recently, "bitcoin broke through $8000" has been on the hot search. For a while, bitcoin rose, reborn rose sharply, and Ethereum led the rise... A week later, this big play dominated by bitcoin didn't seem to come to an end, and the trading volume was once pushed up to 100 billion US dollars

in the investment world, "madness" and "fear" coexist. Today's "madness" stems from last year's long-term "fear". However, this time, coincola Cola Research Institute tracks and analyzes the technical indicators behind the rising market, and deconstructs the "passion" of the market with the "rationality" of data< (1) mining and bitcoin price

start with the relationship between mining and bitcoin. The core technology of bitcoin is "blockchain", which is connected by blocks. Each block corresponds to a bill. All transaction information and transfer records of bitcoin are recorded on the blockchain. Every other point in time, the bitcoin system will generate a random code on the system node. Due to distributed accounting, all computers on the Internet can search for the code. Whoever finds the code will generate a block and then get bitcoin. This process is mining. Calculating this random code requires a lot of GPU operations, so miners need to use mining machines with massive graphics cards to make profits

1. Bitcoin computing power: starting to pick up

remarks: June 2018-may 2019 bitcoin hash value

data source: bitcoin visual, coincola Research Institute

the above figure shows the bitcoin hash value. The hash value of the bitcoin network represents the computing power of the blockchain. The growth of computing power means that miners increase mining investment or increase the number of miners. Since the second half of 2018, the hash value has recovered from falling back to picking up, from 32eh / s at the end of the year to 50eh / s now, and the recent growth trend is remarkable. The continuous growth of bitcoin hash value (representing computing power) indicates that the market is optimistic about the future of bitcoin

2. Mining difficulty: stepped up

remarks: bitcoin difficulty from June 2018 to may 2019

data source: bitcoin visual, coincola Research Institute

the figure above shows bitcoin difficulty. Since 2019, the difficulty of bitcoin mining has increased in a step-by-step manner, from the low 5T to the current 7T. It can be seen that the rapid rise of bitcoin in this round has reced mining costs and increased market entry personnel. The increasing difficulty of mining means that there are profit opportunities in cryptocurrency market, and the market is generally optimistic< (2) the number of active addresses and transactions on the chain are important indicators reflecting the activity of cryptocurrency, which are highly correlated with the price of cryptocurrency

1. The number of active addresses on the bitcoin chain: a straight line rise

remarks: the number of active addresses on the bitcoin chain from June 2018 to may 2019

data source: coinmetrics, coincola Research Institute

active addresses refer to the addresses where transactions have taken place every day, that is, how many independent addresses conct transfer transactions on the chain every day. Since 2019, the number of active addresses on the bitcoin chain has been rising, especially in recent years. From 540.60143k in January to 832.592k now. It shows that the rapid growth of active users of cryptocurrency is a very positive signal for the market

2. The number of transactions on the bitcoin chain: continued to rise

remarks: the number of transactions on the bitcoin chain from June 2018 to may 2019

data source: bitinfo charts, coincola Research Institute

since 2019, the number of transactions on the bitcoin chain has continued to rise, from 235k in early 2019 to 374k now. Moreover, since April and may, after two rounds of sharp rise in the price of bitcoin, the number of transactions on the chain has remained at a high level, even showing signs of a short-term surge< (3) lightning network and bitcoin price

in essence, lightning network adds a layer to the basic layer of bitcoin blockchain in order to make the transaction fast and cheap. With the existence of lightning network, users can remit money to each other at any time and pay very little. Lightning network represents not only the technical level of bitcoin, but also the important basis of bitcoin value

1. Lightning network nodes: rapid growth

remarks: bitcoin lightning network nodes from January 2018 to may 2019

data source: bitinfo charts, coincola Research Institute

the test version of lightning network started on the bitcoin main network on March 15, 2018. The number of lightning network nodes was only 64 at the beginning of 2018 and increased to 2329 at the end of 2018. Since 2019, the number of lightning network nodes has increased rapidly, and now it has reached 4289. In less than half a year, the number of nodes has doubled. The continuous expansion of nodes indicates the continuous upgrading and development of bitcoin lightning network technology, which is an important indicator of bitcoin price

2. Lightning network capacity: speed up

remarks: bitcoin lightning network capacity from January 2018 to may 2019

data source: bitcoin visual, coincola Research Institute

the data above shows that as of May 15, 2019, bitcoin lightning network capacity has increased to 1039 BTC, equivalent to 833usd, while at the beginning of 2019, it is only 504btc, Lightning network capacity doubled, and the growth rate accelerated. This means that the expansion of bitcoin has been well solved in lightning network technology, which will help keep the payment channel active and effectively support the functional application of bitcoin

the performance of mining, chain trading and lightning network is closely related to the price of bitcoin. On the one hand, the rise of bitcoin price acts as a catalyst to stimulate its performance in mining, chain and lightning network; On the other hand, mining, chain trading and lightning network are the important cornerstone of bitcoin price trend and the important basis of bitcoin price expectation<

2.

First of all, we need to know what digital currency is. Digital currency is characterized by decentralized transaction currency. The most famous is bitcoin. However, digital currency has not been recognized by China in recent years. Recently, China plans to issue China's digital currency DCEP, or DC for short. Digital currency itself is currency. When you ask how to make money, you are actually asking, How does money make money? In fact, there are many channels. First, we will have funds in the later stage to conct private placement of digital currency. Second, how do we usually earn RMB? Now, when we promote the use of digital currency in China, we will use digital currency to earn money

as a digital currency, in fact, what China issues is similar to legal currency. The purpose of legal currency is to stabilize the RMB, which should float up and down 1:1 per second. According to different exchange rates, DCEP: usdt will float up and down 7:1. In the later stage, it may be 1:1 according to China's increasing competitiveness, which is also graally declining in recent years

as a digital currency, if you want to make money, there are many ways. Major exchanges can convert it into different digital currencies. Other digital currencies may not be as stable as usdt and DCEP, and the price will keep rising and falling according to the demand. At this time, we can buy and sell stocks in a similar way to earn the price difference, If you don't enjoy it, many digital currency exchanges provide contracts, which can buy and sell multiple times, or be bullish or bearish, or even hundreds of times at most. Many people get rich through this way, but there are also many people who lose their property. In addition, this kind of exchange will make your currency return to zero in a way, We should be wary of many such exchanges running away - refer to the second largest exchange checked OK exchange

in addition, as a national form of digital currency, there should be short positions. For example, China's state-owned enterprises carry out digital transformation to form community-based currency, which may be airdropped according to the DCEP they hold. This is my guess

in addition, defi's liquidity mining, commonly known as market making, is more popular now. In the later stage, it may replace the exchange. Everyone is an exchange and can charge a handling fee

3.

It's a kind of virtual currency that attracts a wave of people to reap, and then it slowly exits. How can it reach a new high? There aren't so many idiots

1. When bitcoin is fried to $150000, a drop of $12000 seems insignificant, but this is not the final price limit< p> Bitcoin has only technology cost and service provider cost, and other things are fried. It has no so-called privacy ring the period. There are many similar mining activities, but it is the first to get up, so it is in the lead, and after other mining activities are yellow, it is still strong and can be fried higher and higher

the people who defend the legal line are much smarter than the people who want to play with the virtual currency. Why not put them in? It's because we are afraid that we will become others' leeks, but some of us have & lt; Society limits him to make money; My heart. Let me just ask you a question: if you have a lot of capital, you have 200 billion US dollars, will you take the opportunity of bitcoin's fall to buy it crazily, and then you will be able to understand what it is worth

4. For modern enterprises that increasingly rely on Internet applications, the ever-changing security threats and changing regulations and standards make it a big problem to maintain a reliable network environment

in today's global economic environment, companies and enterprises have never been so inseparable from each other as now. However, although it is more convenient to do business on the Internet, it is more difficult to ensure the security and reliability of data exchange and communication. For large and small enterprises, the changing security threats and changing regulations and standards make the maintenance of reliable network environment a big problem

here are ten security policies to establish online trust relationship inside and outside the enterprise. Although these strategies are not comprehensive, they focus on the top ten threats faced by enterprises: E-mail system, traditional password security mechanism, identity authentication, phishing and so on

1. Without SSL protection, data integrity will be endangered

SSL server certificates should be deployed for your entire enterprise as soon as possible. SSL is the most widely deployed security protocol in the world. It should be deployed on any server to protect all kinds of confidential and personal information transmitted from browser to server

SSL encryption is one of the most important technologies used to protect websites, intranets, extranets and other server based applications. Without it, the integrity of data exchanged through public and private networks will be endangered, which will ultimately affect business continuity and profits. SSL can protect network access, online contact and digital transactions, because it can establish a secure channel between the server and the user

in the past few years, people's understanding of the advantages of SSL technology has been greatly improved. More and more users pay attention to the padlock symbol that indicates that the session uses SSL encryption

nowadays, thousands of websites have installed X.509 special server digital certificate, which can activate SSL between browser and server. All modern web browsers and servers have integrated the function of supporting SSL. Therefore, from the enterprise point of view, you only need to install the certificate on the server. Once the browser and the server exchange signals, all the data transmitted from one side to the other side are encrypted, which can prevent any eavesdropping that may endanger the security or integrity of the transmitted data

2. Without reliable physical and network security, sensitive enterprise data will be in danger

using firewall, intrusion detection, client PC virus software, server based virus checking, and ensuring the latest security patches on all systems can prevent most types of threats from affecting the company's business, damaging sensitive data, or threatening business continuity

network security involves computer system and network access control, detection and response to intrusion activities. Poor security will bring huge risks: data theft, service interruption, physical damage, system integrity is endangered, unauthorized disclosure of company proprietary information

in order to protect the network access channel, we should start from the basic aspects, such as locking up the unused computers. In addition to the basic aspects, more reliable solutions include the use of key cards, hardware tokens, and biometrics to control access to particularly sensitive areas

firewall is a necessary part of network security. Firewalls restrict access from one network to another, and check and restrict all traffic through the network. Firewalls should restrict access from Internet and one internal network (such as application server) to another network (such as database). It is necessary to consider which IP addresses and ports the firewall should allow. In addition, it is recommended to use multi-layer firewalls for parts of the network with significantly different functions - one for the DMZ, a second for the web server, a third for the application server, and a fourth possibly for the database

intrusion detection system can monitor attacks, analyze and review logs, alarm administrators when attacks occur, protect system files, reveal hacker's methods, indicate which loopholes need to be plugged, and help to track criminals who implement attacks

another indispensable

means is to ensure that the virus and Trojan horse check software on all clients are up-to-date. There are thousands of viruses out there, and each new one is more cunning and destructive than the original one. Recently, several viruses spread by e-mail and spread all over the world have caused great damage and loss. A particularly reliable solution is to run server based virus software on the e-mail transmission system (such as Microsoft Exchange) to prevent the infected e-mail from being transmitted to users or infecting other clients through one client

finally, the simplest and most effective way is to make sure that you have a security patch for each latest version of all operating systems and applications. Hackers are clear about the loopholes in Microsoft's IIS Web server, and always take the site running IIS Web server as the target. Over the years, patches to plug IIS security vulnerabilities can be obtained free of charge, but there are still more than 30% of IIS systems on the Internet without the latest patches. Therefore, it is necessary to reiterate that all security patches should be applied immediately

3. Develop your own PKI system or choose managed PKI service

when a trusted third party expands a complex, secure and expensive public key infrastructure (PKI) and manages it for you, the fully managed security service can enable you to focus on the applications needed to promote the company's business development

public key infrastructure (PKI) is a tool that can use various applications in a way that was not possible in the past. If there is no effective way to issue, revoke and manage certificates, after the company deploys the welfare system on the intranet, it is not expected that employees can only use the system to query welfare information, especially if a large proportion of employees work far away. Similarly, if the access is not secure and reliable, the sales team will not be able to make full use of the company's important system: CRM system. Nowadays, many companies are restricting the use of e-mail, and many companies prohibit the use of instant messaging - all because these systems are not yet secure

the previous generation of PKI is very good in theory, but in fact, it needs to install complex hardware and software, as well as special IT personnel and special security measures to protect the system. Needless to say, all this means huge financial costs. However, PKI has been mature and innovative enough to become an outsourcing part of the application system. Trusted third party certification authority (CA) can build, maintain and manage the public key infrastructure needed by enterprises, and ensure its security. Ca, which provides fully managed services, has expertise in verification techniques and methods. Enterprises need to know the business rules they want to implement and the applications they need to deploy in order to realize business process automation. The integration point is how to use certificates in applications to implement security. Many applications already have certificate ready function, such as browser, e-mail and VPN; The increasing use of certificates has become a general trend

fully hosted security services have several important parts: flexible verification model (how can we know who someone is), management interface (who in the organization is authorized to make changes and control the process), and operation interface (how different groups in the organization can obtain certificates)

most organizations need to outsource their applications to trusted third parties to meet one or more of the following requirements: secure access, secure messaging and paperless transactions. For all large organizations, it is an important requirement that employees can safely access enterprise networks such as intranet and key applications such as CRM system. E-mail or instant messaging programs provide a mechanism to confirm the identity of the sender and protect the content from eavesdropping. Paperless transaction can fully digitize the paper-based process that needs to use the original signature to indicate the content, thus saving the time and cost of paper-based process< Free software can crack the password within 30 minutes

password security is very poor, and it is getting worse and worse, which makes your security system vulnerable to attack. It can enforce strict rules of password usage, thus greatly enhancing this defense capability

with the speed of the computer, the temptation of password cracking is increasing, which is more attractive to those criminals. As more key business systems are connected to the Internet, password cracking can gain more benefits. With downloadable free software, anyone can crack a 6-character password in 30 minutes and an 8-character password in 6 hours

you need to make rules immediately about how people create passwords and how often they change them. Password creation rules include: mixed use of uppercase and lowercase letters; Always have at least one number and punctuation; Don't use the name in your profile; The length should be at least 8 characters. The most important thing is, if you need to use your password continuously, if you input it incorrectly five times, make sure that all passwords are disabled to prevent the behavior of trying to crack the password with brute force. Run the password cracking program inside to find out the password with poor security. Then, we begin to replace these weak passwords with low-cost, outsourced authentication and digital SSL certificate services

5. E-mail will reveal your business secrets

issue digital client certificate for all employees to sign / encrypt e-mail, so as to protect enterprise data and further make employees feel at ease about the source, authenticity and confidentiality of all enterprise communications

secure messaging (think of initial e-mail and subsequent instant messaging and voice over IP [VoIP]) is designed to ensure that only the intended recipient of the message can read it. The more frequently e-mail is used, the more important it is to the company's confidential information. This is especially true for emails sent to

outside the enterprise. E-mail is transmitted from one server to another through the public network in clear text format. Servers along the way can and do save all the messages they receive and have the right to do so. On most e-mail systems, the sender has no control over who can receive the forwarded e-mail messages, and there is no trace of someone receiving the forwarded e-mail messages

any two employees can sign and encrypt messages sent to each other as long as they simply exchange client certificates, so as to ensure that these messages have not been tampered with; The source was confirmed; Any difference between the two
