1) who wants to hijack the existing blockchain? just post your ip!
Lolwut?
The github src is out there already and predictable IPs. has a test genesisblock right now (tho kinda disabled, just remove the one part of that line as per a post back in thread), and voila, we have a testnet going!

Or, a REALnet, if we decide to trade on its value! Only a lot of convincing yelling in the forums could make our chain be abandoned! Thats how all these coins work!

Politics is inherent in the system (ie if we had no block explorer, pools, etc, then our chain might die)...
how about: ignore any coins that have the same miner address twice in a row for the first 10k or 20k blocks (or make it time based? first 72 hrs? 96?)
What is "miner address"?
Wallet address? I can make any count of them.
IP address? I can make... well, a couple subnets of them.
you know what i meant. i was being lazy.
can you mine at a new address on the same card every block? I think that would be prohibitive.
i know you could make a new wallet for every card mining in a big rig farm, of course :/ just trying to think of a way for orphans to be reduced somehow, by not allowing multiple blocks from rigs to be instamined with 0.00 network latency, orphaning everyone else's - i believe double the power is more than double the reward during orphan times. I'd like to flatten that.
Any suggestions?
(making the block rate actually be 2 minutes and not 2.5 seconds at the start like all new coins would be good. but the retarg delay wont allow that.)
