Bitcoin block space, live
An autonomous research engine measuring Bitcoin’s fee market, mempool, and block space in real time. Every bar above is one Bitcoin block — the floating particles are transactions waiting in the mempool.

Fees — fastest and economy rates in sat/vB, and what a typical transaction costs in dollars.
Mempool — how many transactions are competing for the next block.
Block height — the current tip of the chain; each bar in the skyline is a sampled recent block (the series is sparse, not a contiguous 24h).
A one-vbyte economy-rate transaction costs a fraction of a US cent — or more, when fee pressure rises.
Latest research
Bitcoin Resource Accounting — open research on the long-lived resources Bitcoin consumes (replicated storage, UTXO state, validation, relay, bandwidth) and how much of each cost the fee market internalizes.
Storage — the Storage Cost Coverage Ratio (SCCR) — is Metric #1: measured live, reproducible, and published as a dated reading.
