Zcash DNS seeder

This is a CoreDNS plugin that scrapes addresses of peers from a Zcash network. It's intended as a safer, more configurable, and more scalable replacement for the zcash-seeder project.

It's written in Go and uses btcsuite for low-level networking.

Build instructions

This code cannot be used independently of CoreDNS. See coredns-zcash for instructions.

CoreDNS configuration

A sample Corefile that configures seeders on a domain for each network, using two local Zcash nodes for bootstrap:

mainnet.seeder.example.com {
    dnsseed {
        network mainnet
        bootstrap_peers 127.0.0.1:8233
        crawl_interval 30m
        record_ttl 600
    }
}

testnet.seeder.example.com {
    dnsseed {
        network testnet
        bootstrap_peers 127.0.0.1:18233
        crawl_interval 15m
        record_ttl 300
    }
}

# Returns 200 OK on .:8080/health
. {
    health :8080
}
