POC blockchain
POC is the abbreviation of proof of concept, which means to provide evidence for opinions. It is a set of suggested electronic models, which can be used to demonstrate the design of teams and customers, and allow to evaluate and confirm the conceptual design scheme. The evaluation of POC may cause the adjustment of specifications and design
function:
the commitment of design and the opinions recognized by all will be recorded in the design adjustment document for future reference. In this way, POC continues to develop. If you need help completing these tasks, you can find assistance resources at Queensland University

evaluation and verification of POC
the process of evaluation and verification is to seek feedback from risk takers through POC and filing design documents. Through POC evaluation, risk takers may put forward requirements for adjusting specifications and design
sometimes, e to design defects or inappropriate places, the design team may have to go back to the drawing board. Customers may decide to stop designing or look for other teams because the design does not pay enough attention to the needs of customers and users, or because of the instability of customer needs
sometimes the change is caused by the customer organization or project decision-maker. Generally, at the end of the evaluation and verification process, the design commitment and the opinions accepted by all will be recorded in the design documents
this is often an important milestone in the life cycle of proct development. After the evaluation and verification, POC can continue to develop
first, ask the respondents how many people have played this pocc
Second, all the projects are fake at the beginning. believe me. Only in the process of doing it successfully, it's true
Third, bitcoin is successful, with a market size of $1 trillion today. If it fails, it is a liar
Fourth, in addition to the mainstream digital currency, the risk is smaller (not without risk), similar to bitcoin, TEDA currency, ether currency, etc. Other small-scale counterfeit currencies are highly risky. How to determine the scale of a digital currency, or the market value, and recommend a software (non trumpet)< No need to think about supervision. There is no guarantee. It all depends on your control and understanding of the project. The brave starve the timid< 6. To judge whether a project is safe or not, it is necessary to have an in-depth understanding and communicate with the team. You need to know what the team wants to do, whether it's running for money or really want to do something< How to judge the quality of a project
there are roughly two points: the way of admission, the rate of return of offline development
is it simply to give money to the project party? Is sharing the benefits of offline development very outrageous
as far as I know, pocc mode is to spend money to buy digital currency, POC is using POC to replace mining machine, mining machine proces ore, and sells it in the exchange. The model is similar to bitcoin, but different. Moreover, in the process of transaction, the project party can't receive any money at all, and they all transfer their own business. This greatly limits the project side to circle money. And basically a miner can be realized once in about 6 days. It's also very secure for money. Secondly, the development of offline, can get about 3 poccs a day, this should not be outrageous
1. At present, the supervision of all digital currencies is not perfect, including bitcoin, Ethereum EOS and other top digital currencies in the world
2. Clearly reply that you are not a MLM company. You can understand pocc as a start-up company. It wants to go public (make it into a big currency like bitcoin Ethereum EOS). If you succeed, everyone will benefit. If you fail, your investment will not be affected, because you can recover the cost in six months
3. For those who say they have been cheated, publish their ID or your currency address, and the platform will query the records for you to see if you have been cheated
4. Pocc skin shrimp public chain, with (non small) can query the relevant information, non small is a professional third-party information website, all digital currency can query
5. As far as I know, there are a group of professional spurts on the Internet. One is to release negative news to attract attention and improve their own traffic. The second is to blackmail the platform for sealing fees
6. Since September 2018, there has been no loss and it is still running steadily. The benefits are consistent. Your friend tried, earned, recommended to you, you are still hesitant, to the Internet to find those who have not played the project, do reference, you will never earn money
7. Many people have been cheated by blockchain and various kinds of funds. You've heard about it and seen it. But you just didn't get involved
8, those who say pull the head, the tiktok speed version of the top page speed version does not pull the head? Wechat does not attract people in the initial stage? Alipay didn't pull the plug at the beginning? The network does not pull the head in the initial stage
9. Any project can't do without fans. Only fans can grow and last, and fans can only gain profits without loss, just like stocks. Those who hold the original stocks can make profits, but the loss is the secondary market
10. I hope those who talk nonsense blindfolded can experience it. Here's the screenshot BB.
POC is the abbreviation of proof of concept. It is a set of suggested electronic models, which can be used to demonstrate the design of teams and customers, and allow to evaluate and confirm the conceptual design scheme. The evaluation of POC may lead to the adjustment of specifications and design
POC usually runs real data on the selected server according to the performance requirements and expansion requirements of users, calculates the amount of user data and running time, and increases the amount of data according to the future business expansion requirements of users to verify the bearing capacity and performance changes of the system and platform

precautions for POC test:
POC is usually used for the technical test and verification steps before enterprise bidding cloud platform, to comprehensively test the procts of different manufacturers, so as to master the technical level of each manufacturer
generally, users will give a list of test items or test cases. After environmental preparation, manufacturers need to demonstrate or give test results to customers one by one. Customers will score the test results and take the final score as the basis of manufacturers' technical level
as a manufacturer, you need to prepare for each project, and you also need to pay attention to highlight the highlight project (which is also the customer's concern or pain point). For the functions that cannot be tested in practice, we need to have corresponding countermeasures, or give a technical demonstration scheme, or have a way to walkaround, or guide and feedback to customers< br />
POC particle oxidation catalyst (POC) = particle oxidation catalyst
different from gasoline vehicles, only a few new diesel vehicles adopt exhaust after treatment technology. Automobile diesel engine manufacturers have been improving the engine and its control system to meet the emission standards
The most difficult part is to rece the emission of particulates and nitrogen oxides at the same time in the low temperature lean burn environmentthe best effect can be achieved by using diesel lean burn NOx removal catalyst and diesel particulate filter
although this technology already exists, it is very expensive. In most cases, advanced particulate oxidation catalyst POC is used, which is characterized by particulate combustion
The catalyst consists of a new low temperature coating and a metal carrier called Ecocat. At the same time, the conversion of HC and CO can reach 80% - 90%has been tested on several light and heavy engines and vehicles driven by this type of engine (engines up to Euro 0 to Euro 4 standards). The biggest advantage of this scheme is that the price is relatively cheap and maintenance is not necessary. But the sulfur content in diesel oil should be low
POC is a catalytic oxidizer for particulate matter. The working principle is to catch up the particulate matter, and then burn it through the high temperature of exhaust gas (250 ℃ - 500 ℃), so as to achieve the purpose of recing the particulate matter. POC is widely used in light truck. In addition, POC can regenerate actively and DPF needs human intervention
particulate oxidation catalytic converter (POC) can be used to rece particulate matter in diesel exhaust, which belongs to the category of oxidation catalytic converter. The conversion efficiency of particulate matter is higher than doc, but lower than DPF system. The principle is to make the exhaust gas pass through a multi fold channel without blocking, and the particles are adsorbed in the POC, and the accumulated particles are removed by oxidation combustion
because POC requires a higher working temperature, it needs to be used in combination with DOC, which is called PM Kat system by European heavy truck enterprise man, that is, DOC and POC are integrated. Under the oxidation of DOC catalyst, no in the exhaust gas combines with oxygen to form nitrogen dioxide, and the original NO2 in the exhaust gas enters the POC together. Under the action of the catalyst, the molecular bond of N O2 breaks at a lower temperature, and the generated o burns with the captured C particles to form C O2, thus effectively removing the captured particles
POC can only filter the larger carbon particles, but the ability to capture the carbon particles below PM2.5 is low, and the efficiency of recing PM is 30% - 80%, which is better than doc and lower than DPF. The price of POC is lower than that of DPF and higher than that of doc
