Terms & Concepts
  • Pseudo-random number generator (PRNG): A software or hardware system that produces sequences of numbers approximating true randomness; weaknesses can compromise cryptographic security.
  • Private key: A secret cryptographic key used to sign transactions and access cryptocurrency holdings; revealing it allows full control over the associated assets.
  • Mining pool: A collective of cryptocurrency miners who share processing power and split rewards proportionally to contributed work.
