Digital currency Nova

1. 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.

In recent years, blockchain and artificial intelligence have been very popular

first of all, blockchain is to establish a decentralized network. The so-called decentralization means that the network does not belong to you or me

it belongs to everyone

Artificial intelligence is a new technology science that researches and develops the theory, method, technology and application system for simulating, extending and expanding human intelligence. In other words, "machine self-learning"

in this way, we can think about the combination of blockchain and artificial intelligence

first of all, we need to understand that blockchain can be divided into three stages

However, in the first three stages, there are some problems, such as the lack of decentralization, low scalability, the mismatching between the incentive of the blocker and the best profit of the whole network, and the network always running at the maximum capacity. Serious waste of resources and rece efficiency

so can we combine artificial intelligence with underlying public chain technology to solve these problems

The answer is yes! And there has been team research and development, and has made a certain progress

Velas is a public chain that enhances its consensus algorithm through artificial intelligence (AI) optimized neural network, and carries out self-learning and self optimization. It is committed to improving the security, interoperability and high scalability of the transfer process and intelligent contract. Velas adopts the dpos consensus enhanced by AI, which completely realizes decentralization without recing the security and transaction speed. Not only that, AI chooses who to mortgage the token according to the needs of the blockchain; Velas only blocks when needed; Every 1 second to every 2 minutes; Scalability (up to 30000 TPS); Block procers are selected by artificial intuition

3. This is a new stage proct, which is more oriented to the public, provides users with a simple and easy-to-use proct experience, cuts off the barriers for users to enter the defi world, and feels the ultimate experience of no threshold, zero handling charge and second to account. If you don't understand, please feel free to ask questions

4. The combination of blockchain and shipping instry is mainly reflected in the accumulation of transaction and operation data of enterprises through shipping blockchain to form a large database, and then build a full process automatic blockchain system, thoroughly open up all links of the platform, and form an information sharing channel. It's said that chain Nova does this. I don't know if there is any cooperation.

5. At present, we have cooperated with a cloud stream blockchain company to solve the paperless port problem. In my opinion, the application of blockchain in the shipping instry has three positive points:
1. Changes in the operation mode of shipping supply chain. The traditional operation mode will change, and the functions of some organizations may also change. For example, the freight forwarding related organizations may be transformed into the organizations specialized in providing knowledge services and technical services. On the one hand, the decentralized operation mode of blockchain can not only bypass some intermediate institutions, but also simplify the operation process, improve the operation efficiency and save the operation cost. On the other hand, payment activities based on blockchain are programmable, that is, smart contracts. With smart contract, a large number of documents can be eliminated, and shipping can realize paperless operation, so as to achieve the purpose of cost saving. At the same time, through the smart contract, the fund flow between the nodes becomes safe and efficient, which may bypass the third-party institutions (such as banks) to complete the payment
2. Change the port and shipping electronic data exchange system. Firstly, blockchain will realize the exchange and application of international trade bill of lading and other electronic documents among the relevant subjects of trade and transportation; Second, the blockchain will realize the integration of "logistics, information flow and capital flow" in the international supply chain, and replace part of the logistics to form a stacking mode of online trading channels. When problems occur in the process of cargo transportation, the consignor, customs, carrier and insurance company can trace reliable electronic evidence, so as to clearly define the responsibilities of all parties and improve the processing efficiency of payment, settlement and claim settlement. In the future, all kinds of legal documents involved in international trade can adopt blockchain solutions similar to bill of lading information exchange to achieve safe, reliable and mutual recognition transmission
3. Change credit evaluation system and innovate financial services. The use of blockchain for complex transaction scenarios involving multiple transaction subjects should be meaningful. The important point of risk control is whether the transaction is real. Because the underlying data is connected, it can solve the pain point of supply chain finance instry. In the era of platform, if the credit related information of relevant transaction subjects is stored on the blockchain and can be easily obtained, then the point-to-point trusted transaction can be directly concted between transaction subjects, and the role of intermediary is closer to that of technical consultant. In fact, the application of blockchain technology is graally transforming from digital currency to "blockchain +" and from financial field to non-financial field such as Internet of things. In addition, after putting the capitalized shipping resources into the cloud in digital form through the blockchain, the transaction and financing will be more flexible, and the tracking and management of assets will be more convenient.

6. Digital currency is the abbreviation of digital currency. It is an alternative currency in the form of electronic currency
both digital gold coin and password currency belong to digiccy. It can not be completely equivalent to the virtual currency in the virtual world, because it is often used for real goods and services transactions, not limited to online games and other virtual space. At present, the central bank does not recognize or issue digital currency, and digital currency does not have to have a benchmark currency. The popular digital currencies in 2015 include bitcoin, Leyte coin, Ruitai coin, thousand gold card, etc. At present, there are thousands of digital currencies issued all over the world
China's central bank is also planning to launch its own digital currency, but the design concept of this digital currency and bitcoin are different from nature. The key point of the digital currency to be manufactured by the central bank is the control right, which can also be said to be the digitization of paper currency< Bitcoin, of course, is the hottest one. In addition to bitcoin, there are also:
1. Litecoin is similar to bitcoin. It 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 it is based on bitcoin protocol, it does not require very high computing power, Lightcoin's algorithm is derived 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 is also based on bitcoin, which is another open source branch. Namecoin is a distributed DNS protocol, It is able to change the website name (such as ifeng.com) that can be understood by human beings into the address that can be understood by machines. As its own DNS, this currency can operate outside the normal Internet, so it can be free from the control of ICANN.
the monetary value and domain name of namecoin are stored in the block chain records of users, limiting the total number to 21 million.

7 Infinitcoin
released in June 2013. It is a by-proct of litecoin. According to the mining situation and the total number of currencies, infinitcoin can frequently adjust the mining difficulty ratio.
8. Megacoin was only released in the fourth quarter of 2013 and imitated bitcoin in the initial stage. The total number of megacoin is limited to 42 million, which can be mined out like other virtual currencies, This is exactly what other digital currencies lack.
9. Quarkcoin was released in 2013 and is still in its infancy. The security part of quarkcoin deploys 9 independent loops of encryption and adopts 6 different algorithms

The full name of public chain: public block
chains

means that any indivial or group in the world can send transactions, and transactions can be effectively confirmed by the blockchain, and anyone can participate in the consensus process. Public blockchain is the earliest and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain. There is only one blockchain corresponding to this currency in the world

with its transparent and tamper proof features, public chain improves the trustworthiness of the network, such as the app we use everyday

when you browse news on your mobile phone, the app will actually record your preferences and sell them to others for profit or keep them for your own use, although it can make a statement without disclosing your privacy

but the end result is often a lot of harassment calls e to privacy leakage

public network can solve this problem, if you don't want your privacy to be disclosed, then you can not be disclosed

in the public chain network, only the consensus of all people in the network can play a decisive role, rather than the centralized organization covering the sky

in the current public chain network, we often see that the project team tampers with the white paper at will, and the users are fooled around like monkeys

so a team began to create a more fair public chain in the network governance, that is, the color platform I will mention

color platform gives more rights to the community, establishes Operation Committee, arbitration committee, color Council and public fund. This seems to be a bit complicated. Simply put, the color Council is a group of users with more than 50000 coins. They need to make enough contributions to the color network to get public fund votes. On top of the color Council, nine members are elected from the color Council to form an operation committee to decide the technical development of color. It's fair, "you've proved that you can contribute enough to color, so you can have more power."

the essence of public chain network is fairness, and the public chain serves most people in this network. The governance mechanism of color platform is excellent, and I will continue to look forward to the follow-up development of color platform< br />
