And don't forget about more particular examples like smart contracts. For example, I follow closely SciDex. They are creating a new type of smart contract generator for complex transactions. So that even regular businesses that need legally binding contracts can be on the blockchain. Thats improving the whole blockchain ecosystem, if you ask me.
Love that idea. Blockchain has so much utility in this day of world. We just need to make it so that non-techy average joe can easily use it. Just like WhatsApp or Messenger, once installed, even my parents can use. (my dad had difficulty figuring out how to copy-and-paste file from one folder to another)
