Ⅰ What is the connection between blockchain and equity crowdfunding

Now let’s talk about the feasibility of blockchain equity crowdfunding in China. We all know that as far as China is concerned, companies are divided into two broad categories: joint-stock companies and limited companies.
Joint-stock companies are divided into "listed companies" and "unlisted joint-stock companies". The shares of a listed company are registered with the China Securities Depository and Clearing Corporation, so its issuance of shares or share transactions are subject to the management regulations of the China Securities Regulatory Bureau. We won’t go into details here; shares issued by non-listed joint-stock companies do not need to be registered by any institution, and rights can be confirmed by issuing shares themselves and maintaining a shareholder register. Of course, many of them register through third-party institutions such as the industrial and commercial departments or China Securities Depository and Clearing Corporation, using local share custody centers to provide third-party registration services for public announcements. Moreover, when the company's equity changes, it needs to be registered through Manual processing of paper equity certificates, option issuances and convertible notes will make the maintenance of shareholder registers very complex and cumbersome, and the tracking and maintenance of transactions will become more difficult to trace as the number of transactions increases.
If you use Techshares blockchain technology for equity crowdfunding, it will perfectly solve all the above problems. The blockchain ledger is safe and transparent, cannot be tampered with, and is easy to track. It can record the company's equity and its changes at any time. history.
Convenient equity transfer and circulation
For equity crowdfunding, equity circulation is an important part of the business, which can stimulate user activity and promote more registration and issuance. Traditional OTC over-the-counter equity transactions are based on the credit of both parties to the transaction. The parties to the transaction bear the credit risks themselves. Transactions can only proceed after establishing bilateral credit lines. The trading platform collectively bears the credit risks of market traders.
Techshares blockchain technology can reduce the credit risk of transactions. It essentially decentralizes the third party that provides credibility, that is, it is no longer limited to specific third-party entities, but relies on All participants come together to maintain a registration system. From the perspective of the functions achieved, the blockchain, on the one hand, hands over the rights to record to the company itself, embodying the spirit of autonomy; on the other hand, it can also ensure the openness, transparency and authenticity of information records, minimizing rights disputes. change. The ownership of equity is registered in the blockchain, and equity transactions must be signed by the owner's private key to be verified; after the transaction is confirmed, changes in equity will also be recorded in the blockchain, thus protecting the interests of both parties to the transaction.
How to ensure safety
As an investor, the most worrying issue is the security of funds. Traditional equity crowdfunding often may cause "double spending" problems (note: double spending - double spending, That is, the only share is transferred repeatedly to two people), until the central clearing agency ensures that the entire system can balance the accounts after the transaction is fully digitalized. However, the risks are often borne by the platform, and the equity crowdfunding business is different from the traditional market.Internal trading is different. It is carried out by many independently operated companies, so these trading activities are scattered across various platforms. After using the Techshares blockchain technology, the decentralized trust built by the blockchain is not based on human will. It can also ensure the normal operation of the system and business without the need for mutual trust. Everyone becomes a node in the blockchain, has their own public and private keys, and jointly participates in rapid transaction verification and accounting. Furthermore, in the early stages of equity crowdfunding, many parties, including the sponsor, crowdfunding platform, lead investors, sponsors, etc., jointly sign a crowdfunding contract to stipulate their respective responsibilities and obligations. This contract can be converted into a smart contract and stored in the blockchain, and the blockchain ensures that the contract cannot be tampered with during execution. In this way, there is no need to worry about safe space.
Strongly scalable, reasonable and legal
Blockchain equity crowdfunding consists of a three-layer structure. The bottom layer is the blockchain network, which builds a decentralized and trusted distributed ledger; The middle layer combines business logic with the blockchain to jointly establish account center, equity registration, equity certificates, equity transactions, equity management and other functions; the top layer is a crowdfunding platform for customer-oriented services, and the business of the platform is theoretically It can be infinitely extended to various fields and industries.
The use of TechShares' blockchain technology enables decentralized trust (Decentralized trust) by building a P2P self-organizing network, a time-ordered and tamper-proof cryptographic ledger, and a distributed consensus mechanism. In addition, neither the Company Law, the Company Registration Regulations nor other laws and regulations impose any specific restrictions on the form of the shareholder register maintained by the company itself. A company may choose to create and maintain a shareholder register in any documented form, and is not limited to a specific medium. Therefore, it is completely legal to use TechShares as a carrier to conduct equity crowdfunding on the blockchain. Once chosen voluntarily by the company, it can provide legally valid proof of the company's equity (shares).

Ⅱ In the 3.0 era of blockchain, how to play the blockchain app

If Bitcoin represents the blockchain version 1.0, it proves to the world that digital currency can be realized . Then Ethereum represents the 2.0 version of the blockchain, letting everyone know more about how to play the blockchain, decentralized applications and smart contracts. In 2018, blockchain will enter the 3.0 stage. Applications and scenarios will be the core of blockchain. Applications based on blockchain will spring up in various industries. This will be the last stage of blockchain development. early bonus period. The demand for talents driven by the application of blockchain technology has been increasing. Blockchain technology talents have become an upstart profession, highly competitive, and also have enviable high salaries.

More and more large companies are entering the blockchain industry, and Dufeng Huanlv strives to become the "leader" in this emerging field.Among them, Alibaba, SF Express, JD.com, etc. have all hired technical talents in the blockchain field with high salaries. In this information age with the Internet as the core, the competition among large companies is ultimately the competition for talents. Especially when the emerging blockchain technology is first emerging, blockchain technology talents are “in hot demand” whether at home or abroad. As a "young" technology, the main force for future development is bound to be young people. However, many current practitioners in the blockchain industry are self-taught and have no systematic professional knowledge training, or are just cryptography, programming, and the Internet. Technical and other unilateral talents. Blockchain technology values ​​​​more complex talents with multiple technologies. In the future, with the maturity of the application of blockchain technology, talented people will become more popular to "recharge" themselves and devote themselves to the blockchain. Be prepared for the heat. In addition to participating in blockchain development work, what else can help you catch up with the blockchain train? Investing in blockchain projects is obviously another approach. So how to judge whether a project is a real blockchain or a fake blockchain?

Is the cost of confirming the authenticity of information in this field very high? For example, there is a Christian coin project, which uses the blockchain to record the time people read the Bible, and then issues Christian coins to these people. Let’s not discuss it for now. Is it meaningful to count the time people spend reading the Bible? Even if it is meaningful, this can be solved using other models. For example, when checking in in a WeChat QQ group, why should we develop a blockchain smart contract and imitate the blockchain? I'm afraid I'm just cutting leeks to keep warm. So what are the areas where it is difficult to confirm the authenticity of information? The most typical one is finance. There is a large amount of information asymmetry in financial markets, which makes the market full of uncertainty. For example, when transferring money, you won't know until the bank tells you that it has arrived. Now blockchain technology can solve such problems better and faster. Similar information confirmation issues such as market data, credit, contracts, etc.

Whether a meaningful large-scale consensus is formed: One of the outstanding advantages of the blockchain is that it can effectively form a large-scale consensus through public ledger accounting and notification to the entire network. Nowadays, for many projects, there is no need to form a network-wide consensus. Some are just for crowdfunding and issuing tokens. The blockchain consensus of the project is meaningless. Does this model have a network effect? ​​The network effect means that a project will become more valuable as the number of project users increases, because the value of the project does not lie in the users themselves, but in the connection network between users. Bitcoin is a classic example. The more user nodes there are, the links between nodes will grow exponentially, and the entire Bitcoin ecosystem will be more valuable.

Of course, in addition to these points, there are many basic principles for judging projects, such as effective incentive mechanisms, strong teams, project solutions to pain points, etc.

III What are the applications of blockchain

1. Blockchain + product traceability
This year’s Tmall Double 11. Ant Blockchain used blockchain for the first time to trace the origin of 160 million commodities.
JD.com and 7FRESH use blockchain to ensure waterImprove vegetable quality.
Carrefour’s blockchain product Guanxi Honey Pomelo is launched.
2. Blockchain + Electronic Invoice
The Shenzhen Taxation Bureau of the State Administration of Taxation has opened up the WeChat payment platform and launched the "WeChat payment blockchain electronic invoice" function. In October this year, WeChat Pay electronic blockchain invoices were used on a trial basis at some merchants in Shenzhen. The official launch this time means that all merchants in Shenzhen who have opened WeChat Pay can log in to their own WeChat Pay merchant platform to directly activate the blockchain electronic invoice function.
3. Blockchain + Law
The judicial blockchain of the Internet Court is online, and the electronic evidence stored on the chain has legal effect. The Hangzhou court used blockchain to adopt key evidence, which was used by a technology company in Shenzhen on its website. The technology company then became the defendant.
4. Blockchain + Content

The first exemplary vertical content social DAPP based on the Ulord public chain. It is the world's first decentralized experience value based on the ulord public chain. The sharing platform allows users to receive corresponding rewards while creating, sharing, and disseminating experience value, stimulating value re-creation and forming a virtuous cycle of content ecology.
5. Blockchain + Insurance
Ant Financial announced the first mutual aid case of the online mutual aid program "Huang Bao". A 5-year-old girl from Shanghai received a serious illness mutual aid fund of 300,000 yuan. For all For participants, each person shared an average of 0.03 yuan. In addition to case details, in order to ensure information openness and transparency, the public notice also issued medical diagnosis certificates, discharge summaries, surgical records and other information, and stored the data on the blockchain.
6. Blockchain + Health
The health energy chain based on the Ulord public chain is currently in internal testing.
7. Blockchain + Intelligent Manufacturing
Blockchain + Intelligent Manufacturing Well-known domestic and foreign companies such as Alibaba, JD.com, and IBM have begun to get involved in the blockchain + intelligent manufacturing business. IBM cooperated with Blue Ocean Camel to build a blockchain + foreign trade supply chain intelligent platform, Alibaba Cloud launched its own enterprise-level blockchain service BaaS (Blockchain as a Service), JD.com’s blockchain service platform Zhizhen Chain, etc.

IV What are the better equity crowdfunding platforms in China

The well-known domestic crowdfunding platforms are as follows:
Taobao Crowdfunding and JD Crowdfunding: backed by the largest domestic crowdfunding platforms The e-commerce platform has guaranteed traffic and high popularity and recognition, but it is often criticized as a sales place for goods.
Biying China: It is the first to introduce blockchain into the crowdfunding industry in China. After the crowdfunding project of the platform is successful, the platform will issue corresponding digital currencies as certificates of assets. These digital currencies can be used in the market For free trading, there will be fixed dividends.

IV Is the risk of a blockchain crowdfunding platform like ico365 high? How is it different from traditional crowdfunding platforms?

Any crowdfunding project has a very high risk rateHigh investment product.
Blockchain project crowdfunding platforms are essentially the same as traditional equity crowdfunding platforms.
It can be said that blockchain project crowdfunding is a subcategory of equity crowdfunding.
Equity crowdfunding is subject to legal and regulatory restrictions, with restrictions on the number of investors and the amount of investment. Investors also need to undergo investment review. The cost and threshold for ordinary people to participate are relatively high, and the target group is high-net-worth individuals.
Equity crowdfunding has poor liquidity, and it often takes a long time to exit, and even most of the investment in projects seems to be in vain.
Blockchain crowdfunding is a bit similar to universal crowdfunding, because its crowdfunding funds are settled in Bitcoin and are not regulated by laws and regulations. Therefore, there are no excessive requirements on the number of people and investment amount. The investment cost is low but the threshold is relatively high.
Since blockchain projects are based on the underlying technology of Bitcoin, it is difficult for ordinary people to understand it. In fact, it can simply be regarded as a technical method of distributed collaborative work.
There are relatively few successful blockchain projects in the market, so there is no unified reference standard, and projects are completely dependent on personal judgment. Settlement is done in Bitcoin, so if you need to participate, the requirement itself is to accept the high-risk threshold of digital currencies. (There are many projects that cheat money)
Blockchain crowdfunding has good liquidity. Basically, after the so-called "tokens" appear, you can completely withdraw from the transaction. The risk of fluctuation is also very high.
Of course, as a technology being studied by the central bank, blockchain projects deserve attention, but caution is also required. As for the ico365 platform, it is recommended that individuals make their own decisions. The new platform has no reference basis for evaluation.

VI Which projects are really using blockchain technology in the financial industry

The current application of blockchain is still in its infancy, and the current application of EOS games is still relatively good. The Ripple protocol has been applied in bank settlement.

VII What is the significance of Xunlei Investment Company’s launch of distributed blockchain storage products?

According to news on January 23, Beijing Yunhui Tianxia Technology Co., Ltd. launched the blockchain storage “My Home Cloud” "Recently launched crowdfunding on JD.com, with a crowdfunding price of 1,499 yuan. As of 11 a.m. today, the total amount of crowdfunding has exceeded 6 million.

Many companies are currently using blockchain to motivate users. Blockchain can be split into two parts: one is a point-to-point decentralized electronic accounting system; the other is the incentive mechanism used to maintain this system. Digital currencies such as Bitcoin, Litecoin, and Ethereum are all products of the incentive mechanism in blockchain technology. Xunlei Vanke Cloud, Baofeng Broadcasting Cloud and Jirou are all exploring this incentive system.

Ⅸ What are the classifications and applications of blockchain projects

From the current mainstream blockchain projects, blockchain projects mainly fall into four categories: Category 1: Coin Category; second category: platform category; third category: application category; fourth category: asset tokenization.

Coins mainly serve as the "medium of exchange" in the field of blockchain assets. The medium of exchange refers to general equivalents, such as gold and silver notes in the past. (Trade blockchain assets on "Bihui Exchange")

Platform projects refer to the establishment of technology platforms to meet the development of various blockchain applications, which can reduce the cost of developing applications on the blockchain. threshold.

The scope of application projects is relatively wide, covering many fields such as finance, social networking, games, property rights protection, etc. It is also the fastest growing field of blockchain assets.

The asset tokenization project refers to the blockchain mapping of physical assets, that is, the physical assets are put on the chain. Currently, there are no more than 10 varieties.

01 Currency

The first category is currency projects, which are also the earliest blockchain projects. Currency projects mainly include Bitcoin and Litecoin, etc.Head. In addition, there is another type of asset that has the characteristics of anonymity. Its main functions include realizing payment while protecting the privacy of both parties. The well-known ones include Dash, Monero and Big Zero that use zero-knowledge proof. Coin (Zcash), etc. Currency mainly serves as the "medium of exchange" in the blockchain asset field. The medium of exchange is the general equivalent that you use to exchange for goods. For example, in the past, gold, silver, and banknotes could be used as media of exchange. There are currently more than 2,100 types of digital assets in the world, and the number of currency blockchain projects has grown rapidly recently. As of June 2018, Bitcoin still has the largest market value.

02 Platform Category

The second category is platform blockchain projects. The main function of platform blockchain projects is to establish a technology platform to meet the needs of various blockchain application development. The required technical requirements; simply put, platform applications allow developers to directly issue digital assets on the blockchain, write smart contracts, etc. A smart contract is a computer program that runs on a blockchain database and can be automatically executed under conditions set by its source code.

For example, if you develop a smart contract based on a house rental agreement on the blockchain, when the owner receives the rent, it will trigger automatic execution and give the apartment's security key to the tenant.

The main function of platform blockchain projects is to establish an underlying technology platform to allow developers to develop applications on the underlying technology platform. A considerable number of platforms are still under development. As of June 2018 , the one with the largest market value is Ethereum.

03 Application Category

The third category is application blockchain projects. Application projects are developed based on blockchain development platforms (such as Ethereum) and can solve various problems in the real economy. Blockchain projects that address many issues in the field.

For example, the blockchain-based prediction platform Augur, the blockchain-based computing power trading platform Golem, the blockchain-based luxury traceability platform VeChain, and the blockchain-based asset exchange and transfer services OmiseGo. Using blockchain technology, these projects can better solve trust issues, cross-border circulation and other issues. At the same time, using smart contracts and tokens on the blockchain, automatic execution can be better realized, greatly improving the efficiency of social and economic activities. efficiency. The scope of applied blockchain projects is relatively wide, covering many fields such as finance, social networking, games, property rights protection, etc. It is also the field where the market value of blockchain projects is increasing the fastest.

04 Asset Tokenization

The fourth category is asset tokenization blockchain projects. Asset tokenization refers to linking blockchain assets to physical assets such as gold and U.S. dollars. , is a blockchain mapping of physical assets. As of February 2018, there are no more than 10 varieties. The more typical representatives are USDT, which is benchmarked against the US dollar, and Digix Dao, which is benchmarked against gold. Each DigixDAO token represents 1 gram of London gold. Silver Market Association certified gold. Asset tokenization has the advantages of convenient transactions and safekeeping. First, assetsTokenization makes transactions easier. Because blockchain assets can be split, they have better liquidity.

For example, currently the real estate needs to be transferred as a whole. If the real estate can be tokenized, it can be purchased in pieces, making transactions more convenient. Secondly, tokenization of physical assets is more conducive to safekeeping. In physical transactions such as gold, it is easy to cause wear and tear and cause losses. However, after tokenization of physical assets, there is no need for physical transfer, which is more conducive to the custody of physical assets.
