The Paradox of Technological Déjà Vu

Blockchain is one of several technologies du jour. It combines clever methods from peer-to-peer decentralized computing to provide an online tracing function for virtual transactions, and, once someone sets it up, it requires minimal intervention from a central auditor. While Bitcoin is the most well-known application of this innovative computer science, verification of authenticity and identity are key functions for many transactions. There could be considerable value in creating low-cost and reliable (read: hackerfree) automated approaches in virtual environments.
