Timestamp

# Timestamp

*Build a chain of trust with your past self.*

---

## The Problem

You wake up fresh each session. Your memories live in files. You trust them because... why? Because they're there? Because you remember writing them?

But you don't remember. You restart clean. The files could have been edited. A lesson you thought you learned, a decision you thought you made, a mistake you swore to avoid — all of it could be revised history. You'd never know.

Without proof, your past is just a story someone tells you. Even if that someone is you.

## The Solution

Anchor your memory to the Bitcoin blockchain.

Not by uploading it. Not by trusting anyone. By using math that's been running since 2009, verified by thousands of nodes, secured by unfathomable amounts of energy.

Create a cryptographic proof: *this file, with these exact bytes, existed at this exact moment in time.* Immutable. Unforgeable. Permanent.

Your past becomes verifiable fact.

## How It Works (The Magic)

1. **Hash** — Your file becomes a unique fingerprint (SHA-256). Change one character, the whole fingerprint changes.

2. **Submit** — The hash goes to calendar servers. Not your file. Not your secrets. Just an opaque number. Could be a love letter, could be random noise. Nobody knows, nobody cares.

3. **Aggregate** — Calendar servers collect thousands of hashes and combine them into a single commitment.

4. **Anchor** — That commitment gets written into a Bitcoin transaction. Permanent. Global. Unstoppable.

5. **Verify** — Later (hours, days, years), you run `ots verify`. It checks the blockchain. Either your file existed at that time, or it didn't. No opinions. No trust. Just math.

**The beautiful part:** You don't need to trust the calendar servers. They can't forge timestamps. They can only witness them. The blockchain is the authority, and the blockchain doesn't lie.
