mining pools: How do I extract BTC using normal home computers if I have several computers?

To put it clearly, anyone who needs to participate in the Bitcoin exchange record update, known as can do it as such. All you need is to calculate an irregular number that unravels a condition produced by the frame. It sounds direct, is not it?

Obviously, this speculation is made by your PC. The more dominant your PC is, the more theories you can do in a moment, expanding your chances of winning this game. In the case that you discover how to calculate correctly, you acquire bitcoins and have the opportunity to compose the "next page" of the Bitcoin exchanges in the block chain.

  1. When your mining PC makes the correct estimate, your mining project determines which of the current pending exchanges will meet. The assembly of this square speaks of its instantaneous brilliance, since it has now become an impermanent Bitcoin investor who has the opportunity to update the Bitcoin exchange register known as blockchain.

  2. The square you have made, along with your answer, is sent to the whole system so that different PCs can approve it. It is something like Rubik's 3D form: the arrangement is difficult to achieve, however it is extremely simple to approve.

  3. Each PC that approves your answer updates your duplicate Bitcoin exchange record with the exchanges you entered in the square.

  4. The framework produces a fixed measure of bitcoins (at this time 12.5) and rewards you as you pay for the time and vitality you spent solving the math problem.

  5. In addition, you are paid for the exchange expenses that were related to the exchanges that you inserted in the next box.

  6. Each of the exchanges in the box you have recently entered is currently confirmed by the Bitcoin organization and is basically irreversible.

RBITT is the bitcoin exchange company registered in the United Kingdom. RBITT is the most reliable, secure and easy way to carry out the transaction with credit card, PayPal, bank transaction and many more. You can easily buy from RBITT with a few clicks.

How do the mining pools connect to the Bitcoin network and the miners connect to the pool?

How do the mining pools connect to the Bitcoin network to propagate transactions and blocks?

They connect in the same way as all the others that connect to the Bitcoin network. The miners are still nodes, they do everything a complete node does.

Do they run their own complete node?


If so, how many full nodes?

At least one. It does not matter how many nodes a miner is running, as long as they are running a node. At least one node is needed so that they can see the transactions and the blocks and so they can issue their own blocks. Large mining operations can have multiple complete nodes. The little ones can only have one. It is difficult to know how many and which nodes belong to the miners, since they resemble any other node in the network.

How do miners connect to a pool? Is there a server executed by mining groups so that the miners can connect?

The mining groups operate servers that give work to the miners with that group. The miners have to connect to those servers to be able to work. They can be connected using a variety of protocols. The two protocols in use today are stratum and getblocktemplate.

Performance: how many thread pools are used to accelerate a Spring-based web application

I have a spring mvc web application. To improve performance, I decided to run 2 methods on 2 beans asynchronously. These 2 tasks are:

  1. Creating an image from a loaded pdf file and storing it on the server

  2. send mail

I have currently used a ThreadPoolTaskExecutor and it has improved performance. The minimum size of the grouping is equal to the no of the processors and the maximum size is a multiple of the minimum quantity. Is it a good idea to use 2 ThreadPoolTaskExecutor so that each subprocess group has similar tasks?

Mining pools: What is a relationship with the total hash rate (hash power) and the average block generation time?

This table: the hash rate means the total hash rate of All minor?

I think the most important factor for the difficulty and time of block generation is the hash rate of the largest mining pool No total hash rate of all minors.

I want to assure you that if there is a mining group it has 30% of the total hash rate and this mining group is the largest group.

Then, this mining group will be able to find objective hash value faster than others (stochastically).

Therefore, I believe that the difficulty for the block generation time will be established by this mining group.

As a result, if other mining groupings do not have a sufficient hash rate, for example, 10% of the total hash rate, and then stochastically, 3 more times are needed to find a trag value.

So I think the most significant factor is the hash rate of the largest mining group

Am I thinking right?

And it looks like it's out of title, but I have one more question.

If the bifurcation occurs, can the mining pool recognize that the fork has occurred?

mining pools: is block completion a valid development to eliminate the threat of 51% attacks?

If "block completion" is needed, then your chain is broken. I say this because PoW is the method by which the Bitcoin network maintains a consensus, so the only reason we can introduce a "block completion" is if we are concerned that PoW can not do its job. If PoW can not do its job, then the system is already broken. It really is quite simple.

Consider: if 51% attacks are occurring and the malicious miners are reorganizing the chain every few blocks, what good is the "block purpose"? The system is already apparently broken.

Add any type of & # 39; block completion & # 39; You can also introduce new problems and attacks:

Consider: if some nodes in the network somehow have a different history that goes back more than ten blocks, then the network Never Being able to reach a consensus without manual intervention.

Then, if a node is Sybil / eclipse attacked and fed with a false history by its peers, it will now be Never You can return to the longer valid string, since you will not follow a reorganization of more than 10 depth blocks. Given a network at risk of 51% attacks, why should we assume that this would not happen? Rewinding 10 blocks could be quite easy for an attacker with a majority of hash power, so the "block completion" means that the dangers associated with the Eclipse and Sybil attacks are much greater than before. Without block completion, a node only needs an honest pair at any time, but with block completion, a node needs an honest pair every ten blocks. A small but extremely Important distinction

In addition, there are even situations in which this could cause problems without the involvement of malicious actors. If any part of the backbone network infrastructure collapses and temporarily isolates a part of the nodes and miners, how will they synchronize with the larger network again? They could not, without manual intervention.

So the "purpose of the block" is not a technically sound idea. It is a band for a broken network.

Mining pools: Is the Bech32 transaction on accurate?

I made a transaction and I paid like 120 sat / B, in blockchain it says that I paid 78,995 sat / B and I noticed that the size of the transaction is 191 (bytes)

The transaction size is assumed to be: 102 (input) + 32 (output) + 10 (headers) = 144 Byte

Is this a problem and is the transaction fee correct or did the wallet not send the correct rates and the miners accept my transaction when I paid 120 sat / b or 78 sat / b?


mining pools – Startum protocol extranonce2 – where comes extraNonce2

Extranonce2 is generated by the miner who does the work. When a miner runs out of nonces in the block header, he can increase Extranonce2 in the coinbase transaction so that a much larger search space can be given for a valid PoW because of the difficulty in which they are being mined.

The grouping must provide the size of Extranonce2 because Extranonce2 is not a real field in the coinbase, but is part of the arbitrary data of variable length that a miner can include in the coinbase transaction. Therefore, the group specifies the size so that the miner knows how much space they have to work with Extranonce2.

Mining pools: if the transactions are changed in the memory, how do the miners know?

If Alicia asks for something to move it, Alicia sends her her public key and Bob encrypts the message using Alicia's password.

Bob uses his private key and hash function to make a signature.
After finishing this procedure, Bob sends an encrypted message with signature.

Finally, Alice decrypts the message and puts it into a hash function and compares the output with the decryption signature.

This is what I understood about the transaction.

But when the transaction is waiting in memory, if someone changes the content of the signature using Bob's public key, how is it possible that Miner knows that the signature is incorrect?

To compare the message with the signature, the miner needs Alice's private key. But the miner does not have.

Is there another way to compare the signature with the encrypted message?

mining pools – How to control an ethos platform miner remotely?

Apparently one of distinctive character The features are indicated on the device for remote restart and other configurations remotely.

How to control an ethos platform miner remotely?

Apparently, I need to edit local.conf case file. If so, how can I do this after restarting the miner?

I also want to see the situation of the miner through a control panel remotely. It's possible? And how?

Thank you

Mining pools – Hashrate Slushpool Miner always lower than local Hashrate

A short story

There is an Antminer server farm for which I provide support more than 100 BC Servers, mainly S9 and T9 models. There are three specific S9 miners that are side by side, side by side, in the frame, which continuously show a lower than normal hash rate in Slushpool.

When I check these servers in Slushpool, the three often fluctuate between 11-13 TH / s, but the web interface and the command line RT and AVH hash are always normal without fluctuations. However, every time I check Slushpool, it's almost always lower than normal and I've checked up to almost a hundred times in a single day just to make sure I was being conscientious.


Is there something common or something that someone else has determined that could cause a hash mining rate to always show lower in Slushpool than in the local server?


  • I have checked the command line and the web interface in all this and I see the same thing; Normal real time and normal average always
    Every time I check, but with Slushpool, it almost always shows that it's
    Lower hashing by 1 or 2 TH / s.

  • Normally, when other miners on this farm have a lower Slushpool hash rate than normal, the local servers have a value that correlates much more with that hash rate, so I'm
    trying to understand if there is something I do not understand here
    what can explain this.
