Under this rule, nodes in the blockchain network competitively solve a complex mathematical problem called Proof of Work (abbreviated as PoW). Solving these problems consumes a large amount of computing resources, thereby ensuring the security and stability of the blockchain network."}]}],"pr":"98b94cad6b7e6e351c9261a648cb0617210d4c537de80eddd78505eadcc7dd88"}
