Blockchain getting startedEthereum source code analysis ethereum random number generation method 2. Incentive The RNG cycle is very short. For example, if there are 20 generation cycles in one hour, if the profit without a cycle is 0.001%, the profit in one month will reach 0.00001.202430 = 0.144. To achieve a profit of 14.4% per month, and RNG has n participants on average, the cost of running smart Contract C is n3500Gasprice + ccost. (ccost is the
