RingSelector interface with RPCRingSelector that fetches random outputs
from the daemon, excludes the real output and duplicates, and returns
the requested ring size.

Scanner interface with V1Scanner implementation for v0/v1 transactions.
Derives ephemeral keys via ECDH, generates key images, and tracks
coinbase status and unlock times.

GenerateAccount, RestoreFromSeed, RestoreViewOnly with deterministic
view key derivation (sc_reduce32(Keccak256(spend_secret))), matching
C++ account_base::generate(). Encrypted persistence via Argon2id
(time=3, mem=64MB) + AES-256-GCM in go-store.
Adds cn_sc_reduce32 to the CGo bridge for scalar reduction mod l,
required to convert a hash output into a valid Ed25519 secret key.

Parses tags 22 (tx public key), 14 (unlock time), and 11 (derivation
hint) from raw extra bytes. Unknown tags are skipped. Raw bytes preserved
for round-tripping.
Adds PublicKey.IsZero() to types package.

24-word Electrum encoding (4 bytes → 3 words × 8 groups) plus CRC32
checksum word. 1626-word dictionary extracted from C++ source.

11 tasks covering mnemonic seeds, TX extra parsing, account management,
transfer storage, scanning, signing, ring selection, tx building, and
wallet orchestration. TDD with complete code for every step.

Add comprehensive tests exercising regular transaction processing through
the sync pipeline (key image marking, output indexing, cumulative
difficulty) and not-found error paths for all query methods. Coverage
rises from 65.8% to 80.1%.

Add NetworkIDMainnet and NetworkIDTestnet 16-byte UUIDs for P2P
handshake, ClientVersion constant, and NetworkID field to ChainConfig.
Add local replace directive for forge.lthn.ai/core/go-p2p.

CLSAG_GG generation and verification with flat-buffer ring marshalling.
Cofactor helpers (PointMul8/PointDiv8) for 1/8 premultiplication handling.
CLSAG_GGX and CLSAG_GGXXG verify-only bindings (GGX sig size tests).
Bulletproofs+, BGE, and Zarcanum verification stubs — implementation
deferred to Phase 4 when RPC provides real on-chain proof data.
19 tests pass, 3 skipped (proof stubs), all clean with -race.

Standard signature sign/verify round-trip with negative tests (wrong key,
wrong message). Ring signature (NLSAG) uses flat buffer C API to avoid
double-pointer indirection across CGo boundary. Round-trip with 4-member
ring and wrong-message negative test. All 15 tests pass with race detector.

Original founding document for the Zano protocol extensions.
Contains raw math for return addresses, key derivation, shared
secret encryption, hybrid mining, and tiny addresses — the
cryptographic foundations that Phase 2 bridge implements.

CGo bridge to vendored upstream C++ crypto library following the MLX
pattern. Thin C API (bridge.h) as the stable contract between Go and
C++. Provenance tracking for easy upstream Zano updates.

Add consensus-critical binary serialisation for blocks and transactions,
verified by computing the testnet genesis block hash and matching the C++
daemon output (cb9d5455...4963). Fixes Phase 0 type mismatches (variant
tags, field widths, missing fields) and adds encoder/decoder, tree hash,
and block/transaction hashing.
Key discovery: CryptoNote's get_object_hash(blobdata) prepends
varint(length) before hashing, so BlockHash = Keccak256(varint(len) || blob).
