Bitcoin Mining Pool Tracker — Hashrate, Nakamoto Coefficient

What does Bitcoin Mining Pool Tracker do?

Bitcoin Mining Pool Tracker fetches live and historical Bitcoin mining pool data from mempool.space and computes network-level decentralization metrics including the Nakamoto coefficient, hashrate distribution, pool luck, geographic risk, and per-pool block share for Foundry USA, AntPool, F2Pool, SpiderPool, ViaBTC, and 12+ other pools. It supports configurable time windows from 24 hours to 3 years, letting you track mining pool dominance trends over any period. No API key is required.

Why use Bitcoin Mining Pool Tracker?

• Nakamoto coefficient computed automatically — the single most important decentralization metric (minimum number of pools that together control >50% hashrate) is calculated for you on every run without any manual data aggregation.
• Geographic risk analysis — pools are mapped to their home country (US, CN, JP, CZ, etc.) and the actor flags if any single country controls more than 50% of Bitcoin's hashrate — a regulatory and 51%-attack risk signal.
• Pool-level luck and trend tracking — pool_luck_pct compares actual blocks mined to statistically expected blocks, and pool_trend (growing / shrinking / stable) compares the selected period against the 7-day baseline.
• Flexible time windows — analyze the last 24h for daily snapshots or go back 3 years to study long-term concentration shifts; the same actor handles both use cases.
• Empty block and coinbase address monitoring — empty_block_rate_pct and coinbase_address_reuse_count expose pool operational quality signals that most block explorers do not surface.

Network summary record:

Field	Description
nakamoto_coefficient	Minimum pools needed to control >50% hashrate
top3_pool_concentration_pct	Combined block share of the top 3 pools (%)
decentralization_score	0–100 HHI-based score; 100 = fully decentralized
top_pool_risk	Largest-pool dominance risk: healthy / moderate / high / critical
pool_geographic_risk	Per-country hashrate shares and dominant country flag
solo_vs_pool_ratio	Estimated solo-mined vs pool-mined block breakdown
network_empty_block_rate_pct	% of recent blocks with ≤1 transaction
network_hashrate_ehs	Total Bitcoin network hashrate in EH/s
total_blocks	Blocks mined in the selected period

Per-pool records:

Field	Description
rank	Pool rank by block share (1 = largest)
pool_name	Pool name (Foundry USA, AntPool, F2Pool, etc.)
share_pct	Percentage of blocks mined in the period
hashrate_ehs	Pool hashrate in EH/s
empty_blocks	Number of empty blocks mined by this pool
empty_block_rate_pct	Percentage of this pool's blocks that were empty
avg_match_rate_pct	Average transaction match rate vs mempool
pool_luck_pct	Actual blocks / expected blocks × 100
coinbase_address_reuse_count	Times this pool reused a coinbase address
mining_revenue_per_ph	Estimated daily BTC earned per PH/s of hashrate
pool_trend	Trend vs 7-day baseline: growing / shrinking / stable

Cost estimation

Scenario	Frequency	Monthly cost
Daily snapshot (1 run/day)	30 runs/month	$0.15
Hourly monitoring (24h period)	720 runs/month	$3.60
One-off research (3y historical)	1 run	$0.005

All scenarios are billed at a flat $0.005 per run regardless of the period selected or number of pools returned.

FAQ

What is the Nakamoto coefficient and why does it matter? The Nakamoto coefficient is the minimum number of independent mining pools that together control more than 50% of Bitcoin's hashrate. A value of 1–2 indicates severe centralization and elevated 51%-attack risk; 6+ is relatively decentralized. This actor computes it automatically from the block distribution data so you do not need to sum shares manually.

Is the hashrate data real-time? The actor fetches live data from mempool.space's public API. For the 24h period, data reflects the last 24 hours up to the moment of the run. For longer periods, the API returns aggregated historical data.

Can I track a specific pool over time? Yes — schedule the actor to run daily or hourly, then filter the resulting dataset by pool_name. Use Apify's dataset API to export a time series for any pool's share_pct, hashrate_ehs, or pool_luck_pct.
