Is bitcoin a success or a failure
bitcoin is just a game. If it is promoted as a tool to get rich, it can be regarded as a fraud. Just like the currency in other online games, the only difference is that bitcoin has been standardized since the game was first formulated. It can't be issued indiscriminately, so it can keep its value better than other virtual game props. It is equivalent to the online collection. Bitcoin is a prop in the game, and its value is reflected in the recognition of bitcoin by players: more people play, the value of props in the game is higher; The risk is that he is not the only game, and his algorithm is not the only one. Maybe someone will be able to make other special coins soon. All you need to do is promote the game and sell your props. As for money, bitcoin does not have the basic attributes of money, such as unfair initial distribution and insecure circulation. Money needs to be maintained by the state machine
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
3. On May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked
4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30

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?
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.
you may not quite understand the difference between "bitcoin" and "bitcoin trading market". It's just that I heard that a bitcoin or something is going to go bankrupt. The bankrupt is "bitcoin trading market", not "bitcoin". Pay attention to the difference
just like a company selling potatoes, potato trading company, it is "potato trading company" rather than "potato" that goes bankrupt
bitcoin, like potatoes, is a commodity. How can a commodity go bankrupt?
bitcoin protocol is designed to issue new bitcoin at a fixed rate. This makes bitcoin mining an extremely competitive instry. As more and more miners join the bitcoin network, it becomes more and more difficult to make profits. Miners must seek efficiency to cut proction costs. No central authority or developer has the right to control or manipulate the system to increase their profits. Any behavior that does not comply with the rules required by the system will be rejected by any bitcoin node in the world
bitcoin is issued at a predictable and graal rate. The number of new bitcoins will be halved year by year until the total number reaches 21 million. By then, bitcoin miners may be able to support only a large number of small transaction costs.
