I love this idea of using ecash as message stamps. This idea has huge potential for drawing value into the digital ecosystem versus the more scary idea of using ecash as an alternative currency.

Remember, proof of work was invented by Cynthia Dwork in 1993 to fight spam and used by Adam Back for honest digital currency.

Message stamps build on these developments and are now possible with Cashu and Lightning. nostr:note1kta54vdhagauvp3gvyur350g7x804y04kyphefn8up7wf4veg4fqj8cm2p
