Computational Properties of Metaquerying Problems
TL;DR: In this article, the authors define several variants of metaquerying and study both the combined complexity and the data complexity of these variants, and show that, under these combined complexity measures, meta-querying is generally intractable (unless P=NP), lying sometimes quite high in the complexity hierarchies (as high as NP^PP), depending on the characteristics of the plausibility index.

Achieving Service Accountability through Blockchain and Digital Identity
TL;DR: This paper proposes a platform for achieving accountability across distributed business processes involving heterogeneous entities that need to establish various types of agreements in a standard way using blockchain and digital identity technologies.

Computational properties of metaquerying problems
TL;DR: This article defines several variants of metaquerying that encompass, as far as the authors know, all the variants that have been defined in the literature, and proves that, in general, it is within TC0, but lies within AC0 in some simpler cases.

An Infrastructure for Service Accountability based on Digital Identity and Blockchain 3.0
TL;DR: The notion of accountability node, a special case of blockchain 3.0 masternode, is identified as the key element of the devised infrastructure which acts as the main interface to cooperating services and relieves the users from the burden of having to directly interact with the blockchain.
