In blockchain, the calculation of transaction fees is usually related to factors such as transaction complexity, block  size, and network congestion.↵↵Specifically, blockchain networks dynamically adjust the rewards and fees for each block based on the current network conditions. Miners compete to generate new blocks by solving complex mathematical problems and packaging transactions into new blocks. Then, the blockchain network allocates corresponding rewards and fees based on the miners' contributions. This process is decentralized."}]}],"pr":"6770a5d38e103e864a189ffb2c3a2f07e7aae878a06d7404be29020108dfca86"}
