Can people change their primary account (setting one secondary account as the new primary)? This would be useful for researchers who use the school's email address but relocate to another...

@rozbb I found that curve25519-dalek's `4.0.0-pre.1` already has the new version of `rand`.

We can just move this one? https://github.com/FindoraNetwork/ark-bulletproofs-secq256k1/tree/main/src/curve/secp256k1 With the recent algebra library upgrade, this should be pretty easy. I just need a yes or no.

Let me double check---I suspect that 256 can fit curve25519 but not secp256k1.

The problem seems to be a decision between two choices: - panic when the divisor is zero - return none when the divisor is zero which one is better? what...

(ideally we will try not to panic)

I checked the paper Section 6, page 11, https://eprint.iacr.org/2008/013.pdf, it said "if a is a square in k and d is a nonsquare in k." Should the second condition `assert!(a.sqrt().is_none());`...

@yelhousni @simonmasson @zhenfeizhang @asanso Do you think it would be possible to sample another Bandersnatch with d/a being a quadratic residue?

following up on the previous response from @yelhousni So, as long as we work on a prime-order subgroup, the issue is gone?

The `serialize-derive` repo is often used in a project by adding a dependency on `serialize` with the feature `derive`. https://github.com/arkworks-rs/algebra/blob/master/serialize/src/lib.rs#L19 This allows the Rust to derive the canonical serialization and...
