The execution main body of the embodiment is a blockchain client, a mobile phone, a tablet, a computer, a server, and the like, and can also be applied to a data processing system or a business system such as a service background, a service middle desk, and the like.
In this embodiment, before monitoring the account status of all nodes on the blockchain, the method further includes: setting a node machine on the block chain through an intelligent contract, and establishing a communication link between the node machine and each full node; and synchronously storing the key information of each full node locally in the node machine, wherein the key information carries the hash value of the full node.
Selecting all nodes in a block chain, assigning node machines to all nodes through intelligent combination, and synchronizing keys of all nodes (the keys store hash values and are used for identifying the blocks and tracing the blocks through the whole chain); and establishing a communication link between the node machine and the whole node for realizing information interaction between the node machine and the whole node.
The block chain can generate keys without limitation, each block chain is generated to represent one user node, so that the node machine can be used as a non-centralized system, and a writing netty service (providing an asynchronous and event-driven network application program framework and tools for rapidly developing a high-performance and high-reliability network server and a client program) is built on the node machine, so that the whole nodes on the block chain are controlled on the basis of the node machine through the client. The node machine of the embodiment is a server of one block in a block chain, different from a traditional block node, the block has one more web server service, tasks are mainly sent to other nodes and are also called special capacity blocks, the traditional block is a single recording block written into the block, the node machine of the embodiment records the block and then distributes the tasks to a certain client to generate data, and then the data are combined to start accounting processing and are restored.
In this embodiment, the performing authentication on the first full node includes:
s11, locally reading a first hash value of the first full node, and obtaining a second hash value of the first full node according to the first hash value, wherein the second hash value is stored on the client of the first full node;
in this embodiment, the first hash value is identification information of the first full node, and is a unique identity of the first full node on the blockchain, and the blockchain is obtained by performing hash algorithm conversion on the historical accounting task when the first full node is generated. The hash value of the block chain can uniquely and accurately identify one block, any node in the block chain obtains the hash value of the block through specific hash calculation, and the fact that the calculated hash value is not changed means that information in the block chain is not tampered, and identity authentication is passed.
In an implementation manner of this embodiment, obtaining the second hash value of the first full node according to the first hash value includes: determining the block identifier of the block to which the first hash value belongs; reading a second hash value stored on the client side by the block in the memory of the first full node by taking the block identifier as an index; and if the reading fails, continuously reading the third hash value of the second full node, and obtaining the second hash value of the first full node through third hash calculation, wherein the second full node is an adjacent block node of the first full node.
S12, comparing whether the first hash value is consistent with the second hash value;
s13, if the first hash value is consistent with the second hash value, the identity authentication is determined to pass; and if the first hash value is inconsistent with the second hash value, determining that the identity authentication is not passed.
The node machine can verify the authenticity of the user as a centralized service, a non-centralized system can ensure that data of the client cannot be tampered, and the block head information of the client is directly checked for the Hash value of the block head of the block to identify whether the node is abnormal or not in an index mode. The process comprises the following steps: extracting a first hash value in the secret key, determining a block identifier of a block to which the first hash value belongs, searching a second hash value stored on a full node of the block in a first full node by taking the block identifier as an index, reading the second hash value stored on the full node of the first full node, comparing whether the first hash value is consistent with the second hash value, if so, passing the identity authentication, and if not, failing the identity authentication.
In some scenarios, if the reading may fail (due to authority, malicious interception, and the like), the third hash value of the neighboring block (the last block or the next block on the blockchain) of the first full node on the blockchain is read, and the hash value of the first full node is obtained through hash calculation.
The blocks on the block chain are divided into block heads and blocks, each block head is related to a plurality of transaction transactions in the block by storing the hash value of the previous block head, each block is a so-called account book as long as the block head hash values (which are equivalent to the identity card number of one block) are connected in series, and all the nodes need to do is to keep the consistency of the own account book and other nodes.
The netty service is built on the node machine, the node machine obtains a secret key carrying a hash value based on the netty service, namely the web service, and the secret key is used as a token on the node machine and verifies the identity of all nodes by using the hash value in the secret key.
In one example of this embodiment, broadcasting accounting tasks to light nodes on the blockchain includes: splitting the accounting task into a plurality of subtasks; broadcasting the plurality of subtasks to all light nodes on the blockchain such that all light nodes compete for accounting rights of the plurality of subtasks based on a POW (Proof of Work) algorithm.
Optionally, the step of synchronously storing the feedback data of the light node as the accounting data of the accounting task to all the full nodes on the block chain includes: receiving M sub-hashes respectively fed back by M light nodes based on a plurality of sub-tasks, wherein the accounting task comprises a plurality of sub-tasks, and M is a positive integer greater than 1; and splicing the M sub-hashes to obtain accounting data of the accounting task, and synchronously storing the accounting data to all full nodes on the block chain.
In the splicing process, multiple modes can be adopted for splicing, each subtask is unique, so that the M sub hashes are also unique, a unique total hash can be obtained regardless of the splicing mode, and the splicing of the M sub hashes can be but is not limited to: splicing the M sub-hashes in sequence based on the feedback time of the M sub-hashes; and splicing M sub-hashes based on the task identifications of the multiple sub-tasks.
Fig. 3 is a block chain system architecture diagram according to an embodiment of the present invention, including: a plurality of full nodes (node 1, node 2, node 3), a node machine, a control client of the node machine, and a plurality of light nodes (node a, node b, node c). Broadcasting the accounting task to the light nodes, and receiving the accounting data fed back by the light nodes, wherein the light nodes can compete through a pow algorithm, and the node machine splices the accounting data (Hash + Hash) of each light node to obtain complete accounting data, and then synchronizes to other full nodes, including:
the light nodes compete through a POW algorithm, if the first light node is solved, a first subtask of the accounting task is extracted, and the first light node executes the first subtask to obtain a first sub hash; and until the Nth light node is solved, extracting the Nth subtask of the accounting task, executing the Nth subtask by the Nth light node to obtain the Nth sub-hash until the accounting task is distributed completely, splicing the sub-hashes (the first sub-hash + … + the Nth sub-hash) of the light nodes to obtain a complete hash value, and performing full-chain synchronization by using the complete hash value as accounting data.
In this embodiment, the accounting task may be divided into a plurality of subtasks, and each subtask corresponds to one light node. Or the dividing may be non-uniform, the dividing is performed according to a preset gradient, for example, the dividing is performed by one half, one third, one sixth, and the like, and the earlier the solution completion time is, the larger the distributed subtasks are.
The POW algorithm of this embodiment determines who to come out a block by calculating a difficulty value. The workload of the POW means that the equation is solved, and who solves the equation first and who has the right block. The equation calculates the hash value of the next block through the hash value of the previous block and the random value nonce, and who finds nonce first can calculate the hash value of the next block first, and this way is called as the calculation difficulty value because the equation has no fixed solution and can be tried continuously, and this way of solving the equation is called as hash collision, which is a probability event, and the more the number of collisions, the greater the difficulty of equation solution.
