Enum PeerOrigin 

pub enum PeerOrigin {
    Priority,
    Discovered,
}

HOW a peer was reached, which is not the same question as whether it is reachable.

A priority peer — an operator’s TRUSTED_FULLNODE, or a full node on this machine — is preferred because it is fast and under the operator’s own control. That makes it a good peer to ASK. It does not make it an independent voice: corroboration is only worth anything when the peers agreeing came from sources an attacker cannot all supply, and a co-resident process is precisely a source a local attacker CAN supply. Priority orders discovery; it never confers authority.

So this is reported rather than decided here. A caller doing round-robin reads wants the fast peer; a caller counting agreeing opinions must count PeerOrigin::Discovered peers only. A single return value cannot serve both, and conflating them is what let one local process stand in for an entire “independent” peer set (dig_ecosystem#2648).

Variants

Priority

Reached from a configured or co-resident address tried ahead of discovery.

Discovered

Reached from a DNS introducer’s address set.
