Peer-to-peer (P2P) refers to a decentralized communication and computing model in which participants in a network, often referred to as “peers,” interact directly with one another without the need for a centralized intermediary.
These P2P networks enable peers to share resources, information, or services among participants. P2P systems often enhance efficiency, reduce the risk of single points of failure, and promote distributed and autonomous interactions among users
Proof-of-Stake (PoS) is a blockchain consensus mechanism in which validators are chosen to create new blocks and secure the network based on the amount of cryptocurrency they "stake" or lock up as collateral.
Blockchain networks use the PoW consensus technique to verify transactions and secure the network. PoW was first presented as a key component of the Bitcoin blockchain by its creator, Satoshi Nakamoto.
