# The Blind Machine

The Blind Machine is a platform for governed, content-addressed computation on
encrypted data. Raw, encoded, and private data stay on the user's machine. Only
encrypted contributions are uploaded for computation.

## Start with the CLI

```sh
uv tool install blindmachine
blind doctor
```

The `blind` CLI is the complete product surface. The website is a read-only
view of projects, jobs, billing, results, public application bundles, and
verification evidence.

## Core workflow

1. Create a governed project with a pinned application digest.
2. Generate encryption context locally.
3. Invite contributors and encrypt their data locally.
4. Freeze the cohort before computation.
5. Run the signed application over ciphertext.
6. Decrypt locally and verify the certificate offline.

Private keys, secret encryption contexts, raw data, and encoded data must never
be uploaded or pasted into an agent prompt. Project mutations can freeze a
cohort, consume credits, or dispatch computation; inspect the relevant API
operation before calling it.

## Public applications

- [Allele Frequency Count](https://blindmachine.org/applications/allele_frequency_count) — Exact aggregate allele counts over a sealed cohort (additive BFV, flagship).
- [Allele Frequency with Variance](https://blindmachine.org/applications/allele_frequency_with_variance) — Allele counts plus server-derived variance (multiplicative BFV, depth 1).
- [Carrier Count](https://blindmachine.org/applications/carrier_count) — Per-variant carrier counts over a sealed cohort (additive BFV).
- [Cohort Histogram](https://blindmachine.org/applications/cohort_histogram) — Bucketed one-hot counts over any cohort (additive BFV, generic).
- [Genotype-Phenotype Covariance](https://blindmachine.org/applications/genotype_phenotype_covariance) — Encrypted x encrypted covariance (multiplicative BFV, depth 1).
- [Polygenic Score Aggregate](https://blindmachine.org/applications/polygenic_score_aggregate) — Public-weighted score aggregate (additive BFV, plaintext-scalar multiply).
