Protocol Layering

This section breaks down the foundational components that form the Silensio technology stack:

🧠 ZK Engine

At the heart of Silensio is its zero-knowledge proof system. We support industry-leading ZK engines such as:

• Circom: A circuit compiler ideal for creating custom zkSNARK circuits.

• Halo2: Developed by the Electric Coin Company (Zcash), offering recursive proof capabilities.

• Plonk: A universal SNARK system that allows quick verification and flexibility in proof composition.

These engines allow Silensio to generate cryptographic proofs that enable users to prove claims (e.g., identity, balance, order execution) without revealing any underlying data.

🧱 Smart Contract Infrastructure

Silensio integrates with EVM-compatible chains using smart contracts written in Solidity. Key features include:

• zkRollup Compatibility: Support for zkSync, Scroll, Polygon zkEVM, and more, enabling high-throughput, low-cost interactions.

• Customizable Privacy Primitives: Developers can deploy privacy-enhanced contracts such as mixers, verifiable identity systems, or zkSwap logic.

Smart contracts serve as the on-chain logic that ties ZK proofs to enforceable and verifiable outcomes.

📡 Communication Layer

Silensio includes a secure peer-to-peer communication system powered by:

• Mixnet Routing: Inspired by Tor and Nym, this layer anonymizes metadata and hides the origin/destination of messages.

• libp2p: The decentralized networking library used by IPFS and Ethereum 2.0, allowing encrypted and multiplexed transport.

This layer powers SilenMesh, Silensio’s anonymous messaging stack—enabling censorship-resistant, zero-trace communications.

👤 Identity Layer

Privacy doesn't mean lack of identity—it means selective disclosure. Silensio enables this through:

• zkLogin: Users can prove ownership of social logins (e.g., GitHub, Twitter, email) without exposing account info.

• DIDs (Decentralized Identifiers): Self-sovereign identity standards allowing users to issue and verify credentials.

• Verifiable Credentials: Standards-compliant proofs of roles, qualifications, and access levels—provable via ZK.

This layer enables features such as anonymous DAO voting, age verification, or credential-based access to services.

💻 Interface Layer

Built with developers in mind, the Silensio interface layer provides the tools and UX to integrate privacy across any application:

• Next.js & Tailwind: For building lightweight, fast, and responsive front-ends.

• SDKs: JavaScript and TypeScript SDKs that let developers call ZK functions, handle credential proofs, and route private messages.

• REST APIs & GraphQL: Interfaces for interacting with Silensio services in both Web2 and Web3 apps.

This layer empowers dApp developers, wallet builders, DAO tooling projects, and AI platform creators to easily add privacy without starting from scratch.
