Fu 700 and blockchain

1. The difference between code chain and blockchain:
blockchain originates from the underlying technology of bitcoin and is the blockchain technology of Internet. IP is connected by blockchain technology to form distributed accounting. It is not easy to tamper with and decentralize
code chain technology is the code chain technology of the Internet of things, which superimposes the Internet of things IDS one by one in a two-dimensional way to form personal records. The application of "code chain" technology will bring more efficient link forms of "people to people", "people to things" and "things to things"
Introction to code chain:
"code chain" refers to a "two-dimensional code chain" formed by using a smart phone to aim at the "two-dimensional code" and "scan", that is, to "generate a new two-dimensional code containing the scanner's DNA" and access to the "service". The whole process can be traced, supervised and managed
"code chain technology" is the most widely used two-dimensional code "scan" payment technology
code chain technology can realize more efficient link form of people to people, people to things and things to things
Introction to blockchain:
blockchain is an important concept of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
the difference between code chain digital currency and blockchain digital currency:
the difference between "code chain digital currency" based on code chain technology and the existing blockchain digital currency is that "code chain digital currency" is based on the control of property rights, and uses "intelligent two-dimensional code" as the medium to transform the contracts of various instry chains into divisible, tradable, transferable, exchangeable Traceable "smart contract" and real right exchange within the code chain alliance. In the code chain monetary system, "intelligent two-dimensional code" means "SGR". That is to say, each commodity corresponds to a "smart QR code", and this "QR code" represents the "special reference property" of the commodity. Through special reference to the exchange of property rights, the exchange of goods (barter) can be realized. This two-dimensional code, which represents "special mention of property rights", can be used as the carrier and payment means of digital currency at the same time, and payment can be completed through "two-dimensional code scanning".

2. Is it MLM?

3. To tell you the truth, this must be fake, don't believe this kind of thing
first of all, blockchain is a kind of chain data structure that connects data blocks in sequence according to the time sequence, and it is a kind of tamper free and forgery free distributed ledger guaranteed by cryptography
secondly, the concept of blockchain is brought out through bitcoin. It is a kind of technology. How can technology be realized? It must be combined with practical applications in life and create practical value before it can be used to make money
so the best way to do something we don't know about is not to touch it.

4. It is an intelligent contract platform based on blockchain technology and an innovative technology. It's worth doing well to understand!

6. Renren blockchain service enables users to quickly build their own
IT infrastructure and blockchain services on an elastic and open cloud platform. Using
baas
can greatly rece the cost of realizing the underlying technology of the blockchain, simplify the construction and operation and maintenance of the blockchain, and meet the personalized needs of users in the face of various instry scenarios, so as to quickly deliver and customize
baas in one stop.

7. Unknown_Error

8. It's probably caused by biter maintenance. Please contact their customer service. They have records over there. They can get them back
a lot of bitcoin was stolen from biter some time ago. I don't think it's safe. I'd better change a trading website

if your problem is solved, please adopt it
if not, please continue to ask
