Detailed Description
The alliance chain is a block chain. A block chain (Blockchain) is a distributed book, and is a technical scheme for collectively maintaining a reliable database in a decentralized and trust-removing mode. From a data perspective, a blockchain is a distributed database that is nearly impossible to alter. The "distributed" here is embodied not only as distributed storage of data but also as distributed recording of data; from a technical point of view, blockchains are not a single technique, but are the result of an integration of multiple techniques. The federation chain of the invention is aimed at the members of a certain group and limited third parties, and participates in network activities through the verification of public keys and private keys, the participant who joins the federation chain is called a node, and the node has the special functions of the federation chain after joining two parties, such as decentralized storage, encrypted storage and the like. The invention provides a secondarily developed interface Rest API for users in a alliance chain.
The super ledger is an open source project which is the main project of the Linux foundation and aims to promote the block chain to be applied across industries, belongs to a alliance chain type, and Fabric is one of five parallel projects below the super ledger. Fabric is a licensed blockchain architecture that provides a modular architecture that services nodes in the architecture, execution of intelligent contracts (chain code), and configurable consensus and membership. A Fabric network includes interfaces for peer nodes to execute intelligent contracts, access ledger data, endorse transactions, and be referred to as applications. The commander node is responsible for ensuring the consistency of the block chain and conveying endorsed transactions to the peers in the network; and an msp (memberships serviceprovider) service, which is mainly used as a certificate authority to manage the x.509 certificate, so as to verify the membership and the role, provide the functions of identity examination and the like.
The smart contracts (smartcontracts), also known as chain codes (chaincodes) in Fabric, are a set of numerically defined commitments (promises) that include protocols on which contract participants can execute such commitments. In blockchain, an intelligent contract is just some specific code running on a blockchain network of computers (or other nodes), and once a node executes the code, the contract updates the transaction information.
The channel is a private block chain constructed on the Fabric network, and realizes the isolation and confidentiality of data; the channel-specific ledger is shared with all peers in the channel, and the transacting party must pass the correct validation of the channel to interact with the ledger. Channels may also exist in the basic service layer described in the present invention, which are used to implement isolation of each service space data.
The embodiment provides a chemical data storage and sharing method and platform based on a alliance chain technology.
In one aspect, the present embodiment provides a chemical data storage and sharing platform based on federation chain technology. Referring to fig. 1, the platform includes a three-layer network structure of a base layer (Grand Space), a base service layer (Function Space), and a Customized service layer (Customized Space). Wherein the Grand Space is managed as the basis of all other spatial networks. The Function Space comprises a node Storage resource providing service management subspace (Storage Space), a value content exchange subspace (Token Space), a node network resource management subspace (order Space) and a public Compound Space (Compound Space), wherein the Storage Space provides Storage mechanism management, the Token Space provides a transaction voucher mechanism, the order Space provides transaction record sequencing management, and the Compound Space provides public resources and services. The Customized Space provides a platform for establishing a private Space for a user, and participants of any blockchain can create the private Space at the layer and customize personalized services in the private Space based on an intelligent contract.
Specifically, a global Ledger Grand Ledger work based on global operations is created in the base layer (Grand Space). The basic layer (Grand Space) is the basis of other spaces (spaces), and the account book is used for recording the registration of all other spaces, configuration information change and the like. The base layer (Grand Space) ensures the stability of the alliance chain network. And a transmission network, a chain structure, a password mechanism, a time stamp, a secret mode, a verification mechanism, a shared information platform and the like are established on a foundation layer (Grand Space).
Further, the transport network provides P2P network support for each communication Node (Node) in the blockchain network, which is one of the basic services for guaranteeing the consistency of the blockchain account book.
The transmission network comprises three types of communication nodes, namely a complete function node, a peer node and a storage function node.
The complete functions comprise sorting (order), endorsement and auditing and data knowledge storage.
The peer node is a data endorsement node, completes data endorsement of the block chain transaction record and achieves the function of decentralization.
And the data storage node refers to complete information related to knowledge in the transaction information, and in order to ensure high availability of the blockchain network, the platform stores the information in a key-value form. The key is stored in a decentralized mode, namely the point needing endorsement, and the value is the complete information pointed by the stored key. All keys are stored on a node with peer function in the form of ledger transaction records for decentralized data storage, each key points to a value, and the values store special single data storage nodes.
Further, the chain structure is used to determine a complete chain of transactions, e.g., the blockchain system creates a block at intervals, where the block contains all transactions that occur on the network-wide basis during the interval. Data is permanently recorded on a block chain through block packaging, each block is composed of a block head and a block body, and the hash value of a parent block referred by the block head of each block is recorded in the block head of each block.
Further, the cryptographic mechanism is a one-way cryptographic mechanism that the blockchain guarantees that the transaction information is not tampered, and the verification function may be one of an encryption algorithm (ECC, SM2/4), a hash algorithm (SM3, SHA256), and a signature algorithm (ECDSA, SM 2).
Further, a timestamp is typically a sequence of characters that uniquely identifies a time of a moment. By means of a cryptographic mechanism and a time stamp it is possible to record what has happened at a certain time and to avoid tampering with the data.
Further, the security method is a key security method, and in this embodiment, two keys are required: a private key and a public key. The public key and the private key are a pair, and if data is encrypted by the public key, the data can be decrypted only by the corresponding private key.
Further, a verification mechanism is used to verify the correctness of the encryption algorithm. In this embodiment, a Merkle tree is used for comparison and verification.
Further, the shared information platform is used for displaying information specified in intelligent contracts such as keywords, abstracts and the like of messages issued by users in the private space.
Public Function spaces (spaces) such as a value content exchange Space (Token Space), a node Storage resource providing service management Space (Storage Space), a node network resource management Space (order Space), a public Compound Space (Compound Space) and the like are set up on a basic service layer (Function Space).
Further, a value content exchange Space (Token Space) specifies four external functions of account transfer, value conversion, reward and bonus for the nodes to use. The node can transfer the value by calling a transfer function. Token Space observes a record of a specified Space contract. Thereby realizing the value conversion into the value of the value content exchange space contract. Because different spaces may be involved in transactions, the generated transaction voucher needs to be recorded, and the recorded content needs to be stored in Token Space according to the specification. Therefore, no matter the private Space or the public Space needs to store data to Token Space, the platform makes a public gateway according to the mode to manage the interaction (transaction certificate record, query) between Token Space and other spaces.
Further, the value content exchange space is accompanied by two ancillary functions, bonus and bonus, as shown in fig. 3. For the reward, for example, a user in the Compound Space uploads a standard Compound message, and the audit is passed according to the Compound Space rule, then the user is rewarded according to the rule, and transaction records are generated to generate transaction credentials, and the transaction records are recorded in Token Space. For red separation, there are two ways: the method I is that the TokenSpace is set to carry out bonus sharing on users holding the Token according to the end of a certain period, which is equivalent to the same reason of bonus sharing, and the purpose is to encourage the users to acquire more Token. In the second mode, the user provides the function of ordering in Orderer Space, and the rule of giving one time of reddening according to a deadline is also adopted.
Further, the book (leader) in Token Space is dedicated to record the reward and bonus rules of other spaces (including other business spaces of function Space and user-defined private spaces)
Further, an Ledger (Ledger) in the value content exchange space provides transaction logging functionality for nodes in the custom business layer.
Further, all the service nodes of the network need to participate in the Token Space network for endorsement.
Furthermore, users in a node Storage resource providing service management Space (Storage Space) design intelligent contracts of node management, the content of the intelligent contracts comprises functions of judging node joining and quitting, calculating node online time, storing data volume statistics, node role switching and the like, each node or organization joining the Space must fulfill the function of the intelligent contract, and after the intelligent contracts are executed, resources contributed by the nodes or the organizations obtain rewards through Token Space.
Furthermore, a node network resource management Space (Orderer Space) provides an operation Space for a user who is willing to join the network to become a sequencing node, an intelligent contract corresponding to the Space is used for calculating the resource consumption condition of user sequencing, and interaction is realized with Token Space, that is, data change needs to be recorded in Token Space. All users joining the federation chain are approved (authenticated by public and private keys), no preemptive data endorsement exists, and in order to improve transaction speed, the federation chain needs to send endorsement data to a sequencing node (Orderer node) with a sequencing function (Orderer) first, and then to sequence and distribute the endorsement data to a node (peer) needing endorsement through the Orderer node. The transaction amount of the whole alliance chain is completed by sequencing nodes in a node network resource management Space, the data amount is very large, in order to maintain the stability and reliability of the network transaction speed, an order function is opened to all nodes added into the alliance chain, the nodes providing the order function are recorded in Token Space, and then the nodes are divided according to the service providing time limit.
Further, the Compound data of approved compounds is stored in the public Compound Space (Compound Space). Specifically, a user operation node submits an application for registering a Compound (Compound) into a public Compound space; the method comprises two modes of manual auditing and automatic instrument auditing of public compound space setting: adding an audited participant in the manual audit; and the machine audit sets a general audit flow. Because some compounds have a fixed format, a universal audit rule can be set in an intelligent contract in Compound Space, but the universal audit rule of some compounds cannot be audited, and manual participation is needed. If the audit is not passed, the audit is submitted again; and if the audit is passed, registering the compound into a public compound space, and applying the function of the TokenSpace to provide rewards for the applicant and the auditor.
All network participants can join in the Customized service layer to establish their own private Space (channel), and make their own services through intelligent contracts, and the Customized service layer can refer to the Function of the Function Space of the basic service layer (Function Space). The custom Space is independent from the Function Space, and has no dependency relationship, and the participants of the blockchain network may not depend on the Function Space at all when creating the private Space, but must record in the Grand Space. However, most of the Customized Space needs to rely on functions in Function Space, such as Token Space for value exchange credentials, and Storage Space for data query.
Further, the value content exchange Space will interact with Space in the form of a gateway. For example, in connection with FIG. 5, the interaction of the public compound space with the value content exchange space: the public compound Space will provide the user with the relevant functions in its own Space, and when the Space has the relevant operations related to the Token function (e.g. data uplink reward of the compound), will interact with the value content exchange Space through the gateway, recording the operations of this public compound Space in the value content exchange Space. The subscribed service layer (Customized Space) is also implemented by the gateway if it is desired to use the service Space and the transaction credentials need to use Token Space. Taking the example of the customized Space calling the public compound Space function, when the function in the public compound Space needs to be called, some Token (Token) needs to be paid to obtain the related rights and interests, and the operation is activated through the gateway mechanism of the value content exchange Space and recorded in the book of the value content exchange Space. The purpose of the mode is to implant the excitation and red separation mechanism of Token Space into each Space in a plug-in mode to improve the vitality of the service Space.
The account book management scheme in the platform is as follows: and dividing the specific Space into a service Space and a basic Space according to the service mode. After the block chain network architecture based on the alliance chain is completed, the Grand Space and the token Space are firstly constructed to be used as the base Space. Secondly, the architecture service Space comprises Compound Space, Storage Space, OrderSpace and the like for providing service. And providing a functional interface of the customized Space on the basis for the user to deploy the user-defined Space. When the node is added into the platform, different functions can be achieved according to different machine performances, including that the fully functional node has all functions, the auditing function peer is only used for auditing functional Space services such as compound authenticity and endorsement auditing operation contents, and the storage function node has a data storage function. Users must join the platform network in a CA authenticated manner before using the platform functionality. The specific implementation is shown in figure 2.
The data storage and sharing mechanism of the common compound space (compound space) in the platform is as follows: the method comprises the following steps of constructing a Compound Space, establishing a set rule, adding a service node related to the Compound service, submitting an application for entering the Compound register into the Space by a user operation node through the Space, and setting a manual review mode and an automatic review mode by an instrument by the Space: and adding the audited participants in the manual audit, and auditing and setting a general audit flow by a machine. And if the audit does not pass, re-submitting the audit. And if the audit is passed, registering the compound into the Space, and applying the function of Token Space to provide rewards for the applicant and the auditor. Specifically, as shown in fig. 4, a participant submits a compound application, and a general audit rule is set for an intelligent contract with a fixed format in a compound space for audit, but some compound general audit rules cannot be audited and need to be audited manually, and the manual audit is participated by an audit information participant.
The transaction voucher management Space in the platform is used as a gateway to unify the interaction mode with other business spaces, the purpose of the mode is to implant the excitation and red separating mechanism of Token Space into each Space in a plug-in mode to improve the vitality of the business Space, and the method specifically comprises the following steps: the Token Space interacts with other service spaces in the form of a gateway, and fig. 5 shows an interaction mode of a compound Space (compound Space) and the Token Space. The service Space will provide the relevant function for the user in its own Space, when the Space has relevant Operation related to the Token function), for example, the data uplink reward of the compound will interact with the Token Space through the Token Operation Box, and the Operation of the service Space is recorded in the Token Space. Other customized spaces are also realized through the gateway if the business Space is used, and the transaction certificate is required to use Token Space. Taking the customized Space calling the Compound Space function as an example, when a function in the Compound Space needs to be called, some Token may need to be paid to obtain the relevant rights and interests, and this operation will be activated through the gateway mechanism of the Token Space and recorded in the account book of the Token Space.
On the other hand, the embodiment also provides a method for implementing chemical data storage and sharing based on the above platform, which includes:
step 2, building the infrastructure of the block chain network by means of a series of functions such as identity management, public and private keys, a center-removing storage mechanism and the like which are specific to the alliance chain technology;
step 3, constructing a basic layer (Grand Space), and creating an account book Grand edge based on global operation;
step 4, constructing a basic service layer (Function Space) comprising public Function spaces such as Token Space, order Space, Storage Space and Compound Space;
and 5, constructing a Customized service layer (Customized Space), and making own services by network participants through intelligent contracts and sharing data.
Further, in step 3, the participants of the network join the base layer (Grand Space) as the main Node (Grand Node) through identity management. Nodes (nodes or peers) and users (users) joining the network need to register in the base layer (Grand Space), and the base layer (Grand Space) manages information content uniformly and stores the information content in a decentralized manner.
The nodes are physical nodes such as computers and servers, and the users refer to people. Because the blockchain network is constructed by a plurality of nodes, a user needs to pass through a certain node to use the functions of the network. Before using the network, the user needs to register in the Grand Space to inform. The Grand Space will store this user information decentralized.
Further, in step 4, the Function of the basic service layer (Function Space) provides basic functions and incentive and bonus mechanism for the private Space of the user, including basic transaction record storage and credential Function, transaction record ordering Function, data storage Function, public resource and service, and reward and bonus mechanism.
In step 5, the data sharing includes that the data side shares data, and the data demand side acquires data. The data sharing method for sharing data by the data sharing party comprises the following steps:
a1, the local server of the data sharing party accesses the block chain network of the platform;
step A2, the data sharing party establishes private space in the customized business layer in the local server and generates public account book;
step A3, the data sharing party uploads the sharable data to the private space and encrypts the sharable data;
step A4, the data sharing party makes an intelligent contract in the private space;
step A5, the data sharing party publishes brief information of sharable data on the common platform of the platform base layer.
The data acquisition method for the data demander comprises the following steps:
step B1, the data demand party obtains brief information on the public platform of the platform block chain network;
step B2, the data demand side sends an application to the data sharing side to join the private space;
step B3, the local server of the data sharing party judges whether the data demand party is allowed to join the private space according to the intelligent contract;
step B4, the data demand party joining the private space refers to the intelligent contract to buy the sharable data from the data sharing party;
and step B5, the data sharing party sends the sharable data to the data requiring party.
Further, the public ledger described in step a2 records all operations of each node in the private space except for viewing the public ledger, including the node of the data sharing party and the node of the data requiring party. The public account book is a distributed account book, and data in the public account book can be shared, copied and synchronized among all nodes in the private space; each node maintains the public ledger at a corresponding local server, i.e. backups local information related to the transaction into the public ledger. The distributed account book with the block chain adopted by the public account book has the advantage that one node cannot privately change data in the public account book unless all nodes in the private space agree to change the data in the public account book.
Further, the encryption is performed in step a3 by using the bcccsp encryption algorithm.
Further, in step A4, the smart contract contains all information about the transaction, and the transaction that conforms to the smart contract is irreversible and traceable.
Further, the brief information described in step a5 may be presented in the form of keywords or summaries on a common platform of the platform blockchain network. The private space has its own intelligent contract in which various rules are formulated in which it is shown which information in the private space can be exposed on the public platform of the platform blockchain network and queried by others.
Further, in step B3, the data demander owns the public key after joining the base layer, and provides the private key to the data demander when the private space agrees to enter the private space. One public key corresponds to one private key, and when the public key and the private key pass verification, the private space can be accessed.
Further, in step B5, the shared data is directly transmitted from the data sharing party to the data requiring party by means of P2P, without passing through a third party platform.
Furthermore, when the data demand side uses the shared data, if there is difficulty or problem, it can directly communicate with the data sharing side by means of P2P.
The system borrows a alliance chain technology, a multi-account system is connected into a designed system, and a multi-account architecture system which takes a global space as a basis and a personal private space as branches and leaves is constructed.
According to the design, the network is provided with a system space for the participants to use after being started, the participants can create a space with customized services on the basis of the system space, for example, a company creates a private space based on public compounds on the basis of a bottom layer, and an intelligent contract corresponding to the space is designed for a specific flow of compound uploading. When a user builds a customized contract, the customized contract will be associated with the base space.
