Imajstorovic has been testing how much money he could make using a Vampire accelerator for mining Bitcoins. He could mine 0.00000577 Bitcoins per year or in today’s value exactly 0.08552 USD. In other words he would need 173 310 years to mine one Bitcoin. Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain. This way, no individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends.
