Today we continue to build on the topic of the blockchain consensus mechanisms and we will explore Proof-of-Stake (PoS) in depth. 

In PoS token owners stake their crypto within a blockchain, meaning, they lock their crypto assets for a set period to help support the operation of a blockchain. Users who stake their tokens secure the network and will get slashed if they behave maliciously, thus being incentivized to always be honest.


  1. Energy Efficiency: PoS consumes significantly less energy compared to PoW, making it more environmentally friendly.

  2. Scalability: PoS can handle more transactions per second, making it more scalable.


  1. Centralization Risk: Large stakeholders can potentially have more influence, leading to centralization concerns.

  2. Initial Distribution: The system can be biased towards those who already hold large amounts of the cryptocurrency, leading to wealth concentration.
