Bitcoin wallets at present are stored with no encryption whatsoever by default,.Looks like we both independently arrived at similar methods of explanation.This is almost the same as being paid, as you will learn in later steps.No matter what the outcome, this process ensures that the block chain has an agreed-upon time ordering of the blocks.The bitcoin website can help you locate merchants willing to work with you.For the proof-of-work idea to have any chance of succeeding, network users need an incentive to help validate transactions.What is, I believe, much more interesting and enjoyable is to think of Bitcoin and other cryptocurrencies as a way of enabling new forms of collective behaviour.
However, over time only one of the forks will become the accepted consensus for confirmed transactions.But while you can understand the mechanics of Bitcoin through such a one-shot explanation, it would be difficult to understand why Bitcoin is designed the way it is.My broad point about asymmetries is still true, however. (And is vividly demonstrated by the rise of large mining pools.).Does everyone have their own version of it or do they sync to a master.
