Over the past few years, global financial companies have attracted attention by declaring the development of business models using Bitcoin. However, contrary to the announced plan, the traditional financial sector has not been able to properly provide financial products to the general public, centered on Bitcoin, to date. Services such as Bitcoin purchases, savings, investments, and mortgage loans still feel like pie in the sky.
Some adventurous investment companies that have recognized the potential of Bitcoin have launched Bitcoin-related funds and listed them on Nasdaq, but these are products that only a limited number of investors can access. So why is Bitcoin-secured lending, which is considered a representative use case of Bitcoin, not taking hold in the traditional financial sector? This is not simply due to Bitcoin’s price volatility or future uncertainty. A more fundamental problem arises from the gap between Bitcoin’s technical characteristics and traditional financial systems.
The essence of Bitcoin: ownership and transfer
Understanding the characteristics of Bitcoin can help you understand why traditional financial approaches have failed. Bitcoin is a digital asset that has no physical entity. Ownership of Bitcoin is determined by the owner’s public key address recorded on the blockchain, and sending Bitcoin is simply the process of changing this ownership record. This is conceptually similar to changes in ownership recorded in the real estate register.
However, the important difference is that actually “owning” a Bitcoin is the same as knowing its private key. If the private key is leaked, the owner loses control of his or her Bitcoin, which means loss of assets.
Problems with exchanges and collateral loans
Another issue related to Bitcoin ownership involves exchanges. Many people purchase and store Bitcoin through exchanges, but the Bitcoin stored on exchanges is not actually owned by the user. This is the main reason why individuals lose their Bitcoin when exchanges go bankrupt or are hacked.
Bank failures usually occur due to failure to recover loans or investment losses, but most exchange failures occur due to leakage of private keys due to hacking. This shows that the security model of the traditional financial system does not effectively address the technical characteristics of Bitcoin. While traditional finance is designed around a centralized security model, Bitcoin operates around decentralized ownership and public key infrastructure (PKI).
Bitcoin collateral loan solution
To successfully implement Bitcoin-backed loans, the traditional deposit-backed loan model cannot be applied as is. A new approach is needed to ensure the security and ownership of Bitcoin.
1. Borrowing real estate collateral model
In order to issue a loan using Bitcoin as collateral, a technical infrastructure that can treat it like real estate is needed. In a real estate loan, ownership is recorded in the register and a lien is placed on the asset for the duration of the loan. In Bitcoin, smart contract technology can be used in a similar way to store Bitcoin in a locked state for the duration of the loan or establish a lien. Through this, the collateralized Bitcoin can be safely managed without risks such as leakage of secret keys.
2. Utilization of Multi-Signature technology
There is a way to use a multisig wallet to reduce the risk of hacking related to storing Bitcoin. Multisig can be configured to require multiple private keys to execute a single transaction. When executing a loan, the borrower and the lender each hold a key, and an exchange or a trusted third party may hold additional security keys. This prevents a single entity from arbitrarily moving Bitcoin.
3. Convergence with DeFi
The Bitcoin collateral loan platform utilizing decentralized finance (DeFi) is an area that is difficult for traditional finance to access, but can provide a technological solution. For example, a smart contract can be used to lock Bitcoin as collateral and design loan execution and repayment in an automated manner. This greatly reduces the risk of exchange bankruptcy or secret key leakage, and ensures safety while maintaining decentralized characteristics.
Conclusion: Direction of financial innovation
Bitcoin-secured loans cannot be successful by simply applying existing financial models to Bitcoin. This requires a new approach that takes into account Bitcoin’s unique characteristics and technical requirements.
Innovative technologies such as multisig, smart contracts, and DeFi will be the key to making this possible. The traditional financial sector must actively accept these technologies and move toward understanding the characteristics of Bitcoin. The day Bitcoin-secured loans are successfully established, it will become a new jumping-off point for the financial industry.
Beyond financial applications, what other use cases could emerge for Bitcoin as collateral in the future? Could it extend to areas like identity verification, supply chain finance, or even voting systems?
