OP_RETURN is a script opcode used to mark a transaction output as invalid. Use it to encode messages into the Bitcoin blockchain.
Engraving a message into the bitcoin blockchain is possible. I used the free(!) service EternityWall.it It's extraordinarily simple.

If no one has used it that day, your message will be in the next block. Good luck!
