Module sp_core::bandersnatch

VRFs backed by Bandersnatch, an elliptic curve built over BLS12-381 scalar field.

The primitive can operate both as a regular VRF or as an anonymized Ring VRF.

Modules

• ring_vrf
  Bandersnatch Ring-VRF types and operations.
• vrf
  Bandersnatch VRF types and operations.

Structs

• Pair
  Bandersnatch secret key.

Constants

• CRYPTO_ID
  Identifier used to match public keys against bandersnatch-vrf keys.
• PREOUT_SERIALIZED_SIZE
  The byte length of serialized pre-output.
• PUBLIC_SERIALIZED_SIZE
  The byte length of serialized public key.
• SEED_SERIALIZED_SIZE
  The byte length of secret key seed.
• SIGNATURE_SERIALIZED_SIZE
  The byte length of serialized signature.
• SIGNING_CTX
  Context used to produce a plain signature without any VRF input/output.

Type Aliases

• Public
  Bandersnatch public key.
• Signature
  Bandersnatch signature.
