How to confirm each node of blockchain

1. The information of each block in the blockchain is different, and the generation time and recorded data of each block are different. You can regard the blockchain as a bookkeeping book. Every once in a while, someone will write all the transaction information on the blockchain network to one page of the ledger, page by page, and record all the transactions on the blockchain network in turn according to the time
on the other hand, all nodes (computers in short) participating in the network will store one account book, which is updated in real time. Even if one node fails, the blockchain will not be affected.

2. bitcoin blockchain is a bitcoin blockchain? No, the block stores the transaction. In the early stage, you will get a coin if you successfully build a block. In the later stage, you can only get the fees paid by the exchange. A currency is a string of digital signatures. It is a digital signature sent by the last owner to the receiver. Everyone can see who owns the currency from the transaction
does each node have complete blockchain data? You mean a user node? A user node needs to keep the of the block head of the longest workload proof chain, so it knows the data of all the block heads. It can move forward to know all the data on the block chain, but not all of them are saved. A block header is very small, only 80 bytes, which can be saved completely, because the generation of nodes is very slow. Even with the passage of time, the amount is not too large now.

3. The decentralized nodes in Chongqing jinwowo analysis blockchain technology are as follows:
every central node can generate blocks and write data, so every point is a central node, or the blockchain is decentralized. In order to control the whole system, more than half of the nodes must be controlled in order to control voting, so there is no administrator in this system.

4. A lot of network, or in a group said easy to understand. Teach you to understand with mathematical knowledge (node is a point, block is a line, and blockchain is a surface). Node is the basic unit of information processing in blockchain application technology. After processing information, many nodes will be timestamped, generate data blocks, and connect blocks in time sequence to form blockchain.
5. Jinwowo analysis: a node is actually a computer (server) connected to the blockchain. Any connected computer can access the blockchain, so there are countless nodes on the blockchain; However, the number of blocks on the blockchain is limited, that is, one block is generated every 10 minutes, and no new blocks will be added after reaching a certain number.
6. It depends on whether you invest. If you don't invest, you can make money by checking in every day. If you invest in the miner, the income will be higher.
7. The node of blockchain technology is: in order to confirm the validity of the transaction, bitcoin needs more than one indivial network to process the transaction order, and it must broadcast to the network through the "node". This is the first step in the transaction processing process (blockchain confirmation)
to fully tap the potential of the network, bitcoin network should not only provide trading channels, but also ensure security. Using randomly selected nodes, the network reces the double spending problem - the possibility of users trying to spend the same digital currency twice. However, bitcoin requires more than nodes, it also requires many nodes that work hard - those nodes that upload bitcoin core clients and complete blockchain in a machine entity. The more nodes, the more secure the network
for example, each node is equivalent to a server. In this P2P network, messages must be disseminated and finally recorded and stored by most servers before they are confirmed.
