1. First, register and log in by email, and the second picture after login is the receiving address of bitcoin. If you want to pay to this address, you can transfer money to this address by using bitcoin wallet, or withdraw money to this address by using exchange

Lightning network is known as one of the most effective cryptocurrency expansion solutions currently being developed. The scheme was proposed in 2015, based on a network at the top of bitcoin blockchain, and finally implemented on the network. The network consists of user generated channels that send payments back and forth in a secure and untrusted manner
For example, suppose I want to pay for every minute I watch. We're going to open up a lightning channel, and as time goes on, we're going to make regular payments from my wallet to the video makers. When I finish, we will close the channel to settle the net balance on the bitcoin blockchain. Because transactions are only between me and the other party and do not need to be broadcast to the whole network, they are almost instantaneous. And because there is no incentive for miners, the transaction cost is low, or even no transaction cost at all
3. Compared with bitcoin, the biggest advantage of bitcoin cash (BCH) in payment is that the network is not congested, transaction fees are low, and zero confirmation payment is supported
bitcoin cash is the proct of the competition for bitcoin expansion. It is a large block version of bitcoin. At present, it has been expanded to 32m. In the short term, it is impossible to have the problem of network congestion, and bitcoin cash will continue to expand according to the market demand
bitcoin is still locked in 1m block size, which leads to the congestion of bitcoin network, and the number of unprocessed transactions is amazing. Isolation verification and lightning network have not solved the problem of bitcoin network congestion.

4. Bitcoin adopts the Internet-based P2P (peer-to-peer) network architecture. P2P means that each computer in the same network is peer-to-peer, each node provides network services together, there is no "special" node. Each network node is connected with each other in a "flat" topology. There is no server, centralized service and hierarchical structure in P2P network. P2P network nodes interact and cooperate: each node provides services to the outside world, but also uses the services provided by other nodes in the network. P2P network is reliable, decentralized and open
the P2P network structure adopted by bitcoin is not just the choice of topology. Bitcoin is designed as a point-to-point digital cash system, and its network architecture is the reflection and cornerstone of this core feature. Decentralized control is the core principle of design, which can only be achieved by maintaining a flat and decentralized P2P consensus network
each node in bitcoin P2P network is peer-to-peer, but according to the different functions provided, the division of labor of each node is not the same. Each bitcoin node is a functional set of routing, blockchain database, mining and wallet services. A bitcoin network node includes four functions: wallet, miner, complete blockchain and network routing node
some nodes keep a complete and up-to-date of the blockchain, which is called "all nodes". The whole node can independently verify all transactions without any external reference. In addition, some nodes only retain part of the blockchain, and they complete transaction verification through a method called "simple payment verification (SPV)". Such a node is called "SPV node", also known as "lightweight node"
mining nodes create new blocks in a competitive way through proof of work (POW) algorithm running on special hardware devices. Some mining nodes are also full nodes, keeping a complete of the blockchain; There are also some nodes involved in the mining of the mine pool, which are lightweight nodes, and they must rely on the whole node maintained by the mine pool server to work
User wallets can also be used as part of the whole node, which is common in desktop bitcoin clients. At present, more and more users' wallets are SPV nodes, especially bitcoin wallets running on resource constrained devices such as smart phones, which is becoming more and more common.

5. Political function and economic function
because bitcoin has the following potential risks: first, high speculative risk; Second, high risk of money laundering; The third is the risk of being used by criminals or organizations. From the perspective of maintaining national security and social stability, it is a political function; It is an economic function to manage and supervise the enterprises and the market by ensuring the smooth operation of the market, ensuring fair competition and fair trade, and safeguarding the legitimate rights and interests of enterprises
bitcoin home has the notice and interpretation about the central bank and other five ministries and commissions
from the current situation, because the total amount of bitcoin is small, the scale of trading market is limited, and financial institutions are not directly involved in trading and investment activities. As long as necessary prevention and control measures are taken, the risks brought by bitcoin and other virtual commodities can be avoided to impact the financial system and affect financial stability and monetary policy. At the same time, as a virtual commodity, bitcoin's price fluctuation is not related to the real economy, and the scope of real economy transactions priced and paid by bitcoin is extremely limited. We can also strengthen prevention and control to avoid bitcoin and other virtual goods to impact the real economy. However, e to the high risk of speculation, money laundering and being used by criminals or organizations, bitcoin and other virtual commodities are still worthy of attention
since the emergence of bitcoin China, the first bitcoin trading website in China in 2011, dozens of similar virtual commodities have appeared in China in just a few years, and more than ten trading websites of bitcoin and lettercoin and other similar virtual commodities have been set up. The daily bitcoin trading volume in peak period accounts for more than half of the world's bitcoin trading volume. With the help of the concepts of "internet currency", "future trend" and "digital gold", the trading of bitcoin and other similar virtual commodities has changed from simple trading to high-risk speculative activities such as "financing currency" and leverage trading. Compared with bitcoin, there is still a lack of sufficient understanding of bitcoin and a large number of ordinary people participate in it, Holding, using and trading bitcoin out of the mentality of following the trend or speculation will cause great losses. If it is not restricted, it will not only affect the seriousness of RMB as China's sovereign currency, but also damage the property rights and interests of the public.
