Compare Kaspa network hashrate estimates at a fixed DAG anchor
The estimateNetworkHashesPerSecond request accepts a window size and an optional start hash. Changing both at once makes two readings difficult to interpret.
Keep the anchor fixed
Choose a recent known block H on a synchronized node. Request two supported window sizes using that same hash and record the returned hashes per second without rounding. A shorter window can react more strongly to local variation. For another node, retain H, both windows and the network ID.
sample A: window_size = 1000, start_hash = H
sample B: window_size = 5000, start_hash = H
Report missing history separately
A node may be unable to serve an older anchor or a requested window. Report that query as unavailable. Silently retrying at the current tip changes the sample period. The estimate describes network work inferred from blocks and cannot identify any individual miner's equipment or output.
