## Conclusion

This feature matrix demonstrates that all core QuDAG CLI features can be adapted for WASM, though with varying levels of complexity. The most challenging areas are:

1. **Network layer adaptation** - Requires complete transport replacement
2. **Cryptographic performance** - Needs careful optimization
3. **Process management** - Requires Service Worker architecture

The implementation is technically feasible with an estimated 22 developer-weeks of effort, resulting in a ~900KB compressed binary with 85-90% of native performance for most operations.
