برای طراحی و ساخت یک کارخانه، لازم است که مواد خام ورودی به کارخانه و محصولات خروجی مشخص باشند. برای بررسی اقتصادی طرح، مقدار محصولات خروجی با نوشتن موازنه جرم بدست می‌آید. همچنین غلظت و کیفیت محصولات خروجی به نیاز بازار بستگی دارد. به این ترتیب بدون در نظر گرفتن سرمایه‌گزاری اولیه می‌توان طرح را به صورت ابتدایی بررسی نمود. در مراحل بعد لازم است که اندازه دستگاه‌های مختلف کارخانه مشخص شود. اندازه بیشتر دستگاه‌های مورد استفاده در صنایع شیمیایی به دبی ورودی وابسته است. بنابراین لازم است دبی جریان‌های ورودی و خروجی از همه دستگاه‌ها مشخص باشد و این کار با استفاده از موازنه جرم امکان‌پذیر است.
Coinbase is a terrible and unprofessional company. They’ve ignored my requests for escalation after providing no feed back on the issues I am having. These issues are costing this customer not only monetarily, but due to the lack of transparency with new policies in which coinbase will hold your funds hostage for 10 days while advising that it can be transferred “instantly” is not only false, but malicious contempt.

لماذا Blockchain مهم جدا


While it is spent online, Bitcoin is essentially like a form of cash in this regard – the person in possession of the funds is effectively the owner, and if the private keys which authorize spending are stolen, there is little recourse. While one can often track the movement of stolen funds on the blockchain, it’s impossible to reverse the transaction, making Bitcoin holdings a popular target for cybercriminals.

Cryptocurrencies are experiencing a moment of unprecedented attention and speculation for several reasons. 1) The value of Bitcoin has been steadily climbing through 2017, with Ether seemingly poised to overtake the cryptocurrency giant any day; 2) Blockchain technology has purposes above and beyond cryptocurrency, and has been hailed by some as the backbone of the future financial system; 3) The increasing number of people who see cryptocurrency as a form of investment similar to gold. If cryptocurrencies stabilize in value, buying Bitcoin or Ether has the potential to be a worthy venture.

If the second capturing group cannot does not match the input string, the value of the last successful match defines the value of the Group object.
In December 2017, two Chicago exchanges - CME and CBOE - launched Bitcoin futures trading, and thus unlocked the cryptocurrency market for institutional investors. The exchanges guarantee that the parties of the futures contract fulfill their respective obligations based on the applicable legislation. It means that the market players that were discouraged by an unregulated stance of the digital asset got a handy tool to gain exposure or hedge Bitcoin and benefit from the price fluctuations.

The individual investor should differentiate the anonymity of the cryptocurrencies with the fact that transaction processes are recorded and validated using the Blockchain technology. Otherwise, the Bitcoins pass-through information would not be available. However, the process of performing this data recording requires a high computational work, as well as a lot of time.

Yes. Bitcoin has not been made illegal in any country to date, although some nations restrict its use more heavily than others. Bitcoin is often associated with crime, because it can be used to make criminal transactions. However, this is true of any currency. Bitcoin is harder for authorities to trace than digital fiat transfers, but easier to trace than cash, and most criminal transactions in the world are made with fiat, not Bitcoin.
Coinbase is one of the most popular ways to buy Bitcoins, and it is now looking to take the ease of use that it provides one step further.

Tiger Global Management is leading this financing round, while the other participants include Wellington Management, Andreessen Horowitz, Y Combinator Continuity, Polychain, and others.

If you do have this much money tied up in Bitcoin, though, you may want a more secure space to store it. If this is the case, Coinbase offers a Coinbase vault, which has time-delayed withdrawals (giving you 48 hours to cancel a withdrawal) and the option of multiple approvers, increasing security by ensuring that all withdrawals are approved by multiple people. They also offer a multisig vault, which is basically an even more involved and more secure vault, requiring multiple keys to unlock.

There are several differences between a blockchain and a database, including the level of control. Blockchains are under a decentralized control, whereas a centralized database creates a dependent relationship between users and administrators.
