What's new.

New

The site that proves itself

obsign.io launched as a site where every claim is something your own machine re-executes:

• The Living Proof loop: a real provable denoiser on your photo, CPU and GPU bit-identical, signed and verified in-browser.
• The reproducible forensic examiner (two regimes, localized, calibrated, signed) and the unified Regime A+B report.
• The free verifier, the C2PA inspector, the WebGPU engine demos, and a WebXR coherence field.
• Docs, pricing, and this honest security model.

Verified

Real-browser and accessibility verification

The live proofs are verified on a real GPU and in a real browser, not just reasoned. The browser engine is confirmed bit-identical to the SDK, and the whole site passes a cross-browser pass on Chromium, Firefox, and WebKit with a clean accessibility audit.

New

Accountable computation & provable inference

Deterministic integer inference whose output you can prove and re-run, paired with the accountable layer: the original preserved, the exact diff receipted, reversible bit-for-bit, with coherence and invention maps. Tiered so any model fits (A bit-exact, B reproducible, C accountable).

New

The platform, v1.0.0

The first release of Obsign: the substrate engine (bit-identical across six substrates), re-runnable cryptographic receipts, the forensic edition, video provenance, the OFX plugin, and real C2PA / Content Credentials integration.
