Modify Bitcoin Client

Closed

I need someone to modify the open-source project at [url removed, login to view] I am currently developing a gaming front-end for a client that resembles [url removed, login to view] .

Please make sure you familiar with how they verify Bitcoin transfer with 0 confirmations here,

[url removed, login to view]

The client needs to be modified to do this

"A transaction claims some outputs from previous transactions and then creates new outputs whose summed value is equal (or less in the case of fees) than the sum of the claimed outputs values."

My PHP script will be connecting to the bitcoin client via RPC. I will want to pass it the initial TXID and tell it how much to send back to the user that sent it. The client will be connecting to my database by PHP Scripts performing GET OR POST queries to report back on new transactions received and all pertaining details as well as successful transactions executed. Please research how to accomplish this and write a detailed proposal.

Skills: C Programming, C++ Programming

Huh, with that rising difficulty I expect GPU miners to stray into the pack and form a special pool for Finney attack :) If you really want to take 0-confirmation route take a look at my proposal in PM.
