I still don't get it after reading the article. Although to be honest, I don't want a 5 year old explanation. I want a technical breakdown of how blockchain technology works without any mention of bitcoin or currency or mining. I feel like Bitcoins really cloud my understanding of it and narrows it down to a subset of its use cases. Really I want to understand better how it can be used as a distributed P2P database of transactions and how exactly it has security and history built in. Anyone have resources? Everything I find seems to have only fin-tech in mind.
