Pluto
A cryptographic stack that makes physical-world sensor data mathematically verifiable — by anyone, without trusting anyone.

StageProof of concept
The problem
Every sensor on earth
is trusted because
someone said so.
Not math. Not proof. Not evidence.
A paper you sign. An email. A human vouching for a number.

That is the entire chain of trust for physical data.
Three ways it fails
The data can be changed.
And no one would know.
01 / ALTER
Edit a number
Sensor readings sit in spreadsheets and databases with admin access. Change a value — no audit trail. No alarm. No proof it ever happened.
02 / DELETE
Delete a record
Remove a bad reading. The gap is invisible. Nobody knows 1,448 readings existed if only 1,447 are shown. Auditors check what they're given.
03 / BACKDATE
Fake the timestamp
System clocks are software. Software lies. Set the clock back, re-log the reading at any time you choose. Undetectable without external verification.
Pluto
What if sensor data was
impossible to fake
by design?
ECDSA signed in silicon
Hash chain — deletion visible
Roughtime — clock spoofing detected
Merkle Root on Solana
MicroSD physical black box
Architecture
Nine layers.
One chain
nobody can break.
Each layer enforces a property the layer above cannot override. Append-only. Counter-locked. Publicly witnessed.
01
Secure Measurement
Tamper-sealed sensor + hardware RTC + Roughtime oracle cross-check.
02
Cryptographic Seal
MCU builds payload: Raw Data + Timestamp + prev_hash + seq_no. ATECC608A signs in silicon — key never leaves chip.
03
Edge Transit
Signed, chained packet sent over LoRa to Gateway.
04
Split Save
Gateway writes simultaneously to encrypted MicroSD and cloud SQLite buffer.
05
Cloud Ingestion & Sequence Check
The Bouncer verifies signature + hash chain + exact seq_no. Invalid packets rejected.
06
Edge Rollup
11:59 PM — Gateway hashes all readings into a 32-byte Merkle Root, signed by ATECC608A.
07
Direct-to-Chain Anchor
Hardware posts Master Signed Merkle Root to Solana via HTTP. No intermediary.
08
Cloud Synchronisation
Cloud reads Solana to confirm anchor. Dashboard shows "Data Verified."
09
Trustless Audit
Auditor re-hashes data, checks public chain. Or physically pulls the MicroSD Black Box.
Live demonstration
One reading. Nine layers. Public ledger.

Why deletion is impossible
Delete one reading.
The entire future chain breaks. Instantly. Mathematically. Visibly.

The long view
What Oracle did for
banking data, Pluto does
for physical data.
Every sensor in the world produces data someone needs to trust. Right now that trust is human. We are making it mathematical.
