Second, light clients employ secure consensus algorithms such as Proof of Work (PoW) and Proof of Stake (PoS), which can effectively resist attackers' opportunities to gain significant accounting rights through malicious actions. Additionally, light clients can communicate with other nodes to obtain the latest status of the blockchain in real-time, ensuring the integrity of the blockchain held by themselves."}]}],"pr":"29cbaeed229f878cee56db6f0267413e44ce3dbfcf68f34d1370ac915e8bec24"}
