Ⅰ What are the good blockchain projects in 2020
The history of digital currency has developed for more than ten years since the birth of Bitcoin in 2009, with a total of Having built tens of thousands of blockchain projects and experienced the blockchain 1.0 and 2.0 eras, the blockchain is about to enter the 3.0 era, which is the era of token economy. The emergence of commercial platforms has made the 'token economy' possible and brought about With the development of productivity and the transformation of production relations.
Based on this background, the NGK Token came into being. The platform has many technologically leading R&D elites and strong support from many powerful investment companies. It is popular in the United States. Supervised by the SEC Securities and Exchange Commission.
The NGK.I0 team has been concentrating on researching and launching a profit method that combines the NGK blockchain digital currency fund and industrial ecology since 2018 to comprehensively create a more complete business ecosystem. It will surely lead the blockchain market again
As a barrier-free pass on the NGK.IO platform, the NGK pass can connect online and offline merchants from all walks of life and realize commercial applications. It not only helps The transformation and upgrading of traditional industries have also leveraged the Internet economy and promoted the development of the real economy
NGK.IO has a built-in Turing-complete programming language that users can use to construct and define their own With various features, you can develop your own applications and blockchain systems, and issue your own currency.
NGK.IO also has side chains that can be customized with one click. NGK.IO provides proprietary cross-chain Chain and cross-contract technology link the main chain and side chains together. Whether it is contract assets on NGK.IO or assets not on NGK.IO, they can be used through NGK.IO’s cross-chain and cross-smart contract Technology can freely complete value transfer and exchange.
Moreover, NGK.IO does not need to consume GAS at every step like Ethereum when running smart contracts, which makes it possible for users to use Dapps for free, which is more in line with the Internet. The product is free and relies on a business model of profit from value-added services and advertising
So we can think that Dapps developed based on NGK.IO are real Dapps.
NGK.I0 The design goal is to exceed 1 million TPS, and it is proposed that the block confirmation time of NGK.IO will reach 3 seconds. Therefore, NGK.IO will have very excellent performance and is expected to change the current situation where blockchain technology cannot be implemented
From this, we can foresee that in the future, many blockchain entrepreneurial projects will choose to issue tokens based on NGK.IO, develop a large number of Dapps that can be implemented, and attract hundreds of millions of users to use
NGK.IO is expected to form a rich and complete business ecosystem, and at the same time generate a large demand for trading tokens.
NGK.IO makes full use of the blockchain and the NGK.IO ecosystem to establish a secure, verifiable, fair, decentralized, trustless, and borderless business and financial area. The blockchain system provides innovative enterprise teams with financial services and industry incubation services such as industrial funds, Internet funds, blockchain funds, Internet of Things and artificial intelligence, and creates a world-class ecological business closed loop.
And through cross-chain, value exchange can be formed for different consumption scenarios, providing certain technical strength for the commercialization process of the global "token economy"!
I believe that in the future NGK.IO will definitely improve the speed of value exchange by leaps and bounds, thereby realizing a truly united and interoperable value network! #digital currency # #blockchaininformation # #currency circle news # #Mining Gold Rush # #currency circle news #
Ⅱ Classification of blockchains
Currently blockchains are divided into three categories, including hybrid blockchains and private blockchains It can be regarded as: generalized private chain, public blockchain and public blockchain. This means that any individual or group in the world can send transactions, the transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is currently the earliest blockchain and the most widely used blockchain. Each virtual digital currency of the Bitcoin series is based on a public blockchain, and there is only one blockchain in the world corresponding to this currency.
Extended information
1. Industrial blockchain industry blockchains: multiple pre-selected nodes in the group are designated as bookkeepers, and the generation of each block is jointly decided by all pre-selected nodes (pre-selected nodes participate in the consensus process), others Access nodes can participate in transactions but do not interfere with the accounting process (essentially, it is managed bookkeeping, but it becomes distributed bookkeeping). How many pre-selected nodes and how to determine the bookkeeper for each block becomes the main risk point of the blockchain ), anyone else can make limited queries through the blockchain’s open API. Private Blockchain Private Blockchain ((privateblockchains)): Only the general ledger technology of the blockchain is used for accounting. It can be a blockchain with exclusive written permission from a company or individual. This chain is not much different from other distributed storage solutions. At present (December 2015), conservative giants (traditional finance) want to try private blockchains, while the applications of public chains, such as Bitcoin, have been industrialized, and the application products of private chains are still being explored. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is an important concept of Bitcoin. Essentially, it is a decentralized database.
2. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks associated with encryption methods. Each data block contains a batch ofBitcoin network transaction information, verify the validity of its information (anti-counterfeiting) and generate the next block. In fact, the word blockchain does not appear in the original English Bitcoin white paper, but appears in blockchain. In the earliest Bitcoin white paper, blockchain was translated as blockchain. This is the time when the Chinese word "blockchain" first appeared. The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which came into effect on February 15, 2019. In a narrow sense, a blockchain is a chained data structure that combines data blocks in chronological order, and a tamper-proof and forgery-proof distributed ledger guaranteed by cryptography. Broadly speaking, blockchain technology is a new distributed infrastructure and computing method that uses blockchain data structures to verify and store data, distributed node consensus algorithms to generate and update data, and cryptography to Ensure the security of data transmission and access, using smart contracts composed of automated script code to program and operate data.
Ⅲ Characteristics of blockchain
1. Decentralization
The so-called decentralization refers to the use of distributed computing in blockchain and storage, there is no centralized hardware or management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system.
2. Openness
The so-called openness means that the blockchain system is open. In addition to encrypting the private information of the transaction parties, the blockchain data is open to everyone. Public, anyone can query blockchain data through the public interface and develop related applications. The information of the entire system is highly transparent.
3. Autonomy
The autonomy feature of blockchain is based on specifications and protocols. The blockchain adopts consensus-based specifications and protocols (such as open and transparent algorithms), so that all nodes in the system can freely and securely exchange data in a trustless environment, changing trust in "people" to machines. trust, no human intervention can work.
4. Information cannot be tampered
Because of this, the stability and reliability of blockchain data are very high. Blockchain technology has fundamentally changed the centralized credit creation method, using mathematical principles rather than centralized credit institutions. To establish credit at a low cost, birth certificates, real estate certificates, marriage certificates, etc. can all be notarized on the blockchain. With a global central node, they can become things trusted by the world.
5. Anonymity
The so-called anonymity means that the exchange between nodes follows a fixed algorithm.Data interaction does not require trust. Counterparties do not need to disclose their identities to make the other party trust themselves, which is conducive to the accumulation of credit.
Lianxin is a blockchain application with tens of millions of member users. It has its own Quark blockchain as a public chain, qkibill open source wallet, and independent block browser. It is a completely independent A blockchain platform where users control their own data. Quark Chainchain’s innovative blockchain plus life service platform is committed to creating better blockchain services. The Chainchain Blockchain has the above characteristics and is a real blockchain chain project.
IV What is the essence of blockchain
The essence of blockchain is a distributed ledger. For example, a bank's system is also a ledger, with a complete set of information systems to store various transaction information such as deposits and withdrawals, loans, and exchanges. There are several keywords for blockchain:
1. Distributed: The ledger is not just stored in one place, but stored in many places.
2. General ledger: You can determine through the network that you are not necessarily a machine-stored general ledger, but at least you can obtain the general ledger from the network.
3. Decentralization: "Distribution" is not general distribution, but decentralized distribution. No one can control or tamper with it, and its accounting rules are accounted for according to some designed mathematical methods. How to check and how to use it is all done according to a public method, so it is essentially a ledger.
Biying China took the lead in introducing blockchain into the crowdfunding industry, making crowdfunding more open, transparent and simple.
IV What are the applications of blockchain technology
Developing Ethereum Cat based on Ethereum, this is not considered an application, it is a bit interesting, and there is also NetEase Planet. For traceability, I have snapped up the Orange Chain made by China Enterprise Tongbao Blockchain, which is used for blockchain traceability records on Orange.
VI What is the concept of blockchain?
The English name of blockchain is Blockchain. Translated into Chinese, it is a literal translation, just like the Internet. Blockchain is actually an underlying protocol. Roughly speaking, it has several components:
The first is called distributed ledger; the second is called decentralized trust; the third is called asymmetric encryption; The fourth is called timestamp; the fifth is called smart contract. These five underlying technologies are all a bit mysterious to talk about, but everyone seems to understand them.
For example, why Alipay is so powerful is because it solves a trust problem in online shopping.
The buyer does not give the money to the seller first, but gives it to Alipay first. Then you verify that the goods are received and the money is OK, and then it is transferred to the seller's account. Alipay plays the role of an intermediary.
Of course, Alipay was not invented by Jack Ma. One of the earliest founders of PayPal was also Elon Musk. This was his first pot of gold, using the Internet to solve centralized trust.
Ⅶ sto and ico in the blockchain marketWhich one is more worthy of investment
STO (Security Token Offering), translated as "Security Token Offering". Judging from the name, it is similar in concept to ICO and IFO, and is a way of issuing tokens. The most significant feature of STO is that the tokens issued have securities properties and are regulated by securities agencies (such as the U.S. SEC) and relevant securities laws and regulations.
ICO (abbreviation of Initial Coin Offering), initial coin offering, originated from the concept of initial public offering (IPO) in the stock market. It is the first issuance of tokens by blockchain projects, raising Bitcoin, Ethereum, etc. Behavior of universal digital currencies.
Both ICO and STO are products of digital capital. In the era of blockchain, it is not black and white, and eggs should not be put in the same basket. So how to invest? It depends on whether you want to be an "egg" person or an "egg" person.
If you are an ordinary investor, you can register a digital wallet and conduct independent buying and selling on major trading platforms such as Currency/Binance; and for project investors, you can issue your own coins. Achieve the goal of more financing. To issue currency, you first need to have a main company. Now the domestic market does not allow it, so they have moved overseas. Currently, Singapore is the mecca for Asian blockchains, mainly because the policies and atmosphere there are very relaxed, and the public is registered in Singapore. Non-profit foundations do not need to pay taxes on overseas projects, and the Singapore Inland Revenue Authority will not tax local capital injections and investments.
The process of registering a Singapore foundation: the ID cards of 2 registered directors and the company name are required for verification. Registration can be carried out after verification. The total time required is 10-25 working days.
Due to the particularity of Singapore’s economic environment, in the later stages of the foundation, it is legal to carry out actions such as ICO and other currency transactions. Friends who are in the blockchain industry know what to do. All ICO blockchains are registered in Singapore. For more compliant operations in the future, it is recommended that investors register as early as possible with a Singapore foundation for financing.
VIII What is the definition of blockchain
Blockchain is a term in the field of information technology and is a shared database.
From a technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency.
These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for the blockchain to create trust. The rich application scenarios of blockchain are basically based on its ability to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects. Blockchain is a distributed data storage, peer-to-peerNew application models of computer technologies such as point transmission, consensus mechanism, and encryption algorithm.
Applications
Blockchain has potentially huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.
