1. For the benefits, jinwowo feels that the biggest benefit is to obtain great security. First of all, there is a central ledger, so it cannot be destroyed. As like as two peas, each node is only part of the system, and each node has the same rights. Destroying some nodes has no effect on the system at all. Secondly, you can't cheat, because unless you can control most people's computers in the system to make changes, the system will refer to the opinions of most people to decide what is the real result. As a result, it will find that it is totally meaningless to modify your own account book (because others don't admit it). Secondly, since there is no centralized intermediary, making everything run automatically through preset proceres can not only greatly rece costs, but also improve efficiency. Since everyone has the same account book, it can ensure that the process of account book recording is open and transparent.
2. blockchain technology will not affect efficiency and waste computing power. The key is to see how to innovate in a mode and how to use blockchain technology efficiently to achieve the effect of the mode
blockchain is essentially an encryption algorithm, which is based on the principle of hash 256 bit algorithm to achieve information security; The application of modern information will become more and more global and universal. Besides the basic requirements of anti tampering, anti repudiation and trustworthiness, the protection of privacy needs to be strengthened. The blockchain technology is proced because of the development of modern cryptography. The cryptography used today is the result of cryptography 20 years ago, Therefore, in order to apply the blockchain technology to more participation scenarios, especially in the Internet economy, more verification is needed to verify whether the existing encryption technology can meet the demand, and more in-depth integration of cryptographic frontier technology and continuous innovation are needed
as long as we use blockchain to make innovations in accounting methods based on our own mode, it will not affect efficiency and waste computing power, but will shorten the time and improve efficiency.

3. Blockchain is a decentralized distributed record book and a credit data system. Its advantages are obvious
1. What the Internet changes is the acquisition and transmission of information, while what blockchain does is the transmission of value
for example, on the Internet, we can easily and quickly generate information and it to any place. All information can be spread efficiently, but some valuable information that can only be transferred but cannot be shared often needs credit endorsement
for example, we can't the payment directly to the other party, but we need to subtract some money from the payment account and add some money to the collection account to complete the payment process. The current Internet protocol does not support the function of value transfer. The current value transfer is not direct transmission. Instead, it is endorsed by a centralized third party, such as Alipay, such as banks.
now these centralized organizations put all the calculation of value transfer in a centralized server, which will certainly involve the participation of people, which will cause many problems, such as some "finite theory" and "opportunistic behavior", which will make the whole behavior less credible. So there is a basic question, how to reach a credit consensus
this is how blockchain technology came into being. It can be said that blockchain can build a pure point-to-point value transfer system. Without the mutual trust of each node, blockchain can ensure the integrity and security of data records in the system, and can be separated from the endorsement of third-party organizations, effectively recing the complexity and risk of transactions
2. It is open and transparent, and can not be tampered with
all data of the blockchain can not be tampered with or deleted, and the information of the whole system is open and transparent. If someone owes you a sum of money, and now the data has been put on the blockchain, if he doesn't want to return it to you and play a rogue with you, you can go to the court to protect your rights through the data forensics on the blockchain, so as to get back your legitimate funds. Because the data on the blockchain is open to the whole network, the users of the whole network will know his rogue behavior, which will greatly increase his credit cost. Dishonesty will make him have an important impact in the next life.

4. MD5? That is to check the integrity of BT files, authenticity, must have seeds to be able to download
5. bitcoin is distributed accounting
bookkeeping is done by miners
generally speaking, the correct result of Distributed Accounting is decided by the vote of "miners"
if you have a 51% pool, you can theoretically void any transaction (roll back). This is called a 51% attack
now bitcoin miners are distributed all over the world. The world's largest mine pool is in China, and the person in charge of bitcoin has promised that its total power will not exceed 50% (now about 30%), so there is no possibility of 51% attack for the time being
but it can't be said to conquer

6. Convert to RMB for bookkeeping
7. It can be found that this is at the expense of a little bit of efficiency, and obtains great security. First of all, there is no big central ledger, so it cannot be destroyed. As like as two peas, each node is only part of the system, and each node has the same rights. Destroying some nodes has no effect on the system at all.
8. You can't cheat, because unless you can control most people's computers in the system to be modified, the system will refer to the opinions of most people to decide what is the real result, and it will find that it is totally meaningless to modify your own account book
