How Does the Stratum Protocol Handle the Adjustment of the Pool’s Share Difficulty?
The Stratum protocol handles share difficulty adjustment through a command sent from the pool server to the mining client. The server can dynamically change the difficulty target for a specific miner based on their reported hash rate (vardiff).
The miner's software then adjusts its work submission criteria to match the new, pool-defined target difficulty, ensuring a steady stream of shares for accurate tracking.
