Issue being fixed or feature implemented

A user on a pruned Dash Core node ran gobject prepare, which burned the 1 DASH proposal fee, and gobject submit then failed with only Invalid proposal collateral. gobject check had returned OK. The only advice available was to turn pruning off, enable -txindex and resync the whole chain.

The causes:

• Proposal collateral is looked up through -txindex.
• -prune soft-disables both -txindex and governance (-disablegovernance=1), so a pruned node can't check, relay or submit proposals at all.
• gobject prepare didn't check any of that before burning the fee.
• IsValidLocally replaced the collateral error detail with Invalid proposal collateral.

Pruned nodes also skip full superblock validation (they only check the maximum bounds) because they have no governance.

This PR makes governance work on pruned nodes. For nodes that still can't do it, gobject prepare/submit now fail before anything is burned.

What was done?

A prerequisite fix, in its own commit (fix(net): avoid unsigned wrap when compressing header timestamps)

• CompressibleBlockHeader::Compress subtracted timestamps as uint32_t, which wraps when a block is timestamped before its parent. The encoding sent was already correct, because such headers fall back to the full timestamp, but -fsanitize=integer builds abort while serving headers. feature_governance.py's pruned node re-downloads headers after -reindex, which hit this on linux64_asan-test. The commit only computes the offset when it cannot wrap, so the wire encoding is unchanged. It can be split into its own PR if preferred.

A test fix, in its own commit (test: wait for index rewinds after invalidateblock in feature_timestampindex)

• After invalidateblock, feature_timestampindex.py read the timestamp index before its BlockDisconnected callbacks had run. getblockhashes waits for an index that is behind the tip, but not for one that is ahead of it. develop's ASan job already failed this once and passed on retry. This PR's collateral index reads the disconnected blocks in the same validation queue, which made the ASan job lose the race every time (locally, 6 of 16 parallel runs failed). The test now calls syncwithvalidationinterfacequeue first, and 16 of 16 runs pass.

A prune-compatible governance collateral index

• governance::CollateralInfo summarises what the collateral check needs from a transaction: block hash, whether every output is P2PKH or unspendable, and the OP_RETURN <32-byte hash> burns. CGovernanceObject::IsCollateralValid now runs on that summary instead of on the raw transaction.
• GovCollateralIndex is a BaseIndex with AllowPrune(). It stores a CollateralInfo only for transactions that burn at least GOVERNANCE_PROPOSAL_FEE_TX, and keeps only their burns of at least that amount, so it stays small: every entry burns at least 1 DASH, so the number of entries is bounded by the DASH supply. It keeps working after the blocks are pruned. When blocks are disconnected in a reorg, their entries are removed again. It registers its prune lock in CustomInit, so startup pruning can't delete blocks a new index hasn't read yet. getindexinfo reports it as govcollateralindex.
• The index always runs. There is no option for it. Since backport: bitcoin#25193, #25862, #25943, #28123 and relevant fixes #7883, indexes also run during -reindex-chainstate: they wait until the chainstate has been rebuilt and then catch up, so this index does too.
• Governance looks collateral up only in this index and no longer uses -txindex at all. Until the index has synced, lookups fail with a clear error.
• The index lives in NodeContext (node.gov_collateral_index). Governance reaches it through governance::CollateralSource, a small interface in governance/collateral.h that CGovernanceManager receives in its constructor and IsValidLocally/IsCollateralValid take as a parameter. Governance code never includes the index, so the only new include cycle is index/base -> node/context -> index/govcollateralindex -> index/base, the same shape as the other Dash indexes.

Governance on pruned nodes

• -prune no longer soft-sets -disablegovernance, and Qt no longer forces it when pruning is enabled.
• The startup check that governance needs -txindex is gone. -reindex-chainstate with governance enabled is allowed, like -txindex with -reindex-chainstate since backport: bitcoin#25193, #25862, #25943, #28123 and relevant fixes #7883.
• A node that pruned blocks the index hasn't read can't build it. That covers a pruned node upgrading to this version. BaseIndex::Init would refuse to start such a node, so it now starts with governance off and a warning to restart once with -reindex.
• Governance P2P messages are ignored, and the governance sync stage waits without timing out, while the index is still catching up. Otherwise peers would be punished (Misbehaving(20)) for objects that only failed because the index lags.
• Governance announcements received meanwhile are held per peer instead of dropped. They are requested from the announcing peer once governance can process them, i.e. once both the index and the blockchain have synced. They are handed to the request tracker in the order they were announced, only as many as the peer's pending-announcement allowance has room for; the rest wait until earlier announcements have been requested. A peer never announces the same inv to us twice, and its later sync response skips what it already announced, so dropping them would lose those objects and votes on that connection until a reconnect. This uses a new NetHandler::DeferAnnouncement hook. Each peer can have as many announcements held as it may have pending in the request tracker (MAX_PEER_OBJECT_ANNOUNCEMENTS), and they are freed when the peer disconnects. A peer that announces more than that while governance is waiting is disconnected right away. The node can't have asked that peer for a governance sync yet, so a new connection to it still gets a full one.

Fail before burning the fee

• gobject prepare and gobject submit refuse on nodes that can't check or relay proposals, and say why and what to do. So do the Qt createProposal/submitProposal interfaces.
• IsValidLocally keeps the collateral detail: Invalid proposal collateral: Couldn't find opReturn … burning at least 1.00 in collateral tx ….
• gobject check's help says it only checks the proposal data.

Consensus note: pruned nodes with governance now validate superblock payments in full, like full nodes, instead of checking only the maximum bounds. This gives them the same exposure as full nodes: they reject a non-ChainLocked superblock that doesn't pay a trigger they consider funded.

Decided after review

1. The index always runs, and -govcollateralindex is gone.
2. Governance no longer uses -txindex.
3. The index lives in NodeContext instead of a global.
4. The pruned-node scenarios are part of feature_governance.py (one of its nodes is pruned) instead of a separate test. feature_governance_txindex_devnet.py is removed.
5. The index runs during -reindex-chainstate, like the other indexes since backport: bitcoin#25193, #25862, #25943, #28123 and relevant fixes #7883, and governance no longer refuses -reindex-chainstate.

Still open

1. Every node builds the index once, on the first start after upgrading, by reading every block. Masternodes and other -txindex nodes are included, since governance no longer uses -txindex. Until the index has synced, the node ignores governance messages and its governance sync waits, so mnsync doesn't finish. On those nodes that means:

   • masternodes don't create or vote on triggers;
   • superblocks are checked against the maximum bounds only.

   The mainnet build time hasn't been measured. If it is long, the options are: use -txindex as a temporary source until the index has synced (glue in init.cpp; governance code wouldn't change), or only hold back proposals instead of all governance messages while the index catches up.

2. Removing -disablegovernance altogether, so governance always runs and the flag only hides the UI, is left for a follow-up. It changes what every node downloads, stores and relays, and the functional tests rely on the flag.

3. The index stores only transactions burning ≥ GOVERNANCE_PROPOSAL_FEE_TX. If the proposal fee ever changes, the index needs a rebuild or a version bump.

4. No proof-import path is included, i.e. submitting a proposal with a merkle proof for collateral the node has pruned past.

5. Index size on mainnet hasn't been measured. It's bounded by the number of fee-burning transactions.

How Has This Been Tested?

On macOS arm64, with a debug build (--enable-debug --enable-werror, GUI included) on top of develop 23479b9. After the rebase onto develop 66c7308 (which includes #7883), it was rebuilt (--enable-debug, no GUI) and test_dash --run_test='governance_*', feature_governance.py, feature_reindex.py and feature_index_prune.py were run again and pass. With the old -reindex-chainstate gate put back in init.cpp, the new -reindex-chainstate step in feature_governance.py fails (govcollateralindex is missing from getindexinfo). After rebasing onto develop 35a115e, the branch was rebuilt and test_dash --run_test='governance_*', feature_governance.py, rpc_blockchain.py, feature_index_prune.py, feature_reindex.py, wallet_pruning.py and the other governance functional tests pass. rpc_blockchain.py no longer expects the pruned-node governance warning in the checks that came with bitcoin#27235, because pruned nodes now run governance. Commits are split so each one builds: the index, then governance on pruned nodes, then the early refusal.

• Unit tests: test_dash --run_test='governance_*' passes. That covers governance_collateral_tests, governance_inv_tests, governance_vote_processing_tests and the other governance suites.

  • governance_collateral_tests checks three things. Only exact OP_RETURN <32 bytes> scripts count as burns. The index records fee burns, skips smaller burns and coinbases, and indexes blocks both before and after it starts. Collateral checks give the "not running" and "not synced" errors.
  • governance_inv_tests checks that while the index is behind, an announced object is neither requested nor punished. Once the index has synced, the object is requested from the same peer without it announcing the object again, then rejected and punished. The test uses a stub CollateralSource. If the announcement is dropped instead of held, the request check fails.
  • governance_vote_processing_tests now uses the governance collateral index instead of -txindex.

• feature_governance.py: node 1 is now a pruned node (-prune=550 -fastprune) without -txindex. It takes part in every existing scenario, and the test checks that it:

  • receives proposals, votes and triggers;
  • prepares a proposal of its own;
  • reports why bad collateral is wrong;
  • rejects a superblock that keeps the budget for the miner (bad-cb-amount) and accepts the real one with full checks, not "max bounds only";
  • finds collateral after its block is pruned;
  • keeps objects across a restart;
  • starts with governance off and refuses prepare/submit early when its index is missing;
  • gets governance back after -reindex.

  Node 0, which is not pruned, is then restarted with -reindex-chainstate. The test checks that getindexinfo reports govcollateralindex as synced and that gobject submit still finds the proposal's collateral.

  Run 3 times one after the other, all passed. Twice it was also run as two parallel copies on a heavily loaded machine. One of those runs failed in have_trigger_for_height because three masternodes each created an identical-data trigger for the same height. That is the known flake in tests: feature_governance.py is flakey #6705 and test: feature_governance.py intermittent vote/superblock assertions #7328, and it is not specific to the pruned node.

• Other functional tests, all passing: feature_governance_cl.py, feature_governance_objects.py, rpc_misc.py, feature_index_prune.py, feature_reindex.py, wallet_pruning.py, rpc_rawtransaction.py, rpc_blockchain.py, rpc_getblockfrompeer.py, wallet_crosschain.py, p2p_dos_header_tree.py, p2p_node_network_limited.py and feature_remove_pruned_files_on_startup.py.

• Lints: lint-circular-dependencies (the only new cycle is index/base -> node/context -> index/govcollateralindex -> index/base), lint-files, lint-format-strings, lint-whitespace and lint-includes pass. lint-python reports only an unused import in feature_governance.py that is already on develop. clang-format 18 is clean on the new files.

• Not run:

  • feature_pruning.py. It now runs its pruned nodes with governance on. It failed on develop before this PR for an unrelated reason (evodb snapshot missing).
  • The Qt change (Options → prune no longer forces -disablegovernance) was not exercised in a GUI.

• Reviewer pass: an independent review found no lifetime, ordering or init problems. Its main remaining concern is the open item about the first index build after upgrading.

Breaking Changes

• Pruned nodes and nodes started with -txindex=0 now run governance. Every node builds the governance collateral index once after upgrading. A node that pruned before upgrading starts with governance off, a warning, and the advice to -reindex once.
• Dash-Qt nodes that turned pruning on in the options have disablegovernance=1 saved in settings.json, and governance stays off on them until that setting is removed.
• -prune together with -disablegovernance=0 is no longer an error.
• getindexinfo always includes govcollateralindex while the index runs, so it is no longer empty without optional indexes.
• gobject prepare/submit errors and the collateral error strings changed.

✅ Final review complete — no blockers (commit f2ade38) · triage: normal

[knst]

concept ACK, I like idea to run governance on nodes without txindex.

First part of comments are relevant even PR is draft, consider them.

Firstly [a]: governance index should never be more than some certain amount, because it's always burn at least 1 dash.
So, in the worst possible scenario it would be only 18M of items [if all dashes are burned to proposals]

consider having proposal index always by default, not only when it's enabled by command line option.
The overhead is tiny and total amount of extra data on disk is tiny fraction even for pruned nodes.
So, it will remove command line option -govcollateralindex, related logic and it will simplify user-faced interface, less things to have "just work as it is" and "less things to configure".

Firstly [b]: so far as governance doesn't require txindex at all, consider removing command line -disablegovernance completely; enabling / disabling governance may switch on / off tabs in UI only then.

Secondly, consider migrate-out from txindex in governance completely.
It would simplify implementation, it will make less cognitive load to users; and governance could be enabled on pruned, on non-pruned nodes, with txindex, without txindex with the same behaviour because non of that relevant.

Thirdly, instead making brand new test/functional/feature_governance_pruned.py better add option --prune for one of the nodes that participate in feature_governance.py, it will ensure that all scenarious that should be covered will be covered once and no need to sync feature_governance.py and feature_governance_pruned.py when feature_governance.py will get a brand-new scenario or corner case to test.

---

Second part of comments [below] are probably irrelevant, because it's still draft and they are about details of implementation rather about concept and functionality, but read them at least.

1. The script test/functional/feature_pruning.py could remove -disablegovernance= as it is not blocker anymore.

2. completely remove test/functional/feature_governance_txindex_devnet.py as irrelevant, especially if enforce governance index to always exist.

3. new circular dependencies:

    "active/context -> governance/governance -> governance/object -> index/govcollateralindex -> index/base -> node/context -> active/context",
    "dsnotificationinterface -> governance/governance -> governance/object -> index/govcollateralindex -> index/base -> node/context -> dsnotificationinterface",
    "governance/object -> index/govcollateralindex -> index/base -> node/context -> governance/superblock -> governance/object",
    "governance/governance -> governance/object -> index/govcollateralindex -> index/base -> node/context -> governance/governance",

that's a bit too many new circular dependencies are added. I expect to see only "index/base -> node/context -> index/govcollateralindex -> index/base", same as for other indexes.

Thanks for the review. I rebased onto develop 23479b9 (old head 08456cb, new head 083abff) and reworked the PR along your comments. Point by point:

[a] The index is always on, and -govcollateralindex is gone. Done. Every node runs the index. The only exception is -reindex-chainstate, which no index runs during. Outside regtest, that combination with governance on is still refused, as on develop. The option, its soft-set and its -reindex-chainstate error are removed. A node that pruned before it had the index can't build it from genesis, so it starts with governance off and a warning to -reindex once.

[b] Removing -disablegovernance completely. Not in this PR; I've listed it as a follow-up in the description. Removing it changes what every node downloads, stores and relays, not only the UI, and many functional tests start nodes with it. With the index always on, nothing here depends on the flag anymore, so the follow-up is mostly about the UI and the tests. Happy to do it next if you agree.

Secondly: migrate governance off txindex completely. Done. Collateral is looked up only in the governance collateral index; g_txindex is no longer used anywhere in governance. The open decision "txindex takes precedence" is gone with it.

One consequence, also listed under "Still open" in the description: every node, masternodes included, builds the index once on its first start after upgrading. Until it has synced, the node ignores governance messages and its governance sync waits. If the mainnet build turns out to be long, we could use txindex as a temporary source in init.cpp until the index has synced, or hold back only proposals instead of all governance messages.

Thirdly: fold the test into feature_governance.py. Done. feature_governance_pruned.py is removed. Node 1 of feature_governance.py is now a pruned node without txindex. It takes part in all existing scenarios, and the pruned-specific checks are added there: full superblock validation, collateral found after its block is pruned, refusing prepare/submit early, and recovery with -reindex.

1. feature_pruning.py: all -disablegovernance uses are removed. The pruned nodes run governance now.

2. feature_governance_txindex_devnet.py: removed.

3. Circular dependencies: the index now lives in NodeContext (node.gov_collateral_index) instead of a global. Governance reaches it through a small governance::CollateralSource interface in governance/collateral.h, so governance code never includes the index. The four extra cycles are gone; the allowlist now has only index/base -> node/context -> index/govcollateralindex -> index/base, like the other Dash indexes.

The PR stays a draft while the open items in the description are discussed.

Walkthrough

The change adds a LevelDB governance collateral index and uses it instead of -txindex for governance collateral checks. Startup checks whether the index can sync from available block data. Governance validation, network processing, synchronization, RPCs, and node interfaces now use the index. Pruning no longer automatically disables governance. Tests cover index behavior, pruned-node governance, index reporting, and related startup rules. Block-header timestamp compression also changes its handling of timestamps earlier than the parent.

Block fee creation until the collateral index is synced

On the first startup after upgrading an existing node, gov_collateral_index is non-null while its initial full-chain scan can still be unsynced, so this existence-only guard lets gobject prepare create and broadcast the irreversible fee. BlockUntilCollateralIndexSynced() then returns false immediately for that initial catch-up (its result is ignored), and the subsequent gobject submit fails because FindCollateral refuses an unsynced source; the analogous pointer-only guard in interfaces.cpp::createProposal leaves the Qt flow exposed too. Include the source's synced/behind state in both early gates so this upgrade path also fails before burning the fee.

AGENTS.md reference: AGENTS.md:L234-L241

Useful? React with 👍 / 👎.

[PastaPastaPasta]

Fixed in bdc568a, folded into "fix(governance): refuse proposals early on nodes that can't check them". EnsureCanSubmitProposals (used by gobject prepare and gobject submit) and createProposal in interfaces.cpp now also require gov_collateral_index->BlockUntilSyncedToCurrentChain(). That call returns false right away while the index's initial sync is still running, so during the first catch-up after an upgrade, gobject prepare and the Qt proposal flow refuse before the fee is created, with "still building its governance collateral index (see getindexinfo) … try again once the index has synced". Once the index is synced, the same call waits for pending notifications, as BlockUntilCollateralIndexSynced already did.

I didn't add a test: on regtest the index catches up almost immediately after startup, so the unsynced window can't be hit reliably. feature_governance.py --descriptors passes with the change.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Check index synchronization before submitting a proposal.

When context().gov_collateral_index exists but is still building, submitProposal passes it to CGovernanceObject::IsValidLocally without calling BlockUntilSyncedToCurrentChain(). The collateral check can therefore reject valid collateral that has not been indexed yet.

submitProposal is independently reachable from the proposal-resume flow, even though createProposal waits for synchronization. Add the same synchronization check before collateral validation. This is a functional rejection of a valid submission, not persisted-data or API integration corruption.

Re CodeRabbit's outside-diff Major on interfaces.cpp:532-535 (submitProposal doesn't wait for the index): fixed in ac049c9, folded into "fix(governance): refuse proposals early on nodes that can't check them". submitProposal now calls gov_collateral_index->BlockUntilSyncedToCurrentChain() before validating, as createProposal and the gobject prepare/submit RPCs already do. While the index's initial sync is running, the resume flow now returns "still building its governance collateral index" instead of rejecting valid collateral.

Final validation — Phase 1 + Phase 2

Verified both reviewer findings against head ac049c9; one targeted test-coverage suggestion remains, with no blocking issues. The null-source report describes pre-existing regtest behavior rather than a regression introduced by this PR. Validation was static only: the supplied CI snapshot shows successful source builds and lint still in progress.

In `test/functional/feature_governance.py`:
- [SUGGESTION] test/functional/feature_governance.py:470: Revalidate pruned collateral after reopening the index
  This assertion verifies that the proposal survives in governance.dat, but listing an existing proposal does not validate its collateral. It therefore does not check that the reopened index can deserialize and use its persisted collateral summary, which is essential once the original block has been pruned. Submit the same parameters again here: gobject submit validates collateral before reaching duplicate-object handling, so this directly exercises the persisted index without requiring another scenario.

Out-of-scope follow-up suggestions (1)

These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.

• IsCollateralSourceBehind misses null collateral source — The identified peer-penalty behavior is pre-existing, not newly exposed by this PR. At base 23479b9, -reindex-chainstate requires -txindex=0, regtest bypasses the governance/txindex requirement, and IsCollateralValid fails whenever g_txindex is null; ProcessObject then returns false and NetGovernance applies the same 20-point penalty. At this head, init.cpp disables governance for the other unavailable-source case (blocks already pruned), and rejects governance with -reindex-chainstate outside regtest. IsCollateralSourceBehind specifically reports a source that is catching up, as documented in governance.h; treating the intentionally absent regtest source as behind would additionally hold governance sync indefinitely because that source cannot become available during the process lifetime. This does not justify expanding the PR to change the existing regtest exception.
  • Follow-up: Consider creating a separate issue or author/maintainer-requested PR for this.

Applied in 2533efb (folded into "feat(governance): run governance on pruned nodes"). After the restart, the test now waits for govcollateralindex to report synced, then resubmits the same parameters and checks it gets the same hash back. The wait is needed: since the earlier fix, gobject submit refuses while the index is still catching up. feature_governance.py --descriptors passes.

Resolved (re-reviewed at 2533efbc): Thanks—the restart scenario now waits for govcollateralindex to report synced and resubmits the same parameters, checking the original hash. I verified that gobject submit validates collateral before duplicate-object handling, so this exercises the reopened index's persisted summary after the original block has been pruned.

Account for queued callbacks before reporting collateral synced

When a proposal is relayed immediately after its fee block is connected, the index's BlockConnected notification can still be queued even though BaseIndex has latched summary.synced to true from an earlier tip. This predicate therefore lets NetGovernance::ProcessMessage validate the object, FindCollateral misses the not-yet-indexed transaction, and ProcessObject treats an otherwise valid proposal as permanently invalid and scores the announcing peer 20. The collateral-source readiness check needs to account for the index's current best block/validation queue, not only whether its initial catch-up completed once.

This race isn't new with this PR. On develop, IsCollateralValid calls g_txindex->FindTx directly (src/governance/object.cpp, around line 800), and txindex is updated by the same queued BlockConnected callback with no BlockUntilSyncedToCurrentChain() beforehand. So a proposal relayed while its fee block's notification is still queued is already rejected there, and the peer is scored 20 by the same ProcessObject path. The new index keeps that behaviour and doesn't widen the window.

The window is a single block: an honest node relays at GOVERNANCE_MIN_RELAY_FEE_CONFIRMATIONS and later confirmations. The clean fix is to treat "not found while the source's best block isn't the active tip" as fMissingConfirmations, so the object is postponed and rechecked by CheckPostponedObjects instead of being rejected. That applies to txindex and this index alike, so I'd rather do it as a separate small fix than grow this PR. Leaving it as is here.

Re-review — Final validation — Phase 1 + Phase 2

Independently reviewed the complete diff at 2533efb, including collateral validation, index persistence and lifecycle, pruning safeguards, synchronization gates, proposal refusal paths, and test adaptations; no actionable in-scope issues were found. The prior persisted-collateral coverage finding is fixed. Validation was static only: the supplied exact-head CI snapshot still had build/cache checks queued and lint running, so completed build and test validation is not established.

Re-review — Final validation — Phase 1 + Phase 2

The PR correctly implements the pruned-node governance flow, collateral indexing, deferred announcements, and early proposal refusal. The checked-in dashd and dash-qt manual pages still document pruning as incompatible with -disablegovernance=false, contradicting the updated runtime help and release notes; the remaining ASan, TSan, and multiprocess checks are still in progress while completed build, test, and lint checks pass.

🟡 Suggestion: Update generated prune option documentation
doc/man/dashd.1:152

The checked-in generated dashd.1 and dash-qt.1 manual pages still state that pruning is incompatible with -disablegovernance=false. This PR removes that restriction in src/init.cpp and explicitly enables governance on pruned nodes, so users consulting the installed manuals receive advice that contradicts the runtime behavior and release notes. Regenerate or update both manual pages to match the current -prune help text.

On the suggestion in review 5693329682 (update the -prune text in doc/man/dashd.1 and doc/man/dash-qt.1): I'm leaving those files alone. Both are generated by help2man from the binaries' --help output. They start with DO NOT MODIFY THIS FILE!, and they're regenerated in each release-prep commit (see the "Update manpages" step in doc/release-process.md and contrib/devtools/gen-manpages.py). They still describe v23.1.8, so they already differ from develop's help text in other places. This PR updates the -prune help text in src/init.cpp, and the man pages pick that up the next time they're regenerated for a release.
