Rather, embodiments of the present invention may be applied to any scenario where applicable.

Fig. 2 schematically shows a flow diagram of a transaction processing method according to an embodiment of the invention.

According to an embodiment of the present disclosure, the transaction processing method may be applied to a blockchain node in a blockchain network, as shown in fig. 2, the transaction processing method according to an embodiment of the present invention includes operations S210 to S220.

In operation S210, a transaction request for requesting a transaction target object sent by a client is obtained, where the transaction request carries a digital asset transaction amount.

According to the embodiment of the invention, a user can purchase the encrypted currency of the block chain platform in advance through a client, for example, the legal currency is converted into the encrypted currency of the block chain platform through an off-chain recharging system and an off-chain exchange system, and the encrypted currency owned by the user is the digital asset of the user. When the user purchases the target object, the user needs to pay the corresponding encryption currency of the blockchain platform to complete the purchase transaction.

In operation S220, in response to the transaction request, according to a target intelligent contract corresponding to the target object, the digital asset transaction amount carried in the transaction request is allocated to the at least two block chain account numbers, and a transaction record is generated, where the target intelligent contract is agreed with an asset allocation proportion of the at least two block chain account numbers.

According to an embodiment of the present invention, the at least two blockchain account numbers may include a blockchain account number of an issuing end of the target object and a blockchain account number of an initiating end of the target object. Of course. The blockchain account agreed in the smart contract according to the present disclosure is not limited thereto, and may also include a public utility account, for example, and assets in the public utility account may be used for a utility.

According to the embodiment of the invention, the asset allocation proportion of at least two block chain account numbers agreed in the target intelligent contract is predetermined, and the asset allocation proportion of each block chain account number can be set according to the agreement between parties capable of participating in asset allocation, such as an initiating party and a issuing party.

According to the embodiment of the invention, taking the game a with the target object as the new development as an example, the issuing end of the game can be a game issuer, the developing end of the game can be a game developer, and the blockchain network can be used as a blockchain game platform. The block link points in the block chain network may be deployed as a federation chain. The alliance chain can provide corresponding web plug-ins or application programs for game developers to conduct contract management, provide corresponding web plug-ins for user clients to conduct currency transaction, and provide a blockchain browser to conduct data export and show detailed accounts.

Specifically, for example, user tony purchases game a via a client and downloads it, resulting in a transaction for game a. The blockchain links in the blockchain network will automatically enter the blockchain account of the game developer assigned by game a according to the intelligent contract created by game a, for example, 70% of the digital asset transaction amount and 30% of the digital asset transaction amount will automatically enter the blockchain account of the game issuer assigned by game a according to the asset allocation proportion. And, the block link point generates a Transaction record Transaction a, and the Transaction Hash (i.e. Hash value) is the Transaction a Hash. The user tony may obtain a non-homogenous unique pass a1 that is unique to his game a.

According to the embodiment of the invention, the transaction records are managed by decentralized management of the block chain network, the asset allocation proportion of at least two block chain account numbers is agreed in the target intelligent contract, and the transaction amount of each time is allocated to different block chain account numbers.

According to embodiments of the invention, deploying intelligent contracts to blockchain networks eliminates centrally generated sales shares and management costs for crowd funding situations. Meanwhile, the centralized management and sales and crowd funding records are removed, and the fairness, the justness and the transparency of the product can be ensured. The fairness of all information may facilitate more developers to participate in the distribution of the distribution platform according to embodiments of the present invention. For crowd funding projects, more users can be promoted to participate in development and funding of the projects, and investments of the projects interested by the users can be relieved.

The method shown in fig. 2 is further described with reference to fig. 3-8 in conjunction with specific embodiments.

FIG. 3 schematically shows a flow diagram for deploying an intelligent contract, according to an embodiment of the invention.

As shown in FIG. 3, deploying a smart contract includes operations S310-S320.

In operation S310, a deployment request sent by a development end for requesting to deploy an intelligent contract is obtained, where the deployment request carries contents of the intelligent contract requested to be deployed, and the intelligent contract requested to be deployed is signed by the development end in advance.

In operation S320, in response to the deployment request, consensus verification is performed on the smart contract requested to be deployed.

According to an embodiment of the present invention, specifically, for example, the content of the game smart contract may include the following content. // issuing a smart contract for a game:

the game publisher distributes proportional playfacecent; game developers distribute proportion gamePercent; game developer blockchain address identity gameSignAddress;

uint signResult＝publish(platPercent，gamePercent，gameSignAddress)；

obtaining respective related information according to the result of the signResult, wherein the signResult can also comprise a unique ID of the gameId game, an account address of a placeddress game publisher, a public key of the placepubic game publisher, a private key of the placePrivate game publisher, an account address of a gameAdress game developer, a public key of the gamePublic game developer and a private key of the gamePrivate game publisher. Wherein, different private keys can be obtained by using the private keys of respective multi-account to decrypt.

According to the embodiment of the invention, in the intelligent contract, when each game developer issues a new game, the intelligent contract can be called in a multi-sign mode to generate a latest exclusive game blockchain information set of the game. The exclusive game block chain information set comprises a game publisher and a public and private key corresponding to a corresponding transfer block chain account number of the game developer and a block chain account number of the game developer in the game, the private key is stored by the game developer, and the public key is visible to the whole network through inquiring account information.

According to an embodiment of the invention, the blockchain account number includes a private key and a blockchain address, and is generated by a third party or a user based on an elliptic curve cryptography algorithm. The user blockchain private key must be kept by the user himself. The private key can derive a blockchain address, which cannot. When a user transaction initiates a verification transaction, a private key is required to be used for signature verification, signature verification parameters cannot deduce a user private key, but a user block chain address can be deduced, and other private keys cannot deduce the user block chain address. The blockchain address is to conform to the blockchain etherhouse address format.

According to an embodiment of the present invention, for example, the user block chain address may be: 0x4f935600dcb7c4c7de17d4611113e3a5b8a718ea, the private key for the blockchain address may be 2fb7fd4eb832bbb06ca3d04201d4c06a243aea6eec8214dbbe7626b6d5607f 90.

According to the embodiment of the invention, after all the block chain nodes in the block chain network agree on the intelligent contract requested to be deployed, the intelligent contract requested to be deployed can be sent to the issuing end, the issuing end signs the intelligent contract requested to be deployed, and then the block chain nodes receive the intelligent contract requested to be deployed after signing from the issuing end. Therefore, the intelligent contract needs to be verified by multiple tags to be finally effective. Therefore, multiple parties determine the intelligent contract together, and the fairness, the justness and the transparency of the product can be ensured.

According to the embodiment of the present invention, it should be noted that only a specific blockchain account may be added with a plurality of blockchain accounts corresponding to a game developer, and the plurality of blockchain accounts may be at least the blockchain accounts signed by a blockchain network and the game developer.

Fig. 4 schematically shows a flowchart for generating a new blockchain account number according to an embodiment of the present invention.

As shown in fig. 4, generating a new blockchain account number includes operations S410 to S430.

In operation S410, an account generation request sent based on a blockchain account of an issuing end is obtained, where the account generation request is used to request generation of a new blockchain account, where the new blockchain account belongs to a newly added development end.

According to the embodiment of the invention, when a new development end needs to issue a new game through an issuing end, a new blockchain account can be generated based on the blockchain account request of the issuing end. The block chain account number of the issuing end has administrator authority and can control the addition of the issuing end.

In operation S420, a new blockchain account is generated in response to the account generation request.

In operation S430, a new blockchain account number is transmitted to the issuer.

According to the embodiment of the present invention, for example, the issuing platform block chain account number of the issuing end is: 0x9942e0dca0604579598e1c3b1cc338983ba8221e, game a assigned blockchain account number of the newly added game developer "airline" at the development end: 0x0042e0dca0604579598e1c3b1cc338983ba8221 c. According to embodiments of the invention, while generating a new blockchain account, a unique ID for game a may also be generated, such as 0x7642e0dca0604579598e1c3b1cc338983ba8221 d.

Fig. 5 schematically shows a flow chart of a transaction processing method according to another embodiment of the invention.

As shown in FIG. 5, a user can purchase the equivalent cryptocurrency, which is a virtual currency issued by the project issuer, using the legal currency. The user can use the existing virtual currency to purchase a certain designated game or participate in crowd funding projects through an open entrance of an intelligent contract, a block chain address and a private key of the user are used for initiating a transaction, and during purchase, a non-homogeneous unique pass certificate of a unique ID of the game or the crowd funding projects and a ciphertext encrypted by the non-homogeneous unique pass certificate and the private key are acquired. The purchasing behavior generates a corresponding transaction record transaction on the blockchain, the transaction record transaction displays a unique transaction hash value, the hash value can be displayed to the user in a clear text at the client, for example, the client can be a blockchain browser, and the hash value can be used for user identity confirmation, project activation and the like.

According to the embodiment of the invention, the project development end or the project issuing end can generate a batch of non-homogeneous unique certificates which are enough to be sold for the issued project through an intelligent contract based on the blockchain nodes in the blockchain network, wherein the non-homogeneous unique certificates have the same attribute, and the same attribute can be the unique ID of the project belonging to a certain blockchain.

According to the embodiment of the disclosure, the blockchain node sends a transaction record to the client so that the client activates the target object based on the content in the transaction record, wherein the transaction record comprises a transaction hash value (namely, a transaction hash value) displayed in a plaintext manner, a non-homogeneous unique pass certificate corresponding to the unique identifier of the target object, and a ciphertext encrypted by the non-homogeneous unique pass certificate and a private key.

According to an embodiment of the present disclosure, activating, by the client, the target object based on the transaction hash value includes: and performing identity verification on the client based on a private key and a transaction hash value input by the user at the client, continuously encrypting the ciphertext through the private key input by the user at the client after the identity verification is passed, broadcasting the ciphertext to each blockchain node in the blockchain network so as to perform public key verification on each blockchain node in the blockchain network through a user public key in the transaction record and a public key corresponding to the target object, and allowing the client to activate the target object after the verification is passed.

According to the embodiment of the invention, for example, the user can use the unique characteristic of the transaction hash value to invoke a plug-in (such as a blockchain wallet) at the client by using the own blockchain account to initiate identity confirmation, and the identity is confirmed to be owned by the account by verifying the signature sign. After the identity is confirmed, the public key corresponding to the non-homogeneous unique pass certificate purchased in the transaction is used for carrying out public key encryption on the ciphertext of the unique pass certificate, so that the corresponding information is not completely exposed to the development end of all projects, and is broadcasted to all block chain nodes for consensus.

And the whole network of the blockchain network verifies the public key by using the public key of the transaction From and the game public key of the appointed transaction, and the client activation request is agreed after the verification is passed. In the process of determining whether the identity is owned by the account, if the device environment related information in the current inputInfo (namely, the hardware information corresponding to the user terminal device, such as the mac address) is found not to conform to the device information originally initiating the transaction, the current device cannot use the game, and the problem of one number for multiple purposes is solved.

According to the embodiment of the invention, for example, the user Tony carries out identity authorization verification according to the Transaction From user address corresponding to the Transaction A Hash and initiating the Transaction, after the identity authorization verification is passed, the game ID of the game and the ciphertext of the unique pass A1 are broadcasted to the whole network, the public key verification is carried out, and if the Transaction verification is passed, the downloaded game can be used through game activation.

In operation S620, after the settlement is completed, the balance of the digital asset belonging to at least two blockchain accounts is destroyed.

According to the embodiment of the invention, for example, if the issuing end and the developing end settle the assets according to the balance of the respective accounts, the part which is finished by settlement can be destroyed in a plurality of ways. For example, an off-site transaction may be initiated, corresponding to the act of destroying transaction data on a transaction chain.

According to the embodiment of the invention, the destruction of the balance of the digital asset by the multi-party signature mode can be realized by respectively signing the destruction behavior by the issuing end and the developing end after the assets are settled by the issuing end and the developing end. Only after the parties sign the destruction behavior can the destruction be truly implemented for the digital asset balance.

According to an embodiment of the present disclosure, a blockchain link point may obtain a download request for requesting to download a blockchain, where the blockchain includes transaction records of different users; and responding to the downloading request, and sending the block chain to the request terminal so that the request terminal can disclose the information in the block chain.

According to embodiments of the invention, the requesting end may be an issuing end or a developing end of the target object. And analyzing the activation transaction in the block by downloading all blocks of the block chain network, and storing the acquisition transaction of the activation code and the parameters and results for verifying the activation transaction in a database. The analysis block transaction can be carried out through the function of the first block chain, and all data can be disclosed through a browser UI (user interface) interface and the like.

For example, the public data includes blockchain information of related transactions of each user, such as a player address, an amount of the related transactions, a transaction type, a crowd funding party participation share after crowd funding and a subsequent crowd funding project income condition, and the like. According to the embodiment of the invention, the user identity can be verified before the browser is viewed, and the corresponding viewing permission is obtained through the block chain account of the user.

Fig. 7 schematically shows a flowchart for transmitting a block chain to a requester in response to a download request according to an embodiment of the present invention.

As shown in fig. 7, sending a block chain to a requester in response to a download request includes operations S710 to S730.

In operation S710, it is determined whether the requester has a download right in response to the download request.

In operation S720, in the case that the request end has the download authority, the transaction modes and the transaction information of different transaction records are analyzed from the blockchain, where the different transaction modes correspond to different disclosure authorities.

In operation S730, the transaction mode and the transaction information of the transaction record in the blockchain are sent to the request terminal, so that the request terminal discloses the transaction information under the corresponding disclosure authority according to the transaction mode of the transaction record.

According to the embodiment of the invention, the transaction data in the transaction record can have different public requirements in the crowd funding mode and the non-crowd funding mode, and the download permission of the request end is different in different modes. For example, crowd funding generally requires transparent sales shares and transaction party identification, while non-crowd funding generally requires transparent transaction party identification.

According to an embodiment of the present invention, the pattern may be distinguished by extra data information attached to a transaction record transaction, the extra data information being a series of 16-ary encoded numbers, such as: 0x84da01d 900000000000000000000000000000000000000000000000001341477, which is defined as a crowd funding mode by a prefix distinguishing mode, such as beginning with 0x84 d.

Taking the example that the request end sends a request through the blockchain browser, the blockchain browser can import the data on the blockchain into the database of the server where the blockchain is located, and under the alliance chain, the blockchain browser can directly display the relevant result to the user by analyzing the extra data information. Of course, the corresponding result can also be obtained by directly analyzing the block chain link points, and the result obtained by analyzing is fed back to the block chain browser through the network, and then displayed to the user.

According to the embodiment of the invention, for the crowd funding mode and the non-crowd funding mode, if the sales is carried out based on a platform, a set of browser environment for internal viewing can be set up independently, only relevant parties such as an issuing end or a developing end can view the browser environment, and meanwhile, transaction records and balance information of respective accounts on a block chain can be directly viewed through commands. All sales are completely disclosed for specific authorized users, no one can steal tampering, and the information is transparent.
