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

the validation is done n/k times. ）。Let's define the negligible probability Pn as the probability of obtaining a, SHA3 collision (i.e. the hash ethereu M is built upon): 1/2^128. To honor the Ethereum security requirements, we need to choose the minimum chain length N (below which we veriy every head ER) and Maximum K verification batch size such as (1/k) ^ (n/k) We define the probability that the negligible probability PN is to obtain a 256-bit SHA3
