TreSori MPC

What Tresori MPC Is

Tresori MPC is a secure, enterprise-grade wallet security model built on Multi-Party Computation (MPC) and Threshold Signature Schemes (TSS). It allows applications to sign blockchain transactions without ever creating, storing, or exposing a complete private key not on the server, not on the client, not anywhere.

Instead of one private key, Tresori distributes key shares across multiple independent parties. A transaction is signed collaboratively, and only the final signature is produced never the key itself.

Think of it like a nuclear launch system: no single person has the full code, yet actions can still be authorized safely.

Why Tresori Uses MPC

Traditional Model	Risk
Single private key	Total loss if compromised
Seed phrases	User error, phishing, loss
Central custody	Single point of failure
Browser extensions	Malware & injection attacks

At a high level, Tresori MPC secures your wallet and transactions using three invisible cryptographic layers. As a user, you never see private keys, seed phrases, or complex security steps yet your assets remain protected by some of the strongest cryptography available.

A. Key Sharding (Distributed Key Generation – DKG)

When your wallet is created, Tresori never generates a complete private key at any point. Instead of creating one sensitive key that could be stolen or lost, Tresori mathematically divides it into multiple secure fragments called key shares.

Example:

Private Key → Split into (K1, K2, K3)

B. Threshold Policy (T-of-N Model)

Tresori uses a threshold approval model, meaning only a predefined number of key shares must cooperate to sign a transaction. This adds flexibility, resilience, and strong governance without making things harder for you.

C. Distributed Signing (MPC-TSS)

When you initiate a transaction sending tokens, interacting with a smart contract, or performing any blockchain action your wallet signs it securely without ever reconstructing the private key.

When a transaction is initiated:

1. Each party computes a partial signature

2. Partial signatures are combined

3. A valid blockchain signature is produced

4. The private key never exists
