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. Well, it depends on the model. In fact, it has nothing to do with the graphics card and the brand. But the computing power is stable. It's better to choose the brand machine. After all, the connection of the machine is better than that of the general assembly machine

5. 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.

6. Bitcoin is a distributed account book. There is no core server. As long as there are records in six blocks, the transaction records and accounts are legal
uniqueness is that your account is unique. Each user has only a portion of all user account records
those less than 1 bitcoin can also be traded. There is a bitcoin exchange and you can exchange them with any existing currency
the account is anonymous, just a string of codes
the essence of money is a credit certificate. You can understand it as an IOU. Bitcoin itself is not money, but because of its concealment and decentralization, it can act as a credit certificate for cross-border settlement, avoid the supervision of various rights, and facilitate money laundering. Therefore, bitcoin becomes money.
