ℹ️ A node - in Polkadot - is a binary executable, whose primary purpose is to execute the runtime.
🔗 It communicates with other nodes in the network, and aims for consensus among them.
⚙️ It acts as a remote procedure call (RPC) server, allowing interaction with the blockchain.
👉 Learn more about the architecture, and a difference between a node and a runtime here.
👇 Here are the most important files in this node template:
chain_spec.rs: A chain specification is a source code file that defines the chain's initial (genesis) state.service.rs: This file defines the node implementation. It's a place to configure consensus-related topics. In favor of minimalism, this template has no consensus configured.
