MPC

Multi-Party Computation allows multiple entities to compute functions over private data without ever exposing the raw inputs.

MPC eliminates the single point of failure by distributing private keys across a decentralized network (nodes). Using cryptographic primitives like Shamir's Secret Sharing or Garbled Circuits, parties compute a joint output while keeping individual data points encrypted. It is the gold standard for institutional digital asset custody: companies like Fireblocks and Coinbase use it to secure billions in AUM without relying on a single hardware security module (HSM). By removing the need for a complete private key to exist in any one memory location, MPC provides a resilient, programmable alternative to traditional multisig setups.
