## Wasm Verification

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

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

```
# 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 0d96610b842ca721e50169c65bdfbc5d6d3d8b67

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

# 3. Fingerprint the result.
sha256sum ./artifacts/canisters/ic-icrc1-archive.wasm.gz
```

This should match `wasm` field of this proposal.
