Crypto Backend Refactoring
──────────────────────────
- Delete src/ed25519.js — all scalar/point operations now route through
the crypto provider (WASM/FFI/JSI backends only)
- Remove duplicate JS BigInt implementations of scReduce32, scReduce64,
scalarAdd, scalarMul from scanning.js, carrot.js, and carrot-scanning.js;
delegate to Rust backend via crypto/index.js
- Remove debug/test exports from index.js (randomPoint, testDouble,
getBasePoint, isOnCurve, etc.) that were only used during development
- Rebuild WASM binary (476KB → 487KB) with updated Rust crate
Consolidated CryptoNote Scanner (cn_scan)
─────────────────────────────────────────
- New Rust module crates/salvium-crypto/src/cn_scan.rs replaces 5-12
individual FFI round-trips per output with a single native call:
view tag check → derive subaddress pubkey → subaddress map lookup →
amount decryption → commitment mask → key image generation
- FFI wrapper salvium_cn_scan_output in ffi.rs + C header declaration
- FFI backend scanCnOutput() with full subaddress map marshaling
(32-byte key + u32 major/minor LE per entry) and JSON result parsing
- JSI backend delegation via this.native.cnScanOutput()
- wallet-sync.js _scanCNOutput() tries native path first when available
(FFI/JSI), falls through to existing JS pipeline for WASM/JS backends
- Change pub(crate) visibility on subaddress.rs cn_subaddress_secret_key
- 8 Rust unit tests covering view tag, amount, commitment mask,
subaddress matching, and key image generation
- Verified identical results: WASM (JS fallback) and FFI (native cn_scan)
produce same 964 outputs at same chain height; FFI is 3x faster sync
(0.8s vs 2.5s) with 12x less heap (12MB vs 150MB)
RCT Batch Signature Verification
─────────────────────────────────
- New Rust module crates/salvium-crypto/src/rct_verify.rs — single-call
verification of all ring signatures in a transaction (CLSAG + TCLSAG),
avoiding N individual JS↔Rust boundary crossings
- Computes pre-MLSAG message hash matching C++ get_pre_mlsag_hash
- FFI export salvium_verify_rct_signatures with flat byte array interface
- FFI backend verifyRctSignatures() method
- JS backend stub returns null (validation.js handles JS fallback)
- validation.js: 200+ lines of RCT verification logic including
flattenKeyImages, packTclsagSigsFlat, packClsagSigsFlat helpers
Transaction Expansion
─────────────────────
- transaction.js: add expandTransaction() matching C++ expand_transaction_2
(copies key images from prefix inputs into TCLSAG/CLSAG signature structs)
- New test/expand-transaction.test.js (634 lines)
- New test/rct-verify-testnet.test.js (430 lines)
Mining Resilience
─────────────────
- salvium-miner main.rs: retry get_info and get_block_template up to 5
times with 2s delay for transient daemon errors
- full-testnet.js mineTo(): retry miner up to 3 times with 3s delay,
check for partial progress between attempts
Testnet Tooling
───────────────
- sync-only.js: CRYPTO_BACKEND env var for A/B testing (wasm vs ffi)
- full-testnet.js: daemon URL update (node12.whiskymine.io)
- Debug scripts for cn_scan development (debug-cn-scan/marshal/match/wasm)
- Android .gitignore and build-bundle.sh for mobile builds
