There have been suggestions of proof of work requirements that exclude GPUs or ASICS (or try to) but I was wondering if anyone had suggested a proof of work that is not suited to being solved by computer at all, so that the miners would be humans working on proving their own work done – work that cannot (currently) be performed by a computer in a competitive amount of time.
This would presumably need to be quickly verifiable by computer, but not independently solvable by computer.
If this hasn’t yet been proposed, is there any apparent reason this would not work?
This question is similar to previosuly asked question Start a Private Bitcoin Network but since I can’t comment there I am asking again.
I am working on a concept specifically for existing bitcoin so the suggested methods of
regtest are not applicable for my purpose. I need to simulate a bitcoin network over my LAN/Wifi and it would be great if someone could point me towards a method to do it.
How can I search for a transaction to or from a certain address in the block chain within a particular time period?
I am trying to answer if this transaction occurred on 17 Oct 2014. Hence, instead of searching the entire block chain, it might be faster to search block chain, starting 16 Oct 2014 and ending on 18 Oct 2014.
