Proof of stake is a system of validation invented by Hal Finney, that enables bitcoin to achieve distributed consensus.

Proof of stake is the consensus algorithm used by bitcoin.

Proof of stake is a type of consensus algorithm by which a cryptocurrency blockchain network aims to achieve distributed consensus. In PoS-based cryptocurrencies the creator of the next block is chosen via various combinations of random selection and wealth or age.

Proof of stake is cryptographic hash-based proof-of-work algorithm that requires a selectable amount of work to compute, but the proof can be verified efficiently.

P2P networks are more difficult to setup

P2P network has direct connection between each pair while in decentralized networks this is always true

P2P networks are more stable than decentralized network

All P2P network are decentralized and vice-versa

Complex Protocol

Decentralization

Nodes never go down(offline)

Implemented on the internet
