BTC Difficulty Pulse

Keyless Bitcoin block-health pulse (public mempool.space v0 + blockstream.info fallback, no key): block cadence, tx count, difficulty drift, coinbase, reorg detection via previousblockhash links, stateful KVS deltas. Read-only public data.

Keyless Bitcoin mining-capacity pulse (mempool.space, no API key): current network hashrate, 24h/7d capacity trend %, last difficulty + last retarget delta from the hourly hashrate series. Stateful KVS baseline on first run; alerts on 7d hashrate growth >10% or 24h capacity drop >5%.

Keyless Bitcoin network-state monitor (no API key, no mining): live hashrate vs the multi-day trend, next difficulty retarget preview (change %, remaining blocks, ETA), and the fee ladder - with deltas vs the previous run when scheduled (stateful KVS). One compact pulse item per run.

Keyless Bitcoin mempool + fees monitor (mempool.space, no API key): mempool depth (tx count, vsize, total fee), fee tiers, recent block cadence, 60m hashrate. Stateful KVS: repeat runs report mempool drift + fee-tier shifts; alerts on fee-spike / mempool-surge / hashrate-dip.

Keyless Bitcoin P2P node-census pulse (public Blockchair nodes route, no key): node count, client-version mix, geo distribution, tip-lag delinquency, run-over-run KVS deltas with node/version/geo churn alerts. Read-only public data.
