Parameters used to create the network configuration.

Fields§

§bootnodes: Vec<MultiaddrWithPeerId>

Specify a list of bootnodes.

§reserved_nodes: Vec<MultiaddrWithPeerId>

Specify a list of reserved node addresses.

§reserved_only: bool

Whether to only synchronize the chain with reserved nodes. Also disables automatic peer discovery. TCP connections might still be established with non-reserved nodes. In particular, if you are a validator your node might still connect to other validator nodes and collator nodes regardless of whether they are defined as reserved nodes.

§public_addr: Vec<Multiaddr>

The public address that other nodes will use to connect to it. This can be used if there’s a proxy in front of this node.

§listen_addr: Vec<Multiaddr>

Listen on this multiaddress.

By default: If --validator is passed: /ip4/0.0.0.0/tcp/<port> and /ip6/[::]/tcp/<port>. Otherwise: /ip4/0.0.0.0/tcp/<port>/ws and /ip6/[::]/tcp/<port>/ws.

§port: Option<u16>

Specify p2p protocol TCP port.

§no_private_ip: bool

Always forbid connecting to private IPv4/IPv6 addresses (as specified in RFC1918), unless the address was passed with --reserved-nodes or --bootnodes. Enabled by default for chains marked as “live” in their chain specifications.

§allow_private_ip: bool

Always accept connecting to private IPv4/IPv6 addresses (as specified in RFC1918). Enabled by default for chains marked as “local” in their chain specifications, or when --dev is passed.

§out_peers: u32

Specify the number of outgoing connections we’re trying to maintain.

§in_peers: u32

Maximum number of inbound full nodes peers.

§in_peers_light: u32

Maximum number of inbound light nodes peers.

§no_mdns: bool

Disable mDNS discovery. By default, the network will use mDNS to discover other nodes on the local network. This disables it. Automatically implied when using –dev.

§max_parallel_downloads: u32

Maximum number of peers from which to ask for the same blocks in parallel. This allows downloading announced blocks from multiple peers. Decrease to save traffic and risk increased latency.

§node_key_params: NodeKeyParams§discover_local: bool

Enable peer discovery on local networks. By default this option is true for --dev or when the chain type is Local/Development and false otherwise.

§kademlia_disjoint_query_paths: bool

Require iterative Kademlia DHT queries to use disjoint paths for increased resiliency in the presence of potentially adversarial nodes. See the S/Kademlia paper for more information on the high level design as well as its security improvements.

§kademlia_replication_factor: NonZeroUsize

Kademlia replication factor determines to how many closest peers a record is replicated to.

Discovery mechanism requires successful replication to all kademlia_replication_factor peers to consider record successfully put.

§ipfs_server: bool

Join the IPFS network and serve transactions over bitswap protocol.

§sync: SyncMode

Blockchain syncing mode.

§max_blocks_per_request: u32

Maximum number of blocks per request.

Try reducing this number from the default value if you have a slow network connection and observe block requests timing out.
