1. This is not necessarily true. After all, it is a digital cryptocurrency, each of which is separate and not stored on the website.
2. I don't know what you mean
3. Qube exchange answers for you:
1) new transactions broadcast to the whole network
2) each node brings the received transaction information into a block
3) each node tries to find a workload proof with enough difficulty in its own block
4) when a node finds a workload proof, it broadcasts to the whole network
5) if and only if all the transactions contained in the block are valid and have not existed before, other nodes agree with the validity of the block
6) other nodes indicate that they accept the block, and the method of indicating acceptance is to follow the end of the block, create a new block to extend the chain, and regard the random hash value of the accepted block as the random hash value that is faster than the new block
hope to help you.

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. Bitcoin (English: bitcoin, abbreviated as BTC or XBT) is a kind of cryptocurrency based on decentralization, adopting point-to-point network and consensus initiative, open source, and blockchain as the underlying technology. Bitcoin was published by Satoshi Nakamoto on October 31, 2008, and Genesis block was born on January 3, 2009. In some countries, central banks and government agencies, bitcoin is regarded as a virtual commodity rather than a currency
anyone can participate in bitcoin activities, which can be issued through computer computing called mining. The number of bitcoin protocols is capped at 21 million to avoid inflation. Bitcoin is used as a digital signature through the private key, which allows indivials to pay directly to others. It is the same as cash, and does not need to go through third-party institutions such as banks, clearing centers, securities dealers, electronic payment platforms, so as to avoid high fees, cumbersome processes and regulatory problems. Any user can use it as long as he has a digital device that can connect to the Internet
however, e to the limited transaction volume that bitcoin blockchain can accept in a certain period of time, it can accept up to 2500 transactions every 10 minutes, and the transaction handling fee will fluctuate with the transaction volume of bitcoin. In June 2017, the transaction handling fee of less than 1 millibit has been far greater than the transaction amount; In December 2017, steam announced that it would stop accepting bitcoin because of "high transaction costs and high volatility". In February 2018, the average transaction handling charge dropped from $34 in the fourth quarter of 2017 to about $1. This problem is being solved by technologies such as lightning network to expand the transaction volume of bitcoin within a certain period of time
P2P can refer to:
peer-to-peer, a network technology and network topology
file sharing, often using point-to-point technology
point-to-point protocol, which is used for dial-up computing, is usually abbreviated as PPP
Peer-to-Peer Lending, also known as P2P lending, is also known as Internet lending and P2P financing in Chinese mainland.

7. Litecoin is a kind of network currency based on "peer-to-peer" technology, which can help users pay to anyone in the world immediately. At present, lightcoin is the second virtual currency after bitcoin in global circulation market value. The legends of bitcoin, Wright silver, infinite copper and pennies aluminum (Internet) are popular in the circle. The popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, BBQ coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Litecoin is inspired by bitcoin (BTC), and has the same implementation principle in technology. The creation and transfer of litecoin is based on an open source encryption protocol, which is not managed by any central authority. Litecoin aims to improve bitcoin. Compared with bitcoin, litecoin has three significant differences. First, the liteoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the output of litecoin network is expected to be 84 million litecoin, which is four times the amount of currency issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in litcoin's workload proof algorithm, which makes it easier to mine litcoin on ordinary computer than bitcoin. Each litecain is divided into 100000000 smaller units, defined by eight decimal places. Lightcoin needs to be generated by "miner's mining". Mining is done by hashing with computer graphics card. If the value of "mine burst" is calculated, the system will reward 50 lightcoin at one time. At present, the computing power of lightcoin is growing rapidly, and miner can't dig mine through several computers. Therefore, it needs to be added to the mine pool, which collects all the computing power, It is estimated that the probability of calculating the "blasting" value is higher. At present, the well-known ore pools abroad include: wemineltc, coinotron, etc
8. Abstract: a person named Satoshi Nakamoto posted a post on the P2P foundation website, saying that he has developed an open-source P2P (peer-to-peer) e-cash system called bitcoin, which is completely decentralized. There is no central server or trustee, and everything is based on participants. Bitcoin Bitcoin is a kind of virtual currency in the form of P2P. Point to point transmission means a decentralized payment system. Bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. Bitcoin is a kind of network virtual currency, similar to Tencent's q-coin. You can use bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system has no more than 10.5 million in the first four years, and the total number after that will be permanently limited to 21 million. Another point is that you can use computers to make bitcoin. Bitcoin is an electronic currency proced by open source P2P software. Bitcoin has also been paraphrased as "bitgold". The concept of virtual currency bitcoin was first proposed by Satoshi Nakamoto in 2009. Now bitcoin is also used to refer to bitcoin's open source software designed and released according to the ideas of Satoshi Nakamoto and the P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution, but uses a distributed database throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. For example, bitcoin can only be used by its real owner, and only once, after the payment is completed, the original owner loses the ownership of the bitcoin. Feature bitcoin is designed to allow anonymous ownership and use rights. Bitcoin can be stored in personal computer in the form of computer file (wallet) or in a third-party hosting service. No matter how it is saved, bitcoin can be sent to anyone on the Internet through its address. The distributed characteristics of P2P and the design of no central management mechanism ensure that no organization can manipulate the value of bitcoin or create inflation.
9. There can't be inflation. What is inflation? There are two kinds of inflation:
(1) suppose that one sheep can exchange for 10 chickens. There is one sheep and 10 chickens in a room, which issue 200 yuan currency, so sheep is worth 100 yuan and chicken is worth 10 yuan. If we issue another 200 yuan, the price will double, and the sheep value will be 200 yuan, which is the inflation of issuing excess currency
(2) in the above example, when 10 chickens are eaten, the room is still 200 yuan, and only one sheep is worth 200 yuan. This is inflation e to shortage of goods, and there is no issue of more money< (3) the collection of bitcoin itself loses its monetary function. Money is only an intermediary and develops from barter. So you are right, all collections will lose the function of currency
(4) if there are few things, the same currency is also inflation, so no matter what the currency is, virtual currency and limited currency will also be inflation.

10. It is the concept of virtual currency
bitcoin, which was first proposed by Nakamoto in 2009. According to Nakamoto's idea, it designs and publishes open source software and constructs P2P network on it. 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 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 currency circulation.

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items< On February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
