Blockchain and hairy crab

1. In essence, blockchain is a decentralized ledger system, which has the characteristics of decentralization, openness, non tampering information and programmability. It can be used as the underlying storage and transmission protocol of value Internet. Blockchain is expected to lead us from personal trust and institutional trust to the era of machine trust. Consensus mechanism is the core of regional chain construction. digital currency is just the beginning. Blockchain can change more, reshape the world's trust system, and solve many problems of high trust cost in the past
there is a core difference between blockchain and Internet: the value of underlying protocols and upper applications of blockchain and Internet are completely reversed. It mainly comes from the two core features of blockchain:

the first feature is that zero knowledge proof changes the ownership of data. In other words, the user's personal data on the blockchain belongs to the user and does not need to be provided to the application and stored on the central server. Then the core support "data" behind the market value of Internet application layer services, such as bat, will lose its original value in the field of blockchain
another feature is the economic incentive model brought by token, which gives high value to the underlying protocol. In the Internet era, no one pays for HTTP protocol, no one pays for sending and receiving email, and no one pays for Google's search service.

2. 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".

3. If you want to ask what's the most popular in 2018, I believe you will say it's blockchain

since last year, a variety of digital currencies have emerged in an endless stream, and blockchain has also been on fire

many people are connected with blockchain as soon as they mention currency speculation; As soon as you hear that an enterprise is doing a blockchain, you will immediately ask if you want to issue money

it seems that blockchain is equivalent to digital currency, and the purpose of studying blockchain is to speculate in currency< br />


1

when you are new to blockchain or digital currency, it is reasonable to equate blockchain with currency speculation

after all, if it wasn't for the growing popularity of bitcoin, no one might have paid attention to blockchain technology so far. If it wasn't for more and more people investing in bitcoin, no institution would have issued a variety of other digital currencies

however, after in-depth understanding of blockchain and digital currency, we still think that blockchain is money speculation, so our understanding is really a bit biased

blockchain is the underlying technology of bitcoin. No matter bitcoin, Ethereum, lightcoin or other various tokens, they are all applications based on blockchain technology

but this does not mean that the blockchain can only be used to issue money, just like fish is raised in the water, but it can not be said that fish is water, and hairy crabs and crayfish can grow in the water

in addition to the various tokens we see at present, blockchain has a very broad application prospect

2

so what is a blockchain

to put it clearly, blockchain is: "blockchain is a kind of technical mole or encryption algorithm that is both basic application and top-level design. It breaks the barrier that an information is only saved by one central server or multiple services in the past, and copies the same information to more places at the same time, such as 1 million servers. Only when more than half of the stored information has been tampered with can chaos be caused. "

in a word, understand the relationship between bitcoin and blockchain:

blockchain is a technical concept born from bitcoin encryption technology

bitcoin is a kind of digital virtual currency, followed by the payment currency as a contribution to storage computing power

if you want to store the same information in countless servers, who will store it for free? There has to be a reward. Bitcoin is a reward for accepting free storage. This reward is a virtual thing called bitcoin.

4.

Blockchain and artificial intelligence are the next era

There is a good combination between the two

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

artificial intelligence, abbreviated as AI. It is a new technical science to research and develop the theory, method, technology and application system for simulating, extending and expanding human intelligence

Artificial intelligence is a branch of computer science, which attempts to understand the essence of intelligence and proce a new intelligent machine that can respond in a way similar to human intelligence. The research in this field includes robot, language recognition, image recognition, natural language processing and expert system. Since the birth of artificial intelligence, its theory and technology have become increasingly mature, and its application fields have also been expanding. It can be imagined that the scientific and technological procts brought by artificial intelligence in the future will be the "container" of human intelligence. Artificial intelligence can simulate the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can think like human and may surpass human intelligence

At present, blockchain technology can be divided into three versions

At present, in the first three versions, there are some problems, such as the lack of decentralization, low scalability, the mismatch between the incentive of the blocker and the best profit of the whole network, and the network always runs at the maximum capacity, such as bitcoin and Ethereum, which affect the efficiency

Velas combines the two to develop a public chain that can learn and improve itself

Velas enhances its consensus algorithm through artificial intelligence (AI) optimized neural network, and concts self-learning and self optimized public chain, aiming at improving the security, interoperability and high scalability of transfer process and intelligent contract. Velas adopts the dpos consensus enhanced by AI, which completely realizes decentralization without recing the security and transaction speed

technically, Velas has integrated functions and services such as cross chain payment, multi signature wallet supporting multi currency, anonymous transfer, etc. Its Ecosystem focuses on all application scenarios covering transaction and payment, such as exchanges, multi signature wallets, merchant platforms, etc. after AI is fully connected to the system, the transfer fee can be completely exempted

and complete decentralization through AI enhanced dpos (aidpos) & gt; AI chooses who to mortgage the token according to the needs of blockchain & gt; Velas only blocks when needed & lt; Between every 1 second and every 2 minutes & gt& gt; Scalability (up to 30000 TPS) & gt; Block procers are selected by artificial intuition< br />

and then apply for Yudian terminal security system
and then use the Tencent Yudian to kill the virus

6. At present, there are many such teams, and the blockchain is suitable for all walks of life, but before the early cooperation, we must pay attention to the team strength and effect. The baker chain blockchain that we understand has a good evaluation in the instry, good reputation and good performance in all aspects. The evaluation of the instry is quite high.

7. no, it isn't. Blockchain is the underlying technology of bitcoin, and bitcoin is the first generation application of blockchain. What blockchain solves is the trust reconstruction on the chain (including the Internet), which will greatly improve the efficiency and trust value of the whole process. At present, the application of blockchain is still in a very early stage and has not been implemented in a large area. It is mainly applied in the fields of finance, government affairs, medical care, art and so on. Its future, like the current Internet, will penetrate into all areas of social life, helping food and art traceability, recing the risks of money laundering and fraud in the financial system, and improving logistics efficiency.

8. All the contents are recorded on the chain. Recently, it seems that there is a ZIL exchange, with about 20% arbitrage space. The arena also has a very good profit margin
