01 — Ventures
The stack we own end to end.
From celestial engines to furniture-scale evidence rails — one company, one doctrine: commitments you can refute, never marketing green ticks.
Cosmic Time Stamp
CSTP seals on a 152-byte core. The core fixes a file’s fingerprint. A public beacon round sets the earliest time. When a timestamp authority answers, its token sets a latest time too. A check reads ✕ doesn't hold, ◇ holds up or ◔ not checked. None of these is a pass.
openstamps.com →OpenStamps
Evidence layer for timber and furniture supply chains — plot, harvest, mass-balance, unit seals — built for auditors and Dec 2026 enforcement pressure.
openstamps.com →Phoenix Ephemeris
Our high-precision ephemeris and sky-consistency stack — the celestial substrate behind Cosmic Time Stamp verification.
phoenixephemeris.com →SupaToot
A product in active build under the Protosonic umbrella.
supatoot.com →Software & tooling
Readers, seal pipelines, channel bots, and the systems that carry unit seals at industrial volume.
Made objects
Physical pieces alongside our software — including metal additive manufacturing and 3D printing.
02 — Intellectual property
Patent-pending technologies.
We file for what we invent. Two US provisional applications anchor the stack below — patent pending, owned by Protosonic OÜ.
Cosmic Time Stamp (CSTP)
Committed evidentiary artefacts with a three-outcome grammar — refuted, not-refuted, not-checked — proof entries, anchor policy, and offline readers designed for decades of durability.
Sky as a Signal
Ephemeris-conditioned attestation and sky-consistency limbs — celestial infrastructure for time and place claims that belong in evidence systems, not marketing astrology.
Doctrine we will not break: green never means “genuine.” Ephemeris supports consistency; unpredictable anchors carry not-before force. OpenStamps sells the evidence layer — operators still own their filings.
03 — Studio
Independent. Technical. Built to be checked.
Protosonic OÜ is a privately held Estonian company. We invent the formats, ship the products, and keep the doctrine tight — so a mill in the forest and an auditor in Brussels can disagree with the same bytes.
Founder-built, with serious IP and products that have to survive hostile readers. That is the point.
