Basic explanation

What this does: Retires old on-disk Platform state and quorum formats in v5.1.0. Loading one returns a migration instruction instead of decoding it.

Value: Removes the C++ bls-signatures dependency from the default production node. Tests and explicit mocks builds still use it.

Risks: This intentionally prevents direct startup from older databases and snapshots. Operators must run Platform v4.0.0 on the database and successfully commit at least one block before upgrading. The complete upgrade path has not been tested.

Issue being fixed or feature implemented

Targets v5.1-dev, which includes the BLS backend migration from #5320 and retains historical storage support. This PR isolates the compatibility-policy decision from that migration.

Production uses of the separate C++ BLS crate are in old storage readers. v4.0.0 writes Platform-state V1 and quorum-storage V2, while still being able to read older records.

What was done?

• Remove the Platform-state V0 and quorum-storage V0/V1 readers and conversions. Each retired generation keeps its file at its historical path, with a header saying why the reader was removed, the version, and this PR.
• Each of those generations is now an uninhabited placeholder holding its enum position. Its decoder immediately returns one shared error directing the operator to v4.0.0; it does not parse the old payload or panic. old_structures had no entry point of its own, so it stays as a comment-only module.
• Preserve Platform-state V1/V2 and quorum-storage V2 tags, layouts and serialized bytes.
• Remove bls-signatures from default features; retain it for tests and the explicit mocks feature.
• Test rejection of old testnet/devnet records and owned/borrowed quorum decoding. Keep a supported-format fixture serialized before reader removal and check the existing serialization hash.

In-place changes to shipped generations

This changes local database compatibility, not block execution rules. Serialization already writes supported formats for all protocol versions. The rejection applies when loading old records, including outer Platform-state V0 records; no version table or protocol activation changes are introduced.

How Has This Been Tested?

• cargo test -p drive-abci --lib --all-features --locked platform_types: 133 tests, covering legacy errors, preserved supported tags and byte round trips.
• cargo clippy -p drive-abci --all-targets --all-features --locked -- --no-deps -D warnings.
• cargo clippy -p drive-abci --lib --locked -- --no-deps -D warnings verifies the default production configuration.
• Historical quorum fixtures retain coverage of supported V2 records and fixed 48-byte key encoding; V0 and V1 fixtures assert the intended upgrade error.
• Formatting and whitespace checks.
• The normal/build dependency tree for default drive-abci excludes bls-signatures and bls-dash-sys.

No full replay or end-to-end v1.0 → v4.0.0 → this branch upgrade was run. Tests prove decoder behavior and supported serialization compatibility, not the complete operational migration procedure.

Breaking Changes

Direct loading of Platform-state V0 and quorum-storage V0/V1 databases/snapshots becomes unsupported. Operators must first have v4.0.0 successfully commit a block on that database; merely launching the binary is insufficient.

The title omits ! because the repository reserves it for consensus-breaking changes.

Walkthrough

The PR replaces bls-signatures with workspace dashcore-crypto, rejects decoding of retired platform-state V0 and quorum V0/V1 records, and updates quorum test key generation and compatibility checks.

Changes: Legacy BLS storage and quorum updates

Update BLS and GMP build requirements .github/SELF_HOSTED_RUNNER.md, .github/actions/npm-release-build/action.yaml, .github/workflows/*, packages/rs-drive-abci/Cargo.toml	The crate uses workspace dashcore-crypto with its bls feature instead of bls-signatures.

The legacy-format rejection is supported by compatibility tests and the v4.0.0 serialization path. Merge risk is bounded to incomplete historical-V2 and end-to-end upgrade coverage; these improvements can be tracked as follow-up.

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

The retired-format decoders preserve supported storage tags and keep compatibility policy in drive-abci, but two storage-fetch tests still require retired fixtures to load successfully. Current-head CI confirms both failures in “Rust workspace tests / Tests,” making this a blocking test regression. The documented v4.0.0 recovery path also retains a nonblocking migration-coverage gap; verification was static, with no local builds or tests.

- [BLOCKING] packages/rs-drive-abci/src/platform_types/platform_state/platform_state_for_saving/v0/mod.rs:27-29: Update storage-fetch tests that still require retired formats
  The rejection is intentional, but `execution/storage/fetch_platform_state/mod.rs::fixtures()` still supplies `PLATFORM_STATE_V3_TESTNET` and `PLATFORM_STATE_V8_DEVNET` to success-path tests. `should_save_historical_platform_states_with_unchanged_bytes` now panics while decoding at line 110, and `should_refuse_to_restore_saved_state_holding_zero_chain_lock_active_signers_or_window` panics on its valid `(1, 1)` control at line 146, before exercising the zero-value checks. The current-head Rust workspace CI log confirms both failures with this migration error: https://github.com/dashpay/platform/actions/runs/41866792234/job/126703756350. Update these consumers to use supported-format fixtures for successful byte round trips and configuration validation through both fetch generations, and retain retired fixtures as explicit rejection cases. This requires updating the tests, not restoring the retired production readers.

- [SUGGESTION] packages/rs-drive-abci/src/platform_types/platform_state/mod.rs:367-375: Cover the required v4.0.0 migration boundary
  (existing thread: https://github.com/dashpay/platform/pull/5323#discussion_r4455711351)
  Mainnet running v5.0 narrows this to recovery of preserved older databases, rather than the normal upgrade path for current validators. The decoder nevertheless directs affected operators through v4.0.0, while the tests cover legacy rejection and already-supported records: the replacement devnet fixture was reserialized at `734bd4eea7`, and the historical vector generator pins `6499c680c6bc311e8933f396423a79459e2a88bd`. Neither exercises the prescribed v4.0.0 commit-and-reload boundary. Inspection of the v4.0.0 source supports the instruction—it reads the retired formats, writes Platform-state V1 with quorum V2, and persists state during block finalization—but does not replace that regression coverage. Add a reproducibly generated fixture or bounded cross-release test that loads populated legacy state in pinned v4.0.0, commits a block, and reloads through the current `fetch_platform_state` dispatcher, checking validator membership, current and previous quorum contents, and the expected committed root. This remains nonblocking recovery coverage; if deferred, link a tracking issue for that specific test.

Checked whether this is needed for replay. PlatformStateForSaving V0 did use the C++ crate, but nothing has written that format since v1.4, and nothing has written quorum V0/V1 since v2.0. The writers don't depend on protocol version, and the state lives in aux storage outside the app hash, so a replay from genesis never touches the old readers. Only a DB last written by v1.8 or older breaks, and the error message covers that.

Fine by me once the two fetch_platform_state tests stop using the retired fixtures (Rust CI is red on them):

• should_save_historical_platform_states_with_unchanged_bytes
• should_refuse_to_restore_saved_state_holding_zero_chain_lock_active_signers_or_window

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

Static verification of head 50c2487 confirms that the storage-fetch fixture regression is addressed, supported serialization layouts remain intact, and upstream recovery ownership and GMP image requirements are accounted for. One non-blocking suggestion remains: exercise the v4.0.0 commit-and-reload recovery procedure prescribed for retired databases. No builds or tests were run; current CI shows policy/reconcile passing, review and hygiene pending, and no Rust build or test result.
