Finding actual blocks is too rare to measure individual contribution, so pools assign easier targets: hashes good enough to prove work but not to solve a block. Each accepted share credits your account; when the pool finds a real block, rewards are split according to shares submitted.
Monitor your accepted vs rejected/stale share ratio: rejects above ~1–2% usually indicate network latency, unstable overclocks, or pool-side issues, and translate directly into lost revenue.
