Trust is an important concept. If you have fiat in your bank account you trust the bank to let you borrow your own money when you want to use it outside the banking system. When you do that they change an IOU number on your account balance. They just owe you less of your money.

As far as I know, you can only trust people to "borrow from you", while you can't chose who will trust _you_ to borrow from _them_. I too am concerned about owing money to random people just because they trusted you.

@Lohoris well, I transferred some BTCs from Bitstamp to my ripple.com account. I had to create a trust to a ripple address @Bitstamp to receive those BTCs. Ignore for a second that it was me transferring BTCs to myself. My interpretation of this is that I had to create trust to someone in order for that someone to `let me borrow` his BTCs from him. Incidentally, when people just send me XRPs or BTCs to my ripple address at ripple.com, or when I do the same to them, no trust setup is involved. **I am definitely confused.**

Ripple two types of trust. Or no?

# Ripple two types of trust. Or no?

(Asked by: username_0 on 2013-04-21)

I tend to distinguish two types of trust:

a) I trust you to **lend me** XXX in quantity up to N units.

b) I trust you to **borrow from me** YYY in quantity up to M units.

However, ripple documentation appears to not make such a distinction. At least not clearly and explicitly.

Using ripple.com client I can trust someone to lend me, but I see no way to trust someone to borrow from me.

Can you help clear this conceptual hurdle for me?

I've been lending & borrowing all my life and never, ever was I confused about who owes me and whom do I owe. Now, with the advanced mathematical currency & exchange system I am not sure about that anymore.

The only risk would be that somebody owes you money and doesn't pay you back. If someone lets you owe them money, they are taking all the risk. You have to choose to take a risk, but normally you'd have no reason to want to control whether other people take risks.

> a) I trust you to lend me XXX in quantity up to N units.

This is the type of trust you extend when you create a pathway.

> b) I trust you to borrow from me YYY in quantity up to M units.

If you mean you trust them to pay you back, *they* would have to agree to pay you back and you would have to accept and act on that agreement. That would take place outside the Ripple system. The Ripple system just tracks balances, the terms on which those balances are paid back is outside the system.

I'm not sure why you would worry about someone giving you money without you having any agreement to pay them back. All the risk is on them.
