1. Jinwowo analysis believes that blockchain mainly solves the trust and security problems of transactions. Once the information is confirmed and added to the blockchain, it will be permanently stored. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of data on a single node cannot be realized. Therefore, the data stability and reliability of blockchain are very high
e to the use of Distributed Accounting and storage, there is no centralized hardware or management organization, the rights and obligations of each node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system.

2. Give you an easy to understand example, you can quickly understand what blockchain is:
in a village, a spent 3000 yuan to buy a cow of B, how to record this account
so a and B found a mutual trusted C to record the account, but later a and C colluded and did not admit that a had bought B's cattle, so the deal became rough and disputes continued
later, B had another cow. Of course, B didn't sell it to a this time, because a had no credit, so he gave it to d. This time, instead of looking for witnesses, they went to the whole village to roar after the transaction. B said Wang Erhua paid 3000 yuan to buy a cow from me, d also went to the whole village to shout that I paid 3000 yuan to buy a cow from B, so there were many people in the village to record the transaction. In this way, there will be no bad debts, which is called decentralized and distributed accounting
here comes the problem
when you yell, are the villagers willing to charge for you, just because you have a big face
therefore, the first person to record accurately will get some bitcoin rewards
someone asked, what if two people finish the first record at the same time
in order to avoid this problem, it is necessary to set rules, for example, to answer a question first, or to record with feet, and it must be written in block letters. If you set a series of rules, there will not be many firsts
in the network, there are a lot of transactions going on every day, and there are also many people recording, and finally they get the reward of bitcoin. This process is the legendary mining
Mining requires a lot of equipment. We call these computer equipment mining machines
in this way, all the processes are in one system. The system will encapsulate the data every 10 minutes to form a box full of data, which we call blocks
with the continuous generation of blocks, they are linked together to form a blockchain.

3. There are almost all of them on the Internet, but the content is not well distributed, so it must be a new technology. In depth understanding can be obtained through some R & D companies and blockchain media, such as Heshu software, blockhouse, Heshu media, blockchain 110 and other websites. I hope I can help you. Thank you
4. Here is about what blockchain is, but if Xiao wants to have a deep understanding of blockchain, he still needs to read more relevant articles
blockchain is a decentralized distributed ledger. Blockchain is not something. You can think of it as the Internet. No one will think that the Internet is an object. Blockchain is a new model. If we think of it as an account book, it means that all transaction information is in this book. Due to the characteristics of decentralization, it is not subject to the jurisdiction of a third party
blockchain is a decentralized database in essence. Once the contents in the database are recorded in the chain, they cannot be tampered with, and all the contents can be traced back to their source. The centralized procts may be tampered by the jurisdictional party. Therefore, blockchain traceability is also commonly used to trace the source of goods
there is still a lot of knowledge about blockchain, which is just a simple concept. In depth understanding, we need to take time to look at the news and learn about its landing applications. We can see more about password finance.

5. We should first understand from the concept, know what is blockchain, know what the mainstream currencies have, read more hot information, see more about how other big V evaluate this instry, what their views are. First, don't blindly follow the trend, understand more about the market, and you can't eat hot tofu in a hurry. It's recommended that you go to hubox to have a look, which will help
6. Do you mean wood? It can be mined in a mine, decomposed in a furnace, or bought in a shop, but it's not cost-effective. It's mainly mining and decomposition equipment
7.
8. It's better not to follow the trend and participate. There are too many MLM and fraud projects in the blockchain, so it's hard for ordinary people to distinguish.
