Is there any reward for all nodes of blockchain
However, where are the opportunities for these innocent employees? To put it bluntly, some blockchain entrepreneurs are bent on "empty handed White Wolf", and exploit layer upon layer through "deception". Using asymmetric instry information, blockchain, digital currency and other projects are over packaged, giving people a sense of "Hope". This part of the blockchain entrepreneurs' inherent "bad root", to a certain extent, has led to the instry's "sick" development trend
some blockchain entrepreneurs call for embracing the times, changes and the future, emphasizing the charm of decentralized "fairness". But in reality, it is for self-interest, which hurts the interests of job seekers and other related groups, which is a great injustice in itself
The asymmetry of information is not permanent. Blockchain, digital currency and so on are all areas worthy of attention, but they are not the capital that can be used by some entrepreneurs as unlimited squanders all the time. For the job seekers who want to join them, they should polish their eyes, otherwise they may be surprised if they are not carefulAt noon, 31 year old Guo Yang (not his real name) had just finished his morning technical meeting, and then he had seven or eight hours of technical discussion waiting for him. He rarely had time to get out of his work and have a meal with his friends. When he heard the other party say "blockchain technical director's annual salary is 1.5 million", his hand trembled and the bowl almost turned over
Zhang Zuoyi's goal now is to complete the transformation of blockchain technology in other scenarios in the same way. He said that as the team has done more and more, we can see that there are more than 300 online brands, and there are nearly 8000 procts. Just like building blocks, he is building his cooperation relationship on the basis of the cooperation of some brands
Guo Yang is also full of ambition at the moment. At 9 p.m., he finished his shift and had dinner with friends in the company canteen. While talking about the latest progress of the blockchain project, he experienced the ups and downs of the blockchain instry and heard some sad or happy news. On the contrary, he felt that the blockchain technology had more vitality and was worth exploring. Thinking of this, I feel that my ambition has been released by my current work, and I am looking forward to establishing a career that really belongs to blockchain technology
core analysis:
1. Transparency, 2. Openness, 3. Information can not be tampered with, 4. Decentralization,
5. Detailed analysis
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
1. In a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged by cryptography
2. Broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code.
blockchain technology has the following four ways to make money:
1. Hardware and infrastructure. A typical one is mining machinery proction and distribution chain, where you can make money by buying mining machinery and digging
2. The underlying platform of blockchain and common technologies, such as Ethereum and other public chains, and the privacy protocol nucypher, where you can make money by investing in its token, building applications on the chain, and providing services for users
3. Various vertical applications, such as supply chain traceability and Finance Based on blockchain, right confirmation and trading, can be used or invested to make money
Service facilities, such as digital asset exchange and wallet, media procts, etc., you can make money by making your own exchange

extended data:
type of blockchain
1. Public blockchain
refers to: any indivial or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain, Anyone can participate in its consensus process
public blockchain is the earliest and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain, and there is only one corresponding blockchain in the world
2. Consortium block chains: multiple preselected nodes are designated as bookkeepers within a group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process), and other access nodes can participate in the transaction
3. Private blockchain
private blockchain: it only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and only enjoys the write permission of the blockchain. This chain is not very different from other distributed storage schemes
does each node have complete blockchain data? You mean a user node? A user node needs to keep the of the block head of the longest workload proof chain, so it knows the data of all the block heads. It can move forward to know all the data on the block chain, but not all of them are saved. A block header is very small, only 80 bytes, which can be saved completely, because the generation of nodes is very slow. Even with the passage of time, the amount is not too large now.
1. Exchanges. Now there are 220 well-known transactions in the world, and about 2000 unknown ones
2. Mobile mining machine: the original mining machine, which costs money and energy, will be replaced by some online games, small videos and articles
3. Blockchain scenario Trading: the blockchain trading platform can be used not only in financial scenarios, but also in e-commerce trading scenarios, game mining scenarios
