Description

A Cryptographic Liquidity Borrowing Method Using Block Chain}

The present invention relates to a liquidity loan method, and more particularly, to a method of loaning cryptocurrency liquidity using a blockchain.

Loan financing of financial institutions such as banks and credit companies is an important part of modern society, and various technologies have been developed for the existing financial services related to such loans. However, in the case of such a conventional loan financial services, since the financial institutions manage the loans to the borrowers once they are managed by the financial institutions, the risk that the loans cannot be recovered is the structure that financial institutions have to bear most of them. .

To this end, peer to peer (P2P) loans are being proposed as a new loan method where a large number of investors (creditors), rather than banks or private banks, collect money and lend it directly to individuals or companies. P2P loans are all online and can reduce recruitment and labor costs.Investors can earn higher profits than bank interest rates. The market is growing rapidly due to various advantages, such as possible.

The P2P lending market is showing rapid growth in the background of the global financial crisis and internet-based technological innovation. In line with this, startups using various business models have attracted the attention of lenders and investors.

However, such a P2P lending system also, rather than direct transactions between individuals, basically a centralized specific financial service providing device performs the process such as the demand for the loan and the opening of the product, according to the individual loan and collateral setting, As a result of the return process, the centralized service has resulted in the centralized growth of the scale, which is now difficult to access unless it is a large business such as a lender.

As a result, in centralized lending financing, lenders are centrally focused on both risk and excess profits, and because large businesses require capital raising, the average individual, small and medium-sized groups are gradually excluded from centralized services. It is difficult to take advantage of profits, and it is necessary to introduce a platform to solve them.

Meanwhile, cryptocurrency, which has recently emerged based on blockchain technology, is also called virtual currency and is growing as a means of payment of goods and services. However, these cryptocurrencies do not have a sufficient legal basis for their use at present, so they are free to be issued and distributed, and thus have high liquidity.
