1.
As long as the basic independent broadband on the line, there is no demand for network speed
2. It adopts the P2P network mode and needs to be connected to the Internet
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 is a kind of currency generated on the network nodes and circulated on the network. It is the proct of the Internet
6. I accept three or four sets of RMB. Five sets can be exchanged at the bank now. The main purpose is to take photos of whether three or four sets of RMB are complete.

I know! Apple and Android have played! Solar2, when I played iPad, I paid a lot of money to buy them, because these 91 are convenient without the
Android. I installed several application management systems, and the answers posted on the website seem to be blocked
