Hosts Cache

The node.hosts_file configuration setting controls the path to a cached set of peers. An in-memory host pool is created at startup from the cache.

If the cache is empty or not found the host pool will initialize from a set of well-known seed nodes. To specify your own seed nodes initialize the hosts file with the desired nodes.

The host pool is periodically updated using peer information and not written until service shutdown. The capacity of the host pool can be configured using the node.host_pool_capacity configuration setting.
