> If you want to do fractional reserve in say crypto you need to have a blockchain where the “bank” can print crypto like they do with current currency until then it’s off the books accountign or a ponzy scheme like MtGox. Okay, I think maybe what we're arguing about is definitions. I'm trying to say, "off the books accounting" is perfectly legitimate fractional reserve. It is not possible to create more on-chain Bit…
That’s not a fractional reserve since that one needs to be in the same unit of account if you are using two units of account that’s not a fractional reserve that is an exchange rate. If you loan less than your total then again it’s not fractional lending it’s simply lending.
> if you are using two units of account that’s not a fractional reserve
The system I described only has one unit of account, Bitcoin. It doesn't matter whether they're on-chain or "virtual", they're both Bitcoin, and are worth the exact same amount.
> If you loan less than your total then again it’s not fractional lending it’s simply lending.
You have misunderstood fractional reserve banking. Banks are not allowed to give out more money than they have received in deposits. Here's Wikipedia:
> Fractional-reserve banking is the practice whereby a bank accepts deposits, makes loans or investments, but is required to hold reserves equal to only a fraction of its deposit liabilities.
Say the reserve ratio is 10%. Then, given $100, the bank is allowed to give out $90 and must keep $10 on hand.
