Almost every friend who comes into contact with bitcoin will have a question: what is the exact amount of money spent digging Bitcoin? It is hard to answer this question even for a professional 'miner.' Some even say that bitcoin The calculations are spent on research, such as finding the next 'Earth', decrypting DNA, etc. This interpretation seems plausible to anyone who does not know bitcoin, but that's not the case.
To solve this problem, you need a bit of understanding of Bitcoin.I recommend everyone to see the paper "bitcoin: a point-to-point electronic cash system," which is the source of bitcoin.This paper relates to why bitcoin , How Bitcoin generates knowledge, etc. It is also this essay that answers the question of what to do with digging Bitcoin.
In order to answer this question, we need to start from why we should start with Bitcoin. In order to avoid the readers feel that trouble, I will publish the answer here: In fact, the answer to this question is not everyone imagined 'to serve the society and serve science' Services bitcoin network, to ensure the security of bitcoin network.
The purpose of bitcoin is to remove the middle part of the transaction, which is the financial institution. To do this, Bitcoin needs to establish a set of proof systems. Why? For example, A lends money to B and the intermediate process Need to sign a note, notarization and other proofs that A does lend money to B. If there is no proof, B can be denied, A can only recognize planted in the traditional course of the transaction, financial institutions have played a role in proving. Why is a financial institution, because he has credibility, credit endorsement.
Bitcoin network computing trends
So how does bitcoin prove that A loaned money to B? The idea behind Bitcoin is to keep the news in the books, and then see it all, so everyone knows that A lends money B, how much borrowed, when borrowed, so B can not denied this fact.
To let everyone know a transaction information, this is the proof of bitcoin system. But there is a problem, the problem is the 'double payment'.
Calculating the power is to maintain the security of the Bitcoin network
Before explaining, you need to explain how much money you have in Bitcoin network, not for the sake of your decision, but for everyone to make ends meet. Everyone is a notary public.
Double payment is a sum of money spent twice, this situation is impossible on banknotes, but because bitcoin is not kind, but 'bookkeeping', there is no exchange of substance in the middle, so it can happen. For example: A bought a B with 1000, B recorded in a book; the same time, A bought the same C 1000, C recorded in a book. At this time B to sleep, and C to just remember The account for everyone to see, B woke up before we show for everyone.
In order to solve this problem, the Bitcoin network makes the transaction irreversible, that is, it can not be refunded before the shipment of B and C. 1000 The irreversible characteristics of the two 1000 transactions of A are only Admit one.
First, Bitcoin transforms all transactions by random hashing and timestamping, prioritizes transactions, and trades into the chain based on a proof of workload based on random hashing. Adult words are: B and C books to show you read, there will be people continue to book in this account.
If most of the people behind the book choose to book the B's book, then everyone will B's book as correct, and B's account book, remember A bought 1000 with B things, so A 1000 belongs to B, C will not be recognized, B shipped to A on it.
A chain based on the workload of random hashing
In this process, you need to calculate the power, the calculation is to ensure that the block information can not be changed.How to achieve it? Workload proof is based on random hash, and then form a chain.This chain has a characteristic, you want to start with Need to solve, you need to calculate the power.And the difficulty of this solution is exponential growth.If you first find the solution, you get the bitcoin reward.
But if you want to modify a block that has already appeared, you have to pick the one with the longest chain and solve it from the beginning so that the chain you modify is considered correct (the longest chain is considered the correct one, not Understand it, you can contact the previously mentioned B's book.) But this longest chain has the greatest amount of work under the entire network, all of the words need to spend huge computational burden.
And doing so outweighs the benefits, because you spend so much effort trying to modify the results, not as good as you taking the power to solve the high income.This will ensure that no one to change the information before the block, block The information is naturally immutable, and the 'immutable' can be changed, but no one can ever do it.
In other words, digging bitcoin's computational power is essentially always solved, so that the longest chain can guarantee the maximum workload of the entire network, so that will not be changed.This also achieved the bitcoin system is solid , Will not be attacked.
Is this meaningful if it makes sense?
We first look at these calculations.Currently Bitcoin's full network computing power is very high, is said to have more than the world's top 100 supercomputer count the sum of power are stronger.This view has some misleading, bitcoin network As long as it is to seek an algorithm, that is, SHA256 algorithm HASH value, which is the workload of bitcoin network proof of the mechanism requirements.That is, the bitcoin network in solving SHA256 algorithm HASH value calculation is very powerful.
The bitcoin network's power to solve other algorithms? The entire bitcoin network computing power may not have your computer computing efficiency .This is because bitcoin network computing power is too professional, but It can not do any other work to solve HASH value of SHA256 algorithm, which is why, even if you use GTX1080Ti to mine, it is not as fast as the worse performance of mining machine.
And even if you use the power of bitcoin networks to dig coins based on other algorithms, the efficiency is very low.
In other words, the power of bitcoin networks is valuable, ultimately depends on whether people will admit that bitcoin is not a currency.If everyone admits bitcoin, then the bitcoin network will be the safest financial system in the world. Point of view, bitcoin network computing power is too valuable!
If bitcoin is not recognized as a currency, then the value of bitcoin networks is very small, as small as possible, and the price of bitcoin is completely up and full of bubbles.
These two conclusions are derived after the bitcoin is qualitative, the current bitcoin is not the currency is not yet qualitative.However, bitcoin has not become a recognized currency, so it seems now, the largest bitcoin network computing power The value is that bitcoin can dig up and sell it, and Bitcoin is more like a commodity.
Finally, to answer the question at the outset, what are the bitcoin's calculators used to do? Too big to say is to maintain the security of the bitcoin network, to the small to say that it is in the count; to spend so much effort to achieve significant value It's not easy to say why there are so many people mining because they can make money ah!
