Description: ALFIS
 ALFIS (ALternative Free Identity System) is an implementation of a Domain Name System
 based on a small, slowly growing blockchain. It is lightweight, self-contained,
 supported on multiple platforms and contains DNS-resolver on its own to resolve domain records
 contained in blockchain and forward DNS requests of ordinary domain zones to upstream forwarders.
