BN254's twisted edwards curve is defined here. However, the params defined in code and params defined in eip-2494 are totally different

I think they are the same curve. i.e. Baby-Jubjub

Could someone explain the differences?

#87: A=-1 to simplify group arithmetic?

In EIP-2494 the parameters are defined as:

Maybe you had a look at different curve equation parameters?

Thanks a lot! I ignore Reduced Twisted Edwards Form at the bottom...
