# [−][src]Struct bulletproofs::range_proof_mpc::dealer::DealerAwaitingProofShares

A dealer which has sent the `PolyChallenge`

to the parties and
is waiting to aggregate their `ProofShare`

s into a
`RangeProof`

.

## Methods

`impl<'a, 'b> DealerAwaitingProofShares<'a, 'b>`

[src]

`pub fn receive_shares(`

self,

proof_shares: &[ProofShare]

) -> Result<RangeProof, MPCError>

[src]

self,

proof_shares: &[ProofShare]

) -> Result<RangeProof, MPCError>

Assemble the final aggregated `RangeProof`

from the given
`proof_shares`

, then validate the proof to ensure that all
`ProofShare`

s were well-formed.

If the aggregated proof fails to validate, this function
audits the submitted shares to determine which shares were
invalid. This information is returned as part of the
`MPCError`

.

If the proof shares are known to be trusted, for instance when
performing local aggregation,
`receive_trusted_shares`

saves time by skipping verification of the aggregated proof.

`pub fn receive_trusted_shares(`

self,

proof_shares: &[ProofShare]

) -> Result<RangeProof, MPCError>

[src]

self,

proof_shares: &[ProofShare]

) -> Result<RangeProof, MPCError>

Assemble the final aggregated `RangeProof`

from the given
`proof_shares`

, but skip validation of the proof.

## WARNING

This function does **NOT** validate the proof shares. It is
suitable for creating aggregated proofs when all parties are
known by the dealer to be honest (for instance, when there's
only one party playing all roles).

Otherwise, use
`receive_shares`

,
which validates that all shares are well-formed, or else
detects which party(ies) submitted malformed shares.
