Speeding up bitcoin transactions?
The security of the Bitcoin system depends on time passed since the transaction was included in a block.  Let's call this confirmation 1.


  Are you having trouble getting your trades into a block, or want to have more confirmations?


The fact remains is that you should wait 1 hour after the transaction is included in a block before spending that output.  That one hour just happens to roughly correspond with 6 blocks.

So why do we wait 1 hour? It's because we want to make reasonably sure that no one out there has a computer strong enough to spend the output twice, and causing a split in the ledger.

I wouldn't plan on basing my business on short block times, and would instead only use the block chain for deposits and withdrawals from your private system. 

If you're having trouble getting your Tx included in a block the easy solution for that is to pay transaction fees, or run a private mining rig that will accept such transactions.
