mensagem com 80 caracteres!!!
Block 724,300. February 21, 2022. Somebody in Brazil discovered Bitcoin's OP_RETURN size limit and decided to announce it.
They sent two consecutive transactions, both padded to exactly 80 bytes:
"mensagem com 80 caracteres!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
A message with 80 characters. Then 54 exclamation points to fill every last byte. The second: "mensagem2 com 80 caracteres" — with 53 exclamation points.
Someone found the ceiling and made as much noise as Bitcoin would let them.
