In practice, when we fill out an envelope, we don’t need to include the sender’s information; we only need to write the recipient’s address, and there’s no need to write the recipient’s name. As long as the recipient’s address is precise enough, the letter can be successfully delivered. Not needing to write the sender’s information is equivalent to being able to write any random address. nostr:note13pu0ntgaywtjgfx0lpqlgk4sxxqcnq5aw9fcgrd88jhmuk9ytzcsy46q2c
