ONE LINK. A FIRE THAT TRAVELS.

How far did
your spark travel?

You pass the fire to someone. They pass it on. Follow the chain of first burns that began with your link.

Burn your first note to start your own chain. No account needed.

How a new Ember counts

Share your personal link. When a new saved browser burns its first note from that link, your total rises by one. Repeat burns and your own browser do not count. These are browser IDs, not verified people: cleared storage and other browsers can affect totals. An Ember # is a permanent serial number, not a live count; retired numbers are never reused. All-time ranking, refreshed about every 2 minutes; ties go to the earlier Ember number. You may publish a nickname and photo, or stay anonymous. Profiles are self-submitted, not verified identities. No prizes or payments for referrals.

FIAT FADES. THE FIRE REMAINS.

One fire.
Everyone’s sparks.

The live BTC/USD price controls the scale and intensity of the flames. Market activity lifts sparks; every newly detected Bitcoin block releases a short flare. A live BTC/USD calculator sits close by when you want a number instead of a flame.

The note is fictional. Your first counted burn gives this browser an Ember. Pass its personal link to a friend: their own first burn can add one Spark to your chain, and they can pass theirs along. Repeat accepted burns still move today’s and all-time totals.

A LITTLE PERSPECTIVE · NO WALLET NEEDED

One human.
Twenty-one million.

If all 21 million bitcoins were shared equally between 8.3 billion people, each person would get about 0.00253 BTC. Enter your amount to see how many of those equal shares it represents. This is a thought experiment, not a ranking of holders.

How to calculate your percentage of Bitcoin’s supply ↗

Your amount stays in this browser; it is not sent or saved. Population is a rounded 2026 estimate, not a live count; 21 million is Bitcoin’s eventual ceiling, not today’s issued supply. UN population data ↗ · Bitcoin supply ↗

BITCOIN BEYOND THE PRICE

Three ideas hiding
inside the protocol.

One network, three very different uses. Explore the idea here, then follow the original documentation.

01 · TIMESTAMPING

Prove when a file existed.
Keep the file private.

A file fingerprint can be combined with others into a Merkle commitment anchored to Bitcoin. The proof establishes a timestamp—not whether the file’s claims are true.

Understand the proof →OpenTimestamps ↗

02 · TIMELOCKS

Make recovery wait
for a future block.

Bitcoin scripts can delay a spending path until a block height or time. That can support a carefully designed recovery plan; a demo is not a wallet or a safe inheritance setup.

Try the block-delay lab →Read BIP 65 ↗

03 · LIGHTNING

Pay for one API call.
Not a whole plan.

L402 pairs a Lightning invoice with an access credential: an API can charge per request instead of demanding a conventional subscription. This is an application pattern, not a Bitcoin base-layer feature.

CLEAR ANSWERS · NO HYPE

About the Bitcoin fire.

What is BTC Campfire?

Free interactive browser art. Live BTC/USD changes the flame, Bitcoin blocks trigger a flare, and the fictional note gives every visitor something simple to do.

Does the note burn real money?

No. The banknote and burn are visual only. No wallet is connected and no transaction is created.

How do the counters work?

Today and all-time count accepted burns, including repeats. Unique burners count a saved anonymous browser once, not verified individual people. A separate limit on new browser identities reduces rapid repeat sign-ups without storing IP addresses as identities.

Is the Crowd Pulse a prediction?

No. It is one anonymous mood vote per saved browser per UTC day—not investment advice, a price target or a trading signal.

What is BTC dominance without stablecoins?

It is Bitcoin’s market cap divided by the tracked crypto-asset market cap, excluding wrapped representations to avoid counting assets twice. The optional view also removes the stablecoin category. These are CoinSpectrum estimates: its coverage may differ from other providers, data may be delayed, and neither number is a trading signal. Data: CoinSpectrum ↗
