Insights into concrete architecture

Can anybody explain in detail how much has concrete architecture changed after this ?

Concrete mentioned in this presentation is the TFHE Rust library that is now called TFHE-rs.
We kept the name Concrete for our TFHE compiler.

Are there no papers which is describing the concrete architecture design?

There’s an intro video here: and a bblog post that explains the architecture.

And there’s a paper on the “optimizer” which generates crypto-parameters for Concrete circuits and a blog post that explains the paper.
