polkadot 命令

常用示例

说明

polkadot is the reference node implementation for the Polkadot blockchain network, a multi-chain protocol enabling cross-chain interoperability. The node participates in the network by validating transactions, producing blocks, and relaying messages between parachains. The node can operate as a full node (syncing and verifying the chain), a validator (participating in consensus), or a collator (producing blocks for parachains). Built on the Substrate framework as part of the polkadot-sdk monorepo and written in Rust.
