SEIF

Quickstart

Install the SEIF CLI, initialize a workspace, and sign your first verifiable artifact in under a minute.

This guide takes you from zero to a verifiable, signed artifact. It assumes a POSIX shell; no specific operating system or machine is required.

1. Install the CLI

curl -fsSL https://get.seifprotocol.com | bash
seif --version

2. Initialize a workspace

Run this inside any project directory. SEIF creates a .seif/ store that holds your memory modules, signing keys, and governance records.

seif init

Portable by design

Throughout these docs, $SEIF_CONTAINER_ROOT refers to the root of your workspace — wherever you ran seif init. Nothing here depends on a specific path, hostname, or machine.

3. Sign your first artifact

echo "Hello, provenance!" | seif sign

This returns an Evidence URL. The artifact now carries an Ed25519 signature, a SHA-256 content hash, and an OpenTimestamps anchor.

4. Verify it

seif verify <evidence-url>

Expected output:

✓ Signature   VALID (Ed25519)
✓ Timestamp   OpenTimestamps anchored
✓ Hash        sha256:…
✓ Class       PUBLIC

5. Persist context

Add a decision to memory so your next session — on any machine, with any model — starts with it already loaded.

seif contribute decisions "Use Ed25519 over RSA: smaller keys, faster verify."

Introduction

SEIF is an open protocol that gives AI work persistent memory, cryptographic provenance, and auditable governance.
