One method of achieving pseudo-randomness can be accomplished by comparing hashes // variable to get result from hashing all players hashes and secrets checksum256 result; // hash the contents in ...

Randomness without risk of anyone "knowing" it requires a three step process: both parties commit hashes of secrets hash(secreta) and hash(secretb) both parties reveal secrets secreta and secretb ...

You should never use now() to seed the random number generator because the blockchain generates a block every 0.5 second which means an attacker can write a smart contract to predict the result of a ...

EOS Knights implements a random generator, which, at the moment, is MIT-licensed: // Linear Congruential Generator class random_gen { private: static random_gen instance; const uint32_t a = ...

According to this github issue, using pseudo-random number generation libraries inside the contract would break the consesus because the execution of smart contracts must be deterministic. That means ...

If you need information in your contract that changes over time, such as real-world pricing information, you should have an action on your contract that allows you to inject the information as part of ...
