Enum solana_sdk::poseidon::Parameters

#[repr(u64)]
pub enum Parameters {
    Bn254X5 = 0,
}

Configuration parameters for the Poseidon hash function.

The parameters of each configuration consist of:

• Elliptic curve type: This defines the prime field in which the cryptographic operations are conducted.
• S-Box: The substitution box used in the cryptographic rounds.
• Full rounds: The number of full transformation rounds in the hash function.
• Partial rounds: The number of partial transformation rounds in the hash function.

Each configuration variant’s name is composed of its elliptic curve type followed by its S-Box specification.

Variants

Bn254X5 = 0

Configuration using the Barreto–Naehrig curve with an embedding degree of 12, defined over a 254-bit prime field.

Configuration Details:

• S-Box: ( x^5 )
• Width: ( 2 \leq t \leq 13 )
• Inputs: ( 1 \leq n \leq 12 )
• Full rounds: 8
• Partial rounds: Depending on width: [56, 57, 56, 60, 60, 63, 64, 63, 60, 66, 60, 65]

Trait Implementations

impl TryFrom<u64> for Parameters

type Error = PoseidonSyscallError
