## Verification

See the general instructions on [how to verify] proposals like this. A "quick
start" guide is provided here.

[how to verify]: https://github.com/dfinity/ic/tree/8ac2131be1a86e1267e7774b0c94085fc107bad3/rs/nervous_system/docs/proposal_verification.md


### WASM Verification

See ["Building the code"][prereqs] for prerequisites.

[prereqs]: https://github.com/dfinity/ic/tree/8ac2131be1a86e1267e7774b0c94085fc107bad3/README.adoc#building-the-code

```
# 1. Get a copy of the code.
git clone git@github.com:dfinity/ic.git
cd ic
# Or, if you already have a copy of the ic repo,
git fetch
git checkout 8ac2131be1a86e1267e7774b0c94085fc107bad3

# 2. Build canisters.
./ci/container/build-ic.sh -c

# 3. Fingerprint the result.
sha256sum ./artifacts/canisters/governance-canister.wasm.gz
```

This should match `wasm_module_hash` field of this proposal.
