Network config options.

Fields

whitelist_only: bool

Only connect to whitelist peers.

max_peers: u32

Maximum number of allowed connected peers.

The node will evict connections when the number exceeds this limit.

max_outbound_peers: u32

Maximum number of outbound peers.

When node A connects to B, B is the outbound peer of A.

path: PathBuf

Network data storage directory path.

dns_seeds: Vec<String>

A list of DNS servers to discover peers.

discovery_local_address: bool

Whether to probe and store local addresses.

discovery_announce_check_interval_secs: Option<u64>

The interval between discovery announce message checking.

ping_interval_secs: u64

Interval between pings in seconds.

A node pings peer regularly to see whether the connection is alive.

ping_timeout_secs: u64

The ping timeout in seconds.

If a peer does not respond to ping before the timeout, it is evicted.

connect_outbound_interval_secs: u64

The interval between trials to connect more outbound peers.

listen_addresses: Vec<Multiaddr>

Listen addresses.

public_addresses: Vec<Multiaddr>

Public addresses.

Set this if this is different from listen_addresses.

bootnodes: Vec<Multiaddr>

A list of peers used to boot the node discovery.

Bootnodes are used to bootstrap the discovery when local peer storage is empty.

whitelist_peers: Vec<Multiaddr>

A list of peers added in the whitelist.

When whitelist_only is enabled, the node will only connect to peers in this list.

upnp: bool

Enable UPNP when the router supports it.

bootnode_mode: bool

Enable bootnode mode.

It is recommended to enable this when this server is intended to be used as a node in the bootnodes.

support_protocols: Vec<SupportProtocol>

Supported protocols list

max_send_buffer: Option<usize>

Max send buffer size in bytes.

reuse_port_on_linux: bool

Network use reuse port or not

reuse_tcp_with_ws: bool

Allow ckb to upgrade tcp listening to tcp + ws listening

disable_block_relay_only_connection: bool

Disable block_relay_only connection, only use for testing.

channel_size: Option<usize>

Tentacle inner channel_size.

trusted_proxies: Vec<IpAddr>

A list of trusted proxies’ IP addresses.

sync: SyncConfig

Chain synchronization config options.

proxy: ProxyConfig

Proxy related config options

onion: OnionConfig

Onion related config options
