At this point, most people either eye-roll or get excited at the mention of blockchain, the system behind Bitcoin and other cryptocurrencies that logs transactions across a network of computers, making it impossible to cheat and creating an immutable record of each deal or exchange.
Anyone can create a blockchain, and its open-source nature has led to a host of imitations, some more successful than others, as well as novel uses for the technology, from tracking the origin of fish to proving the authenticity of luxury goods.
While it suffers from the same libertarian excesses that have dogged the cryptocurrency boom, from scams to staggering carbon footprints, blockchain technology continues to attract interest, investment, and, consequently, experimentation.
There are a lot of problems to solve and a lot of eyes on the blockchain, so stay tuned.
