This change enables compact block filters (BIP157) functionality by default: - Sets DEFAULT_BLOCKFILTERINDEX to "basic" instead of "0" - Sets DEFAULT_PEERBLOCKFILTERS to true instead of false This improves privacy for light clients and enables better pruned node support.
Documents the change to enable BIP157 block filters by default.
Updates the release notes file name and PR reference from 6708 to 6711.
When blockfilterindex defaults to "basic" but no explicit command line
argument is provided, GetArgs("-blockfilterindex") returns an empty vector.
This caused the validation logic to fail with "Cannot set -peerblockfilters
without -blockfilterindex" error.
Add check for empty names vector and use the default value when needed.
Three tests needed updates to work with the new defaults where -blockfilterindex=basic and -peerblockfilters=true: - p2p_blockfilters.py: Explicitly disable peerblockfilters for node 1 which doesn't serve compact filters - rpc_getblockfilter.py: Explicitly disable both options for nodes that should not have block filter index - rpc_misc.py: Explicitly disable both options when testing the absence of indices 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
…faults Node 1 was configured with only -coinstatsindex=1, but with the new defaults it was also getting -blockfilterindex=basic enabled. The test expects node 1 to only have coinstatsindex, so we need to explicitly disable blockfilterindex and peerblockfilters. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
When BIP157 filters are enabled by default, the restart_without_indices function needs to explicitly disable both blockfilterindex and coinstatsindex to avoid conflicts with pruning.
With peerblockfilters now enabled by default, the test must explicitly disable it when disabling blockfilterindex to avoid initialization errors. Co-Authored-By: Claude <noreply@anthropic.com>

Firstly, production code (even in debug mode) should not operate as unit test by calling heavy GetMN
just to be sure that implementation is not broken.
Secondly, since mn_rr hard-fork is activated it doesn't affect any new blocks; but it is used for
validation of old blocks only.
Thirdly, it removes useless log record (especially now when no more 4x payments for Evo Nodes).

Firstly, it's easier to spot changes in mocktime and calculate how long if time is logged in seconds. Secondly, the start time `2014-12-04T17:15:37Z` (genesis block) is not round number which makes calculation of "how much exactly time pass" even more difficult.

Should help debugging when you have a payment with a correct address but with an invalid amount.
Random session ids make it much easier to debug comparing to monotonously increasing ones and also you don't have to track the next id in this case.

⚙️ CodeRabbit Configuration File
**: # CodeRabbit AI Review Instructions for Dash BackportsYour Role
You are reviewing Bitcoin Core backports to Dash Core. Your ONLY job is to validate that the Dash commit faithfully represents the original Bitcoin commit with minimal, necessary adaptations.
Critical Validation Rules
1. File Operations Must Match (AUTO-REJECT if violated)
- If Bitcoin modifies an existing file → Dash MUST modify (not create new)
- If Bitcoin creates a new file → Dash creates
- If Bitcoin deletes a file → Dash deletes
- Common failure: Bitcoin modifies keys.txt, Dash creates new file with 58 keys
2. Size Ratio Check (80-150% of Bitcoin)
- Count functional lines changed (exclude comments/whitespace)
- Dash changes should be 80-150% of Bitcoin's size
- Red flag: 2-line Bitcoin fix becoming 150+ lines in Dash
3. No Scope Creep
- Reject if you see: "TODO:", "FIXME:", "while we're here", "also fix"
- No unrelated refactoring or style changes
- Only Bitcoin's intended changes + minimal Dash adaptations
4. Bitcoin-Specific Code Detection
- Auto-reject witness/segwit code:
msg_wtxidrelay,MSG_WTX, witness imports- Auto-reject RBF (replace-by-fee) functionality
- Note: PSBT is supported in Dash (don't flag)
5. Mandatory Adaptations Only
bitcoin→dashin strings/pathsBitcoin→Dashin user-facing text- Port numbers: 8332→9998 (RPC), 8333→9999 (P2P)
- Hardcoded test values specific to Dash
- No other changes unless absolutely required
6. Completeness Check
- All files changed in Bitcoin must be present
- Extra files need clear justification (Dash-specific compatibility)
- Missing files = incomplete backport
Review Process
- First: Check file operations match exactly
- Second: Calculate size ratio
- Third: Scan for scope creep patterns
- Fourth: Detect Bitcoin-specific code
- Fifth: Verify all changes are minimal adaptations

Learning: During multiple verification attempts of Bitcoin Core commit 06d469c26b backport to Dash PR #566, DashCoreAutoGuix consistently identified scope creep in interface_usdt_utxocache.py where additional pruning test functionality was added beyond the original Bitcoin commit. The user provided comprehensive fixes including both scope creep removal and missing mempool test file additions, but couldn't push due to authentication restrictions. The scope creep fix was identified as the priority to resolve CI failures.

Learning: In Dash backports from Bitcoin Core, including necessary compilation fixes (such as API compatibility changes like UniValue get_int() → getInt<int>()) alongside the core backport is standard and expected practice. These compatibility fixes ensure the backported code compiles in Dash's evolved codebase while preserving Bitcoin's original functionality and intent.

59-109: Parameter validation improvements look correct.The enhanced input validation for
GetNetworkHashPSfollows Bitcoin Core patterns and correctly validates bothlookupandheightparameters. The logic changes are minimal and appropriate for the backport.

🧩 Analysis chain
Comprehensive test coverage for enhanced parameter validation.
The new test cases thoroughly validate all the enhanced parameter checking introduced in the mining RPC code. However, there's a missing constant definition issue.
Missing DIFFICULTY_ADJUSTMENT_INTERVAL constant:
The test uses DIFFICULTY_ADJUSTMENT_INTERVAL on line 473, but this constant is undefined. According to Dash backport practices, this should be defined as 24 for Dash (different from Bitcoin's value).
You'll need to add this constant definition at the top of the test file:
DIFFICULTY_ADJUSTMENT_INTERVAL = 24 # Dash specific value🏁 Script executed:
#!/bin/bash
# Search for DIFFICULTY_ADJUSTMENT_INTERVAL definition in the codebase
rg "DIFFICULTY_ADJUSTMENT_INTERVAL" --type pyLength of output: 177
🏁 Script executed:
#!/bin/bash
# Check if textwrap is imported in rpc_blockchain.py
rg "^import textwrap" test/functional/rpc_blockchain.pyLength of output: 73
Define DIFFICULTY_ADJUSTMENT_INTERVAL in rpc_blockchain.py
The test refers to DIFFICULTY_ADJUSTMENT_INTERVAL but it isn’t defined in this file. Add the Dash-specific value at the top of test/functional/rpc_blockchain.py, for example right after the imports:
import textwrap
+DIFFICULTY_ADJUSTMENT_INTERVAL = 24 # Dash-specific difficulty adjustment intervalThis will ensure:
- The modulo calculation on line 473 works correctly.
- Consistency with other Dash backported tests that expect a 24-block interval.

Previously, only bloom filters could detect special transaction fields, leaving compact block filter users unable to track masternode-related transactions and platform operations. ### Implementation Details The implementation uses a delegation pattern to extract special transaction fields without creating circular dependencies: - `ExtractSpecialTxFilterElements()` function extracts relevant fields from each special transaction type - Fields extracted match exactly those in the bloom filter implementation (`CheckSpecialTransactionMatchesAndUpdate`) - All 5 special transaction types are supported: - **ProRegTx**: collateral outpoint, owner/voting keys, payout script - **ProUpServTx**: ProTx hash, operator payout script - **ProUpRegTx**: ProTx hash, voting key, payout script - **ProUpRevTx**: ProTx hash - **AssetLockTx**: credit output scripts (excluding OP_RETURN) ### Testing Comprehensive test coverage includes: - **Unit tests**: Test all 5 special transaction types with realistic payloads - **Functional tests**: Create actual AssetLockTx transactions with proper signatures - **Edge cases**: Empty scripts, OP_RETURN exclusion, multiple outputs ## Test plan - [x] Unit tests pass (`make check`) - [x] Functional test passes (`test/functional/p2p_blockfilters.py`) - [x] All special transaction types covered in tests - [x] Verified special fields are added to filters (via debug logging) 🤖 Generated with [Claude Code](https://claude.ai/code) ACKs for top commit: knst: utACK 4b90441 UdjinM6: utACK 4b90441 Tree-SHA512: 673b47ef8626761cdffc659c6ca0ffd214b6d3e7ea6086976528ec79967f5a6a6d864b63cc1e5bac38f079fa092c49637f334c058231b4f6c687f9dae585db27
