Proof of Stake (PoS) is one of the core consensus mechanisms of blockchain. Its operating principle is quite simple: validators stake cryptographic assets as collateral and create new blocks based on the amount of coins they hold and stake. This mechanism reduces energy consumption and allows coin holders to participate in network operations and earn rewards.

In market capitalization rankings, the PoS camp performs strongly. ETH, as the cornerstone of the DeFi ecosystem, still holds an absolute advantage; BNB maintains the second tier thanks to the strong support of the Binance ecosystem; SOL, TRON, Cardano, and others are also showcasing their strengths in the PoS track. Additionally, new generation blockchains like Sui, Avax, Ton, and Polkadot are competing for market share through the PoS mechanism. The common point among these mainstream tokens is that they establish relatively stable validator networks through staking mechanisms, providing a solid foundation for ecosystem development.
