I believe the Algorand blockchain, which the Note token will be hosted on, is a Proof-of-Stake (POS) instead of Proof-of-Work (POW) blockchain like Bitcoin. There weren’t many (any) details about this in the white paper, but that would mean there aren’t “miners” in the traditional sense of Proof-of-Work blockchains like Bitcoin and others.
Either way, it is a “crypto”. I need to read more to understand how the dividend payments will work, since it sounds like you’ll be paid in a USD(?) stablecoin rather than being paid dividends in more Note tokens.
