Description
Technical Field
The invention relates to the technical field of block chains, in particular to a block chain multi-chain hierarchical collaboration technical system.
Background
Multiple Atomic Chain (MAC for short) is a third type of ecological system at the bottom of a blockchain developed outside bitcoin and etherhouse, and is dedicated to the business application boundary and the technical boundary of expanding blockchain technology, so that a public user can really feel the value of blockchain technology, and the blockchain is not stagnated at an academic theory level but is more directly applied to the practice of development and application, and the development of the Multiple Atomic Chain is a spark of collision between the business application and the blockchain technology and a challenge to the prior art of the blockchain, and the thinking in the prior art is jumped out, and the blockchain is a blockchain 3. 0 pioneer of the ecological application system. In the multi-primitive chain system, point-to-point value transfer can be realized through a value transmission protocol, and the characteristics of high performance, high throughput and rapidness and safety are the characteristics of the multi-primitive chain, so that a decentralized scene application development ecological platform supporting multiple industry fields (finance, Internet of things, supply chain, social contact, game, e-commerce, tracing, transaction and the like) is constructed by using the bottom layer of the multi-primitive chain.
In a public chain of multi-primitive chains (in the public blockchain system, anyone can read all over the world, anyone can send a transaction and the transaction can be validated, a blockchain in which anyone can participate in the consensus process (the consensus process decides which block can be added to the blockchain and makes explicit the current state), as an alternative to centralized or quasi-centralized trust, the security of the public blockchain is by "encrypted digital economy" in the form of a workload attestation mechanism or a rights attestation mechanism, combining economic rewards and encrypted digital authentication, and following the general principle that economic rewards available from everyone are directly proportional to the contribution made to the consensus process.
The discrete conversion is continuously confirmed by voting of a traditional discrete consensus algorithm, the continuous random sampling is upgraded, only one part of all nodes is selected to obtain a result, and the repeated sampling is carried out for multiple times, so that the full coverage is realized. When the result of the random sampling converges to a confidence value, consensus is achieved. The running efficiency of the asynchronous system is improved in a parallel consensus mode, and the concurrency performance of the system is further improved by matching with a multi-node design of the asynchronous system. The method does not need to be connected with most nodes in the consensus process, votes are obtained, system data transmission is saved, the dependence of the nodes on a network body is reduced, the nodes are randomly selected, a random calculable function is used, a user can know whether the nodes are selected or not according to calculation, and the result is fed back and broadcasted to other users.
Among the three phases experienced by the traffic data uplink, the consensus phase requires the participation of other blockchain nodes in the blockchain network. Research shows that when the service data is subjected to consensus processing, as the number of the block link points participating in consensus increases, the time for performing consensus processing on the service data is prolonged, and further the efficiency of the consensus processing on the service data is low.

Preferably, the establishing a master-slave multi-chain model of the block chain, the constructing of the master chain and the slave chain adopts different consensus mechanisms, and the time threshold is used as a delay boundary to constrain the cooperation process of each consensus mechanism, and the block chain is divided into an upper block chain and a lower block chain, and specifically includes:
the upper layer block chain comprises a base layer and a topology layer, and the base layer encapsulates the bottom layer data block ^ type and the related technologies of data encryption, time stamping and the like; the topology layer comprises a distributed networking mechanism, a data transmission mechanism, a data verification mechanism and the like; the subordinate layer block chain comprises a consensus layer and an application layer, wherein the consensus layer mainly encapsulates various consensus algorithms of the network nodes; the application layer integrates economic factors into a block chain technical system and mainly comprises an issuing mechanism, an allocation mechanism and the like of economic application, wherein the contract layer mainly encapsulates various scripts, algorithms and intelligent contracts and is the basis of the programmable characteristic of the block chain, and the application layer encapsulates various application scenes and cases of the block chain.
Organizing the whole block chain system through a hierarchical structure, indexing the block chain of a topological layer by a base layer block chain of an upper layer block chain to realize layering and customization of different functions, constructing verification nodes, constructing a main chain verification block by using a POW algorithm competition of the set when each group of verification node set is constructed, and adding the verification block into the main chain when the verification is passed after the construction is completed; the common recognition layer and the application layer of the lower layer block chain can realize different processing realization logics to realize different functions, so that the coupling degree of the system is reduced, and meanwhile, more diversified service customization is realized. And then screening a next round of verification node set, and constructing a next verification block. Of course, a malicious node that may exist in the network may construct an illegal verification block, and then the block cannot be verified, the round of consensus is not valid, and the height of the verification block is not changed.
Since the nodes indexed from the upper link to the lower link cannot be guaranteed to be stable (fail or exit), an indexing mechanism must be designed to ensure that the system has sufficient robustness, and the seed nodes recorded by the top link can be correctly indexed to the lower link. After the verification node set is screened out, the subsequent operations of block verification, branching pruning and the like are the same as the POW. The provided verification node set is dynamically constructed, so that the main chain consensus process is always dynamically changed, and the method has stronger safety and reliability. The client does not need to know the distribution organization structure of the chain and the load condition of the chain nodes, and needs to locate the server corresponding to the provided data through the index of the multi-level block chain, so that the whole indexing process is required to be completely transparent to the user. The time complexity of the algorithm used to construct the verification network is such that the time overhead incurred is negligible
Furthermore, one end of the control unit centralized control interface is connected with a group of input/output control pins of the microprocessor, and the other end of the control unit centralized control interface is interconnected with the centralized control interface application DB-9 interfaces of the switching devices with various network topological structures, so that the function of receiving/sending the switching instructions of the centralized network topological structures of the devices is realized.
The method is characterized in that an asynchronous sorting technology is originally created, and common knowledge is converted into the problem of processing large-scale concurrent requests of an asynchronous system and sorting data. The method is superior to the overall connectivity of the network, and can normally operate in the environment of a non-fully connected network even in a system with the network connection ratio of less than 50%. Meanwhile, a hidden layer network is used to approximate any continuous function by matching with a multi-hidden layer network. The framework replaces a single hidden layer by a deep network, and the result can be converged and normalized more quickly in the fitting process. The crowding is judged to reach the balance, the data value is shared and decided, numerous decision individuals form a conducting structure to simulate Neuron neurons, and the resultant force decision is made. The method comprises the steps of back propagation algorithm, multilayer partition and fog algorithm, network topology structure switching between weak centralization and decentralized centralization, and the mode of combining super nodes and supervision nodes, so that an asynchronous communication strategy is free from obstacles.
The Block chain is a single chain consisting of Block blocks and can only be synchronously and sequentially written according to Block time as if the single-core single-thread CPU is available; the DAG is a network formed by transaction units and can asynchronously and concurrently write in transactions as if the multi-core multi-thread CPU;
preferably, the topology structure comprises a core topology network (11) and a slave topology network (22), the core topology network (11) comprises a core master station 1 and a plurality of core slave stations 1 to n +1, and the slave topology network (22) comprises a slave master station 2 and a plurality of slave stations n +2 to 2n + 2;
the core master station 1 and one slave station 2n +2 serve as two core topology nodes and are communicated with each other through a system internal bus to form a core system, the core master station 1 serves as a master station of a core topology network (11), and the slave station 2n +2 serves as a slave station of a slave topology network (22);
the slave master station 2 and one of the core slave stations n +1 are used as two slave topology nodes and are communicated with each other through a system internal bus to form a slave system, the slave master station 2 is used as a master station of a slave topology network (22), and the core slave station n +1 is used as a slave station of a core topology network (11);
each controlled device is provided with at least one core slave station and slave stations at the same time;
a heartbeat count is arranged between a core master station 1 in the core system and a core slave station n +1 in the slave system and is used for monitoring whether a communication line of a core topology network (11) is normal;
and a heartbeat count is set between the slave master station 2 in the slave system and the slave station 2n +2 in the core system to monitor whether the communication line of the slave topology network (22) is normal.
When the account book data stored by the node is incomplete and the transaction content cannot be checked, data retrieval service needs to be requested from other nodes. Since there may be byzantine nodes in the network, make internal disorder or usurp is needed to ensure correctness of data retrieval service. The Merkel root hash value of the MPT-Chain digital asset state tree is stored in the block head of the micro-block, other nodes in the network reconstruct the MPT-Chain by using the transaction set in the block along with the broadcasting of the block to the whole network, the construction of the Merkel tree has uniqueness and irreversibility, and the characteristics can ensure the consistency of the whole network of the MPT-Chain. After the retrieval result is obtained, the data service request service node sends transaction information needing to be verified, other nodes return Merkel proofs after receiving the information, and the data service request service node recalculates Merkel root hash values by using the Merkel proofs received from the nodes and compares the Merkel root hash values to verify the accuracy of the data service.
Preferably, the electrically erasable programmable memory of the switching unit stores media access control and other state parameters, and the two-wire serial bus is connected with the network switching chip to realize information query of looking up device identification by the computer through the network interface of the switching unit.
Asynchronous communication strategy in the parallel processing technology, the information communication between tasks usually adopts 2 strategies, namely an asynchronous communication strategy and a synchronous communication strategy, thereby leading out an asynchronous parallel algorithm and a synchronous parallel algorithm. The synchronous parallel algorithm is a plurality of tasks in the execution process, a certain task is in a waiting state at a certain section and can not be activated until another task finishes a certain section of operation, the phenomenon does not exist in the asynchronous parallel algorithm, the communication among the tasks is carried out through global variables (shared data), the synchronous parallel algorithm does not have the dependency relationship among the tasks, the input among the tasks does not need to be waited, the tasks can be continuously executed and the data can be continuously obtained according to the information obtained from the global variables at present, and therefore the asynchronous algorithm has the advantage of avoiding the synchronous communication overhead among the tasks, and improving the speed-up ratio. However, the blockchain environment only supports a synchronous communication mechanism, the 2 node processes (tasks) connected with the same channel can only communicate when being respectively in an input/output ready state, otherwise the processes (tasks) already in the ready state (whether the input process or the output process) are always in a waiting communication state.
Furthermore, the consensus is converted by adopting an asynchronous sequencing technology, the asynchronous sequencing technology is originally created, the consensus is converted into the consensus for processing large-scale concurrent requests of an asynchronous system and the data sequencing problem, the overall connectivity of the network is superior to that of the network, and the network can normally operate even in a system with the network connection ratio of less than 50% in the environment of a non-fully-connected network;
multiple hidden layer networks, one hidden layer network is used to approach any continuous function, a deep layer network replaces a single hidden layer, and the convergence and normalization result can be faster in the fitting process
A back propagation algorithm, a multi-layer partition, a fog algorithm, a mode of switching network topology structure between weak centralization and decentralized centralization, and a mode of combining a super node and a supervision node.
Preferably, the dial switch group of the control unit is connected with a group of input/output control pins of the microprocessor, and a control signal is input; a Transputer-oeEAM environment realizes RungeKuttata asynchronous parallel algorithm, realizes debugging, updating and programming operation of a flash memory unit program in a microprocessor chip through an integrated development platform (IDE) of a computer operating system, integrates a plurality of functional blocks such as a CPU, a memory, a high-speed interconnection communication link and the like, and is provided with 4 pairs of bidirectional communication links which are used for linking processors to form a multiprocessor system with various topological structures.
Based on a master-slave multi-chain model of Hash anchoring, a plurality of slave chains are constructed to enable different types of digital assets to be processed in a classified mode, and slave chain blocks are constructed in parallel, so that transaction throughput is improved.
