In the invention, the existing Fileoin excavation cluster adopts the architecture shown in FIG. 1 and is divided into a mine pool server (also called mine pool server) and an ore machine server cluster. The mining pool server runs a daemon process of the Filecin, data of the whole block of the Filecin need to be synchronized, receives data uploaded by a client or a local, stores the data into the belt packaging sector, and then sequentially distributes the sector data to the mining pool server to be executed. Because the read-write operation of the data is realized by the communication between the ore machine server and the ore pool server, when the ore pool server has the problem of writing, other ore machines cannot write the data into the ore pool server due to the existence of the mutual exclusion lock, and the mutual exclusion lock is a simpler mechanism for realizing the mutually exclusive access of the threads to the resources. Because the time and space overhead of operating the mutual exclusion lock are low, the mutual exclusion lock is more suitable for key shared data and program segments which are frequently used, the mutual exclusion lock can have two states, namely an unlocking state and a locking state, because the mine pool server is in the locking state at the moment, the work efficiency of waiting for unlocking is slow, and simultaneously, because the internal storage capacity of the mining machine can not meet the large-capacity storage space required by calculation increasingly, the expansion is limited.
Referring to fig. 2 and 3, the present invention provides a method for parallel mining by multiple mining machines based on a block chain shared storage technology, wherein the method comprises the following steps:

S22, modifying codes of ore excavation software distribution tasks on the ore pool server, carrying out task segmentation numbering, and compiling a write-in executable file; and carrying out sectional design on a distribution task, wherein the distribution task is that the ore machine servers run a sector number, and each ore machine server runs different numbers to achieve the purpose of concurrence. In the specific implementation process, the sector numbers only need to be written into the corresponding configuration files, when the mining machine servers run the sector numbers of the current section, only the corresponding configuration files need to be modified, and the sector number distributor is utilized to avoid mining operation of the mining machine servers by using the same sector numbers.

The disk storage space is usually mounted on a designated server in a client mode, and the capacity of a PB-level virtual disk is provided, so that the storage capacity of each storage cluster can reach 100TB, horizontal expansion is supported, and the maximum capacity supports hundreds of PB storage spaces. In other words, in the present invention, the storage server software maps the storage space of the disk array of the storage cluster to the storage client software, and the storage client software is installed on the mine pool server and each of the mine servers, so that a storage space capable of being shared is formed.
S103, the mining machine cluster creates a shared folder in the storage space, and data and mining machine configuration are shared through the shared folder, so that mining can be conducted in parallel through the same miner address.
The mining pool server in the mining cluster creates three shared folders in a storage space, wherein the shared folders comprise a cache data folder, a tape package data folder and a chain loading data folder. In this way, all the ore servers and pool servers can share data and ore configurations, cooperatively mine with the same miner address, and have the algorithm displayed as an ore node on the block browser.
Further, when the mine pool server is started, three folders of cache, unsaled and sealed are generated. The cache caches data to be chained, unsealed stores data to be packaged, and sealed stores data which are stored and finished in a chain. When the sector is calculated each time, the data file is written into the unsealed data file, then the data file is pushed to the mining machine server, the mining machine server starts to copy the proof evidence, after the proof-of-copy evidence is calculated, the proof is transmitted back to the mine pool server, finally the mine pool server calculates the space-time proof, and links the proof-of-copy and the space-time proof. After finishing, packaging the data of the next sector; the program in the ore server also needs to run a filejoin process, receive data transmitted by the ore pool server in real time and calculate the copy proof evidence of the sector.

Compared with the related art, the multi-ore-machine parallel ore digging method and equipment based on the block chain shared storage technology have the following beneficial effects:
1. the IO bottleneck of disk reading and writing is solved by adopting a distributed shared storage mode, when each mining machine reads and writes a shared disk generated by the skink cloud, data are striped and stored to the server of each storage server cluster in a concurrent mode, and the same server is not read and written any more. Therefore, the more the number of the storage clusters is, the faster the read-write disk speed of the mining cluster is, and the disk IO of a single server is broken through. In concrete implementation, a plurality of mining machines write data into the distributed storage cluster through the skyline cloud client, in order to avoid read-write collision, a lock mode is usually adopted to ensure the uniqueness of the data, and therefore data safety concurrent read-write is achieved. The whole process is no longer a way of reading and writing the disk by a single mineral machine, and the concurrent way greatly promotes the disk IO.
2. The concurrency capability of the mining machine cluster is improved, and the mining machine configuration is shared, so that all the mining machines can access the same mining machine configuration, and the mining is performed on the Fileoin network by using the same miner address, and the parallelization degree of mining is greatly improved.
3. Providing a flexible configurable storage capacity for the mining machine. By adopting the space chain cloud trusted distributed storage software, the disk can be mounted on a specified mining machine in a cloud disk mode through the space chain cloud client, the capacity of the disk can be dynamically configured, the space of the disk is not limited in machine hardware, and the cost is greatly saved.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
