Local-first by design
Keep original documents, source code, recordings, and research where they belong: in your custody.
VERIFIABLE EVIDENCE OF ORIGIN
Great ideas
deserve evidence.
Your inventions. Your creations. Your discoveries. Preserve a verifiable history of what existed, when it existed, and who made a claim about it, without handing over your work.
Your original files stay on your device. Only cryptographic evidence is anchored.
01 / Public verification
Trust the evidence. Verify it yourself.
Look up a public record commitment and see where it is anchored. No account needed.
Try a real public example: . The lookup asks the iptrust API where a record is anchored.
01 / Record lookup
Enter a record hash to ask the public iptrust verification API whether an anchor is reported. An API response is not, by itself, independent blockchain validation.
02 / Independent verification
A complete evidence package lets software check the record encoding, commitment, signatures, anchoring transaction and inclusion proof against public block headers, without relying on iptrust's servers.
03 / Your files stay yours
A record commits to your files with a secret value that never leaves your device, so an anchor reveals nothing about content that could otherwise be guessed. Opening it later is your choice.
04 / Know what is shown
An anchor shows that a committed record existed by a given time. It does not decide legal ownership, inventorship, or the exact moment of creation.
02 / Built on principles
Privacy without compromise.
Evidence without permission.
A different approach to preserving the story behind what you create.
Public-chain anchoring
Records are anchored on public blockchains, creating tamper-evident reference points on more than one chain.
Independent verification
Portable evidence packages can be checked by an offline verifier, even if the platform goes away.
Creative provenance
Record the progression from early notes to experiments, revisions, prototypes, and final works.
Attributable statements
Link cryptographically signed claims to the work they describe, keeping claims distinct from established facts.
Share selectively
Reveal evidence when needed without publishing the underlying files or every detail of your work.
03 / The protocol
From inspiration to evidence.
Four stages, designed to give creators control over their history. Public registration is coming soon.
01
Create freely
Write, code, design, record, research, invent. Your source material stays yours.
02
Generate a record
Produce a cryptographic commitment and capture signed statements about the work.
03
Anchor publicly
Commit the record to public blockchains for a durable reference point.
04
Verify anywhere
Use a portable evidence package to reproduce and check the evidence independently.
04 / More than a timestamp
Every breakthrough
has a beginning.
A verifiable timeline can help tell the story of the work, not just its final result.
DAY 01 · ORIGIN
The first idea
Initial concept, handwritten note, sketch, or research question.
DAY 07 · DEVELOPMENT
The working theory
Experimental results, derivations, early code, creative drafts.
DAY 21 · VALIDATION
The independent review
Signed observations, feedback, test logs, and revisions.
DAY 45 · RELEASE
The published work
Final document, software release, composition, or invention disclosure.

THE NEXT CHAPTER OF PROVENANCE
Your work is yours.
Your evidence should be, too.
iptrust is preparing a private-first way to preserve the history of creative and inventive work. Public record verification is available to explore today.
