- utils::vec module: port a mix of vec utils from nova-study, multifolding-poc and protogalaxy-poc repos - pedersen.rs: Pedersen commitment module - other: - update FoldingScheme trait interface: rm rng, update internal types naming as agreed in today's call - update Cargo.toml dev-dependencies imports, since bn254 - grumpkin is not ready yet, use bls12-377 - bw6-761 curve cycle - transcript module: add absorb_point method
