Proof check
Chapter 4 — Chipotle Mexican Grill (CMG)
This chapter's exact text was locked into Bitcoin block #969,201, mined on September 29, 2026 at 9:04 PM UTC. That means it already existed by then and hasn't changed since — proven by the Bitcoin network, not by us. Anyone who tried to backdate or edit it would produce a different fingerprint that wouldn't match this block.
How this was checked
We did the work for you — but every number below is public, so you can re-check each line yourself.
- 1 · The proof is for this exact chapter
The chapter file has a unique SHA-256 fingerprint. It matches the fingerprint recorded inside the timestamp proof — so the proof can only belong to this text, unchanged.
- The file's fingerprint
b0f90d486510bbd882de0dfd77fc3163ba0d3161b42e751b5e9166263d974823- Fingerprint inside the proof

- 2 · The proof is anchored in a real Bitcoin block
The proof resolves to a Bitcoin block's merkle root — the fingerprint of everything in that block. It matches the merkle root of the real block #969,201 reported by an independent explorer — so this proof genuinely lives in that block.

- 3 · When Bitcoin says it happened
Block #969,201 was mined on September 29, 2026 at 9:04 PM UTC — the blockchain's own clock, which no one can rewind. So this chapter provably existed by then.
A note on the time: we show it in UTC — the fixed, universal clock used for proofs. A block explorer like mempool.space usually shows the same moment in your local timezone, so the clock time can look a few hours different. It's the exact same instant.
