Litecoin Watch beginner and controversy research package, v1, 1 October 2026.
Original isolated Litecoin Core 0.21.5.8 experiment: old receive-address reuse, default policy rejects opt-in replacements, enabled -mempoolreplacement=1 rejects low fee and accepts sufficient replacement, confirmed input conflict rejected. 26 assertions. No peers or mainnet funds.
Run: python test-core.py /absolute/path/to/litecoind /absolute/path/to/new-output-directory
Requires Python standard library and verified Core 0.21.5.8. RPC helper must sit beside script. A fresh temporary regtest directory is created and removed. Public signed regtest transactions contain no private keys and are not mainnet transactions. Random wallets make addresses and transaction IDs differ on reruns; behavioral checks should hold.
ETF arithmetic: python calculate-etf.py (writes calculations beside script). Hypothetical constant annual fees with daily reduction, 365-day years. Normalized units are not actual LTCC holdings. Price/NAV rounding range is an arithmetic possibility, not recovered issuer precision. No investment forecasts.
Hardware security article is a source-backed decision guide, not a comparative hardware test or an estimate of attack success rates. Address experiment covers transparent P2WPKH Core wallet receipts; no exchange, restoration discovery, MWEB or mobile GUI test.
