Hello, I might as well get the ball rolling. I am having difficulty understanding the trust-free exchange offer example in the white paper.
First, there's mention of trading 10 shamir for 1 primegold. I had first assumed that this was another contract-based currency. However, the shamir-contract is never contacted. Instead, the tx.sender(Is this the PrimeGold contract?) is sent this: valuesent * 10485760. I don't know what that is. Valuesent should be 1. If the exchange was for 10 shamir, then the exchanger-contract should have sent a transaction to the shamir-contract. What is it sending to the PrimeGold contract? Ether?
