Welcome to io.finnet’s exploration of trustless Multi-Party Computation (tMPC), a groundbreaking technology powering our platform. Whether you are a small or large enterprise, understanding digital asset security is key to safeguarding your investments.

The Foundation: Cryptography in the Digital Age

‍

Cryptography is the bedrock of digital security, ensuring that your assets, whether Bitcoin, Ethereum, or emerging tokens like TAO, remain confidential and accessible only to you. It relies on private keys to sign transactions on blockchains. However, the challenge has always been safeguarding these keys. A single breach can lead to total loss, making traditional key management a high-stakes game.

‍

What is Multi-Party Computation (MPC)?

‍

MPC is a cryptographic technique where multiple parties collaborate to compute a result (like a transaction signature) without revealing their individual inputs. Imagine three colleagues calculating the average salary without disclosing their earnings, MPC makes this possible securely. Originating in the 1980s, MPC evolved through the 2000s with efficient protocols and gained traction in the 2010s as digital asset custodians sought alternatives to vulnerable single-key systems. Today, it’s a cornerstone across finance, healthcare, and beyond.

Why Trustless MPC (tMPC) is a Game-Changer

‍

At io.finnet, we’ve taken MPC further with tMPC, a trustless approach that eliminates reliance on any central authority, including ourselves. Here’s how it works and why it matters:

• Distributed Key Generation: Unlike splitting a pre-existing key, tMPC generates unique key shares locally on your device (e.g., via secure enclaves on iOS). No full private key ever exists, reducing the attack surface.
• Weighted Signing Authority: Assign varying signing powers (e.g., 2 shares to a compliance officer, 4 to a CEO) to align with your organization’s hierarchy, ensuring critical decisions require consensus.
• Threshold Security: A predefined number of signers (e.g., 8 out of 12 shares) must approve a transaction, preventing unilateral control.
• Privacy Preservation: Each signer holds only their share, ensuring no one can deduce others’ identities or reconstruct the full key.
• Collaborative Signing: Signers jointly compute a signature via an MPC protocol, compatible with blockchains, without ever assembling a complete key.
• Gas Optimization: tMPC produces a single signature, minimizing gas costs for high-frequency transactions—a boon for DeFi and trading.
• Enhanced Security: By eliminating a single point of failure, tMPC ensures assets remain safe even if some shares are compromised, as long as the threshold isn’t met.
• Flexibility: Adjust participants and thresholds dynamically to suit evolving business needs.

Advanced Features of tMPC

• True Trustlessness: Signers retain full control of their shares, with end-to-end encrypted communication during ceremonies, ensuring io.finnet never holds keys.
• Orchestration Role: We coordinate signing and key generation, maintaining security without custody.
• Signer Independence: Signers verify transaction details (e.g., via full-resolution screens), preventing blind signing and tampering.
• Disaster Recovery: If io.finnet is unavailable, an offline, open-source tool lets signers pool encrypted backups and passphrases to recover funds.
• Full Segregation of Vaults: tMPC ensures each vault has its own unique private key, allowing the same devices to securely manage multiple vaults, different devices to handle distinct vaults, and independent disaster recovery methods for each vault. This complete segregation of client funds eliminates cross-vault vulnerabilities, enhancing security and enabling organizations to tailor their asset management strategies with confidence.
• Mobile & Virtual Signers: Leverage iOS, macOS & Android secure enclaves for hardware-enforced security or Intel® SGX for server-side policy execution.
• Blockaid Transaction Simulation: Screens for malicious activity, adding an extra layer of defense during transaction orchestration.

Overcoming Traditional Limitations

‍

Traditional key management—cold storage, hardware wallets, or hot wallets—comes with trade-offs: slow access, physical vulnerabilities, or online risks. tMPC decentralizes this process, offering secure, efficient transfers without these drawbacks. It evolves digital asset security from custodial solutions and multi-signature wallets to a third-generation, trustless standard.
