# IC-OS Verification

To build and verify the IC-OS disk image, run:

```
# From https://github.com/dfinity/ic#verifying-releases
sudo apt-get install -y curl && curl --proto '=https' --tlsv1.2 -sSLO https://raw.githubusercontent.com/dfinity/ic/2c4566b7b7af453167785504ba3c563e09f38504/gitlab-ci/tools/repro-check.sh && chmod +x repro-check.sh && ./repro-check.sh -c 2c4566b7b7af453167785504ba3c563e09f38504
```

The two SHA256 sums printed above from a) the downloaded CDN image and b) the locally built image, must be identical, and must match the SHA256 from the payload of the NNS proposal.
