A story. A puzzle. A wallet.

The Book

Naka-Toshi begins as literature.

Twenty-one digital volumes, released one by one, each written to be read before it is solved.

The prize may pull you in. The story must keep you there.

The Puzzle

Puzzles buried inside the prose.

Inside each book, clues are hidden — not placed on top of the text. Buried inside it.

You read. You notice. You compare shadows.

The Bitcoin

At the end waits a real wallet.

The encrypted seed is protected by a key derived from all 21 discoveries using public cryptographic methods.

No drawing. No chosen winner. Whoever solves it first, unlocks it.

The Mechanism

The prize is not promised.

It is locked.

The encrypted seed lives where it can be verified.

The wallet address will be public. The balance will be visible on-chain.

The decryption path will be open enough to inspect, but not open enough to spare you the reading.

The author cannot simply pick a winner.

The reader must find the key.

The Circle

The circle forms before the first book opens.

The first names are being inscribed.

Book 1 is approaching.

The ones who arrive early will remember when the room was still quiet.
