The Randao random number generator info
  • Say, you are running a raffle draw at the office party. 
  • Instead of picking the name of the winner from a box, you assign each party-goer a number 1, 2, 3...20 (up to the number of party-goers), and have each of them provide a random 3 digit number.
  • You sum all the 3 digit numbers, divide the sum by 20 and the remainder+1 is the winning number (the remainder+1 will always fall between 1 and 20).
  • With this approach, an auditor could mathematically verify the draw by asking each party-goer the number he or she submitted and re-calculating the remainder.
  • Such a retrace wouldn't be possible if a lot was drawn from a box. 
  • If the numbers submitted are recorded in a blockchain, the party-goers need not remember the number they submitted, the numbers are in the blockchain, tamper-resistant.
  • Beyond gaming, lotteries have applications such as an alternative to first-come-first-served queuing for tickets for a blockbuster event.
