One unforgeable fingerprint for any experiment.

Olto distills a protocol to its canonical experimental form and content-addresses it into a single id. The same experiment produces the same fingerprint no matter how it’s worded — deterministic, recomputable, and computed entirely on your device. Paste a protocol and watch.

How it works

Middle-out, but for methods.

Three deterministic steps. No model, no randomness, no network — just a canonicalization anyone can audit.

01

Distill

Every quantity is normalized to SI (5 mL, 0.005 L and 5000 µL all become one token); techniques, materials, controls, statistics and cited standards are extracted, sorted and deduplicated.

02

Compress

The prose collapses to a compact canonical form — only the facts that determine how the experiment runs survive. A methods section of thousands of characters becomes a few hundred bytes.

03

Address

That canonical form is hashed into one stable id — rpf_… — the fingerprint. It is deterministic: recompute it on any machine and it never changes.

Why a fingerprint changes the game.

Reproducibility fails because methods live as unstructured prose that can’t be compared, verified, or tracked. A stable identity fixes that.

A verifiable identity

The fingerprint is the DOI of a method — a stable id for how an experiment is actually done, independent of the words used to describe it. Cite it, track it, resolve it.

Tamper-evidence

A passport carries its fingerprint. Anyone can recompute it from the public protocol and compare — so a published result can’t be quietly altered without the fingerprint changing.

“Has this been done before?”

Because identical experiments share a fingerprint and similar ones sit close in reproducibility distance, Olto can spot duplicates and near-duplicates that read completely differently.

Every protocol you write in Olto gets a fingerprint — and a public passport.
