Blockchain value Internet Course

1.

Because the design of blockchain is a kind of protection measure, such as distributed computing system with high fault tolerance. Blockchain makes hybrid consistency possible. This makes blockchain suitable for recording events, titles, medical records and other activities that need to include data, identity management, transaction process management and provenance management. Blockchain has great potential for financial disintermediation and has great influence on guiding Global trade

extended data :

1. Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

2. Blockchain is an important concept of bitcoin, which is essentially a disintermediated database and the underlying technology 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

3. Blockchain - the original blockchain is a kind of decentralized database, which contains a list called blocks, with continuously growing and orderly records. Each block contains a time stamp and a link with the previous block. The block chain is designed so that the data can not be tampered with. Once recorded, the data in a block will be irreversible

What is

...

blockchain? Maybe few people can really answer this question. It is precisely because of the inherent mystery of "blockchain", that many people are eager to pay for knowledge in order to get on the train to the "future"

therefore, all kinds of blockchain training are also very popular, and all kinds of information, such as "scanning code, entering the group to listen to lectures", are filled with the circle of friends, so it is difficult to distinguish the good from the bad. The training costs are even more uneven: 100 yuan, 300 yuan, 7000 yuan or even nearly 100000 yuan...

blockchain training is too hot

I often make up my identity on the dating materials, such as import lighting wholesalers, urban landscape designers, boutique tobacco hotel owners and agricultural loan salesmen. Now, I have finally become an expert in blockchain training courses

and it is reported that a blockchain recruitment advertisement in Beijing recently blew up the circle of friends, requiring candidates to have in-depth research on blockchain technology and cryptography, giving an annual salary of not less than 5 million yuan, and not capped

"this is really the current situation of blockchain talent recruitment. But even so, we can't find people, because it's hard to find qualified people. " Lu Sheng, head hunter of Liepin platform, said

Song Mofei, senior researcher of Suning Institute of finance, said: "in terms of development experience, the rise of domestic blockchain instry has been concentrated in the last two or three years, and few people have long-term blockchain development experience in the talent market." He believes that excessive salary will inevitably attract some speculators, but the increase of salary does not bring about the increase of the application threshold, and even some recruiters only know a little about blockchain technology, which also poses new challenges for the recruitment of blockchain talents

according to Shan Yi, chief data officer of liepin.com, the core of blockchain is the change of social relations and business model based on Internet distributed trust system, which is characterized by decentralization“ There are still many uncertainties in the future development of block chain. There are obvious bubbles at present, and many block chain projects are not reliable. He said

3. Block chain + content refers to the application scenario of content instry that is activated by block chain technology, while Internet plus content refers to the concept of expanding content domain based on Internet. The difference between the two is that the former relies on the blockchain for content valuation, which can make the content valuable. The latter only uses the characteristics of the Internet to spread the content, and does not support content payment. Speaking of this, we have to give Amway a blockchain project named Aqua oxyhydrogen, which belongs to the content public chain. I hope it can help you.

4. 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.

5. In my opinion, the biggest difference between traditional blockchain projects and blockchain content projects is that the latter uses blockchain technology and combines content output mode to help content procers protect right, expand publicity and explore content value. For example, aqua hydrogen oxygen content public chain project can help content procers expand content value in their procts. The subject can download the DAPP of aqua project for learning. I hope it works for you.
