## Proposal to Reinstall the Cycles Index Canister
##### Proposer: DFINITY Foundation
##### Repository: http://github.com/dfinity/ic
##### Git Hash: `a98f434cc9ca5b2b0ec4b38e6a465363f17e17ff`
##### Compressed Wasm Hash: `3135319bae3acd71107e5c8a6de530ce02875d7d0abdfccd81e43e9e9c184d8d`
##### Argument Hex: `4449444c066e016b02fcb88b840302b0ced18403056c02f1f7fcf70603dcb79b830b046e686e786c02f1f7fcf70668dcb79b830b0401000101010a0000000002100002010100`
##### Target canister: `ul4oc-4iaaa-aaaaq-qaabq-cai`

---

## Motivation

Reinstall the Cycles Index Canister to reset its state now that it is under NNS control.
Another proposal is needed because the previous attempt to reinstall the ledger failed.

## Wasm Verification

Verify that the hash of the gzipped WASM matches the proposed hash.

```bash
git fetch
git checkout a98f434cc9ca5b2b0ec4b38e6a465363f17e17ff
./gitlab-ci/container/build-ic.sh -c
sha256sum artifacts/canisters/ic-icrc1-index-ng-u256.wasm.gz
```

## Argument Verification

```bash
git fetch
git checkout a98f434cc9ca5b2b0ec4b38e6a465363f17e17ff
read -r -d '' ARG <<EOF
(opt variant {
    Init=record {
        ledger_id=principal "um5iw-rqaaa-aaaaq-qaaba-cai";
    }
})
EOF
didc encode -f hex -d rs/rosetta-api/icrc1/index-ng/index-ng.did -t '(opt IndexArg)' "$ARG"
```


Upgrade Nns Canister: ul4oc-4iaaa-aaaaq-qaabq-cai to wasm with hash: 3135319bae3acd71107e5c8a6de530ce02875d7d0abdfccd81e43e9e9c184d8d
