canopic jug writes:Digital preservationist, David Rosenthal, has a blog post discussing his recent Coalition for Networked Information (CNI) talk about distributed ledger technology. CNI is a joint initiative of the Association of Research Libraries (ARL) and EDUCAUSE to promote the use of digital information technologies to advance scholarship and education. The discrepancy between the available capacity in transactions per second and what is actually needed, plus the excessive power consumption, suggests that many attempted uses for distributed ledgers are inappropriate and counterproductive.

This deliquescent salt has such a high affinity for water that it will absorb so much vapor from the surrounding air that eventually a pool of liquid forms.https://www.rtoz.org/2018/12/07/drinking-water-sucked-from-the-dusty-desert-air-using-hybrid-hydrogel/The full research paper is available on-line.Original SubmissionRead more of this story at SoylentNews.

These past failures give a foundation which can be applied to the current situation in hopes of understanding why cryptographers around the world are universally against these kinds of schemes.
