One user may correspond to a plurality of terminal devices, which may be implemented in various forms. For example, the terminals described in the present invention may include mobile terminals such as cellular phones, tablet computers, notebook computers, palm computers, personal digital assistants, portable media players, and fixed terminals such as digital televisions, desktop computers, and the like. The following description will be given taking a fixed terminal as an example, and those skilled in the art will understand that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to an element particularly used for a moving purpose.
The terminal device may be a local device of the user, or may be other terminal devices that the user controls one terminal device to interact with through a network, specifically, the terminal device may be an application server, and the user interacts with an application program stored on the server online through a local client application program, for example, a web game used by the user through a browser, and the like.
The blockchain network includes a plurality of network node devices for performing blocksynchronization and consensus mechanisms, and includes a plurality of, e.g., common blockchains, including innumerable network node devices, for which any user may freely access and exit the blockchain network without authorization, and a blockchain, including a limited number of authorized network node devices, for which the user may access the blockchain network after obtaining authorization, depending on the architecture of the blockchain network and the programs running in the blockchain website, in embodiments of the present application, the blockchain network may be embodied as a blockchain, in other embodiments of the present application, as well as by other types of blockchain networks.
Specifically, as shown in fig. 1, in the present embodiment, the user a and the user B directly access the blockchain network through a local digital money wallet program to host one kind of homogeneous data of the digital money a to the blockchain network, the user B, the user C and the user F access the blockchain network through a network connection to an online digital money wallet program to host another kind of homogeneous data of the digital money B to the blockchain network, the user C, the user D, the user E connect to a game application server of a game provider through a local game client program, the game server connects to the blockchain network to host homogeneous data of game credits and heterogeneous data of game props to the blockchain network, the user E access to a game web server of the game provider through a browser, the web server connects to the blockchain network to host heterogeneous data of game roles to the blockchain network, the user F and the user G access to a third party platform server, and the third party platform server connects to the blockchain network to host the picture of the user in the platform, the heterogeneous link data of the animation to the hosting network.
Referring to fig. 2, which is a schematic flow chart of a digital asset management method according to a preferred embodiment of the present invention, it can be seen that the digital asset management method provided in the present embodiment mainly includes the following steps:
Step S201: digital asset information of a user is received, the digital asset information including a digital asset type and corresponding digital asset data.
Specifically, digital asset information of a user is received, where the digital asset information includes a digital asset type and corresponding digital asset data, the digital asset information includes information for identifying and classifying the digital asset of the user, that is, the digital asset information sent by the user, including the digital asset type and corresponding digital asset data, for example, the digital asset information sent by the user a includes a digital asset type, that is, the digital currency a, and a corresponding digital asset type, that is, an amount corresponding to the digital currency a. For example, by receiving digital asset information sent by user A, digital currency A200, to host user A's 200 digital currency A to the blockchain network.
Step S202: the digital asset information of the user is stored distributed to a blockchain network.
The digital asset information of the user is distributed and stored in the blockchain network, the digital asset information comprises digital asset types and corresponding digital asset data, then the digital asset types and the corresponding digital asset data are distributed and stored in the blockchain network through block synchronization, the block synchronization is an important function for providing the distributed and stored blockchain data, the distributed and decentralized storage is formed through the distributed and stored blockchain network through the block synchronization, and therefore the trust mechanism and the security are enhanced.
Step S203: and acquiring the transaction address of the transaction object after receiving the digital asset transaction instruction sent by the user.
When the user hosts the digital asset to the blockchain network, if the digital asset needs to be retrieved or transacted, a transaction instruction can be sent to the hosting platform, and after the hosting platform receives the digital asset transaction instruction sent by the user, the transaction address of the transaction object is obtained from the blockchain network.
When the transaction object is the user himself, namely when the user retrieves the own digital asset, the transaction address of the transaction object is the user himself, and when the transaction object is the other user, namely when the user and the other user transact the digital asset, the transaction address of the transaction object is the transaction address of the other user.
Step S204: and transferring a preset amount of the digital asset data to the transaction address after verifying that the digital asset type is a preset type.
Because multiple different types of digital assets for multiple users are stored on the hosting platform, for example, as shown in fig. 1, multiple types of digital assets for user a, user B, user C, user D, user E, user F, and user G are stored on the hosting platform, for example, user a and user B host digital asset a, user B, user C, and user F host digital asset B, user C, user D, and user E host game prop A1 of game a, user F hosts game character B1 of game B, user F, and user G host cartoon pictures of platform a, and when a digital asset transaction instruction sent by a user is received, it is necessary to determine the digital asset type first.
For example, because user B hosts digital currency A and digital currency B, when receiving a transaction instruction from user B to transfer digital currency A to address XXX for an amount of 100, it is necessary to determine that the digital asset type is digital currency A and to transfer 100 to transaction address XXX after confirmation. Digital money a is thus homogenous data, and only a portion of the digital asset data needs to be transferred if user B's digital asset data, i.e. the balance, is greater than 100.
In this embodiment, the digital asset includes a plurality of digital asset types having different tags and at least one digital asset data corresponding to each of the digital asset types.
For example, because user C hosts digital currency C and game a, receiving a transaction command sent by user C to transfer game a prop A1 data to address yyyy requires first determining that the digital asset type is game a prop A1, and then transferring game a prop A1 to transaction address yyyy after confirmation.
Because game a may include both homogeneous data, i.e., game credits, and non-homogeneous data, e.g., game props, where a game prop may include a plurality of different props having different identifications for distinguishing digital asset types, when the digital asset type is game credits, the digital asset type corresponds to one digital asset data, and when the digital asset type is game prop, the digital asset data corresponds to a plurality of digital asset data, each corresponding to a different parameter of the game prop.
Because a non-homogeneous digital asset, such as a prop, is unique, the digital asset data is different for different non-homogeneous digital assets, all of the digital asset data corresponding to the prop is transferred at the time of the transaction.
According to the digital asset management method provided by the embodiment of the invention, the digital asset information of the user is stored in the blockchain network in a distributed manner by receiving the digital asset information of the user, the transaction address of the transaction object is obtained after the digital asset transaction instruction sent by the user is received, and the preset amount of digital asset data is transferred to the transaction address after the digital asset type is verified to be the preset type, so that a digital asset unified management scheme is realized, the digital asset of the user is stored in the blockchain in a decentralised manner, and compared with the centralized storage scheme in the prior art, the situation that the digital asset is lost due to the fact that the data is modified by the centralized platform or the physical storage position of the centralized platform encounters a non-resistance factor is avoided, and therefore the safety of the digital asset of the user is improved.
As shown in fig. 3, step 202: the distributed storage of the digital assets into the blockchain network specifically comprises:
step S301: and generating a first blockchain network address corresponding to the user.
Because of the plurality of users, each user may host a plurality of different types of digital assets, in addition to marking the types of digital assets, user information needs to be marked, specifically, a first blockchain network address ZZZ corresponding to the user information is generated when the digital assets are stored in a blockchain network in a distributed mode, the address corresponds to different user accounts, and the first blockchain network address ZZZ corresponding to a certain user account can correspond to a plurality of different types of digital asset addresses XXX and yyyy.
Step S204: the transferring the predetermined amount of digital asset data to the transaction address after verifying that the digital asset type is the predetermined type further comprises:
step S302: and transferring a preset amount of digital asset data to the transaction address after the first blockchain network address meets a preset condition.
In this embodiment, in addition to verifying the type of the digital asset, it is also required to verify whether the user information of the transaction is correct, that is, the first blockchain network address meets the preset condition, because in this embodiment, a plurality of users are included, each user may host a plurality of different types of digital assets, so that in addition to verifying the type of the digital asset, it is also required to verify the user information, and when the user verification fails, no digital asset transfer is performed, so that the occurrence of the same type of digital asset transfer errors of different users can be prevented, and the security is further improved.
As shown in fig. 4, in this embodiment, further includes:
step S401: generating a key corresponding to the first blockchain network address and signing to generate signature information;
step S402: writing the signature information into the blockchain network;
step S302: the transferring the preset amount of digital asset data to the transaction address when the first blockchain network address meets a preset condition specifically includes:
step S403: and after judging that the first blockchain network address meets the preset condition according to the signature information in the blockchain network, transferring preset quantity of digital asset data to the transaction address.
The keys in the blockchain are divided into a public key and a private key, wherein the public key and the private key are a key pair obtained through an algorithm, namely a public key and a private key, the public key is a public part of the key pair, and the private key is a non-public part. The public key is typically used to encrypt a session key, verify a digital signature, or encrypt data that may be decrypted with a corresponding private key. The key pairs obtained by this algorithm can be guaranteed to be unique worldwide. When using this key pair, if a piece of data is encrypted with one of the keys, it must be decrypted with the other key. For example, encrypting data with a public key must be decrypted with a private key, and if encrypted with a private key must also be decrypted with a public key, otherwise decryption will not succeed.
Specifically, a private key is first generated using a random number generator. Typically this is a 256-bit number that is owned to operate on the corresponding digital asset in the user's first blockchain network address.
The private key is algorithmically processed to generate a public key. For example, by using elliptic curve algorithm, it is possible to obtain a public key by using a known private key, but the public key cannot be obtained by reverse calculation when the public key is known, so that the security can be improved.
In a distributed network of blockchains, nodes communicate and trust, and digital signatures are relied on, which involve public keys, private keys, and blockchain network addresses, to prove that a message is indeed signed and sent by an information sender.
In the embodiment, the key corresponding to the blockchain network address is signed to generate the signature information, and decryption and signature verification are carried out when the digital asset is transferred, so that the difficulty of user information verification and cracking can be improved, and the safety is further improved.
As shown in fig. 5, in this embodiment, the users include a first type of user and a second type of user, specifically, the first type of user is a personal user, the second type of user is a platform user, and the personal user may directly host the digital asset to the blockchain network, or may host the digital asset in the platform to the blockchain network through the platform in the identity of the platform user.
The digital asset data includes homogenous data, such as digital currency, or non-homogenous data, such as game play items, the method further comprising:
step S501: and receiving a login request of the second type user.
The platform needs to register with the hosting system as a user and possess corresponding user information.
Step S502: and generating the homogeneous data according to the third user input of the second type user through the first type user after the verification is passed, or generating the heterogeneous data according to the fourth user input of the first type user.
Because there are multiple individual users on the platform, after the platform is successfully logged in, the individual users input operations within the platform to form digital assets, such as generating digital currency, obtaining game props, and the like.
Specifically, an individual user logs into an asset hosting management platform, invokes an intelligent contract to generate a custom homogeneous or uses the intelligent contract to generate a custom heterogeneous digital asset. The second type of user, namely the platform user, accesses the asset hosting management platform, and publishes the digital assets of the first type of user to the hosting platform according to business requirements.
Step S202: after the digital asset information of the user is distributed and stored to the blockchain network, the method further comprises the steps of:
Step S503: and generating a second blockchain network address corresponding to the digital asset type.
Step S504: associating the second blockchain network address to the first type of user.
Each different type of digital asset, e.g., a different play object, of a user has a corresponding network address. After the digital asset is hosted, the asset hosting management platform stores the digital asset in a distributed manner into a blockchain for hosting and generates a record, each digital asset has a unique address, the generated asset is associated with a user account address, and a user can view the digital asset held by the user on the asset hosting management platform.
In this embodiment, the users include a first type of user and a second type of user, specifically, the first type of user is a personal user, the second type of user is a platform user, and the personal user may directly host the digital asset to the blockchain network, or may host the digital asset in the platform to the blockchain network through the platform in the identity of the platform user.
In another embodiment of the present application, only a first type of user, the digital asset data comprising either homogeneous data or heterogeneous data, the user does not need to go through a third party platform, but directly hosts his digital asset on the chain through a distributed application.
Wherein the method further comprises: and receiving a login request of the first type user, and generating the homogeneous data according to intelligent contract input called by the first user of the first type user after verification is passed, or generating the heterogeneous data according to intelligent contract called by the second user of the first type user.
In the embodiment, the unified hosting and storing of various different types of digital assets of different users in the blockchain is realized, the different types of digital assets do not need to be independently stored respectively, and the different users do not need to be stored respectively.
As shown in fig. 6, in this embodiment, the method further includes:
step S601: receiving a sharing request sent by the second type user;
step S602: responding to the sharing request to acquire digital asset data corresponding to the first type of user;
step S603: and after passing the verification, transferring the digital asset data corresponding to the first type of user to the second type of user.
Specifically, in the present embodiment, the setting belongs to specifying a certain game exclusive digital asset. The shared asset may be queried by a game server that is authorized to share the asset to obtain user-held data. For example, a player holds 10X props on a chain, and at the same time, game A is authorized to use the X props, then the server of game A can inquire about 10X held by the player through an interface provided on the chain and approve the use in the game, and only the only occupied party of the asset authorization can inquire the digital asset of the user and be related to the game server, so that the security in the process of transferring the digital asset is improved.
As shown in fig. 7, in this embodiment, the second type of user includes a plurality of users, and the method further includes:
step S701: receiving a sharing request sent by at least one second type user;
step S702: responding to the sharing request to acquire digital asset data corresponding to the first type of user;
step S703: and after passing the verification, transferring the digital asset data corresponding to the first type of user to the other second type of user.
Specifically, in this embodiment, with multiple platform users, digital assets of a first type of user in different platforms may be shared. For example, a setting belongs to a specified plurality of game shares. The shared digital asset may be queried by a game server authorized to share the asset to obtain user-held data. For example, a player hosts 10X props on a blockchain while game A and game B are authorized to use the X props, then game A's server and game B's server can query the player's 10X's through the interface provided on the chain and approve use within the game.
When the user hopes that the account number in the game is bound with the asset under the address in the blockchain, the information which comprises the game identifier, the player identifier in the game and is signed by using the private key of the address is required to be sent to the intelligent contract of the platform blockchain for binding, and the platform intelligent contract judges that the authorization of the address is valid and records the corresponding relation according to the signature information after receiving the information.
In this embodiment, the digital asset management scheme may enable a plurality of users to store a plurality of different types of digital assets, where the different types of digital assets may be distributed and processed by different digital asset distribution platforms, and by using the unified digital asset management scheme, when it is determined that the conditions are satisfied, the digital assets are transferred and traded between different platforms, thereby improving the liquidity of the digital assets.
According to the digital asset management method provided by the invention, the digital asset information of different types of users is stored in a distributed manner to the blockchain network by receiving the digital asset information of the different types of users, the trading address of a trading object is obtained after a digital asset trading instruction sent by the users is received, and a preset amount of digital asset data is transferred to the trading address after the digital asset types are verified to be of the preset types, so that a digital asset unified management scheme is realized, the digital assets of the users are stored in the blockchain in a decentralised manner, and compared with the centralized storage scheme in the prior art, the situation that the digital assets are lost due to the fact that the centralized platform modifies data or the physical storage position of the centralized platform is subjected to an unreliability factor is avoided, so that the security of the digital assets of the users is improved.
