fix(dash)!: restore the serde formats of `PlatformNodeId`, `BLSPublicKey` and pre-v4 `CoinbasePayload` by ZocoLini · Pull Request #1149 · dashpay/rust-dashcore

ZocoLini · 2026-10-09T13:48:18Z

Restores the serde formats Platform persists (bincode::serde blobs in its wallet storage), changed since its pinned revision 40268cc0.

PlatformNodeId: back to its own type, stored in canonical order. The EddsaPkHash alias serialized the bytes reversed.
BLSPublicKey: back to a type serialized as a hex string. Delegating to the dash-pkc bytes type wrote raw bytes. Crypto ops convert to and from BlsPkBytes.
CoinbasePayload: hand-written serde keeping the 7-field shape before version 4. merkle_root_asset_unlocks is only written and accepted from version 4.

Tests pin the binary serde bytes of PlatformNodeId and BLSPublicKey, and check that the pre-v4 CbTx shape decodes.

Breaking: PlatformNodeId and BLSPublicKey are no longer aliases of the dashcore-crypto types.

Summary by CodeRabbit

Compatibility
- Coinbase payloads now preserve the expected serialized format across versions, including support for the additional version 4 field. Older payloads remain compatible, while that field is rejected in pre-version-4 JSON.
- Platform node IDs and BLS public keys now have consistent byte and serialization handling across wallet and transaction operations.
Bug Fixes
- Improved aggregate signature verification to handle operator public keys using their respective legacy or modern encodings.

…ation #1056 replaced `PlatformNodeId` with an alias of `EddsaPkHash`, which holds the wire order. Its binary serde writes the in-memory bytes, so `bincode::serde` started storing node IDs byte-reversed, silently misreading records persisted before (Platform stores wallet transaction records this way). Restore the earlier `PlatformNodeId`, which holds the canonical order and reverses only on the consensus wire, so JSON, binary serde, native bincode and consensus encodings match the pre-#1056 ones again, as do `from_byte_array`/`to_byte_array`. `EddsaPkHash` stays as the Ed25519 public key hash and converts into a `PlatformNodeId` in canonical order. A test pins the binary serde bytes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

#1137 added `merkle_root_asset_unlocks` to the derived serde impl, which writes it for every version, so coinbase payloads persisted through binary serde before (Platform stores wallet transaction records this way) no longer decode. Write the serde impls by hand with the earlier shape, adding the field only from version 4, as the bincode impl already does. Tests check that a version 3 payload serializes to the same bytes and JSON as the earlier derived impl and decodes from them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

#1036 made `BLSPublicKey` an alias of `BlsPkBytes`, whose serde impl writes raw bytes in binary formats, while the earlier type wrote its hex string in every format. Records persisted through binary serde before (Platform stores wallet transaction records this way, with operator keys in ProRegTx and ProUpRegTx payloads) no longer decode. `BLSPublicKey` is its own 48-byte type again, serialized as a hex string in every format as before. Native bincode and the consensus encoding are unchanged. It converts to and from `BlsPkBytes` for cryptographic operations, which the quorum aggregate verification and the key-wallet BLS derivation now do explicitly. A test pins the binary serde bytes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…de maps The hand-written `visit_map` accepted `merkle_root_asset_unlocks` at any version, so a version 3 map carrying it decoded into a payload whose root was dropped on the next encode. Read the version first and reject the field before version 4, as `visit_seq` already ignores it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

📝 Walkthrough

Walkthrough

The changes add version-aware Serde behavior for coinbase payloads, introduce dedicated PlatformNodeId and BLSPublicKey types, and update wallet, FFI, and quorum code to use the updated types and byte representations.

Changes

Coinbase payload Serde

Layer / File(s)	Summary
Version-aware fields and compatibility tests `dash/src/blockdata/transaction/special_transaction/coinbase.rs`	Custom Serde implementations include `merkle_root_asset_unlocks` for version 4 or later. Tests cover version-3 compatibility, version-4 round trips, and rejection of the field in version-3 JSON.

Platform node ID

Layer / File(s)	Summary
Platform node ID representation and encoding `dash/src/lib.rs`, `dash/src/platform_node_id.rs`	`PlatformNodeId` stores canonical-order bytes and adds byte-array access, Ed25519 key derivation, conversion from `EddsaPkHash`, and consensus encoding that reverses bytes for the wire format. Tests cover encoding, conversions, and serialization compatibility.
Platform node ID payload and wallet call sites `dash/src/blockdata/transaction/special_transaction/provider_`, `key-wallet-ffi/src/special_payload.rs`, `key-wallet/src/transaction_checking/account_checker.rs`, `key-wallet/src/tests/`, `key-wallet/src/transaction_checking/transaction_router/tests/provider.rs`	FFI serialization and wallet matching use byte-array accessors. Related tests use the new constructor.

BLS public key

Layer / File(s)	Summary
BLS public key wrapper and serialization `dash/src/bls_sig_utils.rs`	`BLSPublicKey` replaces the `BlsPkBytes` alias with a 48-byte wrapper. It adds byte conversions, hex formatting and parsing, zero checks, and Serde support. Tests cover serialization and conversions.
Wallet key conversions and aggregate verification `key-wallet/src/account/bls_account.rs`, `key-wallet/src/derivation_bls_bip32.rs`, `key-wallet/src/managed_account/managed_account_trait.rs`, `dash/src/sml/quorum_entry/validation.rs`	Wallet key creation and decoding convert canonicalized keys to `BLSPublicKey`. Aggregate verification collects operator key bytes and passes references to the collected keys.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Suggested reviewers: kwvg

Merge Risk: 🔵 Low · up to 8fe0a

Serde map input for coinbase payloads is slightly more permissive than before and can silently pick the last duplicate value or drop a null field. Tightening the map parsing is a small fix and is worth doing before or shortly after merge.

- Line 158: Update the coinbase transaction deserialization logic around
`merkle_root_asset_unlocks` to track whether the field appeared independently of
its parsed `Option` value, and reject any occurrence when `version` is below 4,
including explicit JSON null. Add a test confirming that a version-3 map with
this field set to null is rejected.
- Line 138: Update the custom map deserializer for the coinbase transaction so
each recognized field rejects a second occurrence before calling
map.next_value(). Track field presence separately from stored values for
nullable fields, ensuring a first null still counts as seen.
