfilled, and chain the task execution result.

[0173] Among them, steps 406-409 can be implemented on the oracle. Among them, the oracle is a platform that provides external information and is itself a kind of smart contract, providing a link between the blockchain and the real world. After the inheritance distribution agreement becomes effective, the smart contract ensures the automatic execution of the signed agreement terms through the oracle. The implementation process of the oracle can be as Figure 5 shown:

[0174] The smart contract generates corresponding operation task requests based on the signed agreement terms. For example, after the death of the inheritance distributor, the bank funds will be transferred to the beneficiary according to the distribution plan.

[0175] The smart contract notifies the oracle smart contract of the operation task request. The oracle smart contract creates the corresponding operation task and notifies the oracle task node deployed outside the blockchain;

[0176] After receiving an operation task, the oracle task node will execute the operation task as required. Among them, the oracle node feeds back the bank fund transfer data to the oracle smart contract. The oracle smart contract stores the received bank fund transfer data. Then, the oracle smart contract notifies the smart contract of the bank fund transfer data. After receiving the bank fund transfer data, the smart contract verifies whether the terms of the signed inheritance distribution agreement are correctly fulfilled; if not, it updates the agreement fulfillment status and relevant certificates according to the agreement number, that is, the bank fund transfer data.

[0177] Among them, the beneficiary and the law firm can query the status of agreement performance through a blockchain browser, etc., which is very convenient.

[0178] Through the embodiments of the present application, by verifying the signature of the inheritance distribution agreement data received from the first platform and the second platform, and performing the execution of each transaction after passing the verification. When the execution results are all successful, the signing status of the inheritance distribution agreement is recorded as effective. By adopting this means, the fairness and accuracy of the inheritance distribution agreement signing process can be ensured. At the same time, the above process is implemented on the blockchain, making the inheritance distribution agreement not easy to be lost and not easy to be tampered with, reducing the problem of inheritance disputes in the later stage.

[0179] On the other hand, this solution provides a credible inheritance distribution agreement based on smart contract and oracle technology. By leaving a trace of the inheritance distribution plan on the blockchain, the complete process of the inheritance distributor and the lawyer signing the distribution agreement is closed-loop traced through the smart contract, and the content of the distribution agreement is automatically fulfilled through the oracle method, reducing the disputes and judicial costs brought by the inheritance distribution interests, and contributing to the promotion of social harmony.
