Hi Kev, As for the last question, Tauchain Agoras is a currency and knowledge exchange and creation platform, unlike other cryptos. Agoras uses Tau, a decentralised network that lets users write and run code in natural language. Tau-verified smart contracts let Agoras users trade knowledge, computer resources, and financial instruments. Agoras also wants self-amendment, hivemind, and computational resource and derivative markets. Agoras is a knowledge economy vision, not just a currency. That's the main difference to me.
