I ran across this exchange with Ghost CEO John O'Nolan on the Product Hunt announcement:
Levelsio:
Wow great work, do you think payments will start to also go this way with Ghost in the future? As ActivityPub is decentralized, maybe having some decentralized type payments fit into the future
John O'Nolan replied:
yeah! I think crypto is actually starting to get interesting for the first time now, because most people are no longer interested in it. Generally that signals the end of the hype phase and the beginning of practical utility - so I’m very interested in exploring how decentralised payments could work in Ghost in the future. There are all kinds of interesting and legitimate and interesting usecases which Stripe (mostly Visa/Mastercard) refuse to support
