Firstly, blockchain optimizes consensus mechanisms, such as Proof of Stake (PoS) and Delegated Proof of Stake (DPoS), to reduce competition between nodes and improve network performance. Secondly, the introduction of second-layer networks  (such as Arbitrum, Optimism) and application chains (such as Polkadot, Avalanche) helps to alleviate congestion on the main chain, increase transaction speed, and reduce transaction costs. Additionally, technologies such as Zero-Knowledge Proof (ZKP) ensure the security of blockchain while maintaining privacy."}]}],"pr":"59d69481f17169b9154409b987eb742fb26b3d2578031c7c06478a428fe6fdd2"}
