How to calculate the pledge reward on the Ethereum chain
Ethereum energy coin is not MLM
Ethereum is an open source public blockchain platform with smart contract function. Ethereum provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency Ethereum
in 2013, vitalik buterin, 19, first mentioned the idea of Ethereum in a book entitled "Ethereum white paper: next generation intelligent connection and decentralized application platform". Then, in 2014, the algorithm and protocol of Ethernet coin were officially implemented, and $150 million was raised. The system itself was finally completed on July 30, 2015
as the representative of blockchain 2.0, the mainstream currency Ethernet is regarded as the wind vane of crypto digital currency market. However, over the past week, the price of ether currency has continued to fall. On August 14, 2018, the ethereal currency plummeted by 20%, reaching a record low of $257 this year. Compared with this year's peak of $1295, the price of Ethernet currency has shrunk by more than 80%. Affected by this, on August 15, 2018, none of the top ten mainstream currencies in the digital money market was spared, falling across the board, with a number of single day declines exceeding 10%
extended data
Ethereum started planning almost in 2013, and started to implement the project in 2015. Before that, there were many digital currencies imitating bitcoin in the market, and they made various modifications on the basis of bitcoin code. In this way, it is very difficult to develop a new blockchain application, to re deploy a new chain, and then to develop an application on this chain. Using a consensus mechanism of pow alone is a huge maintenance workload. It's like developing an app on a mobile phone and developing the Android system together
after Ethereum comes out, it is equivalent to the underlying operating system of the blockchain. On Ethereum, it is very convenient to develop various dapps without considering the underlying development, and it can also share the computing power and storage of Ethereum. For programmers, the threshold of blockchain development is lowered instantly. The emergence of Ethereum has played a very important role in the development and popularization of blockchain applications. That's why Ethereum is called blockchain 2.0
what is Ethereum:
Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. Blockchain technology is one of them
Ethereum platform can safely run any program users want
advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum
what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application
The design of Ethereum is very flexible and adaptable
Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields
blockchain applications of Ethereum
Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc
Ethereum has achieved more than 100 blockchain applications by many start-ups
Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged
the relationship between Ethereum and blockchain:
Ethereum is a programmable blockchain
Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes
in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency
like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"
issued based on Ethereum public chain should be observed according to the price trend of the platform.
the trust union credit alliance chain is located in the financial public chain, which is oriented to the high-frequency financial application scenarios in the field of credit and assets. It does not use eth, EOS, Neo and other general public chains, but uses the account structure of star network, adopts the lightweight intelligent contract layer, and the whole technical architecture is molarized according to "high aggregation and low coupling", This enables the trust union credit alliance chain to adapt to the requirements of rapid development, rapid implementation and timely response of Internet financial procts.
a total of 22 weeks, divided into five stages,

from the characteristics of the language itself, go is a very efficient language, which highly supports concurrency. Go language itself pays more attention to distributed system, and concurrency processing is relatively good, such as advertising and search, That kind of high concurrency server
go language advantages:
excellent performance, can be directly compiled into machine code, does not rely on other libraries, go is extremely fast. Its performance is similar to Java or C + +
concurrency is supported at the language level, which is the biggest feature of go. It is born to support concurrency, and go is the concurrency supported in gene, which can make full use of multi-core and make it easy to use concurrency
the built-in runtime supports garbage collection, which is one of the features of dynamic language. Although GC is not perfect at present, it is enough to cope with most of the situations we can encounter, especially GC after go1.1
it's easy to learn. The authors of go language all have the gene of C, so go naturally has the gene of C. There are 25 go keywords, but the expressive ability is very strong. It almost supports most of the features you've seen in other languages: inheritance, overloading, object, etc
rich standard libraries, go has built a large number of libraries, especially the network library, which is also my favorite part< As like as two peas, br / > built-in powerful tools, Go language is built with many tools chain, the best should be gofmt tools, automatic formatting code, make team review become so simple, code format is exactly the same, it is very difficult to think differently.
cross platform compilation and fast compilation. Compared with the sluggish compilation speed of Java and C + +, the fast compilation time of go is a major efficiency advantage
disadvantages of go language:
package management: package management of go language is absolutely not perfect. By default, it has no way to make a specific version of the dependency library, nor can it create replicable builds. In contrast, python, node and Ruby all have better package management systems. However, with the right tools, the package management of go language can also perform well
lack of development framework: go language does not have a major framework, such as Ruby's rails framework, Python's Django framework or PHP's laravel. This is a heated discussion in the go language community, because many people think that we should not start with using frameworks. This is true in many cases, but if you just want to build a simple crud API, it's much easier to use Django / djrf, rails laravel, or Phoenix
exception handling: go language can help developers deal with compilation errors by simply returning errors (or call stack) through functions and expected calling codes. Although this method is effective, it is easy to lose the scope of the error, so it is difficult to provide meaningful error information to users. Error package can solve this problem by allowing us to add context and stack trace to return error
another problem is that we may forget to handle errors. Static analysis tools such as errcheck and megacheck can avoid these errors. Although these solutions are very effective, they may not be the right way.
At present, the mining mode can be roughly divided into PPLNs, PPS and PPS +. However, if you want to get a stable income from mining, it is recommended to choose the mining software of PPS mode
when miners are mining, if you want to know how many etheric coins you get, you can use ha Yu miner to see clearly the daily mining income
Harbin miners showed a unified display of revenue for BTC, easy to see, and support for cash withdrawals to Alipay wallet and bitcoin wallet. p>
this should be a new term rising after "Tongzheng economy" last year. Compared with the token economy, the pledge economy actually has a much greater interest relationship with our ordinary investors
so today's DDS distributed storage ecological community editor will share with you what is pledge economy and how is its investment
pledge economy is also a kind of mining in essence, but it is different from what we usually call bitcoin mining and Ethereum mining
bitcoin, lightcoin, Ethereum, BCH and other digital currencies are all based on proof of work (POW). Therefore, under this mechanism, the generation of new currencies is all competitive power, so there are all kinds of mining machines. At present, the most popular mining machine with the highest market share is bitmainland mining machine
when we want to participate in the mining of these digital currencies, we usually go to the market to buy mining machines, and then find our own machine room or entrust the mining machines to large mines for operation. The money that the miner digs every day, excluding electricity and operating expenses, is the net income
"piling" is another mining method. Usually, digital currency based on proof of equity (POS) and proxy proof of equity (dpos) adopts this mining method
in this mining method, the nodes in the blockchain system do not need too much computing power, but only need to pledge a certain number of tokens, which can generate new currency after running for a period of time, and the generated new currency is the income obtained through pledge
this is equivalent to that we can deposit money in the bank and get a certain amount of interest every year
2. What are the currencies that support the pledge economy
when the main network of EOS went online last year, the voting of the main node officially opened the prelude of stacking
it is 2020 that really makes this way hot. Since the beginning of this year, a series of digital currencies have been launched in the form of pledge. On the one hand, in order to recruit nodes, the project side carries out extensive publicity. In addition, the powerful operators are willing to cooperate with the project side as nodes to obtain stable income
as a result, the pledge mining economy is booming both inside and outside the circle
data distributed storage (DDS) is also a pledge mining mode
the DDS application circulates and pays for the charging services of the whole ecosystem app, such as: annual fee of video website, online ecation, online Red live broadcast, games, movies, catering, takeout, social networking, etc
DDS issuing mechanism: no private placement, no node selling, no project party. As you go in, as you go out, as you dig, as you sell. There is no big business. Human risk control and ecological empowerment
1. Total distribution: the total distribution of DDS is 180 million, with a constant total. The issue price is anchored at 0.5usdt
2. Design principle: the DDS team made a statistical analysis on the blockchains of data storage related instries with high return on investment in the world and drew a scatter diagram. The analysis results show that, combined with the user experience that the unit price of issue is easy to measure, the total amount of issue is 180 million
3. Distribution ratio:
5% candy distribution
5% pledge circulation
90% mining
according to the number of miners contribution space size mining, strictly in accordance with the hardware equipment involved in mining quantity, pledge certificate and mining output, token price, three trigonometric function output. In the second year, the annual output will be reced by half, and in the eighth year, the remaining output will be excavated.
advantage: unlimited currency needs three confirmations for a transaction, and each confirmation takes 30 seconds, so the transaction confirmation speed is very fast. It is used in daily and common transactions, which is more practical
at present, the central bank's research on digital currency is still at an early stage, and it only plans to launch digital currency, but it is still far away from issuing digital currency. When the central bank studies digital currency, it may study the existing mainstream digital currencies such as bitcoin, Ruitai, dogcoin, etc.
