Will bitcoin retrial succeed

1. When you transfer bitcoin to fire coin, how long it will arrive at the account is decided by the transferor. Generally, it is normal to arrive at the account within one hour and within 24 hours.
2. If it's a bitcoin wallet, then!!! My colleagues have not been able to log in the bitcoin wallet since August last year (they can only dig for dogs). The customer service is not online, so they can't reflect it, let alone log in, and the 6W principal is gone
3. 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?

4. The eldest son of Ethereum, ethereal fog
5. 1. The market of bitcoin is lack of supervision. The government and others don't know who the actual holder of bitcoin is.
2. Bitcoin can be exchanged anonymously between different currencies, and its acceptance abroad is still very high. That is to say, if you exchange bitcoin or consume bitcoin, the government doesn't know who consumed it.
3 The total amount of bitcoin is limited, and there is no issuer (central bank) that can adjust the overall situation, so it has the possibility of being a currency
4. The main market of bitcoin is in some areas where gray trading and black trading need to evade government regulation

4. The main market of bitcoin is in some areas where gray trading and black trading need to evade government regulation
6. First of all, bitcoin is a decentralized monetary system
for example, both RMB and US dollars are issued by banks, but bitcoin is similar to the treasure in a treasure hunt game. Everyone has the opportunity to "issue" bitcoin himself
in fact, the essence of special currency is a lot of special solutions generated by a lot of complex algorithms
the system will choose a correct answer every ten minutes. Whoever can find the correct answer in the first ten minutes will get a reward
the upper limit of bitcoin is 21 million. When bitcoin was born in 2009, each reward was 50 bitcoins
ten minutes after its birth, the first batch of 50 bitcoins were generated, and the total amount of money at this time is 50
then bitcoin grew at a rate of about 50 bitcoins per 10 minutes
when the total amount reaches 10.5 million (50% of 21 million), the reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, or 50% of 1050), the reward will be further halved to 12.5, and so on
therefore, bitcoin circulating in this mode can not be recovered to zero, because everyone is the issuer of bitcoin. Unless everyone clears their account number and no longer digs, bitcoin will always be active.

7. Bitcoin bitcoin cash has been a month since it was born on August 1. Many people were not optimistic about BCC before it was born, thinking that it would "die in the womb". But bitcoin cash is not as these people think, but shows tenacious vitality, and has achieved many good results this month
BCC, as a new type of blockchain asset generated by hard bifurcations of bitcoin, has a reason for its success
BCC maintains the goal of global point-to-point cash of zhongbencong
the proposal of BCC is not out of thin air, but to better realize the goal of "point-to-point encrypted e-cash system" described in the white paper of zhongbencong. For bitcoin, "Genesis block" is a pioneer. So no matter which fork you look at, whether it's bitcash, segwit2x or bitcoin core - there's one thing in common. They're all from the genesis block on January 3, 2009. Bitcash (BCC) maintains the goal of global point-to-point cash of zhongbencong, while the isolation witness plan turns bitcoin blockchain into settlement layer. On the second layer, lightning network center and other settlement schemes in the second layer will provide charging services to complete transactions faster
therefore, compared with most competitors, no matter which chain they are in, most of the coins have been g out, and there are only a few left. This creates the scarcity of digital currency, which creates value. The EDA (emergency difficulty adjustment rule) of bitcoin cash is also a very important step to ensure the survival of the coin envisaged by Nakamoto
no congestion and low handling charge are the key to the success of BCC
for the original bitcoin chain, the biggest problem now is transaction congestion and high handling charge. But these problems don't exist for bitcash. Because BCC removed segwit and removed the block size limit of 1m, there is no block size limit problem. This means that the use of bitcoin cash will not lead to transaction accumulation, so transaction fees will be lower. Compared with the average transaction fee of bitcoin original chain at $10, BCC costs only a few cents or less. With the advantages of transaction costs highlighted, many online enterprises and business accounts will join the BCC ecosystem to create a better payment system
BCC is the choice of the market and users
the success of BCC depends on the support of the market and users. No matter how good the proct is, it will be worthless if it leaves the users and the market.. Although BCC has changed the original intention of bitcoin technology, it is a new technology attempt, there are still many uncertainties in the future, but the emergence of BCC has also solved many problems. BCC has achieved rapid expansion through hard bifurcation, which solves the problem of transaction congestion of bitcoin for a long time. The large block owned by BCC can make the transaction faster and cheaper, which can truly realize the "point-to-point encrypted e-cash system" mentioned in the bitcoin white paper. This is unmatched by bitcoin in the short term. In order to solve the problem of bitcoin network congestion, the community has been arguing about it for a long time, but there is no good solution to put it into practice. The emergence of BCC makes this problem not only stay in controversy and theory, but also find a better solution through practice. As for how BCC will develop in the future, it still needs time and market to witness.
