Financing is the advancement of funds in exchange for a promise that those funds will be repaid later. For this to work the borrower must own assets that can be seized in the event of default. Since blockchain-based assets cannot be seized, this means financing is fundamentally impossible using blockchain technology. The best they can do is overcollateralised loans, where the borrower must first advance themself the…
> blockchain-based assets cannot be seized I don't see the distinction you're drawing. If they've been deposited into a smart contract like a Maker CDP, then they can be liquidated, which is much like being seized and auctioned in traditional finance. > Funds are simply swapped. If I take a margin loan against some TSLA stock, would you say I've swapped TSLA for cash? Most people (tax authorities included) would say…
Imagine you want to make purchase, but you don't have the funds. You have two options. Option A, you save money first, until you have enough funds. Option B, you borrow money, and save later (while you repay the loan). In economics, option A is called "saving" while option B is called "financing".
Collateral isn't strictly necessary, but it's useful because it reduces credit risk and therefore lowers the cost of borrowing funds (i.e. the interest rate that the borrower is charged). However, notice that if the collateral is equal or exceeds in value the amount borrowed and it is deposited with the lender until the loan is paid off, this is no longer option B, this is option A. This is not financing.
Financing requires that the collateral (if any) is not deposited with the lender until the loan is paid off, or that, if it is, it doesn't cover the whole of the borrowed amount. For financing to work, you need legal procedures that enable the lender to seize the borrower's assets in the event of default. You can't do that with smart contracts, because smart contracts can't seize assets that are in somebody else's wallet. You can do other things for sure, but not financing.
