Bitcoin scarcity,
ledgered.
The supply schedule is the only monetary policy that ships in code. Halving turns it into an API — query the issuance curve, stream miner rewards, and trace any coin back to the coinbase that minted it.
Four panes.
One ledger.
Subsidy curve, miner attribution, holdings rollup, fee market. Each pane is a first-class endpoint — render it, stream it, snapshot it. No CSV exports.
Four ways teams ship on Halving.
Issuance, halved every 210,000 blocks.
Halving exposes the issuance curve as a first-class object — query it, subscribe to it, render it. The next reward drop is locked in at block 1,050,000.
Tabular S2F at any historical block.
Compute stock-to-flow over any window — by block, by epoch, by date. Halving gives back the math, the methodology, and the source ranges in one response.
Subsidy + fees, per block, per pool.
Stream miner revenue as it lands — subsidy split from fees, attributed to the winning pool, with confirmation depth and reorg signal in the same payload.
Every coin, traced to coinbase.
Walk any UTXO back to the coinbase that minted it. Halving caches the path so your audit team gets the lineage in 8 ms, not eight hours.
Trustless
vs centralized.
Five places where on-chain provenance beats a quarterly PDF. The data is public — we just made it queryable in production.
“Halving was the first issuance dataset our auditors accepted without follow-up. The lineage receipts ended a three-week back-and-forth.”
Pricing,
without seats.
Pay for queries, not seats. Pay for streams, not viewers. No per-user pricing — your whole desk gets in for the same price.

On-chain mechanics.
Custody, reorgs, indexing cadence — answered for the auditor and the engineer in the same paragraph.
No. Halving never holds keys, never signs transactions, never custodies funds. It is a read-only index over the public Bitcoin chain — you bring your wallet, we hand back the data.
Recent blocks of work.
Block 1,050,000 — fourth halving cleared. Subsidy dropped to 3.125 BTC.
Coinbase lineage now resolves Taproot leaf paths in the audit response.
Miner reward WebSocket now attributes Antpool, Foundry USA, and ViaBTC outputs natively.
S2F endpoint now accepts arbitrary block ranges and returns flow components separately.
The supply schedule
is open. Connect a wallet.
No seat fees. No quarterly PDFs. The chain is the source of truth — Halving just made it queryable.
