By utilizing a stake-based accounting method, the PoS mechanism gives nodes with higher stakes more say in the network. Specifically, the PoS mechanism filters eligible nodes to become validator nodes by setting certain thresholds, such as pledging a certain number of tokens. Then, the system selects a portion of participants based on an algorithm to act as block producing nodes, responsible for verifying transactions and generating new blocks. In this way, the PoS mechanism preserves the security of the Proof of Work (PoW) mechanism while reducing the resource consumption and efficiency issues during the mining process."}]}],"pr":"7d1999a4681093f23202806248e68cf09743db0ec660a6c7ae77493dc872cd37"}
