Mining is 00hash

1. What else do you need to set? My two computers, the power supply is overclocking three a 6, can't two computers are power problem? In addition, when I dig p2pool, the mining speed of the two graphics cards is normal, and each one is more than 100 mhash / s. I may have found the reason myself. I just chose btcguild (Florida, USA) [btcguild (any) was the first choice] on the server of guiminer, and the two graphics cards returned to normal. Contact the problem announced by btcguild two days ago, which can explain why btcguild server was attacked.
2. We know the process of information computing hash packing: transaction record, time, account number, last hash value. We also know that all calculation and storage need to consume computer resources. In Nakamoto's design, the completion of bookkeeping can be rewarded with bitcoin by the system, which is also the process of issuing bitcoin. Therefore, bookkeeping becomes mining
bookkeeping
because bookkeeping is a reward, each time you can add a certain number of bitcoin for yourself, so everyone is competing for bookkeeping, which of course leads to a problem: when there is inconsistency in bookkeeping, the system introces workload proof to solve the problem, and the rules are as follows:
1. In a period of time, only one person can succeed in bookkeeping
2. Obtain the unique bookkeeping right by solving the cryptography problem
3. Other nodes the bookkeeping results
but before the workload proof, The accounting node will do the following preparatory work:
1. Collect the original transaction information that has not been recorded in the broadcast
2. Check whether the payment address in each transaction information has enough balance
3. Verify whether the transaction has the correct signature
4. Package and record the verified transaction information
5. Add a reward transaction: add 12.5 to your address Bitcoin
if you succeed in competing for bookkeeping rights, you can get a reward of 12.5 bitcoin
workload proof
the hash value of the previous block and the current account page information will be hashed together as the original information in each bookkeeping. In order to ensure that only one person can keep accounts around 10 minutes, we have to improve the difficulty of keeping accounts. The results of hash must start with several zeros. In order to satisfy the condition, hash is to introce a random number variable
denoted by pseudo code:
1. Hash (last hash value, transaction record set) = 456635bcd
2. Hash (last hash value, transaction record set, random number) = 0000afd635bcd
if you change part of the original information of hash, the hash value will also change continuously. Therefore, when you run hash, the value of random number will change continuously, A random number can always be found so that the result of hash starts with several zeros. The node that finds the random number first obtains the unique bookkeeping right
verification
after the node successfully finds the hash value, it will broadcast and package the block to the whole network immediately, and the node of the network will verify it after receiving the broadcast. If the verification is passed, it indicates that a node has successfully decrypted, it will not compete for the current block, but will choose to accept the block and record it in its own account book for the next round of competitive guessing. Only the fastest decrypted block in the network will be added to the ledger, and other nodes will to ensure the uniqueness of the whole ledger
If a node has cheating behavior, it will cause the node of the network to fail the verification, give up its packaged block directly, and cannot be recorded in the general ledger, then the consumption cost of the cheating node will be in vain. Therefore, miners consciously abide by the consensus protocol of bitcoin system, and ensure the security of the whole system
it's like you go to the construction site to move bricks. After moving bricks for one day, the contractor asks you how can you prove that you move bricks for one day?

3. Your efficiency is too low. The speed I calculated with the graphics card is 226mhash / s, and the current ASIC device can reach 60g / s, so it seems that your speed will not contribute.
4. Every day, you can find an NPC to send it to the mine cave for half an hour. You can get black iron ore by mining, and you also have a chance to trigger the boss of the mine cave! But the deeper the mine is, the more dangerous it is. Please be more careful
after entering the mine cave, you can find a wall and click a mining button beside the shortcut skills bar. If you click Yes, it will automatically mine
in mining, not only black iron ore but also slag can be found, and slag can be exchanged for black iron ore by NPC
comments: mining is a good way to get black iron ore, you can dig in your spare time!

5. At 170mhash / s, the 24-hour output is only 0.1 bitcoin... I also turn.. Wow, there's this in it? I don't understand at all..
6. The European Court of Justice announced that bitcoin and other virtual currency transactions will not be subject to tax

I contacted btcguild's official website two days ago about the attack, Can make btcguild server reason.
8. Let's take a look
9.
I believe there is a fraud in issuing digital currency, but there is a fraud in mining. Unless you buy a "nonexistent" mining machine or computing power, the probability of being cheated is almost zero. Next, let me talk about UTC's past and present lives
So, it's hard to say whether UTC is a fraud, but this model is indeed an innovation in the currency circle. After all, digital currency is getting more and more attention, and it may not become "currency", but it may become "alternative investment goods". Personally, I'm optimistic about this mining modelmoreover, as far as I know, the team behind UTC, as well as the financial and technical support are quite reliable. If it is really a scam, the institutions that invest in UTC will not make such a big battle to cheat people
