Proposal 136071 – LaCosta | CodeGov

Vote: ADOPT

Governance Canister

image
Reason:
Build successful and hashes match, commits look great and match the description. Found no issues.

[21a34cea35]: Disables the Neuron Fund according to adopted proposal 135970. Includes a check in validate_create_service_nervous_system to verify if are_nf_fund_proposals_disabled is true along with neurons_fund_participation being enabled, throwing an error in that case.

[98e8d97621]: Removes the USE_STABLE_MEMORY_FOLLOWING_INDEX feature flag and test functions temporarily_enable/disable_stable_memory_following_index. Init argument topic_followee_index, Followers and FollowersMap following the transition to stable storage.

[e325bb0616]: Adds node-rewards to the list of canisters to be included in the Bazel build. Assigns the canister ID sgymv-uiaaa-aaaaa-aaaia-cai on both the local and mainnet. Updates ALL_NNS_CANISTER_IDS in order to include this canister along with ledgers archives and PROTOCOL_CANISTER_IDS to be used as ProtocolCanisterManagement proposals.

Proposal 136072 – LaCosta | CodeGov

Vote: ADOPT

Governance Canister

[f6425d47af]: Node Provider Reward calculation documentation.

Updates ALL_NNS_CANISTER_IDS in order to include this canister along with ledgers archives and PROTOCOL_CANISTER_IDS to be used as ProtocolCanisterManagement proposals.

[2fe8aefafc]: Makes the NodeRewardsCanister capable of syncing data from the IC Registry Canister at regular intervals. Schedules a 1 hour interval REGISTRY_SYNC_INTERVAL_SECONDS to sync the data using StableCanisterRegistryClient. CanisterRegistryClient trait now has two functions get_latest_version and sync_registry_stored to call the Registry implemented on StableCanisterRegistryClient that uses StableMemory to store a copy of the Register data.

21a34cea35 feat(nns): Disables the Neuron Fund for new SNS, adds a function to check whether NNS (Neurons’ Fund) proposals are currently disabled.
98e8d97621 refactor(nns): Removes unused topic_followee_index and it’s reserved id 22 from heap while removing also the USE_STABLE_MEMORY_FOLLOWING_INDEX feature flag that is now set to true since proposal 135063
e325bb0616 chore(nns): With the following proposal that enables node-rewards to sync changes from the Registry canister is now added and supported by the release scripts with id sgymv-uiaaa-aaaaa-aaaia-cai.

Proposal #136072 for Node-rewards-canister — Zack | CodeGov

Vote: Adopted

Reason: The build is reproducible and the wasm hash is a match.

f6425d47af docs(node-rewards): Node Provider Reward Calculations added to docs. Well worth a read, for anyone who did not do so yet, and is screaming left and right, specially the The reward calculation implementation part.
e325bb0616 chore(nns): same as in the Governance canister.
2fe8aefafc feat(node-reward): Allows the Node Rewards canister to sync from the Registry canister at different intervals, currently set to 1 hour in post upgrade.
The 2 asynchronous methods get_latest_version and registry_changes_since are used to call the Registry.
The CanisterRegistryClient get’s a cleanup.All is done in preparation for the upcoming dynamic node provider rewards.

Adopt proposal 136071

Proposal

  • Canister id rrkah-fqaaa-aaaaa-aaaaq-cai is indeed the governance canister.
  • The upgrade args correspond to the empty args.
  • The install mode is indeed upgrade.
  • The wasm hash is reproducible.

image

  • Neuron fund is now disabled following abuse from a 3 SNS projects.

Adopt proposal 136072

Proposal

  • Canister id sgymv-uiaaa-aaaaa-aaaia-cai is indeed the Node-rewards Canister.
  • The upgrade args correspond to the empty args.
  • The install mode is indeed upgrade.
  • The wasm hash is reproducible.

image

Introduced flexibility for the Node Rewards canister to sync with the Registry canister at adjustable intervals (currently set to 1 hour in post-upgrade hooks). Leveraged two async methods—get_latest_version and registry_changes_since—to query the Registry efficiently. Updated the CanisterRegistryClient with a cleanup pass. This lays the groundwork for the upcoming dynamic node provider reward system.

Proposal 136071 - Zane | CodeGov

Vote: ADOPT
Reason: Build completes successfully, both hashes and reviewed commits match their descriptions.

136071

21a34cea35 Added DISABLE_NF_FUND_PROPOSALS flag to governance canister global state and use it to gate neuron fund access in validate_create_service_nervous_system. If a new SNS is being created and it defines a neuron fund participation while the NF is disabled an InvalidProposal error is returned. Added some helper methods to toggle the NF in tests.

98e8d97621 Deleted USE_STABLE_MEMORY_FOLLOWING_INDEX feature flag alongside all the code associated with it. Since the index is persisted in stable memory, all references to the heap version, i.e topic_followee_index, alongside the rust/proto definitions for its type have been cleaned up.

e325bb0616 Specified node rewards canister as one of NNS candidates in run_determine_targets release scripts, added local and mainnet id for node rewards canister to the nns canister ids. New constants have been defined in rs/nns/constants/src/lib.rs for the canister id/index of both reward canister and the third ICP ledger archive, furthermore ALL_NNS_CANISTER_IDS array now specifies ids for all icp ledger archives, ledger index, subnet rental and node rewards canisters.
create_canister_id_at_position has been refactored into ensure_canister_id_exists_at_position method, the new implementation first checks whether the speciifed id already exists before proceeding to create it. Added setup_nns_node_rewards_with_correct_canister_id to allocate the expected id specified in the NNS constants and install the relative wasm.

Proposal 136072 - Zane | CodeGov

Vote: ADOPT
Reason: Build completes successfully, both hashes and reviewed commits match their descriptions.

136072

f6425d47af Added documentation for node provider reward calculations.

e325bb0616 Duplicate from 136071.

2fe8aefafc Defined Registry trait and implemented it for both RegistryCanister and FakeRegistry structs, making it possible for other canister to more easily interact with the registry or a mocked client for testing purposes. Also defined a trait named CanisterRegistryClient which defines an interface to sync to and read from a local cache of the registry and implemented it for StableCanisterRegistryClient which is used to persist the cache in stable memory. The syncing process is scheduled with a timer and happens every hour.
