Overview

TMC is a modular co-processor and rollup stack enabling verifiable Fully Homomorphic Encryption (FHE). It unlocks privacy-preserving, massively parallel execution of computations for both Web2 and Web3 applications.

By leveraging FHE, advanced modular rollup designs, and parallelism in computational proofs within a trustless computing layer, TMC enables secure, near real-time computations on both public and private on-chain states while preserving composability and interoperability.

Key Features

• Modular Architecture: Highly adaptable zk-rollup framework integrating state-of-the-art privacy-preserving solutions like FHE and Zero-Knowledge Proofs (ZKPs).

• Module System Interface:

  • Supports both stateless and stateful modules, enhancing composability.
  • Incorporates FHE-powered modules using the TFHE-rs library for computations on encrypted data.

• Data Availability Interface:

  • Integrates with various data availability solutions (e.g., Celestia, Avail).
  • Compatible with mainstream Layer 1 blockchains for settlement layers.

• zkVM Interface:

  • Supports optimistic, zero-knowledge, and verifiable FHE virtual machines.
  • Compatible with various zkVMs, including RISC Zero and SP1.
  • Produces succinct verifiable proofs for transaction executions.

• Threshold Service Network:

  • Secure key management for FHE keys.
  • Robust FHE key generation and threshold decryption using MPC protocols.

Use Cases

• DeFi:

  • Dark Pools: Enable private large trades to reduce market impact.
  • Blind Auctions: Conduct auctions with hidden bids to prevent manipulation.
  • MEV-Resistant DEXs: Build exchanges where transactions can't be front-run.
  • Enhanced Privacy: Improve transaction confidentiality beyond current blockchain capabilities.

• Social Applications:

  • Efficient Identity Verification: Perform identity checks without constant off-chain data retrieval.
  • Privacy-Preserving Interactions: Ensure all user interactions remain private.

• Gaming:

  • Real-Time Response: Enable near real-time transaction responses in distributed systems.
  • Secure Interactions: Operate nodes in a "dark forest" state for enhanced security.
  • Asset Integration: Flexible combination of DeFi and GameFi assets.
  • Flexible Gas Fees: Implement dynamic gas fee structures to lower entry barriers.
