Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "first" and "second" in this application are used for convenience of understanding only, and are not to be construed as sequential or limiting in any way.

For the purpose of facilitating understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.

Blockchains are generally divided into three types: public chain (Public Blockchain), private chain (PrivateBlockchain) and alliance chain (Consortium Blockchain). In addition, there are various types of combinations, such as private chain + federation chain, federation chain + public chain, and other different combinations. The most decentralized of these is the public chain. The public chain is represented by bitcoin and ether house, and the participators joining the public chain can read the data record on the chain, participate in transaction, compete for accounting right of new blocks, and the like.

Furthermore, each participant (i.e., node) is free to join and leave the network and perform related operations. Private chains are the opposite, with the network's write rights controlled by an organization or organization and the data read rights specified by the organization. Briefly, a private chain can be a weakly centralized system with strictly limited and few participating nodes. This type of blockchain is more suitable for use within a particular establishment.

Based on the basic characteristics of a blockchain, a blockchain is usually composed of several blocks. The time stamps corresponding to the creation time of the block are recorded in the blocks respectively, and all the blocks form a time-ordered data chain according to the time stamps recorded in the blocks strictly.

The real data generated by the physical world can be constructed into a standard transaction (transaction) format supported by a block chain, then is issued to the block chain, is identified by node equipment in the block chain, and is packed into a block by the node equipment serving as an accounting node in the block chain after the identification is achieved, and is subjected to persistent evidence storage in the block chain.

In the field of blockchain, an important concept is Account (Account); taking an ether house as an example, the ether house generally divides an account into an external account and a contract account; the external account is an account directly controlled by the user; and the contract account is created by the user through an external account, the account containing the contract code (i.e. the smart contract).

Of course, for some blockchain items derived based on the ethernet framework, the account types supported by the blockchain may be further expanded, and are not particularly limited in this specification.

For accounts in a blockchain, the account status of the account is usually maintained through a structure. When a transaction in a block is executed, the status of the account associated with the transaction in the block chain is also typically changed.

Taking etherhouses as an example, the structure of an account usually includes fields such as Balance, Nonce, Code, and storage. Wherein:

a Balance field for maintaining the current account Balance of the account;

a Nonce field for the number of transactions for the account; the counter is used for guaranteeing that each transaction can be processed only once, and replay attack is effectively avoided.

A code field for maintaining a contract code for the account; in practical applications, only the hash value of the contract code is typically maintained in the code field; thus, the code field is also commonly referred to as a codehash field. For external accounts, this field is null.

storage field to maintain the storage of the account (default to empty). In practical application, the storage field only maintains the root node of an MPT (Merkle Patricia Trie) tree constructed based on the storage content of the account; thus, the storage field is also commonly referred to as the storageRoot field.

Wherein, for the external account, the code field and storage field shown above are null values.

Most blockchain items typically use Merkle trees; alternatively, the data is stored and maintained based on the data structure of the Merkle tree. Taking etherhouses as an example, the etherhouses use MPT tree (a Merkle tree variation) as a data organization form for organizing and managing important data such as account status, transaction information, and the like.

The Etherhouse designs three MPT trees, namely an MPT state tree, an MPT transaction tree and an MPT receipt tree, aiming at data needing to be stored and maintained in a block chain.

The MPT state tree is an MPT tree organized by account state data (state) of all accounts in the block chain; the MPT transaction tree is transaction data (transaction) in a block and is organized into the MPT tree; the MPT receipt tree is an MPT tree organized by transaction receipts (receipts) corresponding to each transaction generated after the transaction in the block is completed. The hash values of the root nodes of the MPT state tree, MPT transaction tree, and MPT receipt tree shown above are all added to the block header.

Wherein the MPT transaction tree and the MPT receipt tree correspond to tiles, each tile having its own MPT transaction tree and MPT receipt tree. The MPT state tree is a global MPT tree, which does not correspond to a specific tile, but covers account state data of all accounts in the tile chain.

Based on this, the present specification will not specifically explain the hierarchical storage of the MPT transaction tree and the MPT receipt tree, but rather the hierarchical storage of the MPT status tree.

The above is a description of a storage structure in a conventional block chain, and the following is a description of a storage structure of a service data block chain in the present application.

The present specification discloses a point exchange method for a service data block chain, as shown in fig. 1, the implementation method is applied to a service data block chain system, and the service data block chain system includes a plurality of block chain nodes; the method includes S101-S102.

The entity information in the present specification refers to abstraction of objective objects and also refers to specific objective objects, the entity information includes associated attributes and non-associated attributes, and the associated attributes refer to that attribute values can be increased or decreased; the user information refers to description information of a user, and the user information comprises a user address; the point information is point information issued by the user, and is point information other than the original points on the block chain, and the point information includes the name and the total amount of the point.

S101, creating the first integral by the block chain node in response to the first integral creating operation of the first user.

And S102, responding to the setting of the exchange ratio of the first point and the second point of the first user, and setting the initial exchange ratio of the first point and the second point so as to facilitate the initial exchange of the first point and the second point.

In one example, the method further comprises: the block chain node determines the exchange proportion of the first point and the second point according to a preset rule, wherein the preset rule is set by the first user;

the preset rules comprise stock centralized bidding rules.

In one example, the method further comprises: the block chain node responds to a redemption request of a second user, the redemption request is used for redeeming a first number of first points into second points, and the redemption request is used for requesting redemption with the first user;

In one example, the method further comprises: the blockchain node receives a conversion transaction sent by a second user, wherein the conversion transaction comprises a signature of the second user, a first conversion proportion of the first point and the second point, a third number of first points and a fourth number of second points;

In one example, the method further comprises: the blockchain node receives a redemption request of a second user, wherein the redemption request comprises an address of the second user for locking a fifth number of first points, a second redemption proportion of the first points to the second points, a sixth number of second points and a signature of the second user on the locked address; wherein the blockchain node stores the redemption request through a state tree of entity information;

In one example, a relationship tree stores a redemption ratio of the first points to the second points; the leaf node value in the relational tree stores the exchange proportion of the first point and the second point in an array or hash table mode; or

In one example, the exchange proportion of the first points and the second points is stored in the database supporting attribute query in the form of a data table, so that a user can query according to attribute fields in the data table; wherein, any row in the data table corresponds to a state; the database supporting attribute query comprises a relational database and a memory database; or

In the above, a lot of service data, that is, operation data of the user, is stored in the service data block chain. The user operation data is operation data of a user on the Internet, and the user operation data comprises one or more of evidence storage data, tracing data, financial data, tourism data, search data, self-media data, research data, advertisement data, e-commerce data, community data, knowledge question and answer data, knowledge payment data, shared bicycle data, recruitment data, life service data, renting data, voting data, online-offline data, social data, approval data, evaluation data and vehicle appointment data.

For example, the entity is a commodity of an internet e-commerce platform, and the user can initiate an operation of purchasing the commodity, namely, an operation of transferring the points corresponding to the commodity entity (namely, the points are transferred from the address of the operating user to the address of the operated user); the user can also initiate a comment or a praise operation for the commodity, namely a user operation for the commodity entity.

In one example, the state data stored by the on-chain state database comprises points, and the attribute types of the point data comprise associated attributes and non-associated attributes; and the attribute value of the associated attribute is automatically increased or decreased according to the user operation data.

In this case, the point is a point issued by the user, for example: after a user can pass the notarization and securitize the house, a point is issued on the block chain, and the point uniquely represents the house property on the block chain; alternatively, the house may be securitized, a predetermined number of points issued, possession of the point will have ownership of the house, and will have equal ownership of the house lease or change. In addition, the block chain is provided with native scores which can be used for restricting the operation of the user on the block chain, so that the user is prevented from using the resources of the block chain system without limit; for example: after the users on the blockchain are registered, the users are operated on the blockchain, and the native credits are required to be collated so as to uplink the user operation data.

In one example, the association stored in the on-chain association database includes an association of entity information and user information; wherein, one entity information corresponds to one or more user information.

For example: on an electronic commerce platform (such as Taobao, Tianmao and Jingdong shopping mall) of the Internet, a commodity is purchased by a plurality of different users; on a self-media platform (such as WeChat and microblog) on the Internet, one piece of self-media data is praised or commented by a plurality of users; the one-to-many relationship between such entities and users can be expressed by using the association relationship between the entity information and the user information. The method and the device facilitate chaining of the service data and query of the service data by the user.

In one example, the association stored in the on-chain association coefficient database includes an association of user information and point information; wherein one user information corresponds to one or more point information.

At this time, a user may have multiple points; for example: a user has both native credits on the blockchain and other types of credits. The incidence relation can describe the one-to-many relation between the user and the score, and meanwhile, the user can conveniently inquire. It should be noted that a user in the blockchain system at least has the native scores of the blockchain system; it is possible to have credits issued by other users or by themselves.

In one example, the association stored in the on-chain association coefficient database includes an association of entity information and point information; wherein one entity information corresponds to one or more integral information.

At this time, equivalently, on the block chain, the securitization of the entity is realized; for example: the ownership of a commodity corresponds to an integral, and the transfer of the integral corresponds to the transfer of the ownership of the commodity; the ownership of a set of houses corresponds to a predetermined number of points, the number of owned points corresponds to the ownership proportion of the houses, and namely, the houses are owned to sell or rent the prices in the same proportion.

As described above, any one of the user information (e.g., Account field), credit information (e.g., Asset field), entity information (e.g., Object field), entity information-user information (e.g., Object-Account field), user information-credit information (e.g., Account-Asset field), and entity information-credit information (e.g., Object-Asset field) may be implemented by using an MPT status tree, and the tree roots of various MPT status trees are stored in the block header. As shown in FIG. 2, the user Action of the tile store (e.g., the Action field), and the root of the MPT state tree of the Receipt information stored by the on-chain database (e.g., the Recept field) are also stored in the tile header.

It should be noted that the block in the blockchain system includes a block header and a block body, the block header stores summary information, and the block body stores transfer information (also called transaction information). In this specification, the user operation is stored in a block of the block, and a digest value (also referred to as a hash value) of the user operation is stored in a block header; the on-chain state database in this specification is also part of the storage of the blockchain system, and each blockchain node has the on-chain state database and the block to store the service data in this specification.

In one example, the on-chain database is a database supporting attribute query or a KV database, wherein the database supporting attribute query includes a relational database and an in-memory database.

In one example, the attribute types of the user information and/or the entity information include an associated attribute and a non-associated attribute; and the attribute value of the associated attribute is automatically increased or decreased according to the user operation data.

In one example, any one of the user information, the entity information, the point information, the entity information-user information, the user information-point information, and the entity information-point information is organized into an MPT state tree; the MPT state Tree is a merkel Tree Merkle variety of a Tree structure fused with a prefix Tree Trie, and the merkel Tree Merkle is a merkel Patricia Tree state Tree.

In one example, any one of the user information, the entity information, the point information, the user information-the point information, the entity information-the point information and the entity information-the user information is stored in the database supporting attribute query in the form of a data table, so that a user can query according to an attribute field in the data table; one kind of information corresponds to one data table, any line in any one data table corresponds to one piece of information, and one kind of information comprises a plurality of lines of information; the database supporting attribute query comprises a relational database and an in-memory database.

In one example, any one of the user information, the entity information, the point information, the user information-the point information, the entity information-the point information, and the entity information-the user information is stored in a KV database and stored in a key-value pair manner.

In one example, any one of the user information, the entity information, the point information, the entity information-user information, the user information-point information, and the entity information-point information is organized into an MPT state tree; wherein the root of any one of the MPT state trees is stored in the block header.

In one example, the value of a leaf node in the relationship tree stores one or more of user information-point information, entity information-point information, and entity information-user information in a hash table or array.

In one example, the value of a leaf node of the relationship tree is to store a tree root of a relationship sub-tree that stores one or more of user information-score information, entity information-score information, and entity information-user information, the relationship sub-tree being a merkel tree or an MPT tree.

In the above, the information is stored in the way of the MPT state tree, and the user can query through the address information; directly adopting a user address, a point address and an entity address message to inquire information aiming at user information, point information and entity information; and aiming at the entity information-user information, the user information-integral information and the entity information-integral information, respectively adopting an entity address, a user address and an entity address to carry out information inquiry.

In addition, the user address can be obtained by carrying out multiple times of hash operation according to the user public key; the point address or the entity address may be obtained by a user operation of creating a point or an entity, for example: and carrying out multiple times of hash operation on the user operation, and selecting characters with preset digits from the obtained hash value as integral addresses or entity addresses.

In one example, the on-chain database employs a database supporting attribute queries, wherein the on-chain database includes a relational database and an in-memory database. That is, any state information of user information, point information, entity information-user information, user information-point information, and entity information-point information is stored by using a database supporting attribute query, the relational database can be MySql, and the memory database can be MongoDB.

At this time, by using the database supporting attribute query, the user information, the point information, the entity information-user information, the user information-point information, and the entity information-point information can be queried by using corresponding attributes, and the query efficiency of attribute query is higher compared with the query by using an address on a block chain. Meanwhile, the MPT state tree root of the above information is stored in the chunk header, as shown in fig. 2. In actual use, if any of the MPT state trees is not used, the MPT state tree can be set to empty.

In the specification, any one of user information, point information, entity information-user information, user information-point information and entity information-point information is organized into a data structure of an MPT state tree, namely a data logic structure, the adopted storage structure can be a KV database, such as L evalDB database, and also can be a MySql and MongoDB database which support attribute query, and the databases are physical storage structures.

The present specification enables the business data to be uplink, and enables various association relationships of the business data to be uplink; the benefits of the business data uplink include, but are not limited to, true trustworthiness, traceability, personal attribution of data rights, etc.

In addition, various attributes of the service data can be stored on the block chain by storing user operation data in the blocks and storing state data and state associated data in the on-chain state database, so that the problem of chaining the service data is solved; in addition, the state data and the state associated data stored in the state database on the chain are convenient for the user to access.

The specification also discloses a credit exchange device based on the service data block chain, wherein the service data block chain system comprises a plurality of block chain nodes, and the advertisement system comprises the block chain nodes and the first user equipment.
