Flags and Subcommands

Setting up a Tangle Network node involves various flags to configure its operation. This guide elucidates the commonly used flags and provides instructions on how to view the complete list.

Networking:

• --port: Define the TCP port for peer-to-peer protocols.
• --rpc-port: Unified port for both HTTP and WS connections.
• --in-peers: Limit on accepted incoming connections (Default: 25).
• --out-peers: Limit on maintained outgoing connections (Default: 25).

Execution:

• --execution: Choose the execution strategy for all contexts based on the runtime compilation:

  • native: Use only the native build.
  • wasm: Use only the Wasm build.
  • both: Use both native and Wasm builds.
  • nativeelsewasm: Use native; if it fails, use Wasm.

• --wasm-execution: Method for executing Wasm runtime code:

  • compiled: Uses the Wasmtime compiled runtime (default).
  • interpreted-i-know-what-i-do: Uses the wasmi interpreter.

State & Database:

• --state-pruning: Define the state pruning mode:

  • archive: Retain the full state of all blocks.
  • <number-of-blocks>: Retain state only for a specified number of blocks.

• --trie-cache-size: Set the internal state cache size.

• --db-cache: Limit the database cache’s memory usage. Recommended: 50% of server RAM.

File Paths & Chain Spec:

• --base-path: Path where chain data resides.
• --chain: Chain specification to use; can be a file path.

Telemetry & Naming:

• --name: Assign a name to the node for telemetry.
• --telemetry-url: URL for the telemetry server. Can specify multiple URLs.

Ethereum Compatibility (Frontier):

• --eth-log-block-cache: Limit for the LRU cache size for block data (Default: 300,000,000).
• --eth-statuses-cache: Limit for the LRU cache size for transaction statuses (Default: 300,000,000).

Syncing:

• --sync: Configure the blockchain syncing mode:
  • full: Download and validate the full blockchain history.
  • fast: Download blocks without execution and get the latest state with proofs.
  • fast-unsafe: As ‘fast’, but without downloading state proofs.
  • warp: Download only the latest state and proof.
