Generally, the consensus algorithm sets the discount levels of transaction fees based on factors such as transaction priority, miner's contribution, and network congestion. In different consensus algorithms, the rewards obtained by miners for behaviors such as packaging transactions, maintaining network security and stability also vary, thereby affecting the discount level of transaction fees. In addition, in order to maintain the healthy development of the blockchain network, developers will dynamically adjust the transaction fee based on the actual situation of the network. In summary, the discount levels of transaction fees in blockchain are the result of the combined action of various factors."}]}],"pr":"d6f522a59a19f7f73dbc54d5648deb988275163150af2158eb646bed441d54c5"}
