It is somewhat ironic that this paper comes from a Dutch University, since Holland has historically made a great deal of money from acting as a middle-man, as indeed it continues to do.

Searching some referenced papers I found http://projectm-online.com/investing/the-value-of-trust/ which is IMHO a nice high level treatment of the space.

The paper questionably approaches the subject theoretically through a pre-digital era reference which divides trust through conventional relations of 1990s society, which is of dubious currency.

It also refers to prior work from the same university https://repository.tudelft.nl/islandora/object/uuid:c1816da8... which appears to be a BS thesis on settlement-system neutral market protocols, post-dating my own published work on the same - http://www.ifex-project.org/our-proposals/ifex/2012-04-11-pa... - by some five (4-5) years.

The treatment of trust in decentralized networks is high level only and in parts not of an academic quality of writing, for example making inferences that 15 years of prior formal work is valueless because it has not been publicly deployed.
