I've been working with Nicolas to help get this done, but I think hes pretty busy.
I've got code to Issue colour coins from Bob to Alice. However, I cant get a transfer of the assets.
Bob -> 20 Gold -> Alice
Alice -> 10 Gold -> Doof
This is where Im getting stuck. After the tx builder I get a valid tx hash. However if I broad cast nothing happens. Some code snippets, sorry for the commenting, been trying lots of different approaches.
Ill pay once working code is submitted. Im using blockr or coinprism as a repo to get the txs. Happy to hard code a tx hash and script sig to pay the bounty, as long as I can retrieve new ones in the future from my repo.
Notes:
INetwork just calls my bitcoin-core client
