# IC-OS Verification

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

```
# From https://github.com/dfinity/ic#building-the-code
# This process requires Mac/Linux/WSL2, Git and Podman on your machine.
git clone https://github.com/dfinity/ic
cd ic
git fetch origin
git checkout e4843a130730f515cf342d6b3ffa7191529a9df0
if ./gitlab-ci/container/build-ic.sh -i ; then
    wget -c https://download.dfinity.systems/ic/e4843a130730f515cf342d6b3ffa7191529a9df0/guest-os/update-img/update-img.tar.gz
    shasum -a 256 artifacts/icos/update-img.tar.gz update-img.tar.gz
else
    echo "IC-OS build failed. Verification unsuccessful." >&2
fi
```

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.
