Blockchain project deployment
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<
Yin Cheng, a senior blockchain technology expert, graated from Tsinghua University, is the dean of brother Lian blockchain college. He once served as Google Algorithm Engineer, the world's most valuable expert in the field of Microsoft blockchain, and the gold medal lecturer of Microsoft tech.ed conference. Proficient in C / C + +, python, go language, sicikit learn and tensorflow. With 15 years of programming experience and 5 years of teaching experience, senior software architect, Intel Software Technology expert, famous technology expert, with many years of working experience in the world's top it company Microsoft Google. He has many years of experience in software programming and lecturing, and has developed many procts in human-computer interaction, ecation, information security, advertising and blockchain system. 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
the first stage: blockchain instry and go programming for 5 weeks
the second stage: cryptography and consensus algorithm for 2 weeks
the third stage: Ethereum source code analysis and development for 3 weeks
the fourth stage: Super ledger and node.js for 2 weeks
the fifth stage: bitcoin & EOS for 4 weeks
the sixth stage: comprehensive actual combat of the project
Sharing area network:
the application scope of blockchain technology is still very wide. Based on the characteristics of decentralization, distrust, collective maintenance and reliable database, its application in the financial instry is the first step
blockchain is the underlying technology of bitcoin, and the application and development of blockchain in digital currency is mature
like the block chain based trading system development scheme provided by Yingtang Zhongchuang, the developed software system has great safety factor and transparency
according to Xiao Wang, the concept of blockchain as a service (baas) is mainly proposed by Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service combined with blockchain technology. For example, Microsoft's azure cloud computing platform and IBM's bluemix garage cloud platform all provide blockchain as a service baas
blockchain as a service (baas) is a space created by enterprises such as Microsoft and IBM from their own cloud service network to run a blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of baas nodes is to quickly establish the development environment they need, and provide a series of operation services based on blockchain, such as search query, transaction submission, data analysis, etc. these services can be centralized or decentralized to help developers verify their concepts and models faster. The service of baas node is reflected in: stronger tool, easy to create, deploy, run and monitor blockchain..
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
if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"
that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved
most of the existing public chain projects in the market are difficult to put into use on a large scale
Hello, thank you
How can enterprises establish their own blockchain
with the popularity of various currency transactions, the development of the exchange instry has been promoted. As Xiao, who wants to cross instry, how to establish a blockchain exchange development company? Chain soft network summarizes the following points for you
3. Working with banks or payment processors
you need to work with banks or payment providers to process payments in legal tender. You can choose a trustworthy bank with lots of online facilities
4. Create liquidity in your exchange
any exchange needs liquidity to operate successfully. Customers are hesitant to place orders or even deposit money unless they see the full order and transaction activity. New transactions will naturally encounter liquidity problems
5. Ensure high-level security of trading and customer data
any exchange development company needs first-class security to ensure that the funds of exchange operators and traders are safe. This should also apply to your customers' private data, including their KYC details and bank account information. Over the years, the unnoticed GOx vulnerability resulted in the theft of nearly 1% of the total number of bitcoins in circulation at that time. According to chain soft network, between 2009 and 2019, one third of all bitcoin exchanges were hacked. Therefore, security must be the first priority in your transaction
Finally, customer support is another important part of a successful exchange. Staff are required to approve KYC requests, answer customer complaints, process deposits and withdraw legal tender, etc. A fast customer support mechanism ensures that your customers start trading from the date of signing and generate revenue for your exchangeI hope it can help you to solve the related problems. For more details, please feel free to consult and discuss< br />
In the bear market of blockchain, how to find the real valuable blockchain projects? Xiaobian explains from the following aspects:
1. Use the blockchain security technology testing center to see if it is MLM coin or air coin
no matter how advanced the concept is and how exaggerated the slogan is, the essence of any project still depends on technology. Blockchain projects without technology are just like the emperor's new clothes, We need a mirror that reflects the emperor's new clothes - blockchain security technology testing center
As one of the important initiators of blockchain security technology testing center, Tianhe Guoyun, the provider of ulord public chain technology, provides code audit function, which is a sharp tool for blockchain security technology testing center to identify blockchain projects. Code audit is to build a knowledge base of block chain code automatic audit with the help of machine learning and artificial intelligence. It can improve the efficiency of code audit and solve the security problem of intelligent contract. Through the quality evaluation of blockchain projects, exchanges, wallets and smart contract codes, blockchain code audit can prevent digital asset security accidents, provide code revision measures, security protection deployment and other services. It is reported that in addition to automatic audit, Tianhe cloud blockchain code audit can also customize expert team projects for all-round audit to help investors identify "fake projects" to a greater extent2. Look at the team of blockchain project
the blockchain field can be regarded as a comprehensive field, involving cryptography, mathematics, economics, even social management and other disciplines. We have a reliable team. As I mentioned above, the ulord project brings together a large number of high-level R & D and operation personnel
3. It is not only the concept of stir frying, but also the application of it
there are many startups in the field of blockchain. If you want to become a few widely recognized high-quality projects, it is not feasible to just speculate on a set of concepts or theories. Only the projects with the ability of making blood and doing things on the ground are good projects
at present, DAPP ushare, an application based on ulord public chain, has been officially tested on October 15. Ushare Youxiang is the first decentralized experience value sharing platform in the world, and the first DAPP based on ulord public chain. Through the decentralized consensus mechanism, we can build an open, fair and just content evaluation system, encourage high-quality experience procers and experience sharing disseminators, and let the value of high-quality experience flow
there are nearly 100 teams and projects carrying out negotiation and cooperation with ulord public chain
4. Communities have autonomy attributes
whether communities have Dao (distributed autonomous organization) attributes, which is naturally suitable for blockchain,
about community governance. Whether it's the operation mode of the community or the organizational form of the developer community, it's actually a process from quantitative change to qualitative change. We have realized the importance of community
ulord adopts the community autonomy mode of "everyone can participate and contribute to the ecology"
we will have some new community governance modes, including the cooperation of some developers and the cooperation mode of large-scale open source community, which will be born and flourish
The incentive system mainly includes three aspects: first, participation in bookkeeping; Second, the contribution of network resources; Third, participate in community construction. As mentioned above, in the accounting part of our whole budget system, the pow + POS part accounts for 60%, the contribution level of participating in open source community code accounts for 10%, and the remaining 10% is used as an incentive for community operation. Therefore, we hope that more people can participate in the construction and promotion of ulord. We hope to build a platform, but the dividends obtained by this platform should be shared with everyone in the largest range, which is essentially different from Internet proctsthis kind of stacking design of eth 2.0 is compatible with its fragmentation chain structure. By setting the fixed mortgage number of 32eth compulsorily, the number of nodes in the whole network is relatively large, and the head node with huge mortgage number will not have monopoly accounting control right in a fragmentation chain, Therefore, the degree of decentralization of eth 2.0 mining will be improved to a certain extent
the second difference: principal and income are not one kind of currency, which can not be traded in the early stage
except for ontology, vechain and other al currency structure design projects, generally speaking, stacking mining is "lock what currency, earn what currency", but eth 2.0 locks eth token on the main chain of pow, and the income released is Beth token on the beacon chain. They are essentially two kinds of currency. Because the two chains will not be interconnected soon, the transaction prices of Eth and Beth in the open market will not be exactly the same
at stage 0, which is expected to go online next year, ETH 2.0 will not have the trading function. Even if the verifier (node) withdraws from staging, the principal and income can not be transferred out of the account. Therefore, all the principal and income of the early participating nodes are almost locked. We can only wait for the further development of eth 2.0 to graally realize the account trading function
the third difference: in the early stage, there was no decentralized entrusted mining
the function of "entrustment" can separate the token from the block right carried by the token, and the token holder can entrust the block right to trusted nodes to participate in consensus and win awards on behalf of them, which is also the reason why stacking is widely known by the public and is becoming popular. However, in the first two phases of eth2.0 (phase 0 and phase 1), there is no decentralized entrusted mining, which means that the coin holder can only set up its own node to run, or hand over the coin to the centralized mine pool to mine on behalf of it. However, agent mining is equivalent to transferring the coin to someone else for trusteeship, which has the security risk of capital
secondly, we need to understand the participation conditions of Ethereum staging
the participation threshold of Ethereum staging is not very high. In terms of hardware, the performance of home computer can run a node. Ethereum hopes to encourage more money holders to participate through low threshold, so as to achieve the goal of decentralization as much as possible
because the coin holder is not a professional node operator, it is generally unable to guarantee the 24-hour operation of the node. Therefore, in the design of the economic model, the penalty of Ethereum stacking for the node offline is very small, about 1% for three consecutive days, but the longer the offline time is, the greater the penalty will be, and 50% for 21 days offline
for the participants, 24-hour operation of the node can ensure the maximum revenue. At the same time, it is also necessary to do a good job in node version upgrade, prevention of "double flowers", fault monitoring and disaster prevention. At that time, some node operators will launch professional node operation services
after understanding the above information, let's take a look at the revenue analysis of Ethereum stacking
the annual SEO rate of eth 2.0 changes dynamically with the whole network pledge rate. According to the published rules, the relationship between the annual SEO rate and the whole network pledge rate is 0.5 power. The higher the pledge rate of the whole network, the higher the annual additional issue rate, and the lower the annual return rate of a single node. When the whole network pledge is 10%, the annual yield of the node is 5.72%.
most digital cryptocurrencies claim to be a third-party payment instrument. Although they are also feasible in theory, the actual situation is just the opposite. The payment using digital cryptocurrency is very little, and the most used one is still bitcoin, and the others basically do not exist. If it exists, it's just hyping this kind of currency. Now, the application-oriented digital currency basically does not mention payment. For example, Ruitai coin refers to asset mortgage, and Weimeng coin refers to service wechat business.
