# Article IV: Blockchain Architecture

**Section 1: Architectural Overview**

The Gnodi Blockchain consists of coordinated technical and governance components. These components may include validators, Delphi Nodes, applications, governance tools, Treasury infrastructure, and supporting services. Each component must be defined and operated consistently with this Charter and any applicable technical architecture specifications adopted by governance.

**Section 2: Validator Layer**

The validator layer is responsible for core blockchain security, consensus, block production, and\
transaction validation. Validators shall operate in accordance with the technical rules, staking\
requirements, slashing rules, validator eligibility standards, and network security requirements approved by governance or established in applicable technical specifications.

**Section 3: Delphi Node Layer**

The Delphi Node layer supports utility and application-level functions for the Gnodi Blockchain\
ecosystem. Delphi Nodes may perform authentication, validation, Proof-of-Impact verification, activity validation, application support, distribution calculations, or other functions approved by governance.

**Section 4: Applications**

Applications are user-facing or enterprise-facing software products, services, interfaces, protocols,\
platforms, or integrations that interact with the Gnodi Blockchain. Applications are not themselves the\
Gnodi Blockchain unless expressly authorized as protocol-level components through governance.

**Section 5: DAO Governance Layer**

The DAO governance layer consists of eligible governance participants acting through the Governance Portal and related governance processes. The DAO governs the Gnodi Blockchain through proposals, voting, approval thresholds, and amendment procedures described in this Charter.

**Section 6: Service Provider Layer**

Service Providers may support the Gnodi Blockchain through administrative, technical, development,\
infrastructure, treasury, commercial, compliance, or operational services. A Service Provider is not the DAO, does not own the Gnodi Blockchain, and does not control the Treasury unless expressly authorized and limited by governance.
