Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

First, the nouns involved in the embodiments of the present application will be described:

blockchain (Blockchain): is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and the like. The blockchain is essentially a decentralised database, which is a series of data blocks generated by cryptographic methods, each data block containing a batch of information of network transactions for verifying the validity (anti-counterfeiting) of the information and generating the next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.

The blockchain underlying platform may include processing modules for user management, basic services, smart contracts, operation monitoring, and the like. The user management module is responsible for identity information management of all blockchain participants, including maintenance of public and private key generation (account management), key management, maintenance of corresponding relation between the real identity of the user and the blockchain address (authority management) and the like, and under the condition of authorization, supervision and audit of transaction conditions of certain real identities, and provision of rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node devices, is used for verifying the validity of a service request, recording the service request on a storage after the effective request is identified, for a new service request, the basic service firstly analyzes interface adaptation and authenticates the interface adaptation, encrypts service information (identification management) through an identification algorithm, and transmits the encrypted service information to a shared account book (network communication) in a complete and consistent manner, and records and stores the service information; the intelligent contract module is responsible for registering and issuing contracts, triggering contracts and executing contracts, a developer can define contract logic through a certain programming language, issue the contract logic to a blockchain (contract registering), invoke keys or other event triggering execution according to the logic of contract clauses to complete the contract logic, and simultaneously provide a function of registering contract upgrading; the operation monitoring module is mainly responsible for deployment in the product release process, modification of configuration, contract setting, cloud adaptation and visual output of real-time states in product operation, for example: alarms, monitoring network conditions, monitoring node device health status, etc.

The platform product service layer provides basic capabilities and implementation frameworks of typical applications, and developers can complete the blockchain implementation of business logic based on the basic capabilities and the characteristics of the superposition business. The application service layer provides the application service based on the block chain scheme to the business participants for use.

Blockchains can be divided into private chains, alliance chains, and public chains; the federated chain is also referred to as a community blockchain (Consortium Block chains), which refers to a blockchain whose consensus process is controlled by preselected nodes. In a federated chain, all or part of the functions are only opened for node members within the chain, and each blockchain node in the federated chain can customize read-write permissions, query permissions, etc. based on needs.

Consensus mechanism (Consensus mechanism): is a mathematical algorithm for realizing trust establishment and rights acquisition among different nodes in a block chain system. In a blockchain system, the verification and confirmation of a transaction can be completed in a short time through voting of special nodes, and if a plurality of nodes with irrelevant interests can reach consensus for one transaction, all the nodes in the system can be considered to reach consensus for the same.

Intelligent contract: the method is characterized in that the method refers to a contract program which is automatically executed according to specific conditions, and is an important way for a user to interact with a blockchain and realize business logic by utilizing the blockchain. The basic idea of the intelligent contracts is that various contract terms can be embedded into the hardware and software used by us, so that an attacker needs great cost to attack, the intelligent contracts are diffused and stored in a blockchain by the common participation of multiparty users in customizing and utilizing a Peer-to-Peer (P2P) network, and the intelligent combination of the blockchain construction is automatically executed under the triggering condition. For example, each organization may access the data storage system through smart contracts on a blockchain deployed in a server to use the data storage and data querying functions provided by the data storage system. Smart contracts are essentially a set of conventions that are defined, propagated, verified, or executed in digital form, including that contract participants can execute conventions in smart contracts, which also allow trusted transactions to be made without third parties, and which transactions are traceable and irreversible. For example, the method for generating the prize exchanging result provided by the application is executed according to the prize exchanging intelligent contract, whether the prize exchanging code held by the player is consistent with the winning code is determined according to the prize exchanging intelligent contract, and when the prize exchanging code is consistent with the winning code, the player is determined to win the prize.

The system according to the embodiment of the present application may be a distributed system formed by connecting a client and a plurality of nodes (any form of computing device in an access network, such as a server and a user terminal) through a network communication.

Taking a distributed system as an example of a blockchain system, referring to fig. 1, fig. 1 is a schematic structural diagram of a distributed system 100 applied to the blockchain system according to an exemplary embodiment of the present application, the distributed system is formed by a plurality of nodes (arbitrary computing devices in an access network, such as servers and user terminals) and clients, a peer-to-peer (P2P) network is formed between the nodes, and a P2P protocol is an application layer protocol running on top of a transmission control protocol (TCP, transmission Control Protocol) protocol. In a distributed system, any machine, such as a server, a terminal, may join to become a node, including a hardware layer, an intermediate layer, an operating system layer, and an application layer.

Referring to the functionality of each node in the blockchain system shown in fig. 1, the functions involved include:

1) The routing, the node has basic functions for supporting communication between nodes.

Besides the routing function, the node can also have the following functions:

2) The application is used for being deployed in a block chain to realize specific service according to actual service requirements, recording data related to the realization function to form recorded data, carrying a digital signature in the recorded data to represent the source of task data, sending the recorded data to other nodes in the block chain system, and adding the recorded data into a temporary block when the source and the integrity of the recorded data are verified by the other nodes.

For example, the services implemented by the application include:

2.1 Wallet for providing electronic money transaction functions including initiating transactions, i.e., sending a transaction record of the current transaction to other nodes in the blockchain system, and after verification by the other nodes, storing record data of the transaction in a temporary block of the blockchain in response to acknowledging that the transaction is valid; the wallet also supports the inquiry of electronic money remaining in the electronic money address. For example, the information of the stimulus object to be added is sent to the blockchain system, other nodes in the blockchain system verify the transaction (namely, the information of the stimulus object is added in the blockchain), and after the other nodes verify successfully, the transaction can be stored in the blockchain.

2.2 The shared account book is used for providing the functions of storing, inquiring, modifying and the like of account data, sending record data of the operation on the account data to other nodes in the blockchain system, and after the other nodes verify to be effective, storing the record data into a temporary block as a response for acknowledging that the account data is effective, and also sending confirmation to the node initiating the operation.

2.3 A computerized agreement that can execute the terms of a contract, implemented by code deployed on a shared ledger for execution when certain conditions are met, for completing automated transactions based on actual business demand codes, such as querying the physical distribution status of the goods purchased by the buyer, transferring the electronic money of the buyer to the merchant's address after the buyer signs for the goods; of course, the smart contract is not limited to executing the contract for the transaction, and may execute a contract that processes the received information. For example, when a specific condition is met, the incentive object triggers the smart contract to execute an incentive mechanism according to the rule of the contract, such as issuing corresponding benefits or reddening to the incentive object.

3) The blockchain comprises a series of blocks (blocks) which are connected with each other according to the generated sequence time, the new blocks are not removed once being added into the blockchain, and record data submitted by nodes in the blockchain system are recorded in the blocks. The blockchain in the present application is a redemption blockchain, for example, in the redemption process, the redemption code data for each lottery object is recorded in the blockchain.

Referring to fig. 2, fig. 2 is a schematic diagram of a Block Structure according to an exemplary embodiment of the present application, in which each Block includes a hash value of a transaction record stored in the Block (hash value of the Block) and a hash value of a previous Block, and the blocks are connected by the hash values to form a Block chain. In addition, the block may include information such as a time stamp at the time of block generation. The blockchain is essentially a decentralised database, and is a series of data blocks which are generated by association using a cryptography method, and each data block contains relevant information for verifying the validity (anti-counterfeiting) of the information and generating the next block.

Fig. 3 illustrates a block chain system architecture diagram according to an exemplary embodiment of the present application. The system comprises a plurality of servers 101 and a plurality of storage devices 102, wherein the plurality of servers 101 can be configured with the same blockchain, i.e. the plurality of servers 101 can form a blockchain system, and each server 101 is a node in the blockchain system. Optionally, the nodes in the blockchain system include a master billing node and other nodes, any of which may become a master billing node. The plurality of servers 101 may be a plurality of servers of the same institution or a plurality of servers belonging to different institutions, for example, a server of each department of a hospital may be included in the blockchain system; the blockchain system may include servers of various departments of the company, although servers of securities exchanges, banks, etc. may also be included in the blockchain system. The user of each organization may access the servers of the organization through a terminal 1011, and the plurality of terminal devices 1011 may be electronic devices capable of accessing the plurality of servers 101, which may be computers, smartphones, tablets, or other electronic devices.

Of course, in order to perform services such as security verification and rights management, a CA center (Certificate Authority ) 103 is configured in the blockchain system, and is used to store keys of respective institutions, and respective servers in the blockchain system may obtain keys of respective institutions, such as public keys of any node, from the CA center to perform processes such as encryption and decryption of data. The plurality of storage devices 102 are used to provide storage services for the plurality of servers 101, and it should be noted that the plurality of storage devices 102 may constitute a distributed storage system for providing storage data in a distributed manner.
