Blockchain development
Delving into the realm of blockchain development, developers often rely on testnet nodes for experimentation and testing. Specifically, when working with the Binance Smart Chain (BSC) testnet nodes, what are the key steps involved in setting up and running a BSC testnet node? Furthermore, how does the utilization of testnet nodes contribute to the efficient development and deployment of decentralized applications (DApps) on the Binance Smart Chain?
