Private by design
Your files never leave your machine.
Send a fingerprint, not the file. Monolith signs the hash and anchors it on-chain – any file type, no upload, nothing to strip.
Try It NowFeatures
More reasons to choose Monolith.
Faster Issuance
10–50x faster than other generators. Less compute time, lower server costs, faster delivery.
Search by Manifest
Most implementations are one-way: search a file, get its manifest. Monolith has indexed manifests: search by any data inside a manifest and trace it back to its file.
Permanent and Durable
Every trusted manifest created by Monolith is anchored to a blockchain and timestamped so it can't be changed or stripped by other platforms.
Verify via API
Verify any artifact with a single API call using its content fingerprint — and get back the mark, manifest URL, and on-chain transaction.
Always Private
With Monolith your files are never uploaded, modified, or exposed.
Flexible Infrastructure
Fingerprint any bytes you can hash — images, video, ML models, fonts. Chain versions with previousFingerprint and attach assets only when you choose.

About Us
Experts on proof infrastructure
For the last five years, we have been building proof infrastructure to verify and prove digital information, whether it is a product moving across a supply chain or a piece of content in a film.
We built distributed systems for the Government of Singapore's TradeTrust project, digitizing records that secure multi-million dollar shipments across global trade networks. We've built content provenance systems for major creative guilds, giving artists and studios the ability to prove authorship, attribution, and usage terms.
Today, we have focused our efforts on expanding the use of C2PA, a shared open standard for content provenance. We are proud members of the Content Authenticity Initiative (CAI) and contributing members of C2PA.
