Blockchain weekly
2017 is the first year of blockchain outbreak, and 2018 will be the first year of blockchain landing
what changes has blockchain brought to the world from 1.0 to 3.0
the development of blockchain can be divided into three stages: point-to-point transaction, smart contract and pan blockchain application Ecology (token economy)
blockchain 1.0 era: the era of digital currency return rate is the king, Digital currency trading is the most important form for people to participate in the blockchain. At this stage, few people really pay attention to the application value of digital currency, let alone the practical value of blockchain technology behind it. People's focus is on the rate of return of digital currency, which is equivalent to buying stocks on another disk. However, this "stock" is more active, and the rate of return is amazing. Of course, it is also full of sorrow
blockchain 2.0 era: smart contract provides infrastructure support for upper layer application development
"smart contract" era, which is the real programmable blockchain, usually represented by "Ethereum", supports Turing's complete scripting language at this stage, It provides the necessary infrastructure for developers to develop any application on the basis of their set "operating system", and realizes the application landing of virtual world. The biggest contribution of blockchain 2.0 is to completely subvert the traditional concepts of currency and payment through smart contracts. In the era of blockchain 2.0, blockchain has formed a trust foundation based on the characteristics of traceability and non tampering, which provides a trusted execution environment for smart contracts and makes it possible for contracts to be automated and intelligent. The biggest difference between the smart contract and the traditional contract is that it is not restricted by the law of the real society. For the contract subject to automatically execute the agreement after triggering the contract terms, However, the arbitration platform no longer judges the execution result in the smart contract, but undertakes the responsibility of execution
blockchain 3.0: the subversion of business lies in the transformation of proction relations
we are now at the junction of 2.0 era and 3.0 era, which can be regarded as an ideal vision for the future virtual digital currency economy, In blockchain 3.0, people can really realize the asset on the chain, build a variety of applications in a large underlying framework, build a platform with no trust cost, super trading ability and extremely low risk, which can be used to realize the increasingly automated distribution of physical resources and human assets around the world, and promote large-scale cooperation in science, health, ecation and other fields
blockchain 2.0 constructs digital identity, smart contract and other infrastructure. On this basis, it hides the complexity of underlying technology, and application developers can focus more on application logic and business logic. That is to say, we have entered the era of blockchain 3.0, which is marked by the emergence of token. Token is the value transmission carrier on the blockchain network, which can also be understood as token or token
the greatest effect of token on human society lies in its transformation of proction relations. Joint stock companies will be replaced, and every actual participant will become the owner of proction capital. This new type of proction relations inspires every participant to contribute his proctivity continuously, which is a great liberation of proctivity. If this kind of business activity is mapped into the inflation of real society, as long as the former outperforms the latter, every token holder will gain over time
it's too early to talk about blockchain 3.0. Although blockchain has gone out of the conceptual stage, the current situation of blockchain technology development is that the underlying technology is not mature enough and the application scenarios are limited. On the one hand, consensus algorithm and other core technologies of blockchain still have room for optimization and improvement; On the other hand, the processing efficiency of blockchain is difficult to meet the requirements of some high-frequency application environments in reality. Moreover, the current mainstream blockchain technology platforms are all originated from abroad. Domestic blockchain technology service providers should patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the development of global blockchain technology, which still needs a certain period of time
the final goal of the competition is to really concentrate on the research of technology and the development of practical application enterprises! According to my observation, among the various applications based on Ethereum, SEC social e-commerce chain has a great chance of landing, which is likely to become a killer application. In the official account of SECblock, weekly weekly reports show that the team is working hard. p>
in fact, as a community, it can let people with the same hobbies get together, and then let the thinking collide. Blockchain technology is a new technology, so it needs more communication and discussion. In order to exchange some experience in the exchange, get better ideas for practice. However, there are few blockchain communities, and the supervision of blockchain is also uncertain
in fact, the most important thing is not to mention, the most important thing of blockchain technology is to continuously carry out experimental application, so as to get more experience, so that blockchain applications can be implemented. Only when more blockchain applications are implemented will blockchain technology get more attention.
take the exchange as an example, if you want to find an exchange, you no longer need to find someone to register a link, or search the exchange through the search terminal, you just need to open the exchange column in imapp and click download to download it with one click, such as coin security, okex, fcoin, fire coin, BIGone and so on
in addition, imapp also provides users with tools and software commonly used in the coin circle, collecting reliable instry information, including blockchain protocols, guessing and other applications, as well as various popular blockchain applications. The detailed pictures of almost every software in imapp are screenshots of the page after the software is opened. What you see is what you get. And all the apps and imapp will be installed and tested in person before they are put on the shelves to confirm their safety and availability.
Coin call
money? This is the meaning of Zhihu who wants to be a coin circle or blockchain
coin is not a game, but a vertical community platform tailored for the coin circle. Through the incentive of token key, users can get the corresponding return. Coin is not only the information distribution center of token investors, but also the communication platform between "coin officials" and "coin friends"
token key encourages
token key introces blockchain token key, which represents the right to use the ecological functions of the platform and weekly newspaper. Through token key to encourage users' positive behavior, users will get corresponding rewards for their efforts on the platform. The incentive behavior of the current version of key is as follows
< UL >publish excellent content: that is to reward excellent posts to match "content contribution" and "income acquisition", so as to realize incentive compatibility
discover excellent content: that is to say, to reward wise eyes and discerning pearls. Excellent posts are selected and determined by users' likes, and users who like also get the key award
managing excellent theme plate: that is to reward community administrators. Different theme plates are "shops" operated by different community management groups. Excellent theme plates will surely get higher advertising value, and the management group will also get better advertising revenue share
the purpose of the follow-up version of key:
pay to see ads: that is, users earn money by watching ads, and 75% of the advertising revenue of the platform will be distributed to each ad viewer on average
paid private group: paid private group is a way to realize the knowledge and influence of opinion leaders, and the payment of private group is realized through key
paid Q & A activities: users can launch real-time Q & A activities on the coin platform, and the payment of Q & A activities is realized through key
in addition, there are paid private messages, access to privileges, rewards, the right to use the surrounding ecological environment, users as stakeholders and so on
The distribution oftoken key
the total amount of key is 100 billion and will never be issued. The allocation of key is composed of four parts: incentive pool, promotion and operation pool, money fund and team option
incentive pool: accounting for 45% of the total, the number is 45 billion key, which is used to motivate users to publish excellent content and discover excellent content
promotion operation pool: 25% of the total, with 25 billion keys, which is used to develop new users, absorb and motivate opinion leaders, and improve the activity of the platform
the fund accounts for 25% of the total amount, with 25 billion keys. The fund is a non-profit organization, holding keys to ensure that the technology development of the fund can be completed
team options: 5% of the total, 5 billion keys, as options granted to the development and operation team of Yuanhu
incentive mechanism of token key. The key Award for real name registration is released in phases for two years, with an average release every day. Users will automatically receive the money when they log in to the app for the first time every day
Invitation reward: users who invite friends to register and complete real name authentication can get the right to receive the invitation reward key, and the rules for receiving the invitation reward key are the same as those for receiving the real name reward
content reward: after publishing high-quality articles or comments, you can get high-quality content reward key
praise reward: users who have locked key can get praise reward for good articles. The more users lock key, the earlier they like, the more rewards they get
coin lock reward: users who lock key on the platform are rewarded according to a certain period, that is, users can get more keys by locking key
the necessary conditions for praising are as follows: there is energy
for praising and trampling, with a maximum of 100 points, which will automatically recover to 100 points the next day after consumption
every time you like or step on it consumes 10 points of energy
when the energy is less than 10 points, the revenue of the article will not be affected by the praise and trample, and there is no key reward for the praise
energy is equivalent to the 10 bullets distributed by the platform to users every day. You can use these 10 bullets to find good articles and praise them to get profits. There are only 10 bullets, so you need to cherish them; Of course, if the allocated 10 rounds of bullets are useless, they will be wasted and will not be accumulated
like rules
like: we encourage users to find high-quality content and like it. Each time you like it, you need to consume 10 points of energy, not key. If you don't like / step on the weight or lack of energy, you won't increase the content revenue, and you won't get the revenue
like / step on weight: the key locked by the user + the key to be received by the real name = the weight of each like or step on. The more the key locked by the user, the greater the relative weight
praise reward: 50% of the article revenue will be awarded to the author, and the other 50% will be awarded to the users who like the article. In order to reward high-quality content discoverers, the earlier they like, the more they get, while the later they like, the less they get. Seven days after the article is published, the system will settle the award according to the rules. After the settlement of the article, praise / trample will no longer affect the income
trample: users are encouraged to trample on spam articles and irrigation comments to improve the quality of the community. Trampled articles will rece the revenue and popular ranking scores, and each trample consumes 10 points of energy, not key. At present, you won't get a key reward by clicking on it
explanation of coin phenomenon
after understanding the above rules of coin game, it is easier to explain all kinds of coin phenomena
there are hundreds of likes in the moment when big V's articles are published, because the consensus of big V's articles is basically formed, and the revenue is high. Users can divide up 50% of the relatively high revenue when they like big V's articles, and the earlier they like, the higher the revenue, so there is robot like
this phenomenon deviates from the original intention of "good article has good reward& quot;， The same article big V issued and ordinary users issued income is very different, how to really do "good article has good reward& quot; We need to think deeply
a big V likes dozens or even hundreds of yuan, while an ordinary user likes a few cents / a few yuan, because the revenue of likes is related to the weight of likes, and locking the key can increase the weight of likes. Big V usually locks millions of keys, so the revenue of likes is higher
so if you have a key in your wallet or trading platform, you can withdraw money to the app and lock it. You can increase the weight of like to increase the revenue of like
users who register with their real names will benefit from liking articles, because the key of real name registration reward (to be received) is calculated in the weight of liking, and the key of invitation reward is not calculated in the weight of liking
like consumes energy, 100 points of energy every day, 10 points of energy every time. After energy consumption, there will be no profit if you like again
the reason why I think this project is reliable is mainly from the following aspects:
1. What problems have been solved by using blockchain technology in the project: what Zhidou ecation chain should solve is the problem of untrue, opaque and asymmetric data in online ecation instry and rampant piracy in the instry. To solve this problem, can we not use blockchain technology? At least at present, there is no good solution. Take Tencent Ali as an example, they are also using blockchain technology to solve similar problems, which proves that blockchain technology has advantages in solving the problem of piracy distribution; In fact, many fake projects in the market are crowdfunding and issuing tokens under the banner of blockchain, but the problems that need to be solved can not use blockchain technology at all
2. What needs of users have been solved by the project: solving the problem of piracy distribution, ensuring the interests of creators, and calling for transparent and open data to ensure authenticity, which has always been the appeal of online ecation practitioners (whether lecturers or students). The pain point is still very painful. If blockchain technology can be used to solve these problems, Zhidou ecation chain will benefit the instry
3. Team qualifications: according to the white paper, although the qualifications and background of the team related personnel are not very excellent, they have many years of working experience in ecation and technology. It's understandable that these people work together to do this, and they don't arrange several titles to fool people like many fake projects, Many contacts show that the technical strength is also resistant to manufacturing, which seems to be quite reassuring
4. Project planning: according to the project planning shown in the white paper, the schele is reasonable. Zhidou ecation chain is indeed promoting the progress of the project according to this time. This is also the most reassuring point for me. If the project is not promoted according to the set time, the project will be suspended
5. Project community and community construction: to be honest, I bought more than a dozen kinds of money and entered hundreds of blockchain project communities, big and small. The community of Zhidou ecation chain is the cleanest I have ever seen. The whole community environment is well maintained. There are fixed blockchain instry information push every day, and weekly project newspaper push every Monday, which is very formal, Unlike many social groups, spam advertising information is flying all over the world, and then there will be bickering and quarreling, which makes people very upset; The most important thing is to know the progress of TV. Every week, we can see a lot of teachers, including some instry celebrities. So it seems that community operation is really doing things. More and more teachers joining in is the most important thing for the project, as well as for US investors. After all, the lecturer is the touchstone for US investors
finally, let's make a summary: at present, the reliability coefficient of the whole project is still very high, and the community is really promoting development. Of course, it's hard to say what the final trend is. Since I choose to hold, I will continue to choose trust. I hope that the team members will live up to my expectations
welcome to the questioner and the people who see this answer. Leave more messages and exchange with me. I also hope to see more people's opinions to correct the audience.
It's said that the currency circle has been going on for one day and the stock market has been going on for one year. Although it's a bit exaggerated, it's not unreasonable. In recent days, bitcoin has gone up sharply, but it has come down slightly today. It's estimated that no one can match the speed of the bull bear conversion in the currency circle. However, among many virtual currencies, how can we find high-quality projects? Xiaobian thinks that the bull market is not surprising. The key point is that the bear market still insists on giving weekly reports, at least for the projects with reliable teams. Today Xiaobian still brings you weekly reports of some high-quality projects. The following is the latest weekly project progress report (April 9-April 15, 2018) released by ubtc team. The specific information is as follows:
pre upgrade of Ub smart contract:

community release:
1. The last snapshot of issuing ubtc to Eth and LTC communities was completed on April 11, and the qualified addresses were released on May 2. Please refer to UB website for details www.ub.com The announcement in the news section on March 18
about ubtc:
unitedbitcoin, referred to as UB, code ubtc. UB is not only an upgraded version of bitcoin, but also a leading global blockchain ecosystem. UB is headed by Jeff garzik, a veteran of bitcoin, a core developer of bitcoin and a leader in the blockchain field
UB 100% inherits bitcoin's blockchain and upgrades and optimizes it. The upgrade and optimization of Ub include expanding the block size to 8MB, supporting segwit isolation witness, adding smart contract and lightning network, etc
UB is committed to bringing the inactive bitcoin credit into full play. Finally, based on these credits, we can issue stable currency anchored by legal currency, which can be used in a wide, fast, efficient and intelligent business society
at present, UB team has developed anybit mobile wallet app (anybit is a decentralized multi currency wallet APP), core, core QT and electrum wallet (electrum is a lightweight wallet supporting multi signature), and released a complete blockchain browser
more than 18 trading platforms around the world support ubtc trading
at present, there are about 8000 community banks in the United States where community banks are developed, covering 43000 regions. Because they absorb deposits from local households and enterprises, and provide financial services to local households, enterprises (especially small and medium-sized enterprises) and farmers, the operating performance of American community banks has been relatively good for a long time<
the community bank, which has just sprung up in China in recent years, is not only a natural measure to alleviate the loan difficulty of small enterprises and indivial businesses, but also a necessary measure to improve the financial ecology and macro-control.
