Thanks for your reply and apologize if I re-asked a question. My point is, can we run our own BC. We give the hardware a hash and a difficulty and ask it to return the nonce that solved the POW. Is this possible? Thanks

Dear All, I am currently working on a research project and I am wondering if it is possible to buy mining hardware and use solely to solve some hash puzzles? In another word, I want to solve my own POW by Bitcoin mining hardware. Is this possible? I mostly am in favor of ASIC hardware, since I need a small and cheap miner for my research. Regards

Thanks, You answered all my questions clearly, many thanks for your clear illustration.

now i get it, so how miners figure out this problem? I mean how they can make sure that they are not mining a transaction which is mined before?

But miners listen to network and capture received transactions to their block, what if two miners capture the same block (which is possible) and then mine it in different blocks? its not double spending since its one unique transaction, input and output are the same not different.

Hi As you know, different miners may try to mine blocks in blockchain, and it is possible that one transaction being added to different blocks. How blockchain face with this problem? In other world, is it possible that one transaction be in two or more blocks? if not, how other miners find out that their transactions are stored in blockchain?

Now, the most important question is that how can we simulate and modify block chain for other networks? can we use Simbit or other related simulators to do that? or we have to write a different simulator? for instance, how can we simulate block chain for cloud storage or cloud service? I am looking forward to hear your ideas. Here you can find a simulation program created for research purpose, it's based only on PoS but maybe you can improve it and add other consensus algorithms: http://consensusresearch.org/#scorex https://nxtforum.org/consensus-research/scorex-ultracompact-cryptocurrency-engine-for-researchers/ thanks, it seems that scorex is relevant to my research but the problem is that I installed it and now i do not know how to start or how to customise it. I cant find how to make a blockchain ( even how to work with its default version). Do anyone has idea?

thanks By my point is how to simulate it? designing a particular block chain may be possible but how to test it? just imagine you want to store some files in cloud and use block chain to do that, now, how can we implement such a network?
