① What is blockchain and how to make money with blockchain

Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
The ways to make money in the blockchain are as follows:
1. Coin speculation. Coin speculation is like stock speculation. Coin speculation is the lowest threshold for making money in the blockchain;
2. Vendors, district Blockchain is a global market. Like small traders, you can move from a low-price platform to a high-price platform to sell and earn the difference;
3. Earn commissions for promotion. The blockchain method is to register first Exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you can get a commission;
4. Mining, "mining" in Bitcoin is The accounting process;
5. Technical support, providing blockchain technical support to some teams and enterprises;
6. Opening a trading website and charging handling fees;
7. Developing wallets and wallets It is the infrastructure of the blockchain, just like the "Alipay" or "WeChat Pay" of the blockchain;
8. Be a blockchain project or infrastructure equipment supplier.

② Who is paying attention to IPFS in this field? Good company

The best in the IPFS field should be the Interstellar Alliance Company, and the price is very affordable. At present, there are too many companies selling IPFS mining machines in China, 300-500 or more. Currently there are only a few companies in the first tier. The Star Alliance is among them.

PFSUnion Interstellar Alliance (referred to as Interstellar Alliance) is headquartered in the magical city of Shanghai. The team is composed of key members from Internet giants such as Microsoft, AMD, Alibaba, Tencent, SAP, Huawei, Shanda, Inventec, etc. It has a mature and complete industrial supply chain, as well as multiple branches and partners at home and abroad.

Since its establishment, the Interstellar Alliance has been backed by technology and focused on the research and development of blockchain technology, focusing on IPFS-Filecoin builds a global IPFS ecosystem, providing mining machines, mining farms, hosting, data, applications, knowledge, and marketing services.

Interstellar Alliance has four major advantages over other companies:

1. Low price and high cost performance.

2. The highest marketing commission in the same industry.

3. Interstellar Alliance ranks first in block production rate and computing power growth rate.

4. Long-term strategic planning, with five major development strategies: mining machines, mining pools, mines, applications, and chips.

(2) Extended reading on what Blockchain House is:

To evaluate the quality of a service provider, we should look at these aspects Let’s take a look:

1. Check whether the company’s genetic founder team was born in R&D or marketing. If they are all R&D teams, and each person has more than 10 years of experience, both blockchain development experience and server operation and maintenance experience, the overall team will exceed 50 people.

2. As the official launch of the mainnet approaches, the layout has begun. First of all, you must choose a technology-based mining machine hosting company to cooperate with, because once the mainnet is online, the strength of each technical team will determine whether you can grab more orders faster and whether you can mine more than others. Coin, whether it is cloud computing power or physical hosting, the hard disks that are currently doing relatively well are almost all from Seagate. Overall, ipfs technology is revolutionary.

③ What exactly is blockchain and what it can do? Let me explain it in layman’s terms~Thank you

1. Blockchain is distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. and other new application models of computer technology.

Blockchain is an important concept of Bitcoin. It is essentially a disintermediated database. As the underlying technology of Bitcoin, it is a series of related cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

2. Application

1. Art industry

Ascribe allows artists to use blockchain technology to declare ownership and issue numberable, limited editions. Works can be for any type of artwork in digital form. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.

2. Legal industry

BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property. Interestingly, BitProof recently cooperated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how to make diplomas and academic certificatesHow to handle and use birth certificates.

3. Development industry

Colu is the first company to allow other companies to issue digital assets. Their ability to "tokenize" various assets has impressed many people. While the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu's tokens can be configured in various states and types, be able to leave and return to the system, and When storing data on the blockchain is too large, the data can be stored on the BitTorrent network.

4. Real estate industry

They plan to modernize the entire industry chain process and solve various problems faced by everyone involved in real estate, including the naming process, land registration, Agency intermediaries, etc.

5. Internet of Things

A possible application scenario is: generate corresponding behavior through Transaction, assign an address to each device, and inject a certain fee into the address. Perform relevant actions to achieve Internet of Things applications. Similar to: PM2.5 monitoring point data acquisition, server leasing, web camera data calling, DNS server, etc.

6. Insurance industry

In the past two years, the hottest topic in the technology field must be inseparable from blockchain technology. This underlying technology, which was born out of Bitcoin, has proven its highly secure and reliable architecture and algorithm design with more than 7 years of stable operation. At the same time, it has relied on innovative technologies such as distributed ledgers and smart contracts to upgrade industries in many industries. It opens up a huge space for imagination. Some industry experts even predict that blockchain technology will set off a second Internet revolution.

(3) Extended reading on what Blockchain House is:

In 2008, Satoshi Nakamoto wrote in the "Bitcoin White Paper" Proposed the concept of "blockchain", founded the Bitcoin network in 2009, and developed the first block, the "genesis block".

The blockchain shared value system was first imitated by many cryptocurrencies, and improvements were made in proof-of-work and algorithms, such as the use of proof-of-stake and SCrypt algorithms. Subsequently, the blockchain ecosystem continued to evolve around the world, with the emergence of initial coin offerings (ICOs), smart contract blockchain Ethereum, asset tokenized sharing economies with “light ownership, heavy usage rights”, and blockchain countries.

Currently, people are using this shared value system to develop decentralized computer programs (Decentralized applications, Dapp) in all walks of life, and build decentralized autonomous organizations and decentralized autonomous communities around the world. (Decentralized autonomous society, DAS).

④ How to explain blockchain in a popular way

Blockchain isIt is a decentralized distributed ledger database. The advantage of this distributed ledger is that buyers and sellers can trade directly without any intermediary. Everyone has a backup, even if your copy is lost, it will not be affected.

(4) Extended reading on what Blockchain House is for:

Blockchain application fields

1. Financial field

Blockchain has potential 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.

2. Internet of Things and Logistics Fields

Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.

3. Public welfare field

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

4. Insurance field

In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims.

⑤ What does blockchain do?

Blockchain is a kind of distributed data storage, point-to-point transmission, consensus mechanism, encryption New application models of computer technology such as algorithms.

Blockchain is also a decentralized distributed ledger system that can be used to register and issue digital assets, property rights certificates, points, etc., and conduct transfers, payments and transactions in a point-to-point manner. Compared with traditional centralized ledger systems, the blockchain system has the advantages of being completely open, non-tamperable, preventing multiple payments, and does not rely on any trusted third party.

In other words, the previous computing model required a computer to perform all calculations to draw conclusions, while the technical application of blockchain is to use "distribution" to transfer a complex operation separately. Giving N multiple computers to perform simultaneous operations not only reduces the storage load of each computer, but also saves time. Finally, all results are integrated through the "consensus mechanism" to obtain the final result.
