Description

A Cryptographic Liquidity Borrowing Method Using Block Chain}

The present invention relates to a liquidity loan method, and more particularly to a cryptocurrency liquidity rental method 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 current financial services related to such loans. However, in the case of such a conventional loan financial service, since the financial institution manages the loans to the borrower once the financial institution manages them, the risk that the loans cannot be recovered is the structure that financial institutions must bear most of the financing, and the limitation was limited. .

To this end, peer to peer (P2P) loans are being proposed as a new lending 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.

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

However, the P2P lending system is also not a direct transaction between individuals, but rather a centralized financial services provider performs processes such as demand for loans and product opening, and accordingly 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 they are businesses that require large capital raising, individuals, small and medium-sized groups are increasingly excluded from centralized services. It will be difficult to take advantage of them, and it is necessary to introduce a platform to solve them.

Meanwhile, cryptocurrency, which recently emerged based on blockchain technology, is also called cryptocurrency 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, which makes them highly liquid.
