In the Internet era, computers have long proposed many trusted computing methods, that is, any blockchain technology node adopts a trusted computing module. Therefore, trusted computing can make technology upgrade and iteration in distributed networks easier.

In the blockchain technology of real-name registration system, there is a blockchain technology laboratory in the United States, and they have put forward many technical solutions from the real-name registration system. For example, the current blockchain technology is peer-to-peer, and many countries, such as South Korea, each country has an electronic certificate, which should be signed with real-name registration system's electronic certificate when trading. Of course, there are simpler solutions. We can store the IP address of the entire device as part of the transaction and store it in the blockchain application.

In this way, the whole blockchain technology transaction can realize the real-name registration system of technology. So this is an optional real-name registration system. We can set up a blockchain application network in real-name registration system or an anonymous blockchain application network.

Super key is also a great progress in the development of blockchain technology. Because of a distributed network, how can we supervise and control it? Cryptography, we call it multi-signature.

We (Yunbao Technology) design different blockchain application networks. If it is a blockchain application network used by banks, we can design a super key, and the keys of all nodes must be together with the super key to generate wallets.

Then this super key must be in the hands of regulators or some institutions, and their control over blockchain applications is limited. For example, the data on the current blockchain application cannot be deleted, so the super key can actually enable powerful institutions to modify the distributed network.

So what kind of technology is blockchain?

(1) distributed decentralization,

(2) There is no need to trust the system,

(3) Anti-tampering and encryption security. I know these words separately, but what do they say together?

1, distributed decentralization, this is everywhere on the Internet, needless to say, in short, there is no need for a central server, everyone's data is obtained from this server, just put the data on N devices connected to the network, and everyone can download and store it.

2. You don't need to trust the system. Do you trust the bank? Because the bank is recognized by the state, the blockchain realizes the trust method without a third party. N devices on the Internet are used to store data, and everyone can verify these data. As long as more than half of the people think you are right, you are right. No one or organization can modify more than half of the content on the Internet. If you don't trust others, you must always trust your own verification results. If you don't believe in yourself, congratulations, you are a great philosopher.

3. Non-tampering and encryption security

Blockchain adopts a series of technologies, such as SHA256, RIPEMD 160 and other cryptographic algorithms to ensure tamper resistance and encryption security. Such as 01011001165438. Of course this is just a simple example.
