⑴ What is the abbreviation of blockchain
Blockchain characteristics:
1. Decentralization. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes self-verification, transmission and management of information through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain.
2. Openness. The technology foundation of the Blockchain Blockchain is open source. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface. Therefore, the entire system information is highly transparent.
3. Independence. Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the Bu Nizhao system. , without any human intervention.
4. Security. As long as you cannot control 51% of all data nodes, you cannot manipulate and modify network data at will. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.
5. Anonymity. Unless required by legal regulations, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be done anonymously.
⑵ How to trade pi coins
1. The global pi coin exclusive trading platform "pi shop" has been launched. Users can go to the official website to sell or purchase pi coins.
2. Pi coins need to be mined with a smartphone. The software does not need to be turned on regularly and has no impact on the performance of the phone. It is a free mining currency.
3.pi coin is an encrypted virtual currency similar to Bitcoin. It is a social blockchain project pioneered by a PhD team from Stanford University.
Extended information
1. Pi Network, referred to as Pi, claims to be a blockchain project that everyone can participate in. How to play Pi is very simple. Just download the APP on your mobile phone and click it every 24 hours to receive mining profits. All Pi coins are mined by users. And when the number of users reaches 100,000, every time the number of users increases by 10 times, the mining revenue will be halved. For example, when the number of users went from 100,000 to over 1 million, production has already been reduced once.
2. According to the current growth rate, the number of Pi users is expected to exceed 10 million in December. According to the description in the white paper, the community will vote to decide whether to halve or stop production directly. Of course, this is the uncertainty that Pi will face next, and it is also a topic of ongoing debate in the community.
1. Pioneer’s basic speed is the same for everyone. It is currently 0.2π/h2. Contributor’s safety circle bonus. Each person can attract up to 5 people to join him.security circle (and these 5 people are not required to register through your invitation code). The maximum safety circle reward = 5 × 20% × basic speed = 0.2π/h3, guanxinqian invitation bonus. The more people you directly invite and the more active users you have, the faster the mining speed will be. For example, if I invite 10 people and they are all active, then my invitation reward = 10 × 25% × (basic speed + safety circle bonus). To sum up, Pi does attract people, but the invitation only has a first-level interest relationship; besides, Pi It does not require you to make any financial investment, and it is a truly zero project. Pi does not meet the two characteristics of MLM, so it is not a MLM or a scam.
2. As a mature BitTorrent Currency investors must have an optimistic attitude, a professional spirit, and a fanatical enthusiasm for learning, in order to truly survive in the harsh financial market and achieve long-term development. These trading mentality will lead to losses!
⑶ What is data blockchain (BlockChain)
What is data blockchain (BlockChain)? 1. Data blockchain is an important concept in the Bitcoin financial system. The transaction record data on the entire Bitcoin network is recorded, and this data is shared by all Bitcoin nodes. Through the data block, we can query the history of each Bitcoin transaction.
2. Example :
There are three persons A, B, and C. All the funds of A and B are kept by C. And every fund transaction must be recorded by C. Now suppose that A and B each have 1 million, which is kept by C. .Then:
A spends 80,000 yuan to B, then C's account book record will subtract 80,000 yuan in A's name, and add 80,000 yuan in B's name.
B reverses 5 If A pays 50,000 yuan to A, C will add 50,000 yuan to A's name in the account book, and subtract 50,000 yuan to B's name.
If A spends 50,000 yuan to B, C will record it in the account book above, subtract 50,000 yuan from A’s name, and add 50,000 yuan to B’s name.
3. The role of the data blockchain is similar to that of C’s account record book. It records the use of The user's ownership of Bitcoin and the records of all users' Bitcoin transactions. However, this "account record book" is recorded by the mining software of each Bitcoin miner on the Internet. If a Bitcoin transaction is The data blockchain confirms that the relevant information will be recorded in the data blockchain. Bitcoin’s “account record book” is called the data blockchain. All data blockchains on the Internet constitute the decentralization of Bitcoin Internet database system.
4. The essence of data blockchain technology is a method of data storage, transmission and certification that is decentralized and contained in a distributed structure. It uses data blocks to replace the current Internet center. The dependence on the server enables all data changes or transaction projects to be recorded on a cloud system, which theoretically realizes self-certification of data during data transmission.In a far-reaching sense, this goes beyond the traditional and conventional need to rely on the formalization of central information verification and reduces the cost of establishing global "credit." This point-to-point verification will produce a "basic protocol" that is a decentralized artificial intelligence A new form of IoT will establish a new interface and shared interface for human brain intelligence and machine intelligence.
Blockchain is a new application model of computer technologies such as decentralized data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system. Shanghai Heshu Software Co., Ltd. is an innovative technology enterprise focusing on the R&D and application of blockchain technology and a professional blockchain technology service provider. The team has been developing blockchain technology since 2016, and has conducted in-depth research on blockchain technology fields such as blockchain encryption algorithms, consensus mechanism network security, decentralization, and point-to-point.

What is blockchain (Blockchain) technology? Blockchain technology, referred to as BT (Blockchain technology), also known as distributed ledger technology, is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to Participation database records.

is a public list of all transactions that have been sent, which ensures that everyone knows the true owner (address) of each Bitcoin. All fully functional nodes on the network will retain a copy of the blockchain.
Block is an independent unit on the blockchain. Each block contains the hash value of the previous block (so it is impossible for someone to remove or modify any block on the blockchain without causing some of the hashes in the blockchain to mismatch), and also There are as many unconfirmed transactions as can be found on the Internet, and a number called a nonce. Someone who is building a block must find a suitable nonce so that the hash value of the block is below a certain threshold (thetarget target value). This can only be achieved by aTry all the random numbers one after another until a random number that produces the desired hash value is found. The lower the target value, the harder it is to find a suitable random number. Block creation is intentionally made so difficult to prevent someone from spending Bitcoin and then creating and advancing his own blockchain that does not contain the transaction that shows the Bitcoin has been spent, a wipe The transaction record just now allows him to spend the Bitcoin twice. When a valid block is created, it is distributed throughout the network and the search for the next block begins based on this block.
What is blockchain and what is big data
1. Blockchain: It is a new type of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Application mode. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Blockchain is an important concept of Bitcoin, mentioned in the "2014-2016 Global Bitcoin Development Research Report" released by the Internet Finance Laboratory of Tsinghua University PBC School of Finance and Sina Technology. Blockchain is the underlying technology and infrastructure of Bitcoin [2]. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
2. Big data: refers to a collection of data that cannot be captured, managed and processed with conventional software tools within a certain time range. It requires new processing models to have stronger decision-making power, insight discovery and process optimization capabilities. massive, high-growth and diversified information assets.
The concept of blockchain is so popular! Will blockchain technology become a new trend?
In recent years, the development ecosystem of blockchain has gradually been improved and enriched. Industry insiders believe that with national policy support, widespread attention and financial support, blockchain technology can achieve gradual and stable progress. Although the upside prospects of blockchain technology are broad, we must remain calm about this.
What is the relationship between blockchain and big data? Will blockchain replace big data? The relationship between blockchain and big data is not very big. Big data is mainly about managing massive amounts of data, and the core of blockchain is to achieve high security and reliability of data without centralized intermediaries. Jinwowo Network Technology
Therefore, blockchain and big data do not conflict with each other, nor will they replace them. They are completely different solutions for data in different scenarios.
⑷ What is ETC/Ethereum Classic
A brief history of Ethereum Classic (ETC)
Ethereum Classic began with an unfortunate event.
In May 2016, the Decentralized Autonomous Organization (DAO) held a token sale with the goal of establishing a blockchain-based venture to fund future decentralized applications (DApps) within the Ethereum ecosystem.
Basically, a DAO is a complex smart contract that operates in a decentralized manner – computer code that automatically executes tasks between multiple parties when conditions are met.
Despite its ambitious goals and successful token sale, the DAO's code contained a major vulnerability that allowed attackers to steal ETH from decentralized organizations.
An attacker exploited this vulnerability to trigger the infamous DAO hacking incident in June 2016, maliciously stealing approximately $50 million worth of ETH.
There is no doubt that the DAO hacking incident shocked the Ethereum community and caused the price of ETH to fall from US$20 to US$13.
After the DAO hack, the Ethereum community had to choose from three options.
Do nothing and suffer the consequences of the attack; or
Initiate a soft fork and recover funds; or
Deploy a hard fork to Recover lost ETH.
Both soft forks and hard forks are major network upgrades. However, a soft fork allows non-upgraded users and upgraded users to communicate with each other, while a hard fork is not backwards compatible with previous versions.
As developers realized that deploying a soft fork would expose the network to distributed denial of service (DDoS) attacks, the Ethereum community decided to launch a hard fork to recover funds lost in the DAO hack.
Although this plan is supported by the majority of people, a small group of people in the Ethereum community are opposed. They believe that "code is law" and the blockchain network should be immutable. .
The failure of both parties to agree on a solution eventually led to the split of the Ethereum blockchain.
Those trying to recover their lost ETH opted for a hard fork, starting the Ethereum (ETH) blockchain we know today, while another group stayed with the original Ethereum Classic ( ETC) chain.
What problems does Ethereum Classic solve?
Ethereum Classic (ETC) is a blockchain platform that allows developers to deploy smart contracts and DApps.
While this functionality is identical to that of Ethereum (ETH), there are two main differences with the ETC blockchain.
First of all, the Ethereum Classic community opposes tampering with distributed ledgers and supports the view that "blockchain networks cannot and should not be modified."
Secondly, although there is no hard upper limit on the total supply of ETH, Ethereum Classic adopts a constant supply monetary policy.A maximum of 230 million ETCs are allowed to be created.
As a plus, Ethereum Classic launched the Atlantis hard fork last year to increase interactivity with Ethereum and improve the privacy protection of transactions through zk-SNARKS.
Recommended trading platforms for Ethereum Classic ETC
Huobi, OKEX, AAX, etc.
⑸ What are the three major public chains of blockchain?
Public chain, the abbreviation of public chain, means that anyone in the world can read it, anyone can send transactions and transactions can Obtain valid confirmation of a blockchain in which anyone can participate in the consensus process.
1. The top three public chains in the world
BTC, ETH, and EOS (by market capitalization) are three heavyweight products, representing Blockchain 1.0, Blockchain 2.0 and Blockchain 3.0 respectively. Three stage.
1. Bitcoin BTC (Blockchain 1.0)
Bitcoin has emerged as a new type of digital currency and global payment network since its birth in 2009. BTC is also the most successful and mature application of blockchain. , now in many situations, BTC is much more famous than blockchain.
2. Ethereum ETH (Blockchain 2.0)
In layman’s terms, Ethereum is an open source platform digital currency and blockchain platform that provides developers with a platform to build and publish applications on the blockchain. . Ethereum can program, decentralize, guarantee, trade anything, vote domain names, financial exchanges, crowdfunding, company management contracts and most agreements, intellectual property, and hardware-integrated smart assets, etc.
3. Yuzu EOS (Blockchain 3.0)
EOS appears as an enterprise-level blockchain operating system based on Bitcoin and Ethereum, which is easier to use and more powerful than the former. EOS provides all application developers with many functions such as database account permission settings, execution scheduling authentication, and network communication.
2. The world's three major exchange public chains: Huobi Chain, Binance Chain, and OKEx Chain OKChain
1. Developed by Huobi Chain, the world's largest trading platform, Huobi Chain is An independently innovative supervised blockchain operating system for the financial field, based on blockchain global asset digitization and financial market infrastructure. At the same time, based on the consideration of injecting the long-term value of HT into a unified value carrier, HT will serve as the only underlying token of the Huobi public chain.
2. Developed by Binance, the world's second largest trading platform, Binance Chain started early in application and is currently mainly circulated on DEX and asset chains. Binance Chain is a digital asset creation and exchange platform, with BNB as the main chain token
3. Developed by OKEx, the world's third largest trading platform, OKChain is more scalable, has high transaction processing capabilities and smart contracts.About the platform, OKChain is developed based on Cosmos-SDK, and the consensus uses DPOS. OKB is the underlying token of the OKEx ecosystem.
⑹ What is the abbreviation of TX for blockchain
It is undeniable that the future of blockchain is promising, but individual investors still need to think carefully if they want to invest. Use your own discretion. If you don't have enough capital, it's better not to enter the market easily.
⑺ What does XEM mean?
Introduction: New Economic Movement - New Economy Movement, referred to as NEM, was founded on January 19, 2014. The founder is a mysterious person on the Bitcointalk.org forum named Utopianfuture. The original intention of Utopianfuture was just to build a copy of the second-generation digital currency NXT. He later realized that NXT's distribution model was unreasonable, so he joined NEM, which had an egalitarian distribution model.
Release time: Released in 2015. XEM is the code name for the currency issued by the NEM (New Economy Movement) New Economic Movement organization.
Circulation supply: 8,999,999,999XEM
Current total circulation: all in circulation
Market value: $5,299,019,999
⑻ What does ICO mean
p>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 common digital currencies such as Bitcoin and Ethereum. The behavior of money.
ICO is a blockchain industry term and a common way to raise funds for cryptocurrency/blockchain projects, in which early participants can receive initially generated cryptocurrency in return.
Because the tokens have market value, they can be exchanged for legal tender, thus supporting the development costs of the project. The tokens issued by ICO can be based on different blockchains. Common ones are issued based on the Ethereum (ETH) and BitShares (BTS) blockchains, with the blockchain providing accounting services and value consensus to achieve global issuance and circulation.
(8) Blockchain project abbreviation Extended reading:
The connection and difference between ICO and IPO.
IPO (English abbreviation Initial Public Offering) refers to the issuance method of a joint-stock company to the public for the first time. Compared with ICO, they have similarities and differences.
What they have in common
1. All raise funds by selling shares;
2. All potential investors take risks for the potential huge gains.
Differences
1. Most of the supporters of ICO are projectsEnthusiasts or unprofessional investors;
2. ICO does not require a registered operating license;
3. The ICO platform is a third-party neutral platform, and investors bear their own risks.
The development history of ICO:
July 2013: Mastercoin (now renamed OMNI) is one of the earliest blockchain projects to conduct ICO. It was once discussed on the Bitcointalk forum Crowdfunding successfully raised 5,000 BTC. Mastercoin is a second-generation coin built on top of the Bitcoin protocol and is designed to help users create and trade cryptocurrencies and other types of smart contracts.
December 2013: NXT (Future Coin) is the first complete POS blockchain. It raised 21 BTC (equivalent to US$6,000 at the time). Its market value was once as high as US$100 million. For investors, It is undoubtedly one of the most successful ICO projects.
Between 2013 and 2014: Many crazy blockchain projects successfully launched ICOs, and their token prices have skyrocketed. Unfortunately, these ICO projects eventually died due to hype. In the process or directly become a scam. However, during this time, there were also very successful ICO projects, such as Ethereum.
July 2014: Ethereum (Ethereum ETH) has high popularity at home and abroad. It is one of the largest ICOs to date, raising more than 18 million US dollars. It is also the cryptocurrency with the highest market value after Bitcoin. Digital currency.
March 2015: Factom (Factom) used the blockchain technology of Bitcoin to innovate the data management and data recording methods of commercial society and government departments through the Koinify platform ICO.
