merge-input-shares

The aim of the merge-input-shares command is to take input shares originating from multiple parties and merge them into a single input share file to be used for witness generation.

A use case for this would be to have multiple parties provide different parts of the input to the MPC computation parties.

Example

co-noir merge-input-shares --inputs test_vectors/poseidon_input2/Prover1.toml.0.shared --inputs test_vectors/poseidon_input2/Prover2.toml.0.shared --protocol REP3 --out test_vectors/poseidon_input2/Prover.toml.0.shared

The above command takes the two input shares Prover1.toml.0.shared and Prover2.toml.0.shared (note both are intended for party 0) and combines them into a single input share Prover.toml.0.shared.
