so. the blockchain is needed to sign the transactions, and include the proof (pics, (evtl vid) geodata, time, sourrounding nodes) in the deal.
The blockchain is NOT used to sign transactions.
plus me wantz to have teh control!
Then you neither want nor need a blockchain.
The purpose of the blockchain is to have "control" when nobody is in control. Rather than trusting a single person (like you) the network trusts the chain w/ the most computing power figuring most of the computing power is legit. If you are in control you know exactly who is legit and who isn't and thus there is no need for a blockchain.
concerning the budget, i would be happy, to pay someone a 150 bucks n hour, as our leading early bird heads get a million a year...
Awesome.
