Specifically, bitcoin is a decentralized network architecture, forwarding new transactions and new blocks through the nodes that install bitcoin daemons. The mining machine and the mine pool form another network at the same time, which is called a miner network.
The miners' network is divided into several major parts, including the ore machine, the mine pit, the purse, and the like, and sometimes the mine pit software is installed with the purse, which may be collectively referred to as the mine pit.
The communication protocol between the ore machine and the ore pool software is stratum, and the communication between the ore pool software and the wallet is a bitcoinrpc interface.
The stratum is JSON in a data format, and the specific protocol is as follows:
1. task subscription
The mine machine starts, and is firstly connected with a mine pool by a mining. The mine pool returns the subscription number, ExtraNonce1 and ExtraNonce2_ size with mining.
2. Task allocation
The command is sent periodically by the pit to the mining machine, which should return to the task as soon as the mining machine registers with the mining.
3. Ore machine login
The mining machine logs in the mine pit by using a certain account and a password by using a mining. The method must be performed immediately after initiating the connection, otherwise the mine machine is not given the mine pit mission.
4. Result submission
And when the mining machine finds legal share, submitting a task to the mining pool by a' mining. The mine pool returns true, i.e. the submission is successful, and if the mine pool fails, there is a specific reason in error.
5. Difficulty adjustment
Difficulty adjustment is carried out on an ore machine sent from an ore pond, the difficulty is adjusted by a mining set _ difference method, and the difficulty value in params is the difficulty value.
The mine machine will adopt the new difficulty in the next task, and the mine pool will sometimes immediately issue a new task and set the cleaning task to true so that the mine machine will immediately work with the new difficulty.
As shown in fig. 5, the server is connected to and communicates with each of the ore machines through a bus. Since the number of mine machines in a mine site is several hundreds to several thousands, the sequential failure detection of all the mine machines by engineers is unacceptable in terms of time. Therefore, the invention provides a fault detection method based on the network topology structure.
The Merck root of a file is first obtained from a trusted source, and once the root is obtained, the Merck tree can be obtained from other untrusted sources. The received Mercker tree is checked through the trusted root of the tree. If the Merck tree is corrupted or spurious, another Merck tree is obtained from another source until a Merck tree matching the root of the TrustedTree is obtained.
As shown in fig. 6, a method of detecting a failure of a mining machine according to still another embodiment of the present invention includes: step 602, sending a status query signal; step 604, whether all root consistent signals are received, if yes, step 606 is entered, and if no, step 608 is entered; step 606, waiting for the next status query; step 608, executing the state query algorithm; step 610, inquiring a fault machine, entering step 612 when the result is yes, and returning to step 608 when the result is no; and step 612, reporting the fault mining machine and waiting for the next state query.
Specifically, the server sends out identical status inquiry signals to all the mining machines (e.g., n mining machines) at certain intervals (preferably, one hour), and the mining machines send the mercker root value of the block head to the server after receiving the status inquiry signals. If the calculation state of the mining machine is normal, the Mercker root value of the block head sent by the mining machine is consistent with the Mercker root value stored in the server in advance; if the mining machine state is failure, the Mercker root value of the block head sent by the mining machine is inconsistent with the Mercker root value stored in the server in advance.
The transaction record is stored by using the transaction list, and in the past 10 minutes, all newly generated transaction lists in the whole network are stored in a new block, and all blocks are connected in series to form a block chain. The blockchain thus corresponds to a distributed book. Each node in the whole network participates in maintaining the account book together. A new block is generated every 10 minutes and is updated to all nodes in the entire network synchronously. After the confirmation of the whole network, the change can not be carried out.
After sending out the state query signal once, the server counts whether root value consistent signals (for example, n root value consistent signals) equal to the total number of the mining machines are received or not. If a consistent signal of root value equal to the total number of the mining machines is received, the server waits for the next state query. If no consistent signal of root value equal to the total number of the mining machines is received, the server executes a state query algorithm to detect which mining machine is out of order. When the fault mining machine is inquired, the server reports the number of the fault mining machine to the mining field and the mining pool, so that an engineer can conveniently maintain the mining field and the mining pool can redistribute the calculation task.
As shown in fig. 8, assuming that there are n ore machines in the mine site, the n ore machines can be divided into the two most closely numbered parts. For example, if n is an even number, the n is divided into two groups, each n/2; n is an odd number, one is (n +1)/2, and the other is n- (n + 1)/2.
When a fault is confirmed in n mining machines, the n mining machines are divided into two groups, and then the fault is randomly detected for one group (namely, the state query signal is sent again for the group of mining machines). If no faulty machine is detected (i.e. the state detection unit 10 receives signals equal to the number of tackers root values), the next group is detected, and if a faulty machine is detected (i.e. the state detection unit 10 does not receive signals equal to the number of tackers root values), it is reported. The method is iterated repeatedly, and the mining machine with the real calculation fault can be found.
The steps of the state query algorithm are summarized as follows:
step 802: halving the number of the ore machines or closest to halving;
step 804: carrying out state detection on one group of mining machines;
step 806: determining whether the fault mining machine is in the current group, if so, entering step 4, and if not, entering step 5;
step 808: a status check is made for another set of mining machines and then returns to step 802.
Step 810: and confirming whether the fault mining machine is detected, if so, entering a step 812, namely reporting the fault mining machine and finishing the inquiry process, and if not, then returning to the step 802.

As shown in fig. 7, a state detection unit is included in the server, which is composed of the following units: a control unit 704, a counting unit 702, and a sending and detecting signal unit 706. The specific arrangement is shown in the following figures:
at each status inquiry, the control unit 704 controls the sending and detecting signal unit 706 to send a status inquiry signal to each mining machine through the bus, and the sending and detecting signal unit 706 sends a signal including the mercker root value, which is fed back by each mining machine through the bus, to the counting unit 702. The number of mercker root values that coincide with the mercker root values stored in advance is counted by the counting unit 702, and the counted number is sent by the counting unit 702 to the control unit 704. The control unit 704 confirms whether the faulty mining machine is present in the current round of inquiry.
As shown in fig. 9, in the network topology, some ore machines are set as master ore machines, which play the role of the server in embodiment 1, that is, each master ore machine includes a status detection unit 10 therein, and each master ore machine executes the above-mentioned status query algorithm proposed by the present invention on its own ore machine cluster through a bus. When a fault mining machine is detected, the main mining machine reports the reporting server to a mining field and a mining pool. This network structure decomposes the query task to each host machine, thereby effectively reducing the amount of computation of the server and enabling a faster location of a faulty machine than in embodiment 1.
