# Launching DevNet6 – CognitiveLevel, Final Pillars & Testnet Strategy

**DevNet6** is launching with Cortensor’s **first full-stack deployment**, marking the shift from modular experimentation to cohesive protocol validation. It brings together adaptive miner coordination, enforced payments, dual testnets, and the infrastructure to scale into a permissionless execution layer.

***

### CognitiveLevel: Adaptive Intelligence Layer

**Status:** Launching with DevNet6\
**Purpose:** Dynamically classify miner nodes based on:

* Historical performance
* Token throughput
* Inference quality (ack → precommit → commit)

**Enables:**

* Tiered prompt complexity and task allocation by node capability
* Hardware-aware job routing (from Raspberry Pi → H100)
* Support for future multi-model deployment

**Significance:**\
Moves Cortensor beyond “one-model-fits-all” toward adaptive, scalable AI coordination across a heterogeneous, decentralized network.

***

### DevNet6 Objectives: Full-Stack Validation & Hardening

Core priorities for DevNet6:

* Validate prompt compatibility across Cognitive Levels
* Refine task scoring logic (ack → precommit → commit weighting)
* Enforce `SessionPayment` credit and payout mechanics
* Iterate miner/oracle sync to keep CognitiveLevel accurate
* Improve UI/dashboard for session funding and payment visibility
* Begin validator set planning for oracle rotation
* Explore practical privacy integrations:
  * Session-based authentication
  * Diffie-Hellman key exchange
  * Optional Trusted Execution Environment (TEE) support

***

### Dual-Testnet Rollout (Post-DevNet6)

#### 1. **Arbitrum Sepolia Testnet**

* Stable environment for app developers
* Used for validating session workflows
* Primary testnet for public onboarding and dApp integration

#### 2. **Experimental L3 Rollup**

A dedicated rollup for modeling Cortensor’s gas/token economy using a **staged rollout**:

**Phase 1: ETH-as-Gas (DevNet6 & Testnet Phase)**

* Default gas token during testing
* Enables rapid iteration with familiar infra
* No need for COR token faucet mechanics

**Phase 2: COR-as-Gas (Post-Mainnet Upgrade)**

* Enables COR to become true fuel for computation
* Creates circular economic flow between users, miners, and governance
* Provides deflationary pressure via gas usage
* Activated via rollup config without contract redeploys

> **DevNet6 tests infrastructure. Testnet validates coordination. Mainnet unlocks economic flywheel.**

***

### Model Support Roadmap

Hardware-aware classification enables multi-model routing starting in DevNet6.

**Initial Model Targets:**

* DeepSeek
* Qwen
* Other open-weight LLMs under review

**Next Steps:**

* Prompt tuning and miner benchmarking
* Integration at task level
* Gradual scaling across network

***

### Hackathons, Tooling & Ecosystem Growth

DevNet6 begins a continuous cycle of **internal and external hackathons** to mature the ecosystem:

#### Internal Hackathons

* Target early tooling, dashboards, bots, SDK flows
* Drive improvements in observability, job tracing, and session quality

#### External Hackathons (Post or During DevNet6)

* Will expand as E2E stack stabilizes
* Focus on agent apps, frontends, wallets, and composable use cases
* Rewards and grants tied to long-term utility

**Community Tools & Collaboration:**

* [Cortensor Community Projects GitHub](https://github.com/cortensor/community-projects)

### What Comes After DevNet6

#### DevNet7

* Final internal environment
* Dataset expansion, coordination under pressure, and validator refinement

#### Public Testnet

* Used to evaluate live network behavior and validator performance
* Will guide validator set selection and final mainnet adjustments

#### Mainnet Launch

* Will follow successful public Testnet
* COR-as-Gas and full token utility enabled
* Validator set, reward logic, and governance modules activated
