If bitcoin represents blockchain version 1.0, it proves to the world that digital currency can be realized. Then Ethereum represents blockchain version 2.0, which lets you know more about the play of blockchain, decentralized applications and smart contracts. In 2018, blockchain will enter the stage of 3.0, application and scenario landing will be the core of blockchain, and blockchain based applications in various instries will spring up, which will be the early dividend period of the last stage of blockchain development. The demand for talents driven by the application of blockchain technology has become increasingly large. Blockchain technical talents have become the new professional talents, which are highly competitive, and also have enviable high salaries

whether to form a meaningful large-scale consensus: one of the outstanding advantages of blockchain is that it can effectively form a large-scale consensus by opening account books and notifying the whole network. At present, there is no need to form a network wide consensus for many projects. Some projects are just for crowdfunding and token issuance. The blockchain consensus of projects is meaningless. Does this model have network effect: network effect means that a project will become more and more valuable with more and more users of the project, because the value of the project is not in the users themselves, but in the connection network between users. Bitcoin is a typical example. The more user nodes there are, the more links between nodes will grow exponentially, and the whole ecosystem of bitcoin will be more valuable

of course, in addition to these points, there are many basic principles to judge the project, such as effective incentive mechanism, strong team, project solving pain points, and so on

3. Go is an open source programming language, which makes it easy to construct simple, reliable and efficient software. If you want to learn this programming language, you should first find a good tutorial. Brother Lian's go language + blockchain training has recently published a new set of go language tutorial, and the teacher's speaking is very good

with the global hot discussion of the concept of "blockchain", the application of blockchain technology has been quietly added to the daily life scenes such as finance, logistics, credit reference, manufacturing and retail. Some experts have shown that the future blockchain will be closely related to people's lives, and the integration of blockchain technology and people's daily life is the general trend

the popularity of the blockchain market has triggered a large number of talents demand based on blockchain technical personnel, and the popularity of blockchain talents is rising at the speed of light. According to the "2018 blockchain high salary list" released by lagou.com, Tencent, Xiaomi, Suning, Jingdong and other domestic enterprise giants have released many high salary blockchain post demands, trying to explore blockchain related technologies and applications. It is also pointed out in the list that the demand for high salary jobs is mainly based on blockchain related technical jobs, among which Suning and Keda have been given the highest monthly salary of 100k

the huge market demand for technical talents will inevitably lead to the explosive emergence and growth of the whole blockchain training market. Most of the training modes can be divided into online training, traditional IT organization training, and offline short-term training camps, which mainly focus on high-end forms. However, in the process of the hot market evolution, there are also a variety of blockchain training chaos: lecturers' qualifications are watered down, and even the most basic names are not disclosed, the syllabus is opaque, and the teaching quality is shrinking, Unreasonable class arrangement and uneven training fees and so on

with the large-scale development of the whole blockchain training market, brother company ecation, together with Yin Cheng, a senior blockchain expert, and his Tsinghua Shuimu Weiming team, has set up a blockchain college. With its professional and powerful team of technical lecturers, detailed and comprehensive curriculum system, and a large number of authentic enterprise blockchain projects, it aims to deepen the blockchain teaching and training field, And train more professional technical talents for enterprises and society<

He has deep experience in project management and R & D, has two AI invention patents, and has practical experience in developing e-money deployed to Microsoft Windows azure. Teaching explanation is in simple language, so that students can apply what they have learned.

4. Blockchain is a concept. Blockchain technology is not only the technology to realize the concept of blockchain, but also the code. Bitcoin is based on the concept of blockchain and developed with blockchain technology.

5. Based on Ethereum development EtherCAT, this is not an application, play a bit interesting, and Netease planet. It is used for traceability. The orange chain that has been snapped up by China enterprise Tongbao blockchain is used for the traceability record of blockchain on the orange.

6. Blockchain technology has been widely sought after since it came out, and is regarded as the leading technology of a new round of instrial revolution., At present, blockchain has gone out of the concept stage and is about to enter the era of blockchain 3.0. But unfortunately, there are still many security loopholes in blockchain technology in this era. Both blockchain enthusiasts and cryptocurrency speculators have heard and witnessed the endless debate about the limited transaction throughput and high fuel cost and low efficiency of blockchain, and deeply felt the bottlenecks and pain points of blockchain technology in these instries, which are greatly related to the inherent deficiencies of blockchain architecture

Ten core technological innovations to jointly build a complete ecol ecosystem.

7. Explain blockchain with scientific language --- blockchain is a permanent and irreversible modified record generated by superimposing encrypted data (blocks) in chronological order. Many financial institutions in the world, including JPMorgan Chase, HSBC, Citibank and New York Mellon bank, have also cooperated with blockchain companies to study the application of blockchain technology in the financial market. The person in charge of the blockchain Technology Laboratory of Shanghai Heshu software said that when there is no trusted third party in blockchain, all transaction data will be stored in a data block, and the transaction information will form a complete chain and be included in the blockchain, which is a more reliable ultimate solution than the trusted third party.

8. I don't know what you want to know, as far as blockchain 3.0 is concerned. At present, there is no accurate concept, or it is not completely determined. Most people think that DAPP technology represented by EOS will open "blockchain 3.0"
DAPP is the abbreviation of decentralized application, which translates into decentralized application, also known as distributed application. Compared with the app we are familiar with, DAPP does not rely on IOS and Android system development, but is put on the blockchain system and combined with smart contract. DAPP is to blockchain just as app is to IOS and Android
generally, different dapps will adopt different underlying blockchain development platforms and consensus mechanisms, or issue their own tokens, or use common tokens based on the same blockchain platform. However, DAPP can not be developed on all blockchains, but must use a public blockchain platform with smart contract function. It allows anyone to build and use distributed applications running through blockchain technology, such as Ethereum and EOS.

The current development stage of blockchain Technology: financial value period, credit value period and governance value period. Among them, blockchain 3.0 and 4.0 are developing rapidly. It is predicted that there will be a wave of great changes in blockchain technology

ecology makes the main chain and the side chain

ecol ecology makes the team deal with the difficulties faced by the side chain. Through data isolation and cross chain audit, the business data confidentiality and security of the side chain can be guaranteed, and the balance between data transparency and business confidentiality can be solved

and support multi side chain, main side chain communication, asset transfer, both integration and division of labor, both security and convenience. The main chain is mainly responsible for security and consensus. The side chain will provide smart contracts, token issuance, asset trading, cross chain interoperability, and the structure of the main and side chains. Through slimming and pruning technology, it can effectively prevent block swelling, garbage accumulation, and shorten synchronization time. To clear the obstacles for the implementation of high concurrency and lightning network

ecol ecol makes it possible to connect different blockchains through side chain technology, which is the key to solve the problem of slow transmission speed and low efficiency in expanding the external structure of blockchain. In short, the side chain is like a channel, connecting different blockchains together to realize the expansion of blockchain. In the long run, ecolink will graally build a high-speed value Internet belonging to the side chain in the case of developing, applying and proposing solutions
