Zhihu Ethereum
The remitter will pay bitcoin directly to the other party according to the address of the payee through the computer or smart phone
after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed
the bitcoin peer-to-peer network stores all transaction history in the "blockchain". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. In fact, blockchain is a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history

extended data
special attention:
1. When purchasing and selling bitcoin, it is necessary to deal with it in time, and do not need card orders. For example, after placing an order, you need to pay in time and click paid. After others pay you, you need to put money in time. Otherwise, the other party will appeal to Huo coin
2. The collection account must be filled correctly
3. The risk of currency market is high and investment should be cautious
after buying bitcoin, if you want to change it into other currencies, such as EOS and Ethereum, you can go to the currency trading platform and directly click the hanging order to sell it and change it into other currencies you want. If you want to change money, you can sell it on the off-site platform. People who need to buy will contact you, operate on the platform, and then pay offline< strong>
POW: full name of proof of work
pos: proof of stake
both of them are the consensus mechanism of blockchain and the bookkeeping method of digital currency
the difference is:
1. POW mechanism: workload proof mechanism, that is, the proof of workload, is the requirement that must be met when generating a new transaction information (that is, a new block) to be added to the blockchain. In the blockchain network based on workload proof mechanism, the ability of nodes to obtain the correct numerical solution to generate blocks by calculating the numerical solution of random hash hash is the specific performance of node computing power
POS mechanism: the proof of rights and interests requires the certifier to provide a certain amount of ownership of cryptocurrency. The operation mode of the proof of rights and interests mechanism is that when creating a new block, the miners need to create a "currency right" transaction, and the transaction will send some coins to the miners themselves according to the preset proportion. According to the proportion and time of token owned by each node, the equity proof mechanism reces the mining difficulty of nodes proportionally according to the algorithm, so as to speed up the speed of searching for random numbersextended materials:
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. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
popularity: there is no doubt that bitcoin and lightcoin have the highest popularity in the cryptocurrency circle. Even though they have many shortcomings, they still have the largest number of players and the highest amount of money. They have large plates and are not easy to be controlled by the makers. Of course, the relevant infrastructure is relatively perfect
Innovation: dog coin is popular because it caters to the western small reward culture. The reason why Fuyuan coin can become the leader of the new generation of cryptocurrency is that it mainly focuses on the currency business circle, which is an applied cryptocurrency
operation mode: for example, the operation mode of Vicat coin has been exposed as pyramid selling. Although Yuanbao coin has been criticized before, the operation team will not give up, and Yuanbao coin is still the leader of domestic currency.
Yingtai Digital Theory: after the implementation of digital currency, it will coexist with banknotes and coins for a long time. Whether it can completely replace banknotes and coins in the future is still unclear
of course, with the implementation and graal maturity of digital currency, the use of digital currency will be more and more, and the use of banknotes and coins will be less and less. These banknotes and coins will slowly enter commercial banks through residents' storage or exchange of digital currency, and then commercial banks can use them to exchange digital currency with the central bank
Virtual currency is a hot topic in recent years, and many people have made a lot of money because of it, but the current situation of these people is so sad
some people become famous and realize the freedom of wealth, while some people continue to speculate like gamblers and lose everything
this kind of people all heard that other people made money from it, and then they regretted very much. Why didn't they buy a few bitcoins in those years
then, in order to make up for this regret, these people are crazy, looking for this coin and that coin every day, spending all their savings, but in the end, few of them increase their prices
you should know that scarcity is the most important thing. Now all kinds of virtual currencies have been saturated for a long time. What's the use of joining in this? If you don't say anything else, just bitcoin, a lot of people can't do it, OK
