summary

Lightning currently breaks on real-world constraints: devices must be online to receive and to avoid locking HTLC liquidity, single-use invoices block offline receive, and watchtowers can’t enforce HTLCs without leaking channel info. Practical fixes under development include onion messages for offline notifications, trampoline routing to let intermediaries retry payments, and PTLCs via adapter signatures (Taproot) for multi-use QR invoices. Chain issues need Bitcoin Core changes (package replacement RPC and tx version 3) and mempool/CPFP work; some pieces land now, others need years.
