[Tech]Pseudorandom number generators (PRNG)

In the case of existing pseudorandom number generators (PRNG), the seed value can be traced with encryption patterns.

Compared with pseudo-random number generation mechanism, QRNG that uses quantum mechanical uncertainty can be regarded as more legitimate RNG, and therefore ReapChain uses such QRNG to enhance the security required during its consensus processes. When the technologies make further advancements, consensus processes on blockchain may require Proof of Randomness (PoR), to perform someday.

While quantum random numbers have encrypted by using public keys of each candidate node selected through the quantum random number before being distributed on a blockchain network,only those nodes that have chosen as the steering committee candidate group can decrypt and view the quantum random number by using their private keys.

The decrypted content includes public key and coordinator information that has selected through the use of the quantum random number. By this information, the quantum random number is encrypted and delivered to the coordinator through racing. The coordinator compares quantum random numbers for each node of the steering committee candidate group previously received from Qmanager to verify the integrity of the selected candidate group.
