Blockchain in crowdfunding
If you want to understand the application of blockchain, you can refer to many books and opinions, such as illustrated blockchain, blockchain: reshaping the economy and the world, blueprint and guide of new economy, and articles of coin'an community, including a detailed understanding of the platform of coin'an community, with great strength
As the name suggests, blockchain is composed of block and chain. It is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on. It is a kind of chain data structure that combines data blocks in order according to the time sequence, and it is a secure and reliable distributed account book that can not be tampered with and forged by means of cryptographyin 2008, in his paper bitcoin: a peer-to-peer e-cash system published by Nakamoto, he first proposed the idea of blockchain and encrypted digital currency. Starting from bitcoin, blockchain has become the underlying technology of various digital currencies
Second, the working principle of blockchain:1. The basic concepts include: (1) transaction: one operation will change the account status once, such as adding a record 2) Block: records the transaction and status data within a specified time, which is a consensus and preservation of the current account status 3) Chain: it is composed of a series of blocks in chronological order, which is the log record of the whole state change. If you understand the working concept of blockchain, it is not difficult to understand its working principle. Suppose there is a distributed data logbook, which can only be added, not deleted or changed. Its structure is a linear chain formed by a series of "blocks" (which is also the source of the name of "blockchain"), and new data must be put into a new block to be added, The maintenance node can propose a new block, but it must go through a certain consensus mechanism to reach an agreement on the final selected block
2. Take bitcoin as an example to see the working principle of blockchain
the block of bitcoin is divided into block head and block body
Core advantages and characteristics of blockchain1. The verification, accounting, storage, maintenance and transmission of decentralized blockchain data are all based on distributed system structure. There is no centralized hardware or management organization, and the rights and obligations of any node are equal, The data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system. 2. The open and transparent system is open. In addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent. 3. Security blockchain uses consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work. 4. Information cannot be tampered with. Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% (almost impossible) nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid. Therefore, the data stability and reliability of the blockchain are extremely high. 5. Anonymity because the exchange between nodes follows a fixed algorithm, and its data interaction does not need trust (the program rules in the blockchain will judge whether the activity is effective or not). Therefore, the counterparties do not need to let the counterparties generate their own trust by disclosing their identities, which is very helpful for credit accumulation
At present, the most popular classification of blockchain is to divide blockchain into public blockchain, private blockchain and consortium blockchain according to different participants1. Public chain: anyone can participate in the use and maintenance, and can obtain the effective confirmation of the blockchain. Public chain is the earliest blockchain and the most widely used blockchain at present, such as bitcoin blockchain. The information is completely public
if the licensing mechanism is introced, it includes private chain and alliance chain. 2. Private chain: a company or indivial only uses the blockchain technology, enjoys the exclusive write permission of the blockchain, and does not disclose the information. At present, conservative giants (traditional finance) want to experiment with private blockchain, and the application procts of private blockchain are still groping. 3. Alliance chain: it is a blockchain between the public chain and the existing chain, which is jointly controlled by multiple organizations. The use of the chain is managed with authority, which can be controlled by the manager, and also open to others according to the manager's wishes. In addition, according to the different use scenarios and purposes of blockchain, it can be divided into currency chain for the purpose of digital currency, property chain for the purpose of recording property rights, and crowdfunding chain for the purpose of crowdfunding
On May 28, Ma Huateng, CEO of Tencent, proposed the anti-counterfeiting method based on cloud integrated blockchain technology, which is far more efficient than traditional anti-counterfeiting methods. The future anti-counterfeiting verification scenario may only require users to use their mobile phones for simple scanning, and a large number of complete information based on different dimensions can be obtainedtake Maotai liquor as an example:
distillery address, proction workshop, operation staff, inspector, delivery time, transportation vehicle information and driver information,
liquor year, raw material source, raw material supplier, storage warehouse number, raw material transportation vehicle and driver information,
all information can be accurately traced, permanently recorded and tampered with
the above information can be easily verified
2. Food safety issues as early as last November, Wal Mart has cooperated with IBM to track the source of food by using blockchain technology, so as to ensure the safety of food and increase the circulation of food to rece costs. For Wal Mart and other large supermarkets, it took a few days to investigate the source of problem food, After using this technology, only one item of proct information is needed to achieve accurate traceability, and important information such as food origin, inspector, supplier, logistics and transportation can quickly find problems in a few minutes. Currently, procts tracked by blockchain include packaging procts from the United States and pork from China
3. Information security
blockchain technology is promoting an information security technology revolution. (1) identity protection PKI is a common public key encryption technology in e-mail, message application, website and other communication applications. However, since the implementation of most PKI, the centralized trusted third party certification authority (CA) is used to issue, activate and store user certificates. Hackers can attack PKI to fake user identity or crack encrypted information
certcoin is the first PKI implementation of blockchain, which comes from MIT, removes the centralized authentication center, and uses blockchain as a distributed ledger for domain name and public key
pomcor company: blockchain PKI implementation path: keep the authentication center, and use blockchain to store the hash value of issued and activated certificates. Users can verify the authenticity of certificates through decentralized and transparent sources, and can also improve the network access performance through local authentication of secret key and signature based on blockchain
(2) data integrity protection
guardtime developed a secret key free signature architecture (Ksi) based on blockchain technology to replace the secret key based data authentication technology. Ksi stores the hash table of the original data and files on the blockchain, runs the hash algorithm to verify other copies, and compares the results with the data stored in the blockchain. Any data tampering will be found quickly because the original hash table is stored in millions of nodes
(3) key infrastructure protection
the "Achilles heel" of the Internet, DDoS has entered the TB era, DDoS is still the simplest weapon for hackers to bring down the big target with low cost, DNS service is the primary target for hackers to carry out large-scale destruction, but blockchain technology is expected to fundamentally solve the problem
The distributed storage ofblockchain makes hacker attacks lose focus. Nebulis is developing a distributed DNS system, which uses Ethereum blockchain and interstellar Internet file system (IPFs, the distributed substitute of HTTP) to register and resolve domain names. The biggest weakness of DNS is caching, which makes DDoS attacks possible. It is also the bane of the centralized government's censorship of social networks and manipulation of DNS registration. A highly transparent and distributed DNS system can effectively prevent any entity, including the government, from arbitrarily manipulating records
(1) digital currency: improve the convenience of currency issuance and use, such as bitcoin and Ethernet in foreign countries, and guorenbao in Chinafrom the use of physical transactions, to physical currency and credit currency, and then to the rise of bitcoin network, more and more people are aware of the distributed ledger blockchain technology behind it, and graally apply it in many scenarios other than digital currency
(2) cross border payment and settlement: realize point-to-point transaction, rece intermediate fees
transfer and payment. At present, the most mature application of blockchain technology is payment and transfer. Blockchain technology can avoid complicated systems, save the process of inter-bank reconciliation and review, and accelerate the settlement speed; Virtual currency can rece transaction costs without the intervention of clearing house. Different countries have different clearing proceres. It takes two or three days for a single remittance to arrive, which is inefficient and accounts for a large proportion of funds in transit. No longer through the third party, through the blockchain technology to form point-to-point payment. By eliminating the link of the third-party institutions, we can make full day payment, real-time payment, withdraw cash quickly and rece the hidden cost, which helps to avoid the capital risk. It is timely and convenient
(3) bills and supply chain financial business: rece human intervention, rece costs and operational risksvalue transfer between point-to-point, control and verify physical bills or central system; Intermediaries will be eliminated and human intervention reced. With the improvement of efficiency, financing channels are more unblocked, risks are lower, and multiple parties benefit
(4) securities issuance and Trading: realize quasi real-time asset transfer, accelerate the speed of transaction clearing
the application of blockchain technology can make the process of securities trading more concise, transparent and fast, rece the plication of IT system, and improve the efficiency of market operation. For stocks, blockchain can eliminate paper and pen or electronic form records, rece human errors in trading, and improve the transparency and traceability of trading platform. Citigroup and Nasdaq cooperate to promote blockchain applications
(5) customer credit investigation and anti fraud: rece the cost of legal compliance, prevent financial crimes
the customer information and transaction records recorded in the blockchain help banks identify abnormal transactions and effectively prevent fraud. The technical characteristics of blockchain can change the existing credit reference system, and store the data of customers with bad records in the blockchain when the bank concts "know your customer" (KYC)
equity crowdfunding:
There is no doubt that blockchain has development prospects, and the necessary condition for development prospects is to enter the mainstream market
North America blockchain infrastructure the oan (former aion network) founder and CEO Matt spoke published an article entitled "in order to successfully enter the mainstream market, blockchain projects must" eat dog food "in Forbes on July 24, in which Matt mentioned his views on how blockchain should enter the mainstream market - & quot; Eat dog food strong>
in the science and technology circle, there is a jargon called & quot; Eat dog food Dogfood (also known as eating your own dog food) refers to companies using their own procts and becoming users of their own procts. Many high growth companies (such as Microsoft, Facebook, Amazon, apple, Netflix and Google) also test their procts by "eating dog food" or help build credibility“ "Eat dog food" is often used to find and fix bugs, but it has another value: to create reliable use cases for the company's procts
this is worth learning from blockchain projects, because blockchain projects often hold & quot; Once built, they (users) will come naturally , which habitually leaves the responsibility of creating new and interesting blockchain applications to a third party
this attitude is very common, even the well-known blockchain summit consensus 2019 also held a conference entitled & quot; Once built, they (users) will naturally come: to build a global blockchain Center & quot; To discuss how governments around the world can make efforts to attract blockchain projects while balancing regulatory, investment and innovation needs
to be fair, this strategy may be effective for blockchains that only focus on people in the currency circle. For the security token, especially for the exchange represented by the transaction, it makes more sense - "supply creates demand" is the usual idea here, especially considering that the realization of these transactions requires the construction of complex infrastructure
in contrast, "eat dog food" is more likely to be adopted by blockchain project developers who seek mainstream audiences (such as those in financial instry, manufacturing and supply chain, identity management, etc.). If blockchain technology wants to enter these mainstream fields, blockchain companies must first "eat dog food". This can not only clearly prove that blockchain technology is feasible outside the coin circle, but also highlight that blockchain can not only optimize existing use cases, but also create new use cases
and the oan team has been adhering to this concept, and relying on the oan and aion's technology stack built over the years, it has developed a financial technology platform moves for independent workers
Matt said that in the development and development of moves, the team hopes that the relevant functions of the OAN blockchain network can be brought into full play, so it will focus on the following three aspects:
1. How to use the OAN blockchain network to improve the credit efficiency of the proct
there are two main considerations to improve credit efficiency: 1) can we use the mechanism of the defi market to rece the cost of capital; 2) Can the blockchain technology be used to increase the external trust in the credit process of moves. Here, moves will form a mechanism of "pooling wisdom", so that everyone can contribute to recing credit risk and increasing the credibility of credit process, and may even develop a micro guarantee mechanism in the future. Therefore, users will be able to participate in the market established by the platform as borrowers, lenders or guarantors
How to make the interests of procts and users consistentspecifically, by connecting moves with the oan network, and with the help of digital asset aion, a relationship of interest consistency is formed between procts and users, so that users can personally experience the success of moves procts and directly participate in the oan, a blockchain network supporting moves
3. How to create the first open system of financial reputation data with moves
this open system may become a substitute for traditional credit scores or related mechanisms. Over the years, banks and financial institutions have been using Equifax, Fico or other similar institutions' scores as risk indicators, and the moves team believes that the procts they are building will be a good start - the beginning of a more perfect and modern financial reputation system. This is a long-term goal
moves supports North American mainstream carpooling, take out and other casual work economic platforms, and will be the flagship open application developed by the oan on its blockchain network. In June, moves expanded its operations from Ontario to Alberta and British Columbia into western Canada
all the initiatives of the oan team adhere to the spirit of "eating dog food" and strive to make blockchain technology enter the mainstream market as soon as possible. Blockchain is not for the minority, but for the mainstream. In addition to the oan team, many projects and institutions in the blockchain instry are also aiming at this goal. Can you say that such an excellent and targeted blockchain has no development prospects
joint stock companies are divided into "listed companies" and "unlisted companies". The shares of a listed company are registered in China securities registration and Clearing Corporation, so its behavior of issuing shares or trading shares is regulated by the CSRC. Here, we don't want to explain more; The shares issued by non listed companies do not need to be registered by any institution, and can be confirmed by issuing shares and maintaining the register of shareholders. Of course, many of them are registered through third-party institutions such as the instrial and commercial department or China Securities Depository and Clearing Corporation, and use the local share custody center to provide third-party registration services for publicity. Moreover, when the company's equity changes, it is necessary to manually process paper equity certificates, option issuance and convertible notes. In this way, the company's stock rights can be changed, The maintenance of the register of shareholders will become very complicated, and the tracking and maintenance of transactions will become more difficult to trace with more and more transactions
if the techshares blockchain technology is used for equity crowdfunding, all the above problems can be perfectly solved. The blockchain account book is safe and transparent, and can not be tampered with. It is also easy to track, and can record the company's equity and its change history at any time
convenience of equity transfer and circulation
for equity crowdfunding, equity circulation is an important part of business, which can stimulate the activity of users and promote more registration and issuance. The traditional OTC over-the-counter equity trading is based on the credit of both sides of the transaction, and the two sides of the transaction bear the credit risk on their own. The transaction can only be carried out after the establishment of bilateral credit, and the trading platform bears the credit risk of market traders
techshares blockchain technology can rece the credit risk of transactions. In essence, it decentralizes the third party that provides credibility to a more thorough extent, that is, it is no longer limited to specific third party entities, but relies on all participants to jointly maintain a set of registration system. On the one hand, blockchain gives the right to record to the company itself, reflecting the spirit of autonomy; On the other hand, it can also ensure the openness, transparency and authenticity of information records, and minimize rights disputes. The ownership of equity is registered in the blockchain, and the equity transaction must be signed by the owner's private key to be verified; After the transaction is confirmed, the change of equity will also be recorded in the blockchain, so as to protect the interests of both parties
how to ensure safety
as an investor, the most worrying problem is the safety of funds. Traditional equity crowdfunding often has the problem of "double flowers" (Note: double flowers - Double expenses, that is, the only share is repeatedly transferred to two people). Until the electronic data is comprehensive, the central clearing agency ensures that the whole system can be leveled after trading. But the risk is often borne by the platform. Unlike traditional floor trading, equity crowdfunding business is carried out by many independent companies. Therefore, these trading activities are scattered on various platforms. With the techshares blockchain technology, the decentralized trust constructed by the blockchain can ensure the normal operation of the system and business without the need for mutual trust. Everyone becomes a node in the blockchain, with their own public key and private key, participating in rapid transaction verification and accounting. Moreover, in the initial stage of equity crowdfunding, the sponsors, crowdfunding platforms, investors and sponsors jointly sign a crowdfunding contract to agree on their respective responsibilities and obligations. The contract can be stored in the blockchain in the form of a smart contract, and the blockchain ensures that the contract cannot be tampered with ring the performance. In this way, there is no need to worry about safe space
it has strong expansibility, reasonable and legal
blockchain equity crowdfunding is composed of three-tier structure, and the bottom layer is blockchain network, which constructs a decentralized trust distributed system; The middle layer is the combination of business logic and blockchain to jointly establish account center, equity registration, equity voucher, equity transaction, equity management and other functions; The top layer is the crowdfunding platform for customer-oriented business, and the business of the platform can be extended to various fields and instries in theory
with techshares' blockchain technology, decentralized trust can be realized by building P2P self-organizing network, orderly and tamperable cryptography account book and distributed consensus mechanism. In addition, no matter the company law, the regulations on the administration of company registration or other laws and regulations, there are no specific restrictions on the form of expression of the register of shareholders maintained by the company itself. The company can choose to create and maintain the register of shareholders in any form with written records, not limited to specific carriers. Therefore, it is entirely reasonable and legal to use techshares as a carrier for equity crowdfunding on the blockchain. Once it is voluntarily chosen by the company, it can provide legal and effective proof for the company's equity (shares).
the blockchain project crowdfunding platform is essentially the same as the traditional equity crowdfunding platform
it can be said that blockchain project crowdfunding is a subcategory of equity crowdfunding
equity crowdfunding is limited by laws and regulations, which limits the number of investors and the amount of investment. At the same time, investors need to be audited. The participation cost and threshold of ordinary people are relatively high, and the target group is high net worth people
the liquidity of equity crowdfunding is poor, and it often takes a long time to exit, and even most of the projects invested in are like drifting away
blockchain crowdfunding is a bit similar to national crowdfunding, because its crowdfunding funds are settled in bitcoin and there are no laws and regulations. Therefore, there are not too many requirements for the number of people and the amount of investment. The investment cost is low, but the threshold is relatively high
because blockchain projects are based on the underlying technology of bitcoin, it is difficult for ordinary people to understand them. In fact, they can be simply regarded as a technical way of distributed collaborative work
the success of blockchain projects in the market is relatively few, so there is no unified reference standard, and the project depends entirely on personal judgment. Settlement is concted in bitcoin, so if you need to participate, your requirement is to accept the high risk threshold of digital currency There are many projects that cheat money)
blockchain crowdfunding has good liquidity. After the emergence of the so-called "token", it can be completely traded out, and the fluctuation risk is also very high
of course, as a technology being studied by the central bank, the blockchain project is worthy of attention, but it also needs to be cautious. As for the ico365 platform, it is recommended that indivials examine their own judgment. There is no evaluation basis for the new platform.
1. Platform crowdfunding projects are supported by physical assets
2. Users with tokens will receive regular share dividends
3. European crowdfunding has a special allocation fund, and the compensation amount is as high as 80%
4. Good launch mechanism. Digital currency can be freely traded in the market.
hope you are satisfied, thank you!
our final solution is to introce the regulator node, open data query to the public, make the fund flow transparent in the crowdfunding process, give effective feedback to donors, and the regulator can also effectively solve the key lag problems,
realize real-time supervision, so that the crowdfunding platform can develop orderly and healthily.
