With MPC technology, the client’s vault is controlled by three individual shards that are created and held in isolation at all times by three independent parties.
MPC technology provides enhanced security as no private key is ever created or reassembled for signing.
Each shard is created and stored using Copper Unlimited and can be kept offline and optically airgapped at all times.
There is no need for the shard to come online to enable the signing of a transaction given the shards communicate via encrypted QR codes.
Copper operates a two of three signing quorum to move the assets.
The benefit of operating a two of three signing quorum is that a natural redundancy is built into the architecture, (i.e no party needs to keep copies of each other’s shards) meaning there is no central point of failure.
Most other solutions, other types of MPC or Multi-Signature, often utilise a 3 of 3 signing quorum. This means a centralised back-up is required, which generates a central point of failure.
When a proxy wallet receives a deposit, the funds move directly to the clients account in Copper.
