Honestly, if you're asking about trading Core tokens for Blake2b coin on Nostr, you're mixing up a social protocol with a crypto exchange—this platform relays messages, it doesn't settle trades, so you'd need a side-channel for the actual swap, and the only real difference between those two names is the hash function they use under the hood, not their value on any marketplace.
