A "Roshtein seed" likely refers to the concept of a "seed" in online gambling or gaming contexts, especially related to provably fair algorithms used by some online casinos. A seed is a portion of a complex algorithm that involves mathematical processes to determine outcomes in games or bets. In provably fair systems, seeds (including server seed, player seed, and nonce) are used to generate randomness in a way that players can verify fairness by checking the seed values and algorithm results. Roshtein is a well-known online casino streamer, so when people refer to a "Roshtein seed," it may mean the seed used in the random number generation algorithm during his gambling streams or games. This seed controls the fairness and randomness of game outcomes that viewers or players can inspect to confirm the results are not rigged. In summary:

• A seed is a value used in random number generation algorithms.
• In online gambling, it determines the outcome of bets or spins.
• A "Roshtein seed" references the seed used in games or streams involving Roshtein for fairness verification.

This understanding aligns with general definitions of "seed" in provably fair gambling systems. The biological definition of seed does not apply here in this context.
