Spam filter configuration

Fields

filter_ordinals: bool

Filter Ordinals/Inscriptions

filter_dust: bool

Filter dust outputs

filter_brc20: bool

Filter BRC-20 patterns

filter_large_witness: bool

Filter transactions with large witness data

filter_low_fee_rate: bool

Filter transactions with low fee rate

filter_high_size_value_ratio: bool

Filter transactions with high size-to-value ratio

filter_many_small_outputs: bool

Filter transactions with many small outputs

dust_threshold: i64

Minimum output value to consider non-dust (satoshis)

min_output_value: i64

Minimum output value to include in filtered blocks (satoshis)

min_fee_rate: u64

Minimum fee rate threshold (satoshis per vbyte)

max_witness_size: usize

Maximum witness size before flagging (bytes) Note: This is now adaptive based on script type when use_adaptive_thresholds is enabled

max_size_value_ratio: f64

Maximum size-to-value ratio (bytes per satoshi)

max_small_outputs: usize

Maximum number of small outputs before flagging

use_adaptive_thresholds: bool

Use adaptive witness size thresholds based on script type Default: true (enables data-driven thresholds)

adaptive_thresholds: WitnessSizeThresholds

Adaptive threshold configuration

filter_taproot_spam: bool

Filter Taproot-specific spam patterns (control blocks, annexes) Default: true

max_taproot_control_size: usize

Maximum Taproot control block size (bytes) Control blocks: 33 bytes base + 32 bytes per tree level BIP-110 limits to 257 bytes (depth 7), we use 289 bytes (depth 8) for policy Default: 289 bytes (allows depth 8, more lenient than BIP-110)

reject_taproot_annexes: bool

Reject Taproot annexes (last witness element starting with OP_RESERVED) Default: true

filter_large_total_witness: bool

Filter transactions with large total witness size across all inputs Default: false (disabled by default, can be aggressive)

max_total_witness_size: usize

Maximum total witness size across all inputs (bytes) Default: 5000 bytes

use_improved_envelope_detection: bool

Use improved envelope protocol detection (checks for OP_ENDIF) Default: true

use_json_validation_brc20: bool

Use JSON validation for BRC-20 detection (requires serde_json) Default: true (if serde_json available)

require_utxo_for_fee_rate: bool

Require UTXO set for fee rate calculation (reject if unavailable) If false, falls back to heuristic when UTXO set unavailable Default: false (use heuristic fallback)

min_fee_rate_large_tx: u64

Minimum fee rate for large transactions (satoshis per vbyte) Transactions larger than large_tx_threshold_bytes require this fee rate Default: 2 sat/vB (higher than standard 1 sat/vB)

large_tx_threshold_bytes: usize

Large transaction threshold (bytes) Transactions larger than this require min_fee_rate_large_tx Default: 1000 bytes

ordinals_strict_mode: bool

Ordinals detection mode: strict (envelope/pattern only) vs legacy (includes large witness heuristics) When true: Ordinals = envelope protocol, ordinal output patterns, Taproot annex/control-block. Large witness alone is NOT Ordinals (handled by LargeWitness category). When false: Legacy behavior - large witness and witness data patterns also trigger Ordinals. Default: true (minimize false positives; Miniscript/vaults no longer misclassified as Ordinals)
