Introduction
What Velic is, the guarantee it makes, and who it is for.
Velic is a SaaS that preserves video master files and gives you continuous, independently verifiable proof that each master is still present and bit-intact, without having to trust the custodian holding it.
You upload a master through a normal web application. Velic encrypts it in your browser, splits it into content-addressed pieces, and stores it on the Filecoin Onchain Cloud. The network then produces continuous on-chain Proof of Data Possession (PDP), and Velic surfaces that as an auditor-ready proof-of-preservation dashboard and a downloadable certificate. When you need the file back, Velic restores the full master on demand.
Verify, don’t trust.
Traditional archives (LTO tape, cloud cold storage, preservation suites) rely on self-attested integrity: the same party that stores your data also vouches that it is fine. Velic replaces that with proof anyone can check on a public blockchain. A valid proof is evidence, not a promise.
Who it is for
Velic is built for organisations that hold irreplaceable moving-image masters and must be able to demonstrate, to auditors, insurers, funders, or their own boards, that those masters are intact:
- Film and television studios
- Post-production houses
- Media libraries and estates
- Cultural and regulated archives
What Velic does
- Resumable upload of large master files, encrypted in your browser before any piece leaves your machine.
- Asset library that identifies masters by thumbnail frames and technical metadata (codec, resolution, duration).
- Proof-of-preservation dashboard: stored-since, independent copy count, last-verified, and the on-chain PDP proof history per master.
- Downloadable preservation certificate whose proofs anyone can re-check on-chain.
- Full-master restore: pieces retrieved directly from providers, verified against their content addresses, reassembled and decrypted.
- Provenance (light): if a master arrives with a C2PA / Content Credentials manifest, Velic preserves it, displays it, and runs a basic validity check.
- Retention policy: a per-workspace soft policy recorded against each master.
