[−] Expand description

Represents an error during the multiparty computation protocol for proof aggregation.

This is a separate type from the ProofError to allow a layered API: although the MPC protocol is used internally for single-party proving, its API should not expose the complexity of the MPC protocol.

Variants

MaliciousDealer

[−] Expand description

This error occurs when the dealer gives a zero challenge, which would annihilate the blinding factors.

InvalidBitsize

[−] Expand description

This error occurs when attempting to create a proof with bitsize other than \(8\), \(16\), \(32\), or \(64\).

InvalidAggregation

[−] Expand description

This error occurs when attempting to create an aggregated proof with non-power-of-two aggregation size.

InvalidGeneratorsLength

[−] Expand description

This error occurs when there are insufficient generators for the proof.

WrongNumBitCommitments

[−] Expand description

This error occurs when the dealer is given the wrong number of value commitments.

WrongNumPolyCommitments

[−] Expand description

This error occurs when the dealer is given the wrong number of polynomial commitments.

WrongNumProofShares

[−] Expand description

This error occurs when the dealer is given the wrong number of proof shares.

MalformedProofShares

[−] Expand description

This error occurs when one or more parties submit malformed proof shares.

Fields of MalformedProofShares

bad_shares: Vec<usize>

A vector with the indexes of the parties whose shares were malformed.
