About
The atlas, not a pool
A reference atlas (EN / ES / RU) of the 160 P2PKH addresses funded 15 January 2015: labeled catalog, history, and search math, with dated snapshots and named other maps of the same ground.
What this site is
What this atlas publishes: a labeled catalog of the 2015 set, history, and search math.
Not a pool
No shared ranges, no cut, no token. btcpuzzle.info is a solo pool with ads and a BCPZ token. A share in a pool is not the UTXO. This atlas is not that pool.
Not a marketplace
Nothing is listed, priced, or sold. No accounts. Exchange colors, if any, are not an exchange.
Honest math
Expected value on remaining high puzzles is usually negative. We say so. Calculators on this site are educational. They do not promise a find.
How evidence is labeled
Every public claim in this atlas carries one of these labels. Missing evidence is a documented gap, not a silent fact. Forum chronology is not signed identity. Cryptographic consistency is not on-chain freshness.
On-chain
Observable on the chain. Cite a transaction or an explorer read with a retrieval date.
Cryptographically verified
The published scalar matches the compressed public key and the P2PKH address. That check is offline. It does not date a spend.
Forum statement
A forum claim, with a permalink when we have one. Not a proof.
Self-attribution
Someone signed or declared they were the finder. The name is labeled. The spend, if any, is on-chain separately.
Community report
Rumor or report, not verified here.
Speculation
A narrative. Not a fact.
Refuted
A circulating claim that does not survive the math.
Mix-up
A different object treated as this catalog.
Method
Generic algorithm or public-tool description, without private product names.
Snapshot
An explorer or third-party page plus an ISO date. Snapshots go stale. We date them instead of pretending they are live.
Update limits
This atlas is a dated reference, not a chain indexer. Limits, once:
Catalog status and nominal remaining allocation come from the 2 October 2026 catalog re-check. verifiedOn is that stored date, not the clock on the reader's machine. Source record snapshots remain 22 August 2026 and 27 August 2026.
On-chain spot-checks of listed historical transactions were read from mempool.space REST on 2026-09-11. On 2026-10-02 the catalog verify path was re-run: none of the 77 catalog-unsolved addresses had lost its reward (balance below half the nominal amount), and the first reward spend of all 83 solved records was read and cross-checked on a second explorer. Neither pass is a full UTXO census of all 160 addresses.
A later spend can move coins without this prose updating. Open an explorer for a live balance. This site does not run automatic external balance queries in editorial copy.
A spot-check is not a claim that every sentence is verified. We never claim 100 percent verification after a sample.
Other maps of the same ground
Cited, not copied. An atlas names the other charts. Retrieval below is 2026-09-11 unless noted. Failure modes are one line each. This site is a reference atlas, not a product catalog.
BitcoinTalk #1306983
Original thread. Public discovery, December 2015 on the forum clock. Primary forum record. Not a catalog.
privatekeys.pw
Addresses, hex ranges, published keys. A dump, not an atlas: no source labels, no search math. Body not extracted in the 2026-09-11 editorial spot-check; keep as a dump citation, not as a source of dates. Dates there are sometimes leak dates, not spend dates.
secretscan.org
Solved keys and dates in a single table. Useful cross-check. No hunt math. Failure mode on 2026-09-11: solved count still showed 79, behind this catalog snapshot. Also ships WIF and paste calculators; this atlas does not.
btcpuzzle.info
Shared range scanning, ads, BCPZ token. A pool with a puzzle list. Not a reference. Failure mode on 2026-09-11: home still showed 79 solved.
privatekeyfinder.io
Random-key tester on the 160 addresses. A hunting gadget, not a map. 2026-09-11 characterization: 83/77 display and a random-key hunter. Kind is correct; do not treat the gadget as a census.
