The actor model provides a powerful abstraction for message passing but lacks communication consistency and forces actors to be written in isolation. By contrast, multitier programming with RPC calculi ensures correctness and a global programming perspective. We propose a multitier actor language unifying the classic actor model with location-transparent RPC abstractions. Each actor is treated as a location, supporting remote variable access and function calls. A Cloud Haskell prototype embodies its executable semantics, validated by benchmarks and a cryptographic protocol.
