QuantumStack Architecture

QuantumStack architecture is designed to ensure digital sovereignty, full transparency, and decentralization. The system consists of four main layers that work together to create an autonomous and verifiable ecosystem.

Architecture Overview

QuantumStack follows a layered architecture where each layer has well-defined responsibilities.

Communication between layers is done through standardized interfaces, ensuring the system is modular, extensible, and easy to audit.

System Layers

1. Application Layer

The application layer is responsible for the user interface and interaction experience.

  • Dashboard: NFT management, wallets and agent interaction
  • Wallet integration: Support for wallets compatible with the ecosystem
  • Visualization: History, status and usage metrics
  • Configuration: Creation and editing of rules associated with NFTs

2. Execution Layer

The execution layer is where the AI agent processes the rules defined in the NFTs and proposes actions.

  • Rule interpretation: Loads and applies rules defined in NFT metadata
  • Context and decisions: Maintains interaction context and makes decisions aligned with rules
  • Action proposals: Sends proposals to the blockchain layer for validation, never executing directly
  • Communication: Natural interface with the user (chat, commands, etc.)

The agent operates in isolation per NFT: each agent has its own context, and all actions go through on-chain validation before any execution.

3. Blockchain Layer

The blockchain layer is the heart of the system, ensuring sovereignty, ownership, and immutable validation.

  • NFT Contract: Manages NFT ownership and reference to decentralically stored metadata
  • Linked wallets: Each NFT can have an associated wallet that validates actions proposed by the agent
  • Ecosystem token: Native token with distribution and incentive mechanisms
  • Protection and validation: On-chain mechanisms ensure only actions compliant with NFT rules are executed

No action is executed without on-chain validation; NFT rules are the single source of truth.

4. Storage Layer

Decentralized storage holds the complete NFT metadata, off the blockchain.

  • Complete metadata: Rules, agent personality, modules and configurations
  • Decentralization: Data distributed across the network, no single central server dependency
  • Immutability and history: Identifiable and auditable versions
  • Verifiable access: The on-chain hash allows anyone to verify and read the associated metadata

Design Principles

Digital Sovereignty

The NFT is the single source of truth for agent rules.

No backend can modify or ignore these rules. On-chain validation ensures they are always respected.

Full Transparency

Rules are in accessible decentralized storage, and actions are recorded on-chain.

Anyone can verify that the system operates according to the defined rules.

Security by Design

Multiple layers of protection:

  • On-chain validation: Critical rules validated by smart contracts
  • Isolation: Each NFT/agent operates in isolated context
  • Executor only proposes: The agent proposes actions; execution depends on on-chain validation
  • Auditability: Actions and events are publicly auditable

Decentralization

The system does not depend on a single centralized backend.

Any compatible executor can read the NFT rules and operate the agent. Failure of one executor does not compromise ecosystem continuity.

Efficiency

The architecture prioritizes operational efficiency and reduced usage costs, with validations and events designed for scalability and audit.

Contract and service-layer optimizations allow smooth operation even with high interaction volume.

Extensibility

The architecture is designed for extension without changing the core:

  • New modules: Additional capabilities can be integrated in a modular way
  • Multiple executors: Any protocol-compatible executor can operate the agents
  • Contract evolution: Contracts can evolve while maintaining ecosystem compatibility
  • Integrations: The system allows integration with other protocols and services
