This NIP introduces a protocol for creating ephemeral events that are weakly tied to a public key, allowing ephemeral interactions without permanent attachment to the author's identity.

This NIP introduces a protocol for creating temporary events that are weakly tied to a public key, enabling ephemeral interactions without permanently binding them to the author's identity. This NIP introduces a protocol for creating deniable events that are weakly tied to a public key, enabling ephemeral interactions without permanently binding them to the author's identity.
We aim to produce events that are weakly tied to other public keys — events that are **probably** associated with that public key (e.g., Alice's) but cannot be **proven** to originate from it.
