Description

Blockchain-based research-oriented crowdfunding platform operation method {Crowd funding platform for research goods based on block chain}

The present invention relates to a method of operating a blockchain-based research-oriented crowdfunding platform.

CROWD FUNDING Funding is an investment method that raises funds from the crowd through the Internet. In the United States, "generally, using a community to collect small-scale sponsorship or investment funds from individuals" is defined. It is also called "Social Funding" because it is often advertised through social network services (SNS). Such crowding funding can be divided into three types: angel investment type, self-support support type, and public interest support type. Angel investment type means investing in an early stage company that has no products but has only ideas for ordinary investors. It provides opportunities to start a business even for small-cap entrepreneurs, who were difficult to access, and the self-support type is a case of supporting the self-sufficiency of individuals who have difficulty in living through internet micro-loans, by directly connecting people with money and people without money. Provides a channel through which surplus funds can be easily transferred. In addition, the public interest sponsorship type refers to a type in which the sponsors sympathize with the purpose of the fundraiser and support the project promoted by the fundraiser without wishing for a financial benefit.

Currently, it is carried out using social network services (SNS), but crowdfunding in which artists or social activists with insufficient funds disclose their creations or social public interest projects on the Internet and receive a small amount of funding from the crowd. This is an example. In recent years, founders and even politicians with ideas have applied this not only in terms of financing, but also in terms of marketing, and it can be said that candidates collect deposits through funds in general elections and local elections. Since in 1997 in the UK, the rock group Marillion raised $60,000 for US tours through the Internet, a crowdfunding site, Indigogo, was opened in January 2008, and some sites are also operating in Korea.

In addition, the US is actively legalizing this financing method by passing a bill called the Jobs Act (JOBS ACTS).

However, no matter how advanced SNS is, there may be differences in the degree to which it is known to the public, so some funding is marginalized, and it is not easy to collect as much money as necessary in a short time.

Republic of Korea Patent Application No. 2001-0004693'The fundraising service and fundraising voting service system and method using an electronic bulletin board' enables account transfer through a virtual account, and links the electronic bulletin board created for each target targeting a large number of donors. Although it is possible to set the fundraising period and the fundraising amount separately, it is possible to set the fundraising activity separately, but since it requires a separate action such as accessing the electronic bulletin board and posting a post, there are many bulletin boards that are marginalized unless there is a separate action to focus the attention of the fundraiser. It has to be created. In addition, there were many cases where the fundraising amount was less than the original target fundraising amount.

In recent years, it is making investment payments with enhanced security through a blockchain method, but it has not been proposed as a technology product funding platform.

Blockchain is known as an independent method and an open source method,

To enable the use of digital currency, the Libra blockchain provided by the Libra Association is known as an open platform used by Facebook and others. This is to prevent counterfeiting as the version is additionally recorded as transaction data each time a version is used, and the first used version is checked even if forgery is attempted later, and the first use data is distributed and stored in several places to check multiple times. The way it can be is known.

The present invention is to solve this problem, and the object of the present invention is to perform crowdfunding on a crowdfunding platform provided by a funding server, but fund a technology or research project developed or planned for development by a corporation or individual, and cryptocurrency in the crowdfunding platform It is intended to provide a method of operating a blockchain-based research-oriented crowdfunding platform that enables safe investment by allowing the transaction confirmation server and the cryptocurrency transaction processing server to be linked so that funding funds can be exchanged for blockchain-based cryptocurrency.

For this purpose, the present invention sells an evaluation server for evaluating technology or research projects by receiving a funding request from a funding server upon request of an investor terminal, a research and development terminal, and a research and development terminal, and the evaluation technology or research project of the evaluation server for each project.

1. Terminology

end. The first generation of blockchain technology that introduces a peer-to-peer system of distributed ledgers that deviates from the management of a central server through a new cryptocurrency called Bitcoin-blockchain.

I. A method of providing a distributed computing platform for implementing smart contract functions with the second generation of Ethereum-blockchain technology. Ether, like bitcoin, is traded as a kind of cryptocurrency in cyberspace, and is the most representative altcoin and blockchain platform.

All. Blockchain platform distributes and stores data in each block (server) of members (nodes) participating in the system, making it virtually impossible to falsify or alter data (reliability), and members can each retain distributed information. (Transparency), there is no need for a separate central server administrator.

It contains the cryptographic keys of user information for storing, sending and receiving, and transacting cryptocurrencies linked to this blockchain technology, and the implementation of this is the electronic wallet of the blockchain.

la. Electronic wallets in the blockchain are wallets installed on mobiles and PCs, software wallets made of wallets using Internet browsers, hardware wallets that actually exist like USB and store cryptocurrencies securely, and print on paper with confidence. There are paper wallets that you can carry, and exchange wallets made to make transactions easier on the exchange.

hemp. Wallets installed on mobile and PC use Full Node Client Wallet installed wallets that can directly support the coin's blockchain by determining the authenticity of the transaction through the Full node and blockchain stored online. There is a thin client installable wallet that synchronizes relatively quickly because it is used.

There are two types of electronic wallets: Hot Wallet, which is connected to online for transactions, and Cold Wallet, which is disconnected from online.

bar. Encryption technology includes symmetric and asymmetric encryption technologies.The symmetric encryption setting method is to unlock the password when the familiar ID and password match, and the asymmetric encryption technology is the public-key and private key. It is divided into (Private-Key) and is divided into a Private-Key, which has full access rights to the encrypted content, and a Public-Key, which can verify authenticity by symmetrical to the private key. The chain-based electronic wallet is made of asymmetric encryption technology (conventional virtual currency system technology-see Patent Registration No. 10-1628007).

four. When an electronic wallet is installed, a public key (which corresponds to an ID) and a private key that acts as a secret key (password correspondence) are created, but the combination used here is too long to be copied. There is a drawback of using it or storing it separately. To this end, there is a blockchain-based cryptocurrency and electronic management system that includes a function to reset a familiar symmetrical password or additionally set a body identification code and OTP (One Time Password) function on top of asymmetric hashing technology. (See Registration 10-1904208). This is summarized in Table 1.

2. Additional terminology (refer to Korean Patent Publication No. 10-2019-0120680)

end. Transaction

When you make a transaction with someone using Bitcoin, the sender's device creates transaction history data called Transactions. This data contains information about who sends to whom and how much bitcoin.

I. block

Mining refers to the process of collecting transactions generated in the Bitcoin network to create one block and to make the block included in the blockchain. Blocks occur about every 10 minutes, and are designed to be no larger than 1MB, and include about 1000 transactions on average.

All. Blockchain

The nth block is a form that proves that the n-1th block has not been forged, and its appearance means that the block is woven into a chain.

la. Bitcoin address

If the bank account number is required when making a transaction through a passbook, the bitcoin address is required when making a transaction in Bitcoin. In the case of a bitcoin address, it can be represented as 19iZnngPRx*******AyiFGp97SavWCPg7y, and usually the first character is 1, and the next is a mixture of random numbers and characters.

hemp. Mining

When a transaction is approved in Bitcoin, it is not when a transaction is created, but when the transaction is included in the blockchain. The mining process refers to the process of including the block containing the transaction into the blockchain. If the block is successfully completed and included in the blockchain, the miner can obtain a certain amount of bitcoin as a reward.

bar. wallet

Bitcoin recommends discarding once used Bitcoin addresses for security. However, then, I need to record both the bitcoin address that I have used so far to find out the bitcoins that I have and the secret key that will prove that I am the owner of the bitcoin address. Software called a wallet is used to manage this information.

four. Bitcoin Core

There are many ways you can use Bitcoin. You can use a bitcoin wallet implemented as a smartphone app or a bitcoin wallet implemented on the web, but the origin of all these wallet software and now as a reference is Bitcoin Core.

Ah. Digital currency

Digital currency is stored in a computer or used on a network. It refers to a currency that can be used portable by digitizing the monetary value on an IC card and storing it in an encrypted form. Therefore, digital currency includes all of electronic currency, virtual currency, and cryptocurrency. Digital money is sometimes used interchangeably with electronic money, but electronic money is issued in exchange for the same value as cash or deposits according to Korea's Electronic Financial Transactions Act. In addition, it has a more limited concept than digital currency in that it guarantees that a financial company or electronic financial business that is an issuer can exchange it for cash or deposit.

On the other hand, virtual currency, unlike electronic money, is not a financial company or electronic financial business entity but a company. Cryptocurrency has a value equivalent to the money paid to purchase cryptocurrency, and there is a limit that can only be used within the service of the issuer. Examples of virtual currency include social currency, internet coupons, mobile coupons, and game money that are used as economic rewards for activities in social networking services (SNS). Cryptocurrency is a currency that does not have a central authority to manage it, and unlike other currencies, its value is not fixed and fluctuates according to supply and demand. Representatively, there are Bitcoin, Ethereum, and Ripple.
