WHAT IS BITTY?
BITTY•THE•BITCOIN•MASCOT is Bitcoin's open-source mascot — a character born on bitcoin.org, created by Spiral, and immortalized on Bitcoin Layer 1 as Rune #209,730. This is the full story: what a Bitcoin Rune is, where Bitty came from, and why 21,000 tokens now sit forever in Satoshi's wallet.
WHAT IS A BITCOIN RUNE?
Runes is a protocol for issuing fungible tokens directly on the Bitcoin blockchain. It launched in April 2024, at Bitcoin's fourth halving — block 840,000 — and works through Bitcoin's native OP_RETURN mechanism. That means no sidechains, no bridges, no wrapped assets, and no smart-contract platforms: every Rune transaction is a real Bitcoin transaction, secured by the same Proof of Work that secures Bitcoin itself.
A Rune is "etched" once — its name, supply, divisibility, and mint terms are written permanently into a Bitcoin block. After that, the protocol enforces the rules. Nobody can change the supply, freeze balances, or rewrite the terms. It is money-adjacent engineering with Bitcoin's guarantees.
THE ORIGIN: HERE COMES BITCOIN
The Bitty character was not invented for a token. He came first — as part of Here Comes Bitcoin, an open-source educational initiative by Spiral, the Bitcoin-focused organization inside Block, Inc. (founded in 2019 as Square Crypto, renamed Spiral in 2021). The initiative used lovable, grumpy, anthropomorphic Bitcoins to make Bitcoin friendlier and more accessible — and the characters ended up as a hidden easter egg on bitcoin.org itself, the oldest Bitcoin website in existence.
That declaration matters. Bitty belongs to no company. No copyright, no permission needed, no licensing fees — the character is a public good, exactly like the protocol he represents.
THE ETCHING: BLOCK 935,003
On February 4, 2026, BITTY•THE•BITCOIN•MASCOT was etched onto the Bitcoin blockchain as Rune #209,730. The same transaction inscribed Ordinal #118,247,453 — landing on a satoshi mined on May 24, 2015, during Epoch 1, when each block still carried a 25 BTC reward. The supply mirrors Bitcoin's own mathematics: 21,000,000 tokens, 8 decimals.
The public mint — 18,985 mints of 1,000 BITTY each, first come, first served — is now 100% complete. There was no pre-sale, no venture capital, no private rounds. 90.4% of the supply was minted publicly; 9.5% is a transparent founder reserve; and 0.1% is gone forever — which brings us to the best part of the story.
THE SATOSHI TRIBUTE
On February 9, 2026, 21,000 BITTY were sent to Satoshi Nakamoto's Genesis Wallet — 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa — the address that received the very first Bitcoin block reward in January 2009. The transaction cost ~$0.19 USD. Not a typo.
Since Satoshi disappeared and those keys have never moved, the tokens are mathematically inaccessible: an eternal, verifiable, on-chain tribute from a grumpy orange mascot to the anonymous mind that started everything. Every claim above can be verified independently:
FREQUENTLY ASKED
What is BITTY?
Bitcoin's open-source mascot from bitcoin.org, immortalized on Bitcoin L1 as Rune #209,730 — etched at block 935,003 on February 4, 2026, with a fixed supply of 21,000,000.
Is the mint still open?
No. All 18,985 public mints are complete. 21,000,000 BITTY are fully distributed on-chain. BITTY trades on secondary Runes marketplaces such as UniSat.
Who created the character?
Spiral (Block, Inc.) — for the Here Comes Bitcoin initiative. All assets were declared free of copyright on May 8, 2024. This project is not affiliated with Spiral, Block, or bitcoin.org.
Is there a roadmap?
No. Roadmaps are promises. What you see is what is on-chain — the protocol enforces what it enforces, and the community decides what comes next.
