Overview

What is Dual?

Dual is a tokenization engine for real-world assets. It provides modular blockchain infrastructure that enables secure digital interactions through a hybrid on-chain/off-chain architecture.

The platform consists of several core services: a Gateway for API routing, an Event Bus for action processing, a Sequencer for batching and ordering, and an Indexer for querying on-chain state.

Architecture Overview

Dual uses an optimistic ZK-rollup architecture. Actions are processed off-chain for speed, batched by the Sequencer, and anchored on-chain as fingerprints with a 4-hour fraud challenge window. Optional ZK proofs provide additional verification.

All user requests are signed using EIP-712 typed data signatures, providing cryptographic proof of intent without requiring on-chain transactions for every action.

Key Primitives

• Organizations, Multi-tenant workspaces with role-based access control
• Wallets, Identity primitive for authentication and ownership
• Templates, Define the structure and properties of tokenized objects
• Objects, Instances of templates representing real-world or digital assets
• Actions, Operations executed on objects via the Event Bus
• Faces, Visual representations attached to templates (images, 3D, web views)

How They Fit Together

The Dual data model flows in a clear hierarchy. An Organization is your workspace. Inside it, you create Templates that define what your assets look like. Objects are instances of those templates, each one a unique tokenized asset owned by a Wallet. Actions are the verbs: transfer, update, redeem. Faces give objects a visual layer so users can see and interact with them.
