In the proof-of-stake (PoS) mechanism, miners need to pledge their interest in cryptocurrency to obtain a randomly selected Opportunities for validators.
What is a validator? what's the effect? Please refer to the "What is a Node/Validator" section.
This process is like a lottery. The more chips (Coin) you invest, the greater your chance of winning. Unlike in the PoW mechanism, where miners are incentivized by block rewards (newly generated Coins), validators with more stakes will receive greater rewards.
PoS is regarded as an alternative to PoW that is more sustainable, environmentally friendly, and better resistant to 51% attacks.
However, PoS has been questioned as it still favors entities with more tokens, which may lead to centralization-related risks. In addition, it still involves mining and does not solve the obstacles in the commercial application of consensus mechanisms. Common PoS platforms include Cardano (ADA), Solana (SOL), and Tezos (XTZ).
