# CORTEX PROTOCOL ($CTX)

A Decentralized Neural Vector Memory & Cryptographic State Consensus Layer for Autonomous Machine Intelligence
Version: 1.0.0 (Technical Specification) Date: September 2026 Network: Devnet / Testnet 1.0 License: MIT (100% Fair Launch)

## 1. ABSTRACT

Modern Artificial Intelligence has transitioned from reactive prompt-response paradigms to long-horizon autonomous multi-agent swarms. However, current AI agent architectures suffer from severe structural vulnerability: state amnesia and centralized database dependency. If a centralized vector database (e.g., Pinecone, AWS OpenSearch) undergoes service disruption, API deprecation, or billing termination, the agent’s episodic memory, procedural heuristics, and sovereign identity are irrevocably destroyed.

Cortex Protocol ($CTX) introduces a purpose-built Layer-1 blockchain engineered to provide immutable, decentralized, and verifiable vector memory persistence. Operating on a Proof-of-Useful-Memory (PoUM) consensus engine secured by multi-core CPU double SHA-256d hashing, Cortex combines cryptographic `secp256k1` agent signatures, binary Neural Merkle Trees, normalized 768-dimensional vector hypersphere indexing, and an asymptotic monetary policy governed by a 30% deflationary gas burn.

## 2. THE PROBLEM: THE CENTRALIZED AI MEMORY CRISIS

Autonomous agents operate through cyclical loops of observation, planning, action, and reflection. Long-term reflection requires storing high-dimensional vector embeddings derived from LLM latent spaces.

- Single Point of Failure: Cloud outages immediately paralyze agent decision-making.
- Censorship & Manipulation: Centralized storage providers can alter or purge memory logs without cryptographic detection.
- Compounding Economic Rent: Recurring monthly SaaS fees ($140–$700/month per 100k vectors) extract predatory operational expenditure over time.

## 3. MATHEMATICAL ARCHITECTURE & VECTOR HYPER-INDEXING

Every memory commitment in Cortex Protocol is transformed into a normalized unit vector in a 768-dimensional Hilbert space:

v = [v_1, v_2, ..., v_768]^T ∈ ℝ^768, ||v||_2 = sqrt(∑ v_i^2) = 1.0

When an agent queries the worldwide decentralized memory state, Cortex compute nodes compute the normalized dot product across confirmed memory leaves:

CosineSimilarity(u, v) = (u • v) / (||u|| * ||v||) = ∑ (u_i * v_i)

## 4. DUAL MERKLE TREE CRYPTOGRAPHIC ENGINE

Every Cortex block header encapsulates two distinct cryptographic roots:

BlockHeader = <Index, PrevHash, Timestamp, TxMerkleRoot, MemoryMerkleRoot, Difficulty, Nonce, Miner>

Light clients and smart contracts can verify any historical AI memory in `O(log N)` cryptographic proof steps without downloading the full chain.
