Don’t be fooled: Blockchains are not miracle security solutions


The idea that blockchains may bring benefits in terms of cybersecurity is a widespread myth. Even the US Department of Defense fell for this myth in a recent report “DoD Digital Modernization Strategy” with plans to build a “Block Chain Cybersecurity Shield” allowing to “transmit secure messages” and “develop unhackable code.” It’s important to set the record straight on these complex topics.

However, Swiss startup Transmutex wants to reinvent nuclear energy using a lesser-known element called thorium.  Uranium’s forgotten cousin Thorium is a lead-like metal that is mildly reactive, but four times more abundant than uranium and a lot safer to handle.
