Question

Issue asset in the transaction

I want to issue assets in some transaction,
for example:
Buyer A, Seller B
B sell an asset (call "beef") to A, but B don't have "goods" in chain.(but B have "beef" in real world)
A want to buy this "goods" from B by an asset (call "pork"), but A also don't have any "pork" in chain. (but A have "pork" in real world)

So A and B exchange "pork" and "beef" in realworld, and they issue "pork" and "beef" in chain to exchange.

How can I do that?
I know that is risk for the blockchain, but this is my academic testing.

Answer 1

You would have to create an address with 'getnewaddress' for each party then use 'issue' or 'issuefrom' to create an asset and assign it a value. This is to put both parties into the blockchain and create the assets 'pork' and 'beef' with initial values.

To do the actual exchange you would use 'send' or 'sendfrom' to send the asset from the one party to the other party.

thanks! I got it!

You can perform the exchange in a single atomic operation, rather than two separate sends, using the exchange APIs. Tutorial here: https://www.multichain.com/developers/atomic-exchange-transactions/

Ok!
So, I must be issue assets for each party, then exchange that two assets, not send asset for each party.
