Main development tasks and choices tracking list

[ghost]

Tracking all major tasks and decisions to be made, both roughly in order of importance.

Decisions:

• [ ] ~~Choose a BLS signature crate/library/implementation and/or choose to write a new one~~ #23
• [ ] Choose symmetric key crypto primitives #10
• [ ] Choose signature scheme for DKG participant identities #11

Tasks:

• [ ] ~~Implement integrate BLS signatures~~ #23
• [ ] Implement group secret key compatible signature (if necessary)
• [x] Integrate threshold decryption crate and/or contribute upstream #26
• [ ] Side-channel analysis #16
• [x] Implement loading of trusted setup #17
• [ ] Implement all scalability and performance enhancements #5
• [ ] Implement key refresh #18
• [ ] Implement randomness beacon #27
• [ ] #54
• [ ] #77
• [ ] #78
• [ ] #79

We're also dependent on some external tasks:

• [ ] Improve arkworks Fp12 performance https://github.com/arkworks-rs/algebra/issues/121
• [x] Improve arkworks subgroup check #14
• [ ] Contribute tests to arkworks hash-to-curve https://github.com/arkworks-rs/algebra/pull/343
• [ ] Use hash-to-field/hash-to-curve to arkworks https://github.com/arkworks-rs/algebra/pull/343

Main blockers at the moment:

• Hash to curve still not implemented
• Key-committing AEAD implementation needed
• Operations that can be parallelize should be using rayon or similar
