As part of a Bitcoin service I am developing, I am going to be performing Bitcoin transactions from users in bulk, rather than immediately as part of the security design (hard to attack a system if a reply to your request comes 30 minutes later).
A thought came to mind today. Instead of running *insert amount* transactions at once, would it actually be cheaper in fees to put all the inputs and outputs from all them transactions into one massive one? Would this cause problems for the network, and mining in general if was possible for my node to throw a single TX out that was nearly 500KB in size for example?
I'd rather not cause problems for nodes, or have miners unable to add my fat ass transaction as it pushes the block size too high.
