The NNS Team submitted the following proposal. DFINITY plans to vote on it the following Monday.

https://dashboard.internetcomputer.org/proposal/135939

Additional Notes / Breaking Changes

This proposal installs the WASM previously propose in 135859 which successfully created a canister for Node Rewards, but failed the installation due to invalid initialization arguments. This uses the same canister and the same WASM but installs it with the correct arguments.

Proposals to be Submitted

# Install the Node-rewards Canister WASM at Commit 3a3cf55

__Proposer__: maximilian.summe at dfinity.org

__Source code__: [3a3cf55373bfe5843fac9fff6657127ae11b5dd8][new-commit]

[new-commit]: https://github.com/dfinity/ic/tree/3a3cf55373bfe5843fac9fff6657127ae11b5dd8

## Features & Fixes

* Install the canister wasm as approved in proposal [135859](https://dashboard.internetcomputer.org/proposal/135859)
  which failed due to invalid initialization arguments. This proposal will install the previously-approved code into the
  canister, as the canister was successfully created by the previous proposal.

## 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/3a3cf55373bfe5843fac9fff6657127ae11b5dd8/rs/nervous_system/docs/proposal_verification.md

### WASM Verification

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

[prereqs]: https://github.com/dfinity/ic/tree/3a3cf55373bfe5843fac9fff6657127ae11b5dd8/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 3a3cf55373bfe5843fac9fff6657127ae11b5dd8

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

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

This should match `wasm_module_hash` field of this proposal.

### Init Arguments Verification

[`didc`][latest-didc] is required.

[latest-didc]: https://github.com/dfinity/candid/releases/latest

```
didc encode '(record {})' | xxd -r -p | sha256sum

```

This should match the `arg_hash` field of this proposal.

Proposal #135939 for Node Rewards Canister — Zack | CodeGov

Vote: Adopted

Reason: The build is reproducible and the wasm hash as well the arguments hash is a match.
This follows the previous proposal 135859 that failed to execute due to invalid initialization arguments.
The canister id sgymv-uiaaa-aaaaa-aaaia-cai doesn’t have the expected name:"node_rewards" since the execution failed, and the install mode is install.
