Fields

interval_period_ms: Option<u64>

Query peers for their latest checkpoint every interval period.

If unspecified, this will default to 5,000 milliseconds.

target_concurrent_connections: Option<usize>

Target number of concurrent connections to establish.

If unspecified, this will default to 4.

peers_to_query: Option<usize>

Number of peers to query each interval.

Sets the number of peers, to be randomly selected, that are queried for their known peers each interval.

If unspecified, this will default to 1.

peer_query_timeout_sec: Option<u64>

Timeout for individual peer query requests in discovery protocol.

If unspecified, this will default to 1 second.

get_known_peers_rate_limit: Option<NonZeroU32>

Per-peer rate-limit (in requests/sec) for the GetKnownPeers RPC.

If unspecified, this will default to no limit.

access_type: Option<AccessType>

See docstring for AccessType.

allowlisted_peers: Vec<AllowlistedPeer>

Like seed_peers in P2pConfig, allowlisted peers will always be allowed to establish connection with this node regardless of the concurrency limit. Unlike seed_peers, a node does not reach out to allowlisted_peers preferentially. It is also used to determine if a peer is accessible when its AccessType is Private. For example, a node will ignore a peer with Private AccessType if the peer is not in its allowlisted_peers. Namely, the node will not try to establish connections to this peer, nor advertise this peer’s info to other peers in the network.

max_concurrent_address_verifications: Option<usize>

Maximum number of concurrent address verification attempts. This prevents overwhelming the network when verifying many peers at once.

If unspecified, this will default to 10.

address_verification_timeout_sec: Option<u64>

Timeout for individual address verification attempts.

If unspecified, this will default to 3 seconds.

address_verification_total_timeout_sec: Option<u64>

Total timeout for all address verification attempts to prevent DoS attacks.

If unspecified, this will default to 8 seconds.

address_verification_failure_cooldown_sec: Option<u64>

Cooldown period in seconds for peers whose address verification failed. During this period, new peer info from the same peer will be ignored. Set to 0 to disable the cooldown feature entirely.

If unspecified, this will default to 600 seconds (10 minutes).

cooldown_cleanup_interval_sec: Option<u64>

Interval for cleaning up old entries from the verification failure cooldown list.

If unspecified, this will default to 300 seconds (5 minutes).
