It requires nodes in the network (miners) to compete  for generating new blocks by solving complex mathematical problems. The difficulty of solving these problems is automatically adjusted according to the total computing power of the network to keep the generation speed of blocks at approximately one every 10 minutes. Mining these problems requires a large amount of computing resources, and this workload guarantee ensures the security of the network."}]}],"pr":"0f392534a71950c726dfcb0e0cfe5e11944ea76d3ae311c35159e90bf3f6988e"}
