Few projects have done as much to explore crypto micropayments as the year-old Yalls blog created by Lightning Labs developer Alex Bosworth.
From April through early November, Bosworth said, blog participants have processed nearly 20,000 invoices with the Lightning Network, a bitcoin scaling solution that makes micropayments feasible by keeping them off the blockchain, sidestepping network transaction fees.
It costs roughly one cent to read a Yalls article, half a cent to leave a comment on a post, and 10 cents to react to a post with an emoji. Publishing an article is free.
