5 digital currency with the biggest increase in recent years

1. In recent years, blockchain digital assets represented by bitcoin have become popular all over the world. Financial institutions, technology companies, investment companies and other participants at home and abroad have invested a lot of human, material and technical resources in the research, development, design, testing and promotion of blockchain digital assets. In order to realize the main characteristics of "four can and three can't" of blockchain digital assets, we can build the core technology system of digital assets by relying on 11 technologies of security technology, transaction technology and trusted guarantee technology. First of all, security technology is used to ensure the fluidity, storability, controllable anonymity, unforgeability, non repeatable transaction and non repudiation of blockchain digital assets. digital currency security technology mainly includes basic security technology, data security technology and transaction security technology. Basic security technology includes encryption and decryption technology and security chip technology. Encryption and decryption technology is mainly used in currency generation, secret transmission, identity verification and other aspects of digital assets. The establishment of a perfect encryption and decryption algorithm system is the core and foundation of the digital assets system, which needs to be customized and designed by the national password management organization. Security chip technology is mainly divided into terminal security mole technology and smart card chip technology. Digital assets can be traded in the form of mobile terminal based on terminal security mole. As the carrier of secure storage and encryption and decryption operation, terminal security mole can provide effective basic security protection for digital assets. Digital asset system trading platform blockchain technology research and development of data security technology, including data security transmission technology and secure storage technology. Data security transmission technology transmits digital asset information through ciphertext + MAC / ciphertext + hash to ensure the confidentiality, security and non tamperability of data information; Data security storage technology stores digital currency information by means of encryption storage, access control, security monitoring, etc., to ensure the integrity, confidentiality and controllability of data information
transaction security technology includes anonymous technology, identity authentication technology, anti plicate transaction technology and anti-counterfeiting technology. Anonymity technology realizes controllable anonymity of digital assets through blind signature (including blind parameter signature, weak blind signature, strong blind signature, etc.) and zero knowledge proof; The identity authentication technology verifies the user's identity through the authentication center to ensure the validity of the digital asset trader's identity; The anti plicate transaction technology ensures that digital assets are not reused by means of digital signature, serial number and time stamp; Anti counterfeiting technology ensures the authenticity of digital assets and transactions by means of encryption and decryption, digital signature and identity authentication. Secondly, the online transaction and offline transaction of digital assets are realized by transaction technology. Digital asset trading technology mainly includes online trading technology and offline trading technology. As a legal currency, digital assets should not be rejected by any unit or indivial, and can be traded online or offline. Online transaction technology realizes online transaction of digital assets through online device interaction technology, online data transmission technology and online transaction processing; The off-line transaction technology realizes the off-line transaction of digital assets through the off-line device interaction technology, off-line data transmission technology and off-line transaction processing technology. Finally, trusted guarantee technology is used to provide a safe and reliable application environment for the issuance, circulation and transaction of digital assets in blockchain. Digital asset trustworthiness assurance technology mainly refers to trusted service management technology. Based on trusted service management platform (TSM), it ensures the security and trustworthiness of digital asset security mole and application data, and provides security chip (SE) and application life cycle management function for digital asset participants. Trusted service management technology can provide application registration, application download, security authentication, authentication management, security evaluation, trusted loading and other services for digital assets, which can effectively ensure the security and credibility of digital assets system
what is blockchain? Blockchain technology, also known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records. Blockchain technology development blockchain technology development what is a blockchain system? Blockchain system is a database system with integrity. The data written into the system will be automatically copied to the nodes of the blockchain, which can achieve transactional data preservation, support the management and development of databases in various instries, and be proced in combination with various needs. 294.497 billion US dollars, or 2.60%. This week, five new projects entered the top 100, namely FST, ZB, Wix, wax and MXM. On August 11, the price of bitcoin was $11523.58, up 3.20% from last week, and Ethereum was $216.09, down 3.86% from last week. The 24-hour turnover of this week increased by 2.63% over the same period last week; Among the top 100 projects, the total market value and average market value of currency projects increased significantly, and the classification composition of global blockchain assets top 100 projects was stable.

2. Although many people didn't seize the opportunity of bitcoin's boom, it's not too late to invest in virtual currency. Because there are more currency categories in the virtual currency market, investors have more choices, and the market is more standardized< As the originator of virtual currency, bitcoin's investment value still exists although its market situation is far worse than before. On many virtual currency platforms, the share of bitcoin transactions accounts for a large proportion. Take domain kingdom for example, its transaction volume accounts for 75% of the total amount of virtual currency transactions
lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has a significant difference
the token on the Ethereum blockchain is called ether, and its code is eth. It can be traded in many cryptocurrency markets, and it is also the medium used by Ethereum to pay transaction fees and computing service fees
xem is a new type of digital virtual coin based on Java. It adopts the newly invented synchronization solution based on proof of importance poi. It is said that xem is the first cryptocurrency to realize multi signature at the block chain level
in fact, bitcoin, Leyte or ether can be bought and sold in 2019. The important thing is that virtual currency can also be bought and sold in the form of contract transaction
the so-called contract transaction means that no matter whether the market price is rising or falling, as long as the correct trading direction can be judged at the corresponding time, the investors can make profits, and the transaction cost as low as $5 in the realm Kingdom makes it easier for ordinary investors to participate in it
in general, 2019 is full of new opportunities, and some potential digital currencies have also been well developed to a certain extent. But when we invest, we must not be too careless. We must choose a formal and secure platform.

3. Bitcoin, of course, is the hottest one. In addition to bitcoin, there are also:
1. Litecoin is similar to bitcoin, which is also an encrypted digital currency, and its price has risen sharply recently. It is a P2P open source digital currency, which can be regarded as a branch of bitcoin. However, although lightcoin is based on bitcoin protocol, it does not require very high computing power. It can also be mined using ordinary computers. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
2. Namecoin
namecoin is also based on bitcoin, which is another branch of open source. Namecoin is a distributed DNS protocol -- generally speaking, it can transform the website name (such as ifeng. Com) that can be understood by human into the address that can be understood by machine. As its own DNS, this kind of currency can operate outside the normal Internet, so it can break away from the control of ICANN
the monetary value and domain name of namecoin are stored in the user's blockchain records, limiting the total number to 21 million
3. Peercoin
peercoin is a peer-to-peer variant of bitcoin, which can improve mining efficiency and security, and improve safeguard measures to avoid group mining. Now, group mining has been considered as a potential defect of bitcoin. According to the statistics of emerging currencies by coinmarketcap.com, peercoin currently ranks fourth in the market value of digital currencies
4. Primecoin
primecoin is a cryptocurrency similar to bitcoin, but it uses a completely independent mining algorithm. Bitcoin uses the hashcash algorithm, while prime coin uses the long Cunningham chains to create the value of money - a sequence of prime numbers named after mathematician AJC Cunningham
in the process of bitcoin mining, as the amount of money goes on, the difficulty will increase sharply. But prime is different. Every time a primecoin is mined, the mining difficulty will increase slightly, and the process is much more stable< 5. Feathercoin

based on the design of litecoin, released in April 2013, can adjust the mining difficulty more frequently than litecoin. Feathercoin will be updated frequently, adding new features and improvements to eliminate malicious mining behavior

6. Novacoin

another P2P digital cryptocurrency. Novacoin is different from most other currencies in that it integrates a protection mechanism in the currency core, which can identify illegal mining activities

the total number of novacoin is limited to 2 billion, which is considerable. If necessary, the total can be adjusted upward

7, infinitech

published in June 2013. A by-proct of litecain. According to the mining situation and the total amount of money, infinite money can frequently adjust the mining difficulty ratio< Megacoin was only released in the fourth quarter of 2013, imitating bitcoin in the early stage. The total number of megacoin is limited to 42 million, which can be mined like other virtual currencies. Its biggest selling point is brand publicity, which other digital currencies lack< It was released in 2013 and is still in its infancy. In the security part of quarkcoin, nine independent loops are deployed and six different algorithms are used.

4. Does not exist, now want to buy digital currency to make money? I just want to ask you a question. If you don't choose the mainstream, the rest of the junk's circulation plate is just a little money. If you hold a little more money, are you sure you can sell it out? To put it bluntly, currency is a market value. What can pull a wave at the beginning of the market is speculation. That is, you can buy the currency price with very little money, and then you are fooled into buying it. When you want to sell, after the speculation, no one will buy it. Who will pick up your offer?

5.

Generally, the excellent digital currencies are mostly imported procts, such as bitcoin, Leyte coin, ether coin and so on. However, the domestic Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects of European crowdfunding are excellent digital currencies

digital currency (English: digital currency) is an alternative currency in the form of electronic currency. At present, no central bank of any government has indicated that it will issue digital currency, and digital currency does not have to have a benchmark currency and a central bank

it is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography
