- Exploration of unique ID assignment for devices across the universe.
- Comparison of random ID assignment (probabilistic uniqueness) vs. deterministic schemes.
- Random IDs: Simple, scalable, with collision probabilities made negligible by increasing bit size.
- Deterministic IDs: Centralized and decentralized schemes (Dewey, Binary, Token) with varying growth characteristics.
- Proof that any deterministic scheme must grow linearly in the worst-case.
- Simulations of ID assignment schemes under different growth models (Random, Preferential, Fitness).
- Large-scale modeling of human expansion across galaxies and its impact on ID length.
- Conclusion: Random IDs with sufficient bits (e.g., 798) are practical for universal uniqueness.
- Security considerations: Signatures for verification and error correction for robustness.
- Philosophical and practical challenges (e.g., Ship of Theseus problem, object identity).
