fix(drive-abci)!: follow operator payout changes and repair operator keys at protocol 15 - #5775
Platform keeps its own copy of Dash Core's masternode list. It builds the copy from Core's full list at init chain, then applies Core's protx listdiff diffs block by block. Each masternode's operator identity gets a TRANSFER key (ECDSA_HASH160 of the operator payout address), and that key signs credit withdrawals from the identity. Up to protocol version 14 the payout handling was broken in two ways:
The stored payout never changed after Platform first saw a masternode.
A ProRegTx cannot carry an operator payout; only a later ProUpServTx sets one. So nearly every masternode registered after Platform genesis with an operator reward has an operator identity without a TRANSFER key, and nobody can withdraw credits sent to it.
An operator who changed the payout in Core kept the old address as the Platform key.
A new operator inherited the previous operator's payout key. Core clears the payout on every operator key change (ProUpRegTx with a new key, ProUpRevTx). update_operator_identity v0 still gave the new operator identity a TRANSFER key from an existing key or from the stored payout, both of which belong to the earlier operator.
On mainnet, from the repo fixture at Platform genesis and today's public masternodelist:
At genesis: 3,728 masternodes, 227 of them with an operator reward and 225 with an operator payout.
Today: 3,001 masternodes, 1,125 registered after genesis.
About 70 operator identities are probably missing their key (the genesis rate of ~6% applied to those 1,125).
31 masternodes from the genesis era have changed operator key since; one of them has an operator reward.
No user has lost anything yet. An operator identity receives credits only through the owner's rewardShare documents, and the public explorer shows 0 such documents on mainnet and 0 on testnet. The wrong keys guard empty balances today.
Both items change identity keys in GroveDB, so the fix starts at protocol version 15 (unreleased: testnet runs 14, mainnet 13). Protocol versions 1 to 14 replay exactly as before.
What was done?
Everything below is selected only by protocol version 15's table (DRIVE_ABCI_METHOD_VERSIONS_V11, amended in place).
update_masternode_list 2 (update_state_masternode_list_v2, a copy of v1):
A diff's operator payouts are kept.
For an operator key change that Core prints without a payout, the payout is read from Core: get_masternode_state (getblockhash(c), then protx info <proTxHash> <blockHash>) at the block's chain-locked height. Only the answer's state is decoded. rust-dashcore's typed ProTxInfo reads operatorReward as an integer, while Core prints a decimal (13.37 and 2.5 on mainnet), and its metaInfo holds node-local numbers. The hash is sent in Core's form (to_string; to_hex is byte-reversed). drive-abci refuses to start when Core refuses protx info (HTTP 403), like its getspecialtxes startup check. Core empties the payout on every key change and prints nothing for the clear. It also prints a payout only when it differs between the diff's two heights, so an entry without one cannot tell "cleared" from "set again to the same payout" (rotate and restore inside one c range). Only such entries trigger the call: about one per operator key change, and mainnet has had 31 since Platform's genesis. A Core error fails the block. A payout printed in the diff is used as is.
A key that Core only re-encoded is dropped before the clear is inferred, as fix(drive-abci)!: keep the operator identity when Core re-encodes the same operator key #5461 does, so a re-encode is never read as a key change. Whether V24 is active now comes from the Core fork record (fetch_core_fork_activation_height) instead of a Core call. The list update runs inside update_core_info v1, after the record step at the same c, and only in blocks that move c, so the record gives the same answer Core would.
Diffs apply with DMNState::apply_diff, which keeps a revived height the diff does not print.
update_operator_identity 1:
Given a payout, it reconciles every TRANSFER key of the identity it updates:
it reuses the key holding the payout (an enabled one first) or re-enables it;
it adds the key if there is none;
it disables every other enabled TRANSFER key.
There are no fallbacks to an earlier operator's key, and a key change without a payout means no payout.
It is idempotent: a payout Core re-sends cannot add a duplicate key, which with v0 fails IdentityKeyAlreadyExists on every node and halts the chain. Step 5 of the spec's earlier draft, a filter for re-sent payouts, is therefore not needed and was dropped. Keeping it would also stop a re-sent payout from healing an identity's keys.
A switch back to a retired identity reconciles its TRANSFER keys, which disables a key left by an earlier operator.
The identity a masternode leaves keeps its TRANSFER keys, so its operator can still withdraw what was sent to it.
Each step touches only its own kind of key: the BLS operator key, the platform node id key, the TRANSFER keys. So one key is never disabled or re-enabled twice in one update. Without this, an operator could set a payout equal to its platform node id and fail the block on every node; the code review found that chain halt.
A key whose public-key hash another key of the identity already has is added like any other. Payouts and node ids are any 20 bytes Core accepts, so an identity can need two keys of different kinds with one hash. Drive used to fail such an add with IdentityKeyAlreadyExists.
Drive add_new_keys_to_masternode_identity 1 (new slot: 0 in every shipped DRIVE_VERSION, 1 in DRIVE_VERSION_V10, which only PV15 selects): a masternode key whose hash the identity already holds a non-unique key-hash reference for, or that an earlier key of the same call has, is added without a second reference. Each key keeps its own id and purpose. User identity updates keep add_new_keys_to_identity and are unaffected.
Drive apply_drive_operations 2 (PV15-only, amended in place): after a batch is lowered, it keeps the first of the identical inserts that create a hash's tree under the non-unique key hashes tree. Each identity operation is lowered against stored state, so several identities adding a key of one new hash in one batch each queue that tree; masternodes whose operators share a payout address do this in the reconciliation. A batch checked for consistency (batching_consistency_verification) refused the repeats. The unchecked default kept the last of the identical inserts, so default nodes write the same state either way.
One-time reconciliation in the first block of protocol version 15 (transition_to_version_15 → reconcile_operator_payouts_with_core):
It reads Core's full masternode list (protx listdiff 1 c_prev) at the last committed chain-locked core height c_prev, the height Platform's list is at when the upgrade hook runs. The block's own diff c_prev → c is applied afterwards, under the new rules.
Where a stored payout differs from Core's, it stores Core's. Every masternode's current operator identity goes through update_operator_identity 1 with Core's payout. That reconciles all of its TRANSFER keys and changes nothing where they already match. The stored payout alone does not tell which identities need it: up to PV14 a platform node id matched keys by data alone, so an evonode whose node id once had its payout's bytes can have its payout key disabled while the stored payout and Core's agree.
There is no GroveDB record. The first block of a protocol version is unique by construction, and a jump from 13 or 14 straight to 16 or later passes through the same ladder step.
A Core error fails the block. So does a Core list whose masternodes are not Platform's; the error names the first 10 mismatched masternodes on each side. A malformed answer (removals, updates, a masternode listed twice) also fails the block.
Why read Core in the upgrade block here, when core-fork-activations.md avoids it for the fork probe:
A one-time reconciliation needs Core's full list. Nothing in Platform's state can replace it.
c_prev is chain locked and an earlier block already read Core at it, so every validator's Core holds that block and reports the same list.
The cost is accepted once: a node whose Core cannot answer cannot execute that one block, whatever its own c.
The book's paragraph now says this.
Why c_prev and not the proposal's c: the hook runs before update_core_info applies this block's diff. Reconciling the c_prev list against Core's list at c would compare two different lists. For a masternode whose operator key changes inside c_prev..c, it would also give the old operator's retired identity the new operator's payout key, which the following diff cannot undo.
Budget: infraclaw measured protx listdiff 1 <tip> on a mainnet Core (Dash Core 23.1.3, 3,001 masternodes) at 4.45 s cold and 0.80 s warm, for 3.3 MB of JSON. A one-block diff takes 0.07 s. Against the limits:
Tenderdash's genesis propose timeout is 50 s (testnet 30 s), so the upgrade block fits with room to spare.
drive-abci's proposer tx-processing limit (5,000 ms on mainnet and testnet) is measured from the start of prepare_proposal. With a cold Core, the proposer leaves the upgrade block's state transitions unexecuted (ProposerRanOutOfTime), and they go into the next block. Nothing fails.
Identity work: one key read per masternode (about 3,000 on mainnet), plus key writes for the few hundred mismatches at most. Estimated at 1-3 s; not measured on mainnet hardware. Together with the Core read, the upgrade block likely carries no state transitions on the proposer (above), which is harmless.
Plumbing and tests:
perform_events_on_first_block_of_protocol_change (dispatcher and all three generations) gains block_platform_state: &mut PlatformState and a CoreRPCLike bound. Only transition_to_version_15 uses them.
Tests that run the protocol 15 upgrade on a platform without masternodes get a mock Core that lists none (TempPlatform::with_no_core_masternodes, full lists only).
The strategy tests' Core mock now answers a full-list request at a later height with the strategy's list at that height, instead of the genesis list.
Book: core-fork-activations.md Consumers (the list update reads the record from generation 2 on) and the upgrade-window paragraph; component-pipeline.md "Syncing with Dash Core" (the upgrade block's Core read).
dashmate: Core refuses a method to drive's consensus RPC user until its whitelist names it. So protxinfo joins the default drive_consensus whitelist, and a 5.1.0-beta.1 migration adds it to existing configs. A user without a whitelist already may call every method. The migration has a unit test.

update_masternode_list v0/v1, update_state_masternode_list v0/v1 and update_operator_identity v0 are byte-identical. Their tests are now pinned to protocol version 14, as the conventions ask when a new generation lands.
How Has This Been Tested?
Red → green (each fix's tests run first against the code without it):
operator_payout_tests, against the unfixed tree: all 5 fail. The payout key is not added, the new operator inherits P0, a retired identity keeps P0, and the revived height is cleared.
With list v2 but update_operator_identity still 0, the re-sent payout test fails with IdentityKeyAlreadyExists: the chain halt.
With update_operator_identity 1, all pass.
With the reconciliation call removed from transition_to_version_15, the 13→15 and 14→15 upgrade test fails: no Core read, stale keys kept. With it, it passes.
The hash-collision regression tests fail against v1 as first committed. The payout-equals-node-id case fails with "key to disable with specified ID is not found", which is the chain halt the review reproduced. The new-identity case keeps a duplicate-hash node-id key. Both pass with the fix.
After the bot review, three tests fail against the previous fix:
the collision test now requires every key to be added, including a signable payout equal to an earlier node id (9f9f…), and the previous fix left keys out;
the new-identity test requires its node-id key, which the previous fix dropped;
in the PV14 node-id test, the payout key stays disabled after the upgrade.
With the ABCI guard removed but DRIVE_VERSION_V10 still selecting Drive v0, the collision test fails with IdentityKeyAlreadyExists. With Drive v1 and the reconciliation covering every masternode, all three pass.
With Drive v1's same-call de-duplication disabled, should_add_two_keys_with_one_hash_in_one_call fails with "insertion order error" (a duplicate operation in a consistency-checked batch). Restored, it passes.
With the new parent-tree de-duplication in apply_drive_operations 2 removed, the Drive and upgrade-block shared-hash tests fail with "insertion order error" under consistency checks. With it, they pass, and protocol 14 still refuses the checked batch, as before.
Rotate and restore (F2): should_take_the_payout_core_reports_for_an_operator_key_change_printed_without_one covers a new identity and a returning identity with the payout restored inside one Core height range, and a reset. It also asserts that Core is asked only about those entries. It fails before (the new identity gets no payout key) and passes with the Core read.
The new Core read: with ProTxHash::to_hex in the request, should_ask_protx_info_for_the_masternode_at_the_block_of_the_height (a real JSON-RPC connection) fails, because Core receives the reversed hash. With Core's form it passes. The same test reads an answer with "operatorReward": 13.37, which rust-dashcore's typed answer cannot read; the reviewer reproduced that failure against mainnet Core.
New tests:
Payout set, changed, cleared on a key change, and with a key change.
A switch back to a retired identity; a re-sent payout; the revived height kept; a payment-only diff leaving the state clean; payout and node id colliding with other keys' hashes.
V24 taken from the Core fork record through update_core_info (recorded earlier, in this block, not active; Core is asked only by the record step).
v1 units: idempotence, a clear, two keys added in one update, a key change to new and existing identities, a missing identity.
Reconciliation units: stale payouts fixed on current identities, evonodes included; membership mismatch, Core error and malformed answers fail.
Drive units for add_new_keys_to_masternode_identity (consistency checks on): a hash the identity already references (fails at 14, added from 15), two keys with one hash in one call, a unique-key hash (no reference at 14 and 15).
A guard that every protocol version selecting update_operator_identity 1 selects Drive add_new_keys_to_masternode_identity 1 or later.
Several identities adding keys of one new hash in one batch, in Drive and in the upgrade block, with consistency checks on and off; an identity at the last key id reconciling without a new id; estimates counting one reference per hash.
Upgrade block: from 13 and from 14; the upgrade to 14 does not reconcile; the block's own diff after the reconciliation (key change, payout, removal, addition); a retried round.
A 1-14 freeze test of the selected generations.
The six operator-key-encoding scenarios now also run at 15, with V24 recorded the way update_core_info 1 records it. The latest() tests that assert the old semantics run at 13 and 14. The mainnet fixture tests (test_update_masternode_list, should_build_the_validators_earlier_binaries_built_from_mainnet_masternode_lists) pass at 13 and at latest.
Ran locally:
cargo test -p drive-abci --lib: 4554 passed, 17 ignored, after the F2 fix (before the merge of v5.1-dev's latest three commits; after it, core_based_updates, protocol_upgrade, identity_create and the shield nullifier tests pass, 495). Earlier: 4536 passed, 17 ignored, and 2 failed. The 2 failures were two shield tests that upgrade from 13 and needed a Core answer. I fixed them after that run's binary was built, and a re-run of those two plus core_based_updates and protocol_upgrade passed (227). After merging v5.1-dev (fix(drive-abci)!: re-enable the voter key of the address a masternode returns to (PV15) #5768), core_based_updates and protocol_upgrade pass again (221).
the full strategy-test binary (RUST_MIN_STACK=4194304): 124 passed, 4 ignored, before and after the strategy mock change and after each round of review fixes.
cargo test -p drive --lib: 4358 passed, 6 ignored.
cargo test -p platform-version: all pass.
CI-style clippy (--all-targets --all-features --locked -- --no-deps -D warnings) on drive-abci and platform-version: clean. cargo fmt --all --check: clean.
A multi-agent code review covered consensus determinism, upgrade-block failure modes, versioning and in-place rules, and tests. Its must-fixes are folded in: the hash-collision chain halt, a stale book paragraph, broken shield tests, and missing tests.
Breaking Changes
Consensus change at protocol version 15: operator payouts follow Core's diffs, an operator key change printed without a payout reads the payout from Core (protx info, which needs the dashmate whitelist migration), operator identities' TRANSFER keys are reconciled with them, and the first block of protocol version 15 reads Core's full masternode list. The Rust signature of perform_events_on_first_block_of_protocol_change gains a parameter and a CoreRPCLike bound. Protocol versions 1 to 14 are unchanged.
Out of scope
A payout cleared by a ProUpServTx with an empty script, without an operator key change, is still invisible in protx listdiff (pre-existing, spec F3). The next printed payout heals it.
Open items
Rehearse the reconciliation on live state before release. Load a testnet node's and a mainnet node's stored platform state, call protx listdiff 1 h, and check four things: membership, that every entry parses, the correction count, and that every current operator identity exists (all of them are now reconciled, and a missing one fails the block). Also time the identity work. A membership mismatch or a parse error fails the upgrade block on every node, and the masternode list is outside the app hash, so a past divergence would not have shown.
Withdrawal keys the upgrade disables. The upgrade block disables every enabled TRANSFER key that Core's payout does not grant, even where the stored payout already equals Core's (for example, a key inherited through a v0 switch). That is intended, but count these on the snapshot, since such identities may hold balances.
RPC timeout headroom. The Core RPC client times out after 15 s and retries. The measured cold call is 4.45 s; measure on minimum-spec evonode hardware.
Dashmate tests not run locally. The new migration test needs a wasm-dpp build here; CI's "JS packages (dashmate) / Tests" runs it.
CheckTx may wait. For those seconds, CheckTx calls that need Core (instant lock verification) wait behind the full-list call on the shared Core connection.
Possible rust-dashcore follow-up: its typed get_protx_info sends ProTxHash::to_hex() (byte-reversed against Core's form), and its ProTxInfo reads operatorReward as an integer, while Core prints a decimal. Drive calls protx info directly and reads only state; with those fixed upstream it could use the typed client again.
Possible dashpay/dash follow-up: a lossless protx listdiff that prints the final operator payout whenever it prints an operator-key change, including unchanged payouts and explicit clears, would make the protx info read unnecessary at a later protocol version.
Not done (possible follow-up): since the upgrade block now reads Core anyway, it could also close the V24 record's window in the same block.
Pre-existing and unchanged: a P2SH operator payout becomes an ECDSA_HASH160 key nobody can sign, and an evonode reset leaves a zero platform node id key (Q6). Neither affects balances.

…de diffs at protocol 15
Platform took a masternode's operator payout only from its full state (the init
chain list, or a masternode new in a diff), so a payout set or changed in Core
afterwards never reached the stored list or the operator identity's TRANSFER key.
A ProRegTx carries no operator payout, so nearly every masternode registered after
Platform genesis with an operator reward has an operator identity without a
TRANSFER key. And a new operator identity inherited the previous operator's payout
key (update_operator_identity v0's fallbacks).
PV15 only (DRIVE_ABCI_METHOD_VERSIONS_V11, unreleased):
- update_masternode_list 2 / update_state_masternode_list_v2: keeps a diff's
operator payouts; an operator key change Core prints without a payout clears the
payout (Core empties it on every key change and prints nothing for the clear);
keeps revived heights a diff does not print (DMNState::apply_diff); reads whether
V24 is active from the Core fork record instead of asking Core.
- update_operator_identity 1: reconciles every TRANSFER key of the identity it
updates with the payout (reuse the matching key, disable every other enabled
TRANSFER key, add if none), with no fallback to an earlier operator's key. It is
idempotent, so a payout Core re-sends cannot add a duplicate key and halt the
chain, and a switch back to a retired identity disables a foreign key.
PV1-14 keep update_masternode_list 0/1 and update_operator_identity 0; their files
are unchanged. The latest() tests asserting the old semantics are re-pinned to 13
and 14, with PV15 counterparts; the operator key encoding scenarios now also run at
15, with V24 recorded as update_core_info 1 records it.
Red/green (operator_payout_tests, at latest()):
- before any fix: all 5 fail (payout key not added, new operator inherits P0,
retired identity keeps P0, revived height cleared);
- list v2 with update_operator_identity still 0: the re-sent payout test fails
with IdentityKeyAlreadyExists (the chain halt) and the switch-back test fails;
- with update_operator_identity 1: all pass.

…first block of protocol 15
Earlier protocol versions left stale operator payouts in Platform's masternode
list and stale TRANSFER keys on the operator identities: a payout set or changed
after Platform first listed a masternode never arrived, and a new operator
inherited the previous operator's payout key. Following Core's diffs from PV15 on
fixes only what changes afterwards, and an operator re-sending the address they
already set prints nothing, so those identities would stay wrong.
transition_to_version_15 now reads Core's full masternode list (protx listdiff 1
c_prev) at the last committed chain locked core height, the height Platform's
list is at when the upgrade hook runs, before this block's own diff. Where a
stored operator payout differs from Core's, it stores Core's and runs the
masternode's current operator identity through update_operator_identity 1 with
it, which reconciles every TRANSFER key. No GroveDB record: the first block of a
protocol version is unique by construction, and a jump from 13 or 14 to a later
version passes through the same ladder step. c_prev is chain locked and was
already processed by an earlier block, so every validator's Core holds it and
reports the same list. A Core error, or a Core list whose masternodes are not
Platform's, fails the block.
perform_events_on_first_block_of_protocol_change gains block_platform_state and a
CoreRPCLike bound, passed through all three generations unchanged; only
transition_to_version_15 (PV15, unreleased) uses them. Tests that run the
protocol 15 upgrade on a platform without masternodes get a mock Core that lists
none (TempPlatform::with_no_core_masternodes).
Red/green (operator_payout_reconciliation_tests): with the reconciliation call
removed from transition_to_version_15, the PV13->15 and PV14->15 upgrade test
fails (no Core list read, stale keys kept); with it, both pass.

…protocol 15 reconciliation
Folds in a multi-agent review of the two previous commits.
update_operator_identity 1 (PV15 only), a chain halt the review reproduced: the
platform node id step matched keys by data alone, of any kind, while the payout
step matched TRANSFER keys. An operator can set a payout equal to its platform
node id (any 20 bytes are a valid payout), and a later diff changing both then
queued one key id twice in one DisableIdentityKeys, which fails on every node.
Each step now touches only its own kind of key (the BLS operator key, the
SYSTEM/EDDSA platform node id key, the TRANSFER keys), and no key is added whose
public key hash the identity already holds: Drive refuses a key whose hash its
identity holds a reference for, and which keys hold one depends on how they were
added. A new identity gets no second key of a hash either.
Reconciliation in the first block of protocol 15:
- a membership mismatch names the first ten masternodes on each side and logs;
- a Core list that names a masternode twice fails as a bad response;
- the Core read goes first in transition_to_version_15, so a round whose Core
cannot answer stops before the contract work;
- the helper's doc says it is frozen with protocol 15 and relies on
update_operator_identity 1 or later; its visibility is narrowed.
Tests and mocks: two shield tests that upgrade from 13 get an empty Core list;
with_no_core_masternodes answers full lists only; the strategy mock answers a
full list at a later height with the strategy's list there; the tests of the
now-frozen update_operator_identity v0 and update_state_masternode_list v1 are
pinned to 14; the version test is a 1-14 freeze test. New tests: two keys in one
update, v1 identity switches, payout or node id repeating another key's hash,
the upgrade block's own diff after the reconciliation, a retried upgrade round,
a payment-only diff leaving the state clean, malformed Core lists, an evonode.
Book: the upgrade-window paragraph of core-fork-activations.md says why the
protocol 15 upgrade block reads Core once anyway.
Red/green: against update_operator_identity v1 as first committed,
should_not_halt_when_an_operator_payout_or_node_id_repeats_another_keys_hash
fails with "key to disable with specified ID is not found" (the halt) and
should_create_a_new_operator_identity_whose_payout_equals_the_platform_node_id
keeps a duplicate-hash key; with this commit both pass.

The changes add versioned masternode-list and operator-identity updates, Drive key-insertion behavior, and protocol 15 reconciliation with Core’s masternode list. They also update Core RPC access, configuration, tests, and architecture documentation.
Drive adds versioned masternode key insertion. Version 1 avoids duplicate non-unique hash references, including duplicates earlier in the same call. Batch operation application removes duplicate tree-creation inserts. Version tables select the behavior, and tests cover hash reuse and key insertion.
Versioned masternode list and identity updates packages/rs-drive-abci/src/execution/platform_events/core_based_updates/update_masternode_identities/update_operator_identity/*, packages/rs-drive-abci/src/execution/platform_events/core_based_updates/update_masternode_list/*, packages/rs-platform-version/src/version/drive_abci_versions/drive_abci_method_versions/v11.rs
List update version 2 processes Core diffs, filters unchanged operator keys using V24 activation records, updates stored masternode and validator state, and fetches payouts for relevant key changes. Operator identity version 1 reconciles payout and node-ID keys. Tests cover version selection, payouts, identity changes, and V24 cases.
The protocol 15 transition reads Core’s full masternode list at the last committed Core height and reconciles stored payouts and operator TRANSFER keys. Core-list errors and mismatches stop reconciliation. The Core RPC interface adds a height-specific masternode-state read. The default RPC whitelist and its migration include protxinfo. Version settings, test support, and architecture documentation are updated.

Merge Risk: Minimal · previous review 68108
This change makes Platform follow Core operator payout changes from protocol 15, and reconciles operator TRANSFER keys once on the first protocol-15 block. The two earlier review concerns, key ID allocation and estimation of same-hash keys, are fixed and covered by regression tests. No concrete merge-blocking risk remains in the supplied context. The author's open items (live-state rehearsal and RPC timeout measurements) are normal pre-release validation.

Final validation — Phase 1 + Phase 2
Verified head 3a96278 and confirmed three blocking correctness issues: ambiguous Core diffs can remove valid payout authority, the upgrade repair can skip historically disabled withdrawal keys, and hash-collision handling can discard a valid payout key. The protocol-version gating and transaction-scoped upgrade orchestration are otherwise consistent with the project conventions. All current code checks pass, with PR Hygiene pending; validation here was static, with no local builds or tests run.
Triage: critical by gpt-6.1-sol (effort low) — The intricate changes to update_operator_identity/v1 and reconcile_operator_payouts_with_core modify withdrawal-authorizing identity keys and persisted consensus state, while protocol-15 activation introduces a one-time repair.
These findings are from an automated code review. Verify each finding against the current code and only fix it if needed.

- [BLOCKING] packages/rs-drive-abci/src/execution/platform_events/core_based_updates/update_masternode_list/update_state_masternode_list/v2/mod.rs:209-214: Resolve ambiguous payout omissions instead of inferring a clear
An omitted payout does not establish that the target Core state has no payout. Dash Core v23.1.3's `protx_listdiff` calls `baseBlockMNList.BuildDiff(blockMNList)`, and `CDeterministicMNStateDiff` includes a field only when its endpoint values differ. Starting at `(operator A, payout P)`, rotate to B and let B restore P before Platform next advances its Core height. The resulting diff reports B but omits the payout because both endpoint payouts are P. Platform permits multi-height advances, so this branch fabricates `Some(None)` for a valid history. The identity update then creates B without a TRANSFER key, or disables B's existing TRANSFER keys when B names a returning identity, despite Core authorizing P. Re-sending unchanged P does not generate a payout change to repair it.
The same omission also hides an actual payout clear made by a ProUpServTx without an operator-key change. That direction predates this PR, but the new inference does not resolve it. Core's `CDeterministicMNStateDiff::ToJson` still emits nothing when the changed payout script is empty, in both the inspected release and current default source. The pinned and current rust-dashcore decoders already support an explicit empty-string clear; they cannot reconstruct information Core omits.
Resolve ambiguous updates against authoritative state at the target chain-locked height rather than interpreting omission as a clear or blindly retaining the old payout. Add regressions for rotation followed by restoration of the same payout within one queried interval and for a service-update payout clear. The serialization repair belongs in dashpay/dash; if deferred, link a tracking issue or PR for explicit clears and a recorded-response regression. rust-dashcore #1179 documents the limitation but does not fix Core's output, and corrected output must be consumed at a protocol boundary.

- [BLOCKING] packages/rs-drive-abci/src/execution/platform_events/core_based_updates/reconcile_operator_payouts_with_core/mod.rs:115-117: Check identity keys even when the stored payout already matches Core
Payout equality does not establish the historical identity-key invariant asserted in this method's documentation. Under PV14, an evonode with stored payout P can change its platform node ID to P and subsequently change the node ID again without changing the payout. `update_operator_identity_v0` identifies node-ID keys solely by `key.data()`, without checking purpose or key type. The first update reuses the existing TRANSFER key as the matching node-ID key; the second disables that TRANSFER key because its bytes match the old node ID P. Both Platform's stored payout and Core's payout remain P throughout.
This filter excludes that identity from the one-time repair, leaving its valid withdrawal key disabled after the upgrade. Payment-only diffs do not invoke operator-key reconciliation, so routine subsequent blocks do not heal it. This is directly within the new migration's responsibility to repair current operator keys, rather than a request to change historical execution.
Inspect and reconcile current operator identities independently of whether their cached payout bytes need changing. Keep the optimization of rewriting masternode-list entries only for actual payout changes. Add a PV14-to-PV15 regression that performs the node-ID collision sequence and verifies that P's TRANSFER key is re-enabled.

Holding a hash is not equivalent to holding an enabled key authorized for the requested purpose. For example, choose a signable P2PKH payout H that was previously used as the identity's platform node ID, then change the node ID and later set the payout to H. The disabled SYSTEM/EDDSA node-ID key still contributes H to `held_hashes`. Payout reconciliation disables the previous TRANSFER key, but this guard refuses to add H's ECDSA_HASH160/TRANSFER key. Core stores a valid payout while Platform leaves the identity without enabled withdrawal authority. The collision tests currently accept omission rather than asserting that the authorized payout remains usable.
The underlying restriction is Drive's non-unique hash-to-identity reference insertion: `insert_non_unique_public_key_hash_reference_to_identity_operations_v0` rejects an existing `(hash, identity_id)` reference. That secondary index does not require removing the distinct purpose-specific key itself; masternode identity creation already stores keys without registering those external references. The book's “Where code goes” assigns index maintenance and GroveDB operations to rs-drive, so compensating for this storage restriction by dropping authority in ABCI crosses the ownership boundary as well as breaking withdrawals.
Add protocol-15-selected Drive handling that reuses existing hash-to-identity references, including references queued within the same batch, while preserving distinct purpose-specific keys. ABCI should reconcile Core's authority without discarding the payout key. Add a regression using a signable payout equal to a disabled node-ID hash and assert an enabled TRANSFER key, not only successful block execution.

…every operator identity at protocol 15
Addresses the three blocking findings of the bot review of #5775.
Operator keys whose hash another key already has (PV15 only): the previous commit
left out a key whose public key hash the identity already held, which avoided
the chain halt but could drop real withdrawal authority. Example: a signable
P2PKH payout H that was the platform node id before; the disabled node id key
holds H, so the TRANSFER key for H was never added. The restriction is Drive's:
adding a masternode key fails with IdentityKeyAlreadyExists when the identity
already holds a non-unique key hash reference for its hash. New Drive slot
add_new_keys_to_masternode_identity (0 in every shipped table, 1 in
DRIVE_VERSION_V10, PV15-only): v1 adds such a key, and a second key of one hash
in the same call, without a second reference; each key keeps its own id and
purpose. update_operator_identity 1 no longer leaves any key out and keeps only
the per-kind filters that stop one key from being disabled twice.
Reconciliation in the first block of protocol 15: every masternode's current
operator identity now goes through update_operator_identity 1 with Core's payout,
not only those whose stored payout differs. Up to protocol 14 a platform node id
matched keys by data alone, so an evonode whose node id once had its payout's
bytes can have its payout key disabled while the stored payout and Core's agree.
The stored list is still rewritten only where the payout changed.
Not changed, by decision: inferring a payout clear from a key change printed
without a payout (spec F2, accepted).
In place: the dispatcher of add_new_keys_to_masternode_identity_operations reads
the new slot instead of add_new_keys_to_identity; both are 0 in every shipped
table, so PV1-14 select the same v0.
Red/green:
- should_add_an_operator_payout_or_node_id_key_that_repeats_another_keys_hash
and should_create_a_new_operator_identity_whose_payout_equals_the_platform_node_id
fail against the previous commit (keys left out); with the guard removed but
DRIVE_VERSION_V10 still selecting v0, the first fails with
IdentityKeyAlreadyExists (the halt); with Drive v1 both pass.
- should_re_enable_a_payout_key_an_earlier_node_id_change_disabled_in_the_first_block_of_protocol_version_15
fails against the previous commit (payout key stays disabled) and passes now.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ule, and test its version 1
Folds in a review of the previous commit.
- The masternode key-add method has its own version slot now, so its dispatcher,
v0 and v1 move to add_new_keys_to_masternode_identity/ (one method, one
directory). The v0 body is moved unchanged.
- Drive tests through AddNewKeysToMasternodeIdentity, with batch consistency
checks on: a key whose hash the identity already references fails with
IdentityKeyAlreadyExists at protocol 14 and is added from 15; two keys with one
hash in one call are both added under one reference; a key with another
identity's unique key hash gets no reference at 14 and 15 alike.
- v1's same-call de-duplication is one `insert` term (its earlier `contains`
check was redundant).
- A guard test that every protocol version selecting update_operator_identity 1
selects add_new_keys_to_masternode_identity 1 or later.
- The upgrade-block test asserts a masternode whose payout already matches Core
keeps its keys and is not rewritten.
- Doc fixes: the field, dispatcher, V10 and note 23 texts name the same-call case,
the owner and voter keys, and the slot protocol 14 keeps.
Red/green: with the de-duplication term replaced by `true`,
should_add_two_keys_with_one_hash_in_one_call fails with "insertion order error"
(a duplicate operation in a consistency-checked batch); restored, it passes.

Re-review — Final validation — Phase 1 + Phase 2
At head 32ff7a4, the prior key-omission and incomplete-reconciliation findings are fixed, but two blockers remain: ambiguous payout omissions can revoke valid withdrawal authority, and shared payout hashes produce duplicate index-tree operations across identities. This was a static verification; no builds or tests were run. Current CI reports no failed code checks, with Rust workspace tests and the JS build still pending; wasm32, Kotlin, and Swift schema checks passed.

- [BLOCKING] packages/rs-drive/src/drive/identity/update/methods/add_new_keys_to_masternode_identity/v1/mod.rs:42-43: Deduplicate hash-index parent trees across the complete Drive batch
`referenced_hashes` covers only one identity operation, while the non-unique hash parent tree is shared across identities. Consider two masternodes registered without payouts whose operators set the same previously unindexed payout H before PV15. Earlier protocols ignore those payout changes, so reconciliation queues an `AddNewKeysToMasternodeIdentity` operation for each identity. `apply_drive_operations_v2` lowers both operations before applying either; both calls see H absent and independently queue the same parent-tree insertion through `insert_non_unique_public_key_hash_reference_to_identity_operations_v0`, alongside their distinct identity leaves.
Neither the subsequent alias coalescing nor the low-level batch conversion removes these parent duplicates. Both pinned and current GroveDB consistency checkers reject identical repeated operations. Consequently, `batching_consistency_verification=true` makes `grove_apply_batch_with_add_costs_v0` return `GroveDBInsertion("insertion order error")`, preventing that validator from executing or replaying the mandatory upgrade block. The default false setting skips this rejection, so this is configuration-dependent execution failure, not an unconditional default-network halt. Ordinary PV15 diffs that add one fresh shared payout to two existing identities can reach the same path.
Track pending hash-parent creation across the complete version-selected Drive batch and emit the parent once while retaining both identities' keys and distinct `(H, identity_id)` entries. Keep index maintenance in Drive rather than suppressing keys or references in ABCI. Add a two-identity Drive regression and an upgrade-reconciliation regression with a shared fresh payout, exercising both consistency settings; the existing same-call test covers only one identity operation.

(existing thread: https://github.com/dashpay/platform/pull/5775#discussion_r4479658908)
An omitted payout is not authoritative evidence of a clear. Dash Core v23.1.3's `protx_listdiff` compares endpoint lists, and `CDeterministicMNStateDiff` sets the payout bit only when the endpoint scripts differ. Starting at (A, P), rotating to B, and restoring P before the target height therefore reports B without a payout. This branch converts that valid history into `Some(None)`.
This also regresses returning identities, rather than merely leaving a new identity incomplete: if retired B already holds an enabled TRANSFER key P, `reconcile_operator_payout_keys_v1` disables it even though Core authorizes P. The previous generation's returning-identity path retained that key. Accepting F2 because nobody gains unauthorized access does not address this loss of withdrawal access to B's existing balance; changing to a different payout is an additional on-chain recovery operation.
Resolve the target payout from authoritative chain-locked state before reconciling authority, or consume corrected Dash Core output at the protocol boundary. The Core repair must report the target payout whenever an operator-key change is reported, including unchanged nonempty payouts and explicit clears. Printing empty-script clears alone cannot fix equal endpoints because their payout bit is never set; the current Core default source retains that endpoint comparison. No concrete follow-up is linked in the supplied discussion, and tracking alone would not remove this newly introduced regression. Add a multi-height rotation/restoration regression that returns to B and asserts that its Core-authorized P key remains enabled. This request does not include the separate pre-existing service-only payout-clear issue.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
Payout clearing is inferred only from a surviving operator-key change. Because the supplied contract says Core omits an emptied payout, an aggregate diff that hides an intervening operator-key reset may leave Platform's previous payout and TRANSFER key authorized.
Platform can keep payout P and its enabled TRANSFER key even though Core's payout is empty.
This can occur when: Between two Platform-observed Core heights, operator key A changes to B and back to A, clearing payout P, with no replacement payout. The resulting diff omits the net-unchanged key, or key normalization drops it.

…t protocol 15
Folds in the bot's re-review of #5775 and two CodeRabbit comments.
Shared payout hashes (PV15 only): each identity operation is lowered on its own,
against stored state, so several identities adding a key of one hash no identity
held before, in one batch, each queue that hash's tree under the non-unique key
hashes tree. Masternodes whose operators share a payout address do exactly that
in the protocol 15 reconciliation, and ordinary diffs can too. A batch checked
for consistency (batching_consistency_verification) refuses the repeated insert
with "insertion order error"; the default, unchecked, keeps the last of the
identical inserts. apply_drive_operations 2, which only DRIVE_VERSION_V10
(protocol 15) selects, now keeps the first of those identical inserts after
lowering; every identity keeps its own key and entry.
update_operator_identity 1 takes a new key id only for a key it adds, so an
identity at the last key id can still have keys reused, disabled or re-enabled.
add_new_keys_to_masternode_identity 1 estimates one reference per hash of a
call, as it applies one.
Red/green:
- should_add_keys_of_one_new_hash_to_several_identities_in_one_batch (Drive,
consistency checks on) and should_reconcile_masternodes_that_share_a_new_payout_in_one_batch
(upgrade block, checks on and off) fail with "insertion order error" with the
new de-duplication call removed, and pass with it; protocol 14 keeps failing
the checked batch, as before.

Overflow when the key id is taken up front; should_estimate_one_reference_for_two_keys_with_one_hash
fails when the estimate assumes a reference per key.

Re-review — Final validation — Phase 1 + Phase 2
At head 4dfba79, three prior findings are fixed: Drive coalesces shared hash-parent inserts, purpose-specific keys survive hash collisions, and upgrade reconciliation checks every current operator identity. One blocker remains: the new omission-to-clear inference can remove legitimate withdrawal authority for a valid multi-height Core history. This was a static review with no builds or tests run; current CI shows Rust workspace tests and the JS build in progress, with no failed code checks observed.

(existing thread: https://github.com/dashpay/platform/pull/5775#discussion_r4479658908)
An omitted payout does not establish that the target Core state has no payout. Starting at operator A with payout P, Core can rotate to B and B can restore P before Platform next advances its Core height. Platform accepts multi-height advances, and Core's `protx_listdiff` compares the two endpoint lists. In both v23.1.3 and current develop, `CDeterministicMNStateDiff` selects the payout field only when its endpoint scripts differ. This history therefore reports B without a payout field, which these lines convert into `Some(None)` despite the target state authorizing P.
That fabricated clear reaches `update_operator_identity_v1`, which creates a new B identity without a TRANSFER key or disables a returning B identity's existing TRANSFER keys. Routine payment-only diffs do not reconcile those keys, and re-sending unchanged P produces no payout change. Recovery requires another L1 payout change. This is loss of authorized withdrawal availability, not theft or a consensus split; the one-time upgrade reconciliation cannot repair histories occurring afterward.
The F2 acceptance explains the intended scope but does not make this newly introduced inference correct. The proposed Core change to print explicit empty-string clears is insufficient for this history: equal endpoint payouts never select the payout field, so payout serialization does not run. Resolve ambiguous entries against authoritative state at the target chain-locked height, or coordinate a dashpay/dash RPC contract that reports the final payout whenever it reports an operator-key change, including unchanged nonempty payouts and explicit clears, with protocol-versioned consumption in Platform. Add a regression for rotation followed by restoration of the same payout within one queried interval. The description's possible upstream follow-up has no linked tracker covering this complete repair.
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.
Track service-only payout clears that retain withdrawal authority — Core's released and current diff JSON omit an emptied operator payout because ExtractDestination fails for the empty script. Without an operator-key change, Platform preserves the old payout and its TRANSFER authority. This predates the PR, but it leaves a former payout key authorized after Core clears it and warrants a separate security follow-up.
Follow-up: A separate dashpay/dash issue and repair PR should make payout clears explicit in listdiff responses; a coordinated Platform follow-up should consume the corrected response at a protocol boundary and test service-only clears.
…from Core at protocol 15
Closes the last blocking finding of the bot review of #5775 (spec F2), as Ivan
decided.
Core empties the operator payout on every operator key change and prints no
field for it, and `protx listdiff` prints a payout only when it differs between
the diff's two heights. So a key change printed without a payout does not tell
whether the new operator set a payout again inside the same Core heights, maybe
the very one the masternode had (rotate and restore). update_state_masternode_list_v2
inferred a clear there, which left a new operator identity without its payout
key and disabled a returning identity's key although Core grants it. It now
reads that masternode's state from Core at the block's chain locked height
(new CoreRPCLike::get_masternode_state: getblockhash(c), then protx info at that
hash) and takes its operator payout. Only entries with an operator key change
and no printed payout trigger the call: about one per operator key change, 31 on
mainnet since Platform's genesis. A Core error fails the block, as other Core
reads do.
dashmate: Core refuses the method to drive's consensus RPC user until its
whitelist names it, so `protxinfo` joins the default whitelist and a
5.1.0-beta.1 migration adds it to existing configs (a user without a whitelist
already may call every method), with a migration test.
Mocks: the strategy tests' Core answers the strategy's own state of a masternode
at a height; the recorded-fixture tests answer the recorded states (MN_L3's key
change emptied its payout). The V24-not-active case of
should_take_v24_from_the_core_fork_record now expects MN_L2's real payout, which
a re-encode keeps, instead of the inferred clear.
Red/green: should_take_the_payout_core_reports_for_an_operator_key_change_printed_without_one
(a new identity and a returning identity with the payout restored inside one
Core height range, and a reset; Core asked only about those entries) fails
before (the new identity gets no payout key) and passes after.

Verified the exact head 68108ea: all four prior findings are fixed, but the new mandatory protx info lookup rejects valid fractional operator rewards and can prevent Core-height advancement. One non-blocking suggestion remains to track lossless payout reporting in Dash Core. Validation was static only; current CI shows Rust workspace tests, the JS build, and Drive/RS-DAPI images passing, with Dashmate-helper, Evo SDK/Dashmate tests, and the Swift build still pending.
Triage: critical by gpt-6.1-sol (effort low) — The intricate changes in update_operator_identity/v1, reconcile_operator_payouts_with_core, and update_state_masternode_list/v2 alter withdrawal-authorizing identity keys, protocol-gated consensus execution, and persisted-state repair.
These findings are from an automated code review. Verify each finding against the current code and only fix it if needed.

- [BLOCKING] packages/rs-drive-abci/src/rpc/core.rs:566-567: Support fractional operator rewards before requiring protx info
The new lookup deserializes the entire response into rust-dashcore's ProTxInfo before extracting state. In pinned revision c9aeac0d0dcb, rpc-json/src/lib.rs:3356 declares operator_reward as an ordinary u32; the inspected upstream default has the same declaration. Dash Core accepts two-decimal-place rewards and serializes operatorReward as (double)nOperatorReward / 100. Valid fractional values therefore fail deserialization. The repository's mainnet fixture already contains 13.37 and 2.5 rewards, including packages/rs-drive-abci/tests/supporting_files/mainnet_protx_list_diffs/1-2128896.json:20642.
A masternode owner can register with a fractional reward and rotate its operator key while leaving the operator payout empty. The diff reports the key change without a payout, causing update_state_masternode_list_v2 to require this lookup. The decoding error propagates into block execution, so honest validators cannot execute proposals advancing across that Core change. Retries do not repair the response, and later endpoint diffs remain affected while the changed operator key and omitted payout persist. This needs neither validator voting power nor a compromised RPC server.
Correct the response representation in dashpay/rust-dashcore and update Platform's dependency pin, or provide an upstream response type that decodes only the required hash and state. Add a recorded-response regression with a fractional operatorReward through the actual RPC decoder. The new MockCoreRPCLike tests return DMNState directly and bypass this boundary; do not suppress the error or substitute an empty payout.

The historical lookup belongs in this node-side orchestration and resolves the key-change ambiguity, but it compensates for missing information in dashpay/dash's RPC output. In both inspected v23.1.3 and develop sources, CDeterministicMNStateDiff::ToJson omits an empty operator payout. Endpoint comparison also omits a payout restored to its original value during an operator rotation. The pinned and current rust-dashcore decoders already support explicit clears, so another decoder change cannot reconstruct that missing information.
Link a dashpay/dash tracking issue or PR for lossless payout reporting in src/evo/dmnstate.cpp and src/rpc/evo.cpp: emit explicit clears and include the target payout alongside reported operator-key changes, using RPC enrichment from the target list where necessary without changing historical binary diff semantics. Include recorded-response coverage and consume corrected output at a Platform protocol boundary. rust-dashcore #1179 documents the omission but does not repair it, and neither the supplied discussion nor the upstream searches provided a matching repair link.
That follow-up should also cover the pre-existing service-only empty-script clear: without an operator-key change, this lookup is skipped and Platform can retain the previous TRANSFER authority. This suggestion requests tracked upstream ownership, not expansion of this PR to implement that separate repair.

…rnode
Folds in two reviews of 5304afa and the bot's re-review of #5775. Both
defects below would have failed, on every node, the first protocol 15 block with
an operator key change printed without a payout (every revocation included).
- The hash was sent byte-reversed. rust-dashcore's get_protx_info sends
ProTxHash::to_hex, which reverses the bytes against Core's form, and Core
answered that no such masternode exists. get_masternode_state now calls
`protx info` itself with the hash as Core prints it, and checks the answer is
for that masternode.
- The answer could not be read for every masternode. rust-dashcore's ProTxInfo
reads operatorReward as an integer, while Core prints a decimal (13.37 and 2.5
on mainnet), and its metaInfo holds node-local numbers. Only the answer's
`state`, the state protx listdiff lists, is read now.
drive-abci also refuses to start when Core refuses protx info (HTTP 403), as it
does for getspecialtxes: Core loads the consensus user's whitelist only when it
starts, and a Core not restarted since the dashmate migration would otherwise
fail the first such block, possibly weeks after activation.
Tests: protx info over a real JSON-RPC connection, asserting the params Core
receives and reading an answer with a 13.37 % reward; the answer for another
masternode or without a state refused; a Core error fails the list update and
applies nothing; an unlisted masternode's entry asks Core nothing; protocol 13
and 14 never ask for a masternode's state; drive-abci's startup check with Core
answering and refusing protx info.
Red/green: with ProTxHash::to_hex in the request,
should_ask_protx_info_for_the_masternode_at_the_block_of_the_height fails (Core
receives 9b8508da...cc02 for 02cc32ac...859b); with Core's form it passes.

…d log the startup probe's answer
Folds in a review of c5eef1a: the protx info request test takes MN_L2's hash
from Core's decoded masternode list, as block execution has it, rather than
from the string it asserts; the startup probe logs an answer other than HTTP
403; note 24 says the read is only for operator key changes the diff prints
without a payout.

Re-review — Final validation — Phase 1 + Phase 2
Verified the complete diff at a20b9e4: the five prior blocking findings are addressed, and no additional blocking defect was confirmed. Two non-blocking suggestions remain to establish tracked upstream ownership for the Dash Core payout-reporting limitation and rust-dashcore RPC defects. This was a static review; current CI shows all reported code checks passing, with only PR Hygiene pending, and the supplied base drift reports no conflicts.

- [SUGGESTION] packages/rs-drive-abci/src/rpc/core.rs:567-575: Track the protx-info wire-contract repair in rust-dashcore
This adapter safely fixes Platform's immediate lookup, but it bypasses two defects in the shared RPC client. Both pinned rust-dashcore c9aeac0d0dcb and inspected default 6bb43e15b42d still send protx_hash.to_hex() from get_protx_info and declare ProTxInfo.operator_reward as u32. ProTxHash's forward display differs from that inner-hash serialization, and Core accepts fractional rewards, so other consumers retain the request-hash and response-decoding failures avoided here.
Link a dashpay/rust-dashcore issue or PR to correct get_protx_info's hash serialization and provide decimal-compatible response decoding or a typed state-only API. Include the request-parameter and fractional-reward regressions at that shared boundary. rust-dashcore #1179 addresses list-diff decoding, not these defects. Keeping the safe projection in DefaultCoreRPC while an upstream repair is pending is reasonable; the missing piece is a tracking reference, not another local workaround.

(existing thread: https://github.com/dashpay/platform/pull/5775#discussion_r4490341024)
The open-items bullet acknowledges the correct owner, but there is still no linked dashpay/dash issue or PR tracking the repair. The historical lookup correctly resolves operator-key changes; it remains necessary because Core's endpoint diff omits restored-to-original payouts, while CDeterministicMNStateDiff::ToJson omits empty payouts in both v23.1.3 and current develop. A service-only clear therefore still bypasses this lookup and can leave the previous TRANSFER authority enabled.
Core's current protx_listdiff already enriches address information from the target masternode state, so payout enrichment can likewise be repaired at the RPC boundary without changing historical binary diff semantics. Link a dashpay/dash follow-up covering explicit clears and the final payout alongside reported operator-key changes, with response regressions for rotate-and-restore and service-only clears. Platform should adopt the corrected output at a future protocol boundary. This requests tracked upstream ownership before deferral, not implementation of the separate Core repair in this PR.

Issue being fixed or feature implemented
Fixes #5440 (plan item C3).
Platform keeps its own copy of Dash Core's masternode list. It builds the copy from Core's full list at init chain, then applies Core's
protx listdiffdiffs block by block. Each masternode's operator identity gets a TRANSFER key (ECDSA_HASH160of the operator payout address), and that key signs credit withdrawals from the identity. Up to protocol version 14 the payout handling was broken in two ways:update_operator_identityv0 still gave the new operator identity a TRANSFER key from an existing key or from the stored payout, both of which belong to the earlier operator.On mainnet, from the repo fixture at Platform genesis and today's public
masternodelist:No user has lost anything yet. An operator identity receives credits only through the owner's
rewardSharedocuments, and the public explorer shows 0 such documents on mainnet and 0 on testnet. The wrong keys guard empty balances today.Both items change identity keys in GroveDB, so the fix starts at protocol version 15 (unreleased: testnet runs 14, mainnet 13). Protocol versions 1 to 14 replay exactly as before.
What was done?
Everything below is selected only by protocol version 15's table (

Only the answer'sstateis decoded. rust-dashcore's typedProTxInforeadsoperatorRewardas an integer, while Core prints a decimal (13.37 and 2.5 on mainnet), and itsmetaInfoholds node-local numbers. The hash is sent in Core's form (to_string;to_hexis byte-reversed). drive-abci refuses to start when Core refusesprotx info(HTTP 403), like itsgetspecialtxesstartup check. Core empties the payout on every key change and prints nothing for the clear. It also prints a payout only when it differs between the diff's two heights, so an entry without one cannot tell "cleared" from "set again to the same payout" (rotate and restore inside onecrange). Only such entries trigger the call: about one per operator key change, and mainnet has had 31 since Platform's genesis. A Core error fails the block. A payout printed in the diff is used as is.fetch_core_fork_activation_height) instead of a Core call. The list update runs insideupdate_core_infov1, after the record step at the samec, and only in blocks that movec, so the record gives the same answer Core would.DMNState::apply_diff, which keeps a revived height the diff does not print.update_operator_identity1:IdentityKeyAlreadyExistson every node and halts the chain. Step 5 of the spec's earlier draft, a filter for re-sent payouts, is therefore not needed and was dropped. Keeping it would also stop a re-sent payout from healing an identity's keys.IdentityKeyAlreadyExists.Drive
add_new_keys_to_masternode_identity1 (new slot: 0 in every shippedDRIVE_VERSION, 1 inDRIVE_VERSION_V10, which only PV15 selects): a masternode key whose hash the identity already holds a non-unique key-hash reference for, or that an earlier key of the same call has, is added without a second reference. Each key keeps its own id and purpose. User identity updates keepadd_new_keys_to_identityand are unaffected.Drive
apply_drive_operations2 (PV15-only, amended in place): after a batch is lowered, it keeps the first of the identical inserts that create a hash's tree under the non-unique key hashes tree. Each identity operation is lowered against stored state, so several identities adding a key of one new hash in one batch each queue that tree; masternodes whose operators share a payout address do this in the reconciliation. A batch checked for consistency (batching_consistency_verification) refused the repeats. The unchecked default kept the last of the identical inserts, so default nodes write the same state either way.One-time reconciliation in the first block of protocol version 15 (
transition_to_version_15→reconcile_operator_payouts_with_core):protx listdiff 1 c_prev) at the last committed chain-locked core heightc_prev, the height Platform's list is at when the upgrade hook runs. The block's own diffc_prev → cis applied afterwards, under the new rules.update_operator_identity1 with Core's payout. That reconciles all of its TRANSFER keys and changes nothing where they already match. The stored payout alone does not tell which identities need it: up to PV14 a platform node id matched keys by data alone, so an evonode whose node id once had its payout's bytes can have its payout key disabled while the stored payout and Core's agree.Why read Core in the upgrade block here, when
core-fork-activations.mdavoids it for the fork probe:c_previs chain locked and an earlier block already read Core at it, so every validator's Core holds that block and reports the same list.c.Why
c_prevand not the proposal'sc: the hook runs beforeupdate_core_infoapplies this block's diff. Reconciling thec_prevlist against Core's list atcwould compare two different lists.

Red → green (each fix's tests run first against the code without it):
operator_payout_tests, against the unfixed tree: all 5 fail. The payout key is not added, the new operator inherits P0, a retired identity keeps P0, and the revived height is cleared.With list v2 but
update_operator_identitystill 0, the re-sent payout test fails withIdentityKeyAlreadyExists: the chain halt.With
update_operator_identity1, all pass.With the reconciliation call removed from
transition_to_version_15, the 13→15 and 14→15 upgrade test fails: no Core read, stale keys kept. With it, it passes.The hash-collision regression tests fail against v1 as first committed. The payout-equals-node-id case fails with "key to disable with specified ID is not found", which is the chain halt the review reproduced. The new-identity case keeps a duplicate-hash node-id key. Both pass with the fix.
After the bot review, three tests fail against the previous fix:
9f9f…), and the previous fix left keys out;With the ABCI guard removed but
DRIVE_VERSION_V10still selecting Drive v0, the collision test fails withIdentityKeyAlreadyExists. With Drive v1 and the reconciliation covering every masternode, all three pass.With Drive v1's same-call de-duplication disabled,
should_add_two_keys_with_one_hash_in_one_callfails with "insertion order error" (a duplicate operation in a consistency-checked batch). Restored, it passes.With the new parent-tree de-duplication in
apply_drive_operations2 removed, the Drive and upgrade-block shared-hash tests fail with "insertion order error" under consistency checks. With it, they pass, and protocol 14 still refuses the checked batch, as before.Rotate and restore (F2):
should_take_the_payout_core_reports_for_an_operator_key_change_printed_without_onecovers a new identity and a returning identity with the payout restored inside one Core height range, and a reset. It also asserts that Core is asked only about those entries. It fails before (the new identity gets no payout key) and passes with the Core read.The new Core read: with
ProTxHash::to_hexin the request,should_ask_protx_info_for_the_masternode_at_the_block_of_the_height(a real JSON-RPC connection) fails, because Core receives the reversed hash. With Core's form it passes. The same test reads an answer with"operatorReward": 13.37, which rust-dashcore's typed answer cannot read; the reviewer reproduced that failure against mainnet Core.New tests:
update_core_info(recorded earlier, in this block, not active; Core is asked only by the record step).add_new_keys_to_masternode_identity(consistency checks on): a hash the identity already references (fails at 14, added from 15), two keys with one hash in one call, a unique-key hash (no reference at 14 and 15).update_operator_identity1 selects Driveadd_new_keys_to_masternode_identity1 or later.The six operator-key-encoding scenarios now also run at 15, with V24 recorded the way
update_core_info1 records it. The latest() tests that assert the old semantics run at 13 and 14. The mainnet fixture tests (test_update_masternode_list,should_build_the_validators_earlier_binaries_built_from_mainnet_masternode_lists) pass at 13 and at latest.Ran locally:
cargo test -p drive-abci --lib: 4554 passed, 17 ignored, after the F2 fix (before the merge of v5.1-dev's latest three commits; after it,core_based_updates,protocol_upgrade,identity_createand the shield nullifier tests pass, 495). Earlier: 4536 passed, 17 ignored, and 2 failed. The 2 failures were two shield tests that upgrade from 13 and needed a Core answer. I fixed them after that run's binary was built, and a re-run of those two pluscore_based_updatesandprotocol_upgradepassed (227).

Its must-fixes are folded in: the hash-collision chain halt, a stale book paragraph, broken shield tests, and missing tests.
Breaking Changes
Consensus change at protocol version 15: operator payouts follow Core's diffs, an operator key change printed without a payout reads the payout from Core (
protx info, which needs the dashmate whitelist migration), operator identities' TRANSFER keys are reconciled with them, and the first block of protocol version 15 reads Core's full masternode list. The Rust signature ofperform_events_on_first_block_of_protocol_changegains a parameter and aCoreRPCLikebound. Protocol versions 1 to 14 are unchanged.Out of scope
protx listdiff(pre-existing, spec F3). The next printed payout heals it.Open items
protx listdiff 1 h, and check four things: membership, that every entry parses, the correction count, and that every current operator identity exists (all of them are now reconciled, and a missing one fails the block). Also time the identity work. A membership mismatch or a parse error fails the upgrade block on every node, and the masternode list is outside the app hash, so a past divergence would not have shown.get_protx_infosendsProTxHash::to_hex()(byte-reversed against Core's form), and itsProTxInforeadsoperatorRewardas an integer, while Core prints a decimal. Drive callsprotx infodirectly and reads onlystate; with those fixed upstream it could use the typed client again.protx listdiffthat prints the final operator payout whenever it prints an operator-key change, including unchanged payouts and explicit clears, would make theprotx inforead unnecessary at a later protocol version.ECDSA_HASH160key nobody can sign, and an evonode reset leaves a zero platform node id key (Q6). Neither affects balances.Checklist:
