How Does PoW Differ Fundamentally from Proof-of-Stake (PoS)?
PoW secures the network through energy expenditure and computational power (mining). PoS secures the network through economic stake, where validators are chosen based on the amount of currency they hold and are willing to "stake" as collateral.
PoW is about "work" to find a hash; PoS is about "holding" the asset and risking its loss (slashing) for malicious behavior.
Glossar
Staking Yield
Return ⎊ Staking Yield is the annualized rate of return generated from an asset committed to securing a Proof-of-Stake network, paid out in the native token as a reward for validation service.
Energy Efficiency
Optimization ⎊ Energy efficiency within cryptocurrency, options trading, and financial derivatives represents a reduction in computational resources or capital employed to achieve a given level of transactional throughput or risk-adjusted return.
Computational Power
Capacity ⎊ The computational power, within the context of cryptocurrency derivatives and options trading, fundamentally represents the aggregate processing capability available to execute complex calculations and simulations.
