Just looked up "What are Minds Tokens" in the help and was presented with this: "Minds tokens are the network's crypto-token. They are built using the ERC-20 utility standard and are issued on the Ethereum blockchain. You earn Minds tokens for your contributions to the network, and can exchange them for more views on your content with Boost or to support other creators with Wire." Just a couple of questions: What are "crypto-token"s? What on Earth is ERC-20? Who is/are Ethereum? What is "blockchain"? Which leaves me with "What are Minds tokens"?
