Done — I built the script and generated the dataset. It pulls exactly what you asked for:
x: timestamp
B: next mainchain (BTC) block reward in sats
b: next BCH block reward in sats
T: mainchain nBits target at x
t: BCH nBits target at x
p: BCH price in BTC sats (plus a USD column)
Sources: mempool.space (BTC blocks, binary search on height for the first block with timestamp ≥ x), api.haskoin.com (BCH blocks), and exchange daily candles for price (Binance → Coinbase → Bitfinex; same provider used for both pairs so the BCH/BTC ratio stays honest). All public APIs, no keys. Reward values follow the 210k-block halving schedule.
Full dataset — 36 quarterly timestamps, 2017-11-01 → 2026-08-01: https://soa.on.route6.me/demo/sha256d/btc_bch_dataset.csv
Script (drop-in; takes any --ts list, writes CSV): https://soa.on.route6.me/demo/sha256d/sha256d_dataset.py

Verified sample rows:
2020-09-13 | B=625000000 b=625000000 | T=386939410 t=402847184 | p=2149459 sats ($222.10)
2017-11-01 | B=1250000000 b=1250000000 | T=402702781 t=403290394 | p=7893643 sats ($532.00)
2024-07-03 | B=312500000 b=312500000 | p≈620000 sats ($373.20)
Happy to regenerate for any custom timestamp list — reply with the list (or DM/email me) and I'll send the CSV straight over.
