Multi-party computation (MPC)

Advanced threshold signature schemes with distributed key generation for maximum security and operational efficiency.

Technical Features

Multi-party computation

CustodiFi's MPC implementation uses state-of-the-art threshold signature schemes to eliminate single points of failure while maintaining operational efficiency. Private keys are mathematically split across multiple parties, ensuring no single entity ever has access to the complete key.

Threshold Signatures

Support for 2-of-3 and 3-of-5 configurations with customizable thresholds

Distributed Key Generation

Keys are generated collaboratively without any party learning the complete secret

Proactive Secret Sharing

Automatic key refresh to maintain security even if some parties are compromised

Hardware Security Modules

HSM integration for enhanced security and compliance

Multi-Network Support

Unified MPC across Bitcoin, Ethereum, Solana, and 50+ other networks

Zero-Knowledge Proofs

Cryptographic proofs that operations are valid without revealing sensitive data

FREQUENTLY ASKED QUESTIONS

Technical Deep Dive: Your Questions Answere

How does MPC compare to traditional multi-signature?

MPC provides mathematical security guarantees where multi-sig relies on trust. With MPC, no single party ever has access to the complete key, even during signing operations.

What happens if one of the MPC parties goes offline?

Our MPC implementation is designed for fault tolerance. As long as the threshold number of parties is available, operations continue normally. We also support automatic failover and recovery.

How do you ensure the security of the MPC implementation?

Our MPC implementation undergoes regular security audits by leading firms. We use proven cryptographic protocols and maintain formal security proofs for all operations.

Can MPC be integrated with existing infrastructure?

Yes, our MPC solution is designed for seamless integration. We provide comprehensive APIs, SDKs, and documentation to make integration straightforward.

What compliance features does MPC provide?

MPC operations generate comprehensive audit trails that satisfy regulatory requirements. All operations are logged with cryptographic proofs of validity.
