How Provlyn works
Your intellectual property deserves more than a PDF certificate. Provlyn creates a permanent, legally recognised record anchored to three independent proof systems — RFC 3161 timestamps, the Bitcoin blockchain, and optional eIDAS qualified seals.
01
Create your vault
Private and cryptographically protected. Nobody — including Provlyn — can open your vault without your key.
02
Deposit your IP
SHA-256 hashed on your device before upload. Store the encrypted file with us, or keep only the hash.
03
Anchored & certified
RFC 3161 and Bitcoin on every deposit, with an optional eIDAS qualified seal and a court-admissible certificate.
04
Share with proof
Invite recipients and every access lands in an immutable log. Watermark what they open, so a leak traces to one person.
Who uses Provlyn
Anyone who creates something valuable and needs to prove they created it first.
Designers & artists
Your work, timestamped before you share it.
Upload your design files before sending to a client or posting online. If someone copies your work, you have cryptographic proof you created it first — dated to the second.
Founders & startups
Protect your idea before the pitch.
Deposit your pitch deck, business plan, or source code before investor meetings. The access log shows exactly who you shared it with and when.
Writers & musicians
No lawyers needed to prove authorship.
A manuscript, a track, a screenplay — deposit it once and Provlyn anchors it to two independent legal proof systems simultaneously. Court-admissible from day one.
Research & academia
Establish priority on your discoveries.
In research, who got there first is everything. Deposit your findings as you work. RFC 3161 timestamps are already recognised in UK, EU, and US legal frameworks.
Why Provlyn
The only IP protection product combining a vault, legal timestamps, blockchain anchoring, and an immutable access log.
Immutable access log
Every time your vault is accessed — by you or anyone you share it with — the event is recorded permanently. Timestamp, IP address, action. This is chain of custody evidence. This is only offered by Provlyn.
Triple-layer proof
SHA-256 cryptographic hash on your device. RFC 3161 timestamp from a trusted authority — recognised in UK, EU and US courts. Bitcoin blockchain anchor via OpenTimestamps. Three independent layers of irrefutable proof.
A vault, not just a certificate
Your IP lives in a permanent, organised vault. Every version. Every deposit. Every certificate. Accessible whenever you need it, with a complete history of everything deposited.
Shareable with access control
Share a vault with investors, lawyers, or partners. They get a link and a separate access token. Every action they take is logged. You always know exactly who saw what and when.
Legal precedent
“In March 2025, a court in Marseille recognised blockchain timestamps as valid legal evidence — the first such ruling in the EU.”
RFC 3161 timestamps are already recognised in UK, EU and US courts under eIDAS and equivalent frameworks.
