Wildfire

Wildfire Release

Activation Height 1,003,000 👈

Cross-chain atomic swaps, privacy hardening, lower minimum fee, dust threshold lowered, and a broad security pass.

ЅШ𑫛𑫒❋XFG Atomic Swaps

Supported Chains

Chain	Adapter	Keying
Bitcoin Cash	BchChainClient	secp256k1
Ethereum ( L2s: Arbitrum & Base)	EthChainClient	EIP-155 secp256k1 offline signing + eth_sendRawTransaction
Monero	XmrChainClient	Ed25519 reserve-proof verification
Solana	SolChainClient	Ed25519 + base58

• Polymorphic ChainRegistry dispatches all swap pairs through a plugin IChainClient interface
• Cross-chain timelock-ordering safety (SwapTimelock) across all supported pairs

AFK Auto-Execution Engine

• Soft-order auto-execution via OfferManager — griefing protection with taker rate-limiting, partial fills, price-drift auto-cancel
• Headless daemon mode (--service) with loopback JSON status endpoint (StatusServer)
• Taker P2P swap-request relay

---

Fire aliases

• Human-readable ie@fuegoxfg 8 character-only addresses registered on-chain
• Registration fee: 1 XFG (+random dust for privacy) sent to Fuego Development Fund @fuegodev
• One-time sub-address used for alias registration
• Ring-signature mixin applied to alias registration transactions
• Standard individual aliases only at this time

---

Privacy & Security

Dynamic Ring Sizes (DynaMaxin / OSPEAD)

• Minimum mixin 2 → 8; max remains 32
• Dynamic ring size buckets: {32, 16, 8} — selected based on output pool depth
• OSPEAD logarithmic age-bin sampling — decoy spend-probability filter wired into tx build path
• Mixin upper bound gated behind keeped_by_block for sync-era compatibility

Dandelion++ Network Privacy

• Stem-fluff transaction relay — per-hop coin-flip (90% stay, max 10 hops)
• Swap offers relayed via Dandelion++ (separate stem path: 80% stay, max 5 hops)
• Embargo timer: 30s; epoch rotation: 90s
• Relay constants extracted to config

Swap Security

• Adaptor-secret at-rest encryption: CryptoNight-KDF + ChaCha8 + HMAC-SHA256; derived from wallet key, never persisted
• Ed25519 authentication on all swap P2P messages
• Small-subgroup point rejection in adaptor/DLEQ verifiers
• RPC error responses sanitized

Wallet & P2P Hardening

• Wallet container integrity upgraded to HMAC-SHA256 (v7); wallet files set to 0600
• MLSAG nonce zeroing on all paths; RNG fork-safety; modulo-bias elimination
• Mempool DoS hardening: tx size 4MB cap, extra 4KB cap, 800MB pool limit
• P2P: Levin max packet size 1MB→100MB

Consensus Changes

Difficulty Algorithm

	v9	v10
Algorithm	LWMA (N=60)	LWMA-1 (N=36)
Function	nextDifficultyV5()	nextDifficultyV6()
Solvetime clamp	T/2 – 8T	T/3 – 6T
Rounding	Standard	Clean number rounding

Penalty Formula Bugfix

64-bit safe intermediate multiplication — prevents overflow on ARM/32-bit. Pre-v10 formula preserved for historical blocks.

Parameter	v9	v10
Transaction fee	0.008 XFG	0.0008 XFG (10× reduction)
Dust threshold	0.002 XFG	0.0001 XFG

Coinbase validation	Lax	Strict exact-match

Infrastructure

• IndexManager delegates blockchain indices; async rebuildCache with lock gate
• ARM hardware AES on Apple Silicon
• arm64 Homebrew prefix detection for jsoncpp
• Docs: SPV light-client ADR, swap expansion guide
