Just to chime in since I'm the OP of this subcomment.

Generating 128 byte identifiers is ridiculously overkill. I can safely say if you generate 128 byte identifiers securely, the earth will cease to exist before a collision is found.

You would be safe generating cryptographically secure 128 bit identifiers and looking them up. It is trivial to generate IDs that will not collide.
