Binary Options Trading Temporary discrepancies between chains are resolved eventually as more proof of work is added, extending one of the possible chains. Mining nodes “vote” with their mining power by choosing which chain to extend by mining the next block. When they mine a new block and extend the chain, the new block itself represents Dec 11, 2017 In this post we explain "why" and "how" of bitcoin energy. We also explain mining efficiency and the new proof mechanism called "proof of work". This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash clustered mining activities.
