I have been scammed by a person and I want to dispute a bitcoin transaction.

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?

I understand that to mine bitcoins you need the hash of the previous block, and in order to resolve possible forks. But why not just have the last 100 blocks (or more whatever is appropriate) and keep a sliding window of the last blocks?

I bought bitcoins a while ago, an investment, but have now been reading up on cloud mining.

Due to the cost of bitcoins rising, is now a good time to invest in cloud mining?

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 litecoin or 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.

I’m new in bitcoin, I just want to return json scrutucture from latest transactions from time to time.

I couldn’t figure by searching their reference, I think it requires a level of knowledge in bitcoin I don’t have yet.

I just wanted to return plain vanilla json array

thanks

The following bitcoin addresses are involved in FRAUD…

Where can I report bitcoin scammers?

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.

What’s the core difference between the mining and wallet software out there? I haven’t been able to find any information on this so anything – technical or non is appreciated. Though I’m talking about the wallets that make you download the block chain as well, not the light wallets. Thank you.
