dexX7 / Almost trustless direct sale
Created March 9, 2014 23:08
Say, you want to buy some Mastercoins, but you are not sure, if the seller wants to scam you.
Step 1: The Seller prepares a signed "send" transaction and tells the buyer the transaction hash.
Step 2: The Buyer prepares a signed transaction for the payment and uses the "send" transaction's hash as input.
The buyer then sends the seller the raw transaction and the seller broadcasts both.
If the seller invalidates the "send" transaction, his payment is also invalidated.

Embedded proof of verification
Current situation:
- Mastercoin is balance based
- Advanced system states exist (ongoing crowdsales, accepted orders, ...)
- Clients reconstruct the view of system by verifying all transactions
starting at Exodus according to a client side set of rules
- Mastercoin transactions are a subset of all Bitcoin transactions
