It should be noted that the above application scenarios are only presented to facilitate understanding of the spirit and principle of the present invention, and the embodiments of the present invention are not limited in this respect. 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 side of the target object and a blockchain account number of an initiating side 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, a user Tony purchases game A via a client and downloads the game A, 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 unique to his own 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 intelligent contracts for games:
the game publisher distributes proportional playfacecent; game developers distribute proportion gamePercent; game developer blockchain address identity gameSignAddress;
uint signResult＝publish(platPercent，gamePercent，gameSignAddress)；
and obtaining respective related information according to the sign result, wherein the sign result can also comprise a unique ID of the gameId game, a playardress game issuer account address, a playuplic game issuer public key, a playrivate game issuer private key, a gameAdress game developer account address, a gamePublic game developer public key and a gamePrivate game issuer private key. 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 private key of the user blockchain must be kept by the user. 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 a 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 block chain address may be 2fb7fd4eb832bbb06ca3d04201d4c06a243aea eec8214dbbe7626b6d5607f90.
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.

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 after the identity verification is passed, the ciphertext is continuously encrypted through the private key input by the user at the client and is broadcast to each blockchain node in the blockchain network, so that each blockchain node in the blockchain network can carry out public key verification through the user public key in the transaction record and the public key corresponding to the target object, and the client is allowed 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 of the original initiated transaction, the current device cannot use the game, and the problem of one number with 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-through A1 are broadcasted to the whole network to carry out public key verification, and if the Transaction verification is passed, the downloaded game can be used through game activation.
