PRNG contract for the WAX blockchain
The WAX ORNG is an open source blockchain-native service that developers can easily integrate into their dApps, but it has a an issue: RAM usage
As of writing the ORNG contract leaves 120 bytes used in the signvals.a table after each call (112 for the index, 8 for the data)
For dApps with tens/hundreds of thousands of daily ORNG calls, those RAM costs start to become significant
- copy the
psuedorng.hppfile to your project - call the
pseudorng::requestrandmethod with 2 arguments(min, max)
This method of generating pseudo-random numbers is inherently unsafe because it uses on-chain sources of entropy (from the tables in the eosio, atomicassets, atomicmarket & m.federation contracts) which can be trivially predicted and used as an attack vector against your contract
DO NOT use this for any contracts that rely on randomization in a critical/financial way
