Dew computing services belong to a new category of dew computing that a local device provides micro-services. The key feature of dew computing services is that it serves not only the owner of the device but also the users other than the device owner. In this paper, we introduce dew computing services and propose to create an API for dew computing services. The primary considerations in creating this API are described; some essential API items are proposed. The major goal of this paper is to request for comments from the dew computing community.

Dewblock is a blockchain system based on dew computing and cloud-dew architecture. The goal of Dewblock was to implement a generic client architecture comparable to a typical blockchain system but with sufficiently low memory usage to be deployed on a personal computer or mobile phone, providing functionality consistent with a full node. In order to provide the features of a full node, the dewblock client uses the mechanisms of a cloud-dew architecture while maintaining a standard peer-to-peer architecture for internode communication. In this paper, a mobile application will be discussed, which implements Dewblock allowing it to run on any Android mobile phone. The primary intent was to prove the deployability of Dewblock on mobile platforms, and while Android was chosen here for expediency, the general principles involved can be applied to other platforms, such as iOS or personal computers.
