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.
