A collection of utilities used by our other libraries in this workspace.

  • Pedersen commitment
  • Elgamal encryption, including Hashed Elgamal
  • finite field utilities like inner product, weighted inner product, hadamard product, etc.
  • multiscalar multiplication (MSM) like Fixed Base MSM
  • polynomial utilities like multiplying polynomials, creating polynomial from roots, etc.
  • An efficient way to check several equality relations involving pairings by combining the relations in a random linear combination and doing a multi-pairing check. Relies on Schwartz–Zippel lemma.
  • An efficient way to check several equality relations involving scalar multiplications by combining the relations in a random linear combination and doing a single multi-scalar multiplication check. Relies on Schwartz–Zippel lemma.
