Ethereum 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>
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.
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:
smart contract is one of the major milestones of the technology roadmap of bit fed project. In order to prepare for the implementation of smart contract on UB, the UB team made some adjustments on April 10, 2018, as follows:
1. The block speed was adjusted from 10 minutes to 1 minute
2. The difficulty adjustment cycle was once for 10 blocks
3. Block reward was adjusted to 1 ubtc
The total amount of ubtc was adjusted from 21 million to 20 million The mature period of reward was 7200 blocksthis adjustment requires users to download the latest version of the wallet to ensure that subsequent use will not be affected

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
then why should I say that lightning bitcoin is a great currency experiment? We compare lightning bitcoin to a free economy with three major stakeholders: developers, miners and holders
so far, no blockchain project can effectively govern the three. Why? The reason is very simple. In an ICO project, the developers, coin holders and even miners are the same group. It's easy to understand. Why should he give the best interests to the ICO holders? This is obviously not in line with human nature. The reason why lightning bitcoin dares to do chain governance is related to the issuing mode of lightning bitcoin. LBTC's "governance on the chain" is another attempt to "decentralize", which is also very eye-catching. Dpos mechanism determines that there are 101 nodes in the network. At the same time, unlike pow, the right of choice is in the hands of the coin holder. These nodes will be elected by the vote of the coin holder. When the node does not act, the user can vote out of the network. According to last week's weekly report, LBTC's block browser has also added this function, which can view the operation of nodes in real time. It also paves the way for LBTC's "chain governance". In the LBTC system, all coin holders can vote to decide whether the project development proposal will go or stay, and all members of the organization can participate in the decision-making and operation of the organization. In addition, the 5000 standard of lockup after the election of the lightning node ensures that the node is both a mine pool and a coin holder. In this way, the relationship among miners, developers and users is well balanced, and the foundation of an autonomous organization is formed.
