Struct powersoftau::Accumulator

pub struct Accumulator { /* fields omitted */ }

The Accumulator is an object that participants of the ceremony contribute randomness to. This object contains powers of trapdoor tau in G1 and in G2 over fixed generators, and additionally in G1 over two other generators of exponents alpha and beta over those fixed generators. In other words:

• (τ, τ², ..., τ^{222 - 2}, α, ατ, ατ², ..., ατ^{221 - 1}, β, βτ, βτ², ..., βτ^{221 - 1})₁
• (β, τ, τ², ..., τ^{221 - 1})₂

Methods

impl Accumulator

fn new() -> Self

Constructs an "initial" accumulator with τ = 1, α = 1, β = 1.

fn serialize<W: Write>(
    &self,
    writer: &mut W,
    compression: UseCompression
) -> Result<()>

Write the accumulator with some compression behavior.

fn deserialize<R: Read>(
    reader: &mut R,
    compression: UseCompression,
    checked: CheckForCorrectness
) -> Result<Self, DeserializationError>

Read the accumulator from disk with some compression behavior. checked indicates whether we should check it's a valid element of the group and not the point at infinity.

fn transform(&mut self, key: &PrivateKey)

Transforms the accumulator with a private key.
