It requires nodes (miners) in the network to compete for generating new blocks by solving complex mathematical problems. The difficulty of solving these problems automatically adjusts with the total computing power of the network to ensure that the generation speed of blocks is approximately one every 10 minutes. Solving these problems requires a large amount of computing resources, which is called"}]}],"pr":"fd37a583f08378af56cd275c9ed070a9e8eec395b1d8bd62fd20447c86b01060"}
