#+TITLE: Proof of Work vs Proof of Stake
#+ID: 0450c91b-55a5-4bcc-9bc2-2478d983be3c
* Proof of Work vs Proof of Stake
** Core Concepts
- **Proof of Work (PoW):** Uses computational energy as the primary mechanism for Sybil resistance and achieving consensus.
- **Proof of Stake (PoS):** Uses capital at risk (staked tokens) to achieve the same goal.
** Fundamental Differences
| Aspect | Proof of Work | Proof of Stake |
|--------|---------------|----------------|
| Foundation | Physics (energy) | Economics (capital) |
| Sybil Resistance | Computational cost | Financial stake at risk |
| Resource Required | Hardware/energy | Capital/tokens |
** Open Question
PoW may be more fundamentally grounded in physics, while PoS is grounded in economics. Further exploration needed on the implications of this distinction.
