bitcoin blockchain technology explained
As the number moves toward the ceiling of 21 million, many expect the profits miners once made from the creation of new blocks to become so low that they will become
negligible. Super powerful computers called Application Specific Integrated Circuit, or asic, were developed specifically to mine Bitcoins. In their enthusiasm, they can speed past the fundamental question of what blockchain was really designed. The integrity and the chronological order of the block chain are enforced with cryptography.

This is what allows bitcoin to transfer value across the globe without resorting to traditional intermediaries such as banks.
I say almost impossible because it would take some significant computational power to even attempt something like that. If we were to reclaim our virtual data, and take control over how much and who we give it out to, wouldnt that be a great step towards helping us protect our privacy? Perhaps the biggest use of blockchain technology is in identity management, as described in this insightful. Blockchain solves the Double Spend problem without a digital reserve fund or similar form of umpire.

This is a question that often causes confusion. Thus, the integrity of the blockchain requires a great many participants. Miners solve complex mathematical problems, and the reward is more Bitcoins generated and awarded to them. But let's take a step back. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. Think of it as a kind of highly encrypted and verified shared Google Document, in which each entry in the sheet depends on a logical relationship to all its predecessors. These are then collected and created into a digital profile of us which is not owned by us!
