Bitcoin earns every block with proof-of-work. Memecoins get a name and a ticker and nothing else. token22 makes coins earn their spot: every launch is stamped with real SHA-256 work against a live Bitcoin block, and every coin without a stamp lands on the Unstamped Board.
In 2022, a Reddit user on r/solana asked about Solana's new token program, Token22. Anatoly Yakovenko, Solana's co-founder, answered that it ships under a new program id, and added one line that stuck with us.
token22 is our answer to that line: a new kind of token, built by people outside Labs, that has to show real work before it counts.
“It's very possible that the next version of token ends up being built by someone outside of Labs.”
Bitcoin's first block is 80 bytes. Hash them twice with SHA-256 and the zeros appear, exactly as they did in January 2009. No company or explorer has to vouch for it. Your browser is checking it right now.
That's the standard token22 holds every coin to. Show the work, or go on the board.
“The Times 03/Jan/2009 Chancellor on brink of second bailout for banks”
These 80 bytes were hashed on this page, just now. The result has the zeros Bitcoin demanded in 2009, so the block proves itself.
Bitcoin is the only ledger that proves itself: every block carries the work that made it. Every token minted since then skipped the work. token22 puts them all on the board. Each one owes exactly one hash, and the debt stays open until someone pays it against a real Bitcoin block.
| Coin | Bitcoin hash on file | Status | Owes |
|---|---|---|---|
| Bitcoin the reference | its own, every block | Proven | 0 |
| $T22 not launched | at birth, once live | Pending | 1 |
| Wrapped SOL | none | Unproven | 1 |
| Every dog coin | none | Unproven | 1 each |
| Every cat coin | none | Unproven | 1 each |
| Whatever launched this morning | none | Unproven | 1 |
| Your bags | none | Unproven | 1 each |
Every coin launched on token22 is stamped before it exists. Your browser binds the new mint address to a fresh Bitcoin block with real proof-of-work, and the coin goes live on pump.fun with the stamp written into its metadata. It never owes a hash, not even for a block.
Example layout. Real stamps are made on the launchpad page.
Real Bitcoin block headers are fed to the program. Each one has to extend the last and carry valid proof-of-work, or it's refused.
Anyone can put any Solana mint on the Unstamped Board. From that moment it officially owes Bitcoin one hash.
Find a nonce that binds the coin to one of the six newest Bitcoin blocks, with enough leading zeros. The work is tied to your wallet, so nobody can copy it.
The coin flips to PROVEN, a receipt points at the Bitcoin block that saw it, and you're paid in $T22. That's the only way $T22 gets minted.
// the whole puzzle proof = sha256d("TOKEN22:STAMP:v1" || bitcoin_block || coin_mint || your_wallet || nonce) require leading_zero_bits(proof) >= bitcoin_block.zero_bits / 4
A proof needs a quarter of the leading zeros that its Bitcoin block has. A 2009 block has 32 zeros, so a proof against it needs 16. Today's blocks have around 78, so a proof needs 19. Proving never gets cheaper than Bitcoin lets it.
The reward follows Bitcoin too. Each proof pays 50 $T22 in era 0 and halves every 210,000 Bitcoin blocks. When Bitcoin halves, $T22 halves the same day. Each Bitcoin block can back 21 proofs.
“It doesn't matter who tells you a longest chain, the proof-of-work speaks for itself.”Satoshi Nakamoto, bitcointalk.org, 7 August 2010, in the thread “Bitcoin minting is thermodynamically perverse”
Later in that thread, the poster who started it changed his mind: “I am now inclined to think that bitcoin is in fact highly EFFICIENT rather than inefficient.” token22 takes it one step further: if proof-of-work speaks for itself, a coin without any has nothing to say.

Real SHA-256 against real Bitcoin blocks, on every core you lend it. You get a receipt you can verify yourself.
LaunchName it, stamp it with a Bitcoin hash, deploy it on pump.fun. Your coin never appears on the Unstamped Board.
BoardThe relay, the anchors and every proof, once live. Re-hash the first Bitcoin blocks yourself.
Anyone selling $T22 before a mint address appears on this page is not token22. $T22 can only be minted by the program, as a reward for a proof. Nobody can sell you any before then.
