From an article by Dr. ir Johannes Drooghaag :
Blockchain, by some seen as the answer to every problem, is promoted by many, including myself, as a possible solution for many cyber security issues. The structure of blockchain, combining distributed ledger, consensus on proof of work and proof of stake, encryption by design and linked blocks, provides a lot of layers of protection. This does however not mean that blockchain can’t be hacked at all, it just means that it would take a lot of effort and resources to do so.
What we have to be very careful with is creating false sense of security, something I keep stressing during my workshop Cybersecurity for Road Warriors (and Couch Potatoes) and publications on this topic, by hyping the security aspects way beyond reality. With the hype around blockchain and all blockchain based crypto-currencies, and “better than anything because we use blockchain” projects, we are setting ourselves up for yet another security myth by believing that blockchain is unhackable. This article is a collection of findings and theories during research on the currently known safety issues related to blockchain. Some attack vectors are already out in the field and have lead to high profile thefts and hacks, others are theoretical and listed for the purpose of demonstrating the concept.

Hybrid vesicles of lipids and peptides release drug payload on warming
Nanoscale drug-delivery capsules that release their therapeutic cargo when triggered by a temperature change could boost the efficacy and reduce the side effects of many drugs. Researchers at RIKEN have combined lipids and peptides [...]
Platinum nanoparticles for selective treatment of liver cancer cells
In recent years, the number of targeted cancer drugs has continued to rise. However, conventional chemotherapeutic agents still play an important role in cancer treatment. These include platinum-based cytotoxic agents that attack and [...]
A cell-killing strategy to slow aging passed its first test this year
A red-hot anti-aging strategy quietly passed its first test earlier this year after 14 volunteers took drugs meant to kill off old, toxic cells in their bodies. The small study in people with [...]
Laboratory’s nanopore research hits a nerve
Since the discovery of biological ion channels and their role in physiology, scientists have attempted to create man-made structures that mimic their biological counterparts. New research by Lawrence Livermore National Laboratory (LLNL) scientists and [...]
Warm-cold-textile developed – fibers with nano-coating
Sometimes it is too cold for us and then too warm again - annoying dressing-undressing of sweaters and co. Is therefore required. However, that may change: researchers have developed a sophisticated textile that can [...]
Nanotechnology, Nanomedicine, and AI: What is Global Health Care Equivalency (GHCE)
What is Global Health Care Equivalency (GHCE)? Looking ahead over the next 10-30 years, with the rapid emergence of, and synergies between, the disciplines of nanotechnology, nanomedicine, and AI, we can envisage a future [...]
What keeps spiders on the ceiling?
Hunting spiders easily climb vertical surfaces or move upside down on the ceiling. A thousand tiny hairs at the ends of their legs make sure they do not fall off. Like the spider’s [...]
