Anchor W&B artifacts to Bitcoin. Zero-touch provenance for ML experiments.

umarise-wandb

Anchor W&B artifacts to Bitcoin. Zero-touch provenance for ML experiments.

pip install umarise-wandb

Quick start

import umarise_wandb

# Enable once. Every artifact is anchored automatically.
umarise_wandb.enable()

That's it. Every wandb.log_artifact() call now anchors the artifact to Bitcoin in the background.

Explicit anchoring

import wandb
import umarise_wandb

with wandb.init() as run:
    artifact = wandb.Artifact("my-model", type="model")
    artifact.add_file("model.pt")
    run.log_artifact(artifact)

    # Anchor explicitly
    results = umarise_wandb.anchor_artifact(artifact)
    # results[0]["origin_id"] -> UUID

Anchor a previously logged artifact

results = umarise_wandb.anchor_logged_artifact("my-model:v3")

What happens

1. File is hashed locally (SHA-256). Bytes never leave your machine.
2. Hash is submitted to Umarise Core API.
3. Umarise anchors to Bitcoin via OpenTimestamps.
4. origin_id is logged to your W&B run summary.
5. Within ~2 hours, proof is confirmed on the Bitcoin blockchain.

W&B metadata written

Key	Location	Value
umarise/origin_id	Run log	UUID
umarise/anchored	Run log	true
umarise_anchored	Run summary	true
umarise_last_origin_id	Run summary	UUID

Environment

Set UMARISE_API_KEY or pass api_key= to any function.

export UMARISE_API_KEY=um_your_key

Design principle

umarise-wandb never breaks your training pipeline. If anchoring fails (network, API), it silently continues. Your experiment always completes.
