| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We propose N-choice game (NCG), a decentralized pseudo-random number generation method that can be executed on smart contracts. Of the M participants, one is a dealer, and the rest are players, each with a different role. Each participant chooses one value between 0 and N-1 and receives a score determined by the NCG rule. The amount of reward each participant receives is determined by the score. The values chosen by the participants are combined and hashed into a pseudo-random number. The NCG framework is designed to achieve the following three goals: (1) Incentivize participants to provide random choices, (2) Evaluate the level of randomness in the decentralized environment, and (3) Establish high performance. We implement the NCG framework in Solidity and evaluate its performance. Our extensive experiments reveal that unless more than 90% of NCG players collide, the generated random numbers have high randomness that can pass the NIST randomness test. The experiments also demonstrated that the throughput of random number generation in NCG is 129 times faster than in the existing framework, Random Bit Generator. | |
