Lightning nodes need to open channels (on-chain tx). Every channel open creates UTXOs that live in every full node forever. Use this model to estimate your real storage cost contribution and how it compares to current fees. Adjust the sliders to match your setup — all parameters documented in the open-source model.
| Data Point | Source | Refresh | How It's Used |
|---|---|---|---|
| BTC Price | blockchain.info/ticker | Daily | Computes fee-to-storage ratio, sat/$ rate, inscription fee in USD |
| Fee Estimates | mempool.space | Daily | Fee bar chart, history trend, alert conditions |
| Mempool Size | mempool.space | Daily | Displays unconfirmed tx count — network congestion proxy |
| Block Height | blockstream.info | Daily | Block height display, BIP-110 signaling check via version bits |
| BIP-110 Signal | Derived from version bit 4 in last 25 blocks via blockstream.info | Daily | Tracks miner support for BIP-110 soft fork proposal |
live_data.json (current snapshot) and fee_history.json (rolling 14-day history) — both are public and open source.
