dcrseeder is a crawler for the Decred network, which exposes a list of reliable nodes via a built-in HTTP server.
When dcrseeder is started for the first time, it will connect to the dcrd node
specified with the -s flag, send a getaddrs request, expecting an addr
message response. This message contains hostnames and IPs of peers known by the
node. dcrseeder will then connect to each of these peers, send a getaddrs
request, and will continue traversing the network in this fashion. dcrseeder
maintains a list of all known peers and periodically checks that they are
online and available. The list is stored on disk in a json file, so on
subsequent start ups the dcrd node specified with -s does not need to be
online.
When dcrseeder is queried for node information, it responds with details of a random selection of the reliable nodes it knows about.
Go 1.20 or newer.
To build and install from a checked-out repo, run go install in the repo's
root directory.
To start dcrseeder listening on localhost:8000 with an initial connection to working testnet node 192.168.0.1:
$ ./dcrseeder -s 192.168.0.1 --testnet --httplisten=localhost:8000
You will then need to redirect HTTPS traffic on your public IP to localhost:8000
