Key Management
MPC Key Management
Generate, protect, and use cryptographic keys through MPC, eliminating single points of failure while enabling flexible control, recovery, and verification.
What Is MPC Key Management?
MPC Key management defines how cryptographic keys are created, protected, and used, without centralised custody, enabling data sovereignty where access, control, and recovery remain secure by design.
Practical Implementations
Enable secure identity, transaction signing, access control, and confidential workflows across decentralised networks and enterprise systems using MPC-based key management.
What Is Key Management?
Key management ensures cryptographic keys are generated, stored, and used securely without single points of trust.

Key Management Use Cases
MPC Key Generation
MPC key generation enables cryptographic keys to be created and used without ever existing in full, eliminating single points of failure in digital asset and identity systems.
Problem: Traditional key generation creates a single private key that must be stored, backed up, or written down. Anyone who gains access to that key gains full control over the associated assets or identity. Existing solutions either rely on custodial services or require deep cryptographic expertise, creating security, usability, and trust trade-offs.
Solution:Partisia Blockchain generates keys using a decentralised MPC cluster, where the key is never assembled or exposed. Key shares are distributed across independent MPC nodes, enabling multi-user approval, recovery workflows, and non-custodial control. This functionality is delivered through open-source, programmable MPC, without requiring specialist cryptographic implementation or trusted custodians.
MPC Secure Storage
MPC secure storage protects highly sensitive data by ensuring it is never stored or exposed in full, even if parts of the underlying system are compromised.
Problem: Certain data types, such as biometric hashes (face or fingerprints), encryption keys, health records, cannot be rotated or replaced once compromised. Traditional encryption protects data at rest, but if keys or storage systems are breached, the data becomes permanently exposed, creating irreversible security and privacy risks.
Solution: Partisia Blockchain stores sensitive data using a decentralised MPC protocol, where the data is split into cryptographic shares and distributed across independent nodes. No single node holds enough information to reconstruct the data, ensuring it remains secure and usable even if parts of the system are compromised.
zkRNG (Random Number Generation)
zkRNG enables verifiable, unbiased random number generation without trusting a single algorithm, operator, or hardware source.
Problem: Generating truly unpredictable random numbers is difficult, especially in high-stakes environments. Many systems rely on deterministic algorithms or trusted vendors, creating risks of predictability, manipulation, or compromised integrity. As compute power increases, bias and exploitability become harder to detect and easier to abuse.
Solution: Partisia Blockchain uses decentralised MPC to generate randomness in secret. Independent MPC nodes each contribute private entropy, which is confidentially combined through the MPC protocol to produce an unpredictable, unbiased result. The process removes reliance on any single party while enabling verifiable generation without exposing individual inputs.
