Ok thanks guys. So I should use it when I'm loaning my coins to secure the transactions. I guess there are fees? Anyway thank you I'll look for this list.
In case of loans an escrow would usually hold the collateral for you. Since not only those that ask for loans could scam, but also those that appear to give loans.
Lets say you loan to Alice and use Bob as Escrow.
Alice would send the collateral to Bob.
Bob secures the collateral and informs you that they have received it.
You send the BTC to Alice.
scenario #1
After Alice paid her debt, you inform Bob and he returns the collateral to Alice.
scenario #2
Time passes but Alice does not paid her debt, Bob sends the collateral to you which is now yours to sell or keep, etc.
