Bitcoin can thus be understood as a technology that converts electricity to truthful records through the expenditure of processing power.
Those who expend this electricity are rewarded with the bitcoin currency, and so they have a strong incentive to maintain its integrity. As a result of attaching a strong economic incentive for honesty, Bitcoin’s ledger has been practically incorruptible for the period of its operation so far.
By relying entirely on verification, Bitcoin dooms fraudulent transactions to failure and obviates the need for trust in anyone for transactions to be completed.
