it’s v easy to fake zaps no? remember when nostr:npub1u8lnhlw5usp3t9vmpz60ejpyt649z33hu82wc2hpv6m5xdqmuxhs46turz did the >21M bitcoin worth of zaps on a note or sum shit
Hell yea!
that only matters to the zapped, as well
anyone else, meh, can be faked
I'm glad you indicated counterfeit-resistant as opposed to counterfeit-proof.
Zaps are a signal into the void.
A beacon of light in a world of economic enslavement.
