  Given a large number of online services on the Internet, from time to time,
people are still struggling to find out the services that they need. On the
other hand, when there are considerable research and development on service
discovery and service recommendation, most of the related work are centralized
and thus suffers inherent shortages of the centralized systems, e.g.,
adv-driven, lack at trust, transparence and fairness. In this paper, we propose
a ServiceNet - a peer-to-peer (P2P) service network for service discovery and
service recommendation. ServiceNet is inspired by blockchain technology and
aims at providing an open, transparent and self-growth, and self-management
service ecosystem. The paper will present the basic idea, an architecture
design of the prototype, and an initial implementation and performance
evaluation the prototype design.
