Public libraries are trusted by their communities as places that community members can turn to for unfettered information access and as places to go for information in times of need. Combining this trust with the power of Internet access and support makes public libraries even more critical within their local communities. The trust placed in libraries is also important in balancing the lack of confidence that many citizens place in other government institutions as well as in the Internet.\cite{Jaeger_2007}It is my view that a key theme of the proposal to IMLS ought to be exploring ways in which blockchain technologies may be used to enhance trusting relationships between libraries and their clients, including but not limited to Edublocks.

Accessed January 7 2017. https://www.gov.uk/government/publications/distributed-ledger-technology-blackett-review.) For example, there are proposals to use blockchains as a basis for distributed archiving and preservation and as a basis for research data management, and while each of these activities has more often been within the purview of academic institutions, it may be argued that they are also areas in which public libraries should be much more active. (See: Buntinx, Jean-Pierre. 2016. ”Why The Blockchain Needs To Replace Archaic Archiving Methods”. Bitcoin News. Accessed January 7 2017. https://news.bitcoin.com/blockchain-replace-archaic-archiving/; Buntinx, Jean-Pierre. 2016. ”Scientific Research Proof Of Concept Validates Bitcoin Technology”. Bitcoin News.

Given that such enhancements are essential to success in digital curation and preservation, and in view of the fact that libraries lack the resources to create the metadata needed, distributed approaches governed by trusted relationships between annotators and libraries may be viewed as a necessary condition for preserving much of what is at risk in the digital environment today. This perspective is based on the notion that the successful preservation of a digital object requires adequate metadata, and that in the absence of such metadata only a file of little or no value has been saved. The generation of such metadata would also enhance the discovery of objects that currently exist beyond the bibliographic mainstream, in places like digital archives and repositories and content management systems.The second phase of the project would be concerned with issues of feasibility — see “Avoiding the pointless blockchain project” — and return on investment for public libraries.
