Cooperation between Ethereum and PI

1.

Ethereum is an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency ether (also known as "Ethereum")

The token on the

blockchain is called ether, and the code is eth. It can be traded in many foreign exchange markets of cryptocurrency, and it is also the medium used to pay transaction fees and computing services on Ethereum

the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, with the general meaning of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014. As of February 2018, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin

extended data:

Ethereum platform has no characteristics and value. Like programming languages, it's up to entrepreneurs and developers to decide what to use. However, it is clear that some application types benefit more from the functions of Ethereum than others. Ethereum is especially suitable for those applications that automatically interact directly between points or promote group coordination activities across networks

for example, coordinate the application of point-to-point market, or the automation of complex financial contracts. Bitcoin enables indivials to exchange money without the help of financial institutions, banks or governments. The impact of Ethereum may be more profound

in theory, any complex financial activities or transactions can be automatically and reliably carried out on Ethereum with coding. In addition to financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by Ethereum platform on a large scale

2. Most of the well-known domestic hot money, okex, coin, bitcoin and eth exchanges have existed for a long time

3. Pchainnetwork (PI) is a new type of native multi chain system, which makes it possible for large-scale instrial application of blockchain smart contract. The main technological innovations of pchainnetwork include: the world's first native multi chain supporting EVM, sharding consensus pipeline, smart contract of smart data, cross chain call and transaction
according to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk

warm tips: the above information is for reference only. Before investing, it is recommended that you first understand the risks existing in the project, and understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

6. Pu AI nano displacement technology (Shanghai) Co., Ltd. is invested and established by Physik
instrument (PI) GmbH & Co.KG, a German multinational company. Founded on January 15, 2003, the company is located in Zhangjiang High Tech Park in Pudong, one of the most famous high tech parks in Shanghai
Physik instrument (PI) GmbH & Co.KG has been committed to the R & D and manufacturing of micro and nano positioning technology. After nearly 40 years of development, it has become a leading manufacturer / supplier of global technology in the field of micro and nano positioning, and PI has become the most famous logo in this field

over the years, PI procts have been known for their high quality and innovative technology. While providing the best proct quality, PI provides users with innovative technical services and the best solutions. From precision machining to digital and analog control circuit, from sub nanometer capacitive position sensor to original picma
piezoelectric ceramic actuator, PI has mastered a whole set of key technologies. Its strong technical strength promotes the continuous development of micro nano positioning technology to the forefront, and makes PI a partner of many high-tech enterprises and famous laboratories in the world

pi provides users with different types of piezoelectric nano positioning system and motor micro positioning system solutions, and can provide a variety of OEM procts and customized procts according to user needs. PI's procts include 6-DOF parallel robot, piezoelectric nano positioning table, piezoelectric deflection mirror, pifoc
micro objective locator, and linear and rotary positioning table

today, whether in metrology, micros, life science and technology, or laser technology, precision machining technology; Whether it is semiconctor technology, data storage technology, optoelectronics / optical fiber, astronomy and other fields, PI procts and technologies are more and more widely used, and have won more and more praise.

7. Proforma invoice, send the invoice to the customer for confirmation before issuing the invoice, and realize that it does not have legal effect like the invoice! Generally, it contains bank information proforma invoice

8. The similarities are as follows:
firstly, they all consider the time value of capital
secondly, all the cash flows within the project period are considered
thirdly, it is affected by the length of construction period, the amount of recovery and the size of cash flow
fourthly, when evaluating the feasibility of a single scheme, the conclusions are consistent
when NPV & gt; 0, the present value index & gt; 1, internal rate of return & gt; Capital cost ratio
when NPV & lt; 0, the present value index & lt; 1, internal rate of return & lt; Capital cost ratio
when NPV = 0, NPV index = 1, IRR = capital cost rate< The differences are as follows:
net present value (NPV): absolute index, which is used to evaluate the benefit of investment. It is affected by the set discount rate and does not reflect the return rate of the project investment scheme itself
present value index: relative index, which measures the efficiency of investment, is affected by the set discount rate, and does not reflect the return rate of the project investment scheme itself
internal rate of return: a relative indicator, which measures the efficiency of investment, is not affected by the set discount rate, and reflects the rate of return of the project investment scheme itself.
