This helps explain why, while the team is composed largely of mathematicians and computer scientists, many of them work on research problems in genomics, biology, and medicine. Why don't miners write themselves a transaction for a thousand bitcoin instead of the correct reward? Those miners who act dishonestly have their blocks rejected and not only lose the reward, but also waste the effort expended to find a Proof-of-Work solution, thus incurring the cost of electricity without compensation. The counter parameter is small at bits so each time it wraps the extraNonce field must be incremented or otherwise changed to avoid repeating work. |
