One question about the PCS

[Wangjun24]

I saw the article introducing Orion + (a variant of multilinear KZG (Orion)) in section 7, but the module in the code is multilinear KZG (Orion), so which one is it ?

[chancharles92]

The codebase only implements the multilinear version of KZG (which is different from Orion). We didn't implement Orion nor Orion+.

[Wangjun24]

So can you give me a mathematical principles or mathematical basis of the multilinear version of KZG implemented in the codebase ? I would be very grateful if it could.

Do you mean the paper/spec for it? It was originally proposed in [PST13] And there is a clean specification in the Construction 2 of the vSQL paper
