A useful explanation of how pending transactions influence fee opportunity must connect terminology with evidence. Here, the evidence is organized around fee rates, block space and transaction selection.
Pool statistics describe submitted work and payment rules; blockchain statistics describe accepted blocks and network consensus. Confusing these layers leads to incorrect conclusions about shares and rewards.
Fee Rates
Use fee rates as a testable input, not a general description. Record what produced the value, the interval it covers and any exclusions. Compare the record with block space only after both use compatible boundaries; otherwise the apparent difference may come from definitions rather than performance.
- Evidence: a dated record for fee rates.
- Cross-check: compare it with block space.
- Review trigger: repeat the check after a material change affecting fee rates.
Block Space
Treat block space as one layer of the system. Ask who controls it, how often it changes and which record can verify it. Its connection to transaction selection should be explained explicitly, because two correlated values do not automatically prove that one caused the other.
- Evidence: a dated record for block space.
- Cross-check: compare it with transaction selection.
- Review trigger: repeat the check after a material change affecting block space.
Transaction Selection
Evaluate transaction selection with a small evidence chain: source, timestamp, unit, boundary and calculation. Follow the same chain for fee rates. This prevents a precise-looking result from combining incompatible observations and makes future updates less dependent on undocumented assumptions.
- Evidence: a dated record for transaction selection.
- Cross-check: compare it with fee rates.
- Review trigger: repeat the check after a material change affecting transaction selection.
How pending transactions influence fee opportunity: evaluation sequence
- Write the exact decision involving fee rates.
- Collect block space using the same observation period.
- Test how the conclusion changes when transaction selection moves.
- Save the source values, conversions and date of review.
