v2.1.0 — Quantum-Ready Infrastructure

Sovereign Ethereum.
Quantum-Ready.
CSM Secured.

EtherNode is a sovereign Ethereum node engineered with post-quantum security (ML-KEM-768),
sovereign key management, direct P2P networking via libp2p, and CSM-integrated defense.

Node Architecture

Every layer of EtherNode is engineered for sovereignty, performance, and quantum-era readiness.

Layer 1

Ethereum Execution Engine

Full Ethereum execution layer client compatible with the Shanghai/Capella and Dencun upgrades. Processes blocks, executes EVM bytecode, maintains state.

EVM Compatible
Layer 2

P2P Networking (libp2p)

Direct peer-to-peer connections via libp2p. No central relays. GossipSub for block propagation, Kademlia DHT for peer discovery.

No Central Relay
Layer 3

RocksDB Persistent Storage

High-performance embedded database for blockchain state, transaction history, and account data. Archival node capability with full historical state.

Archival Capable
Layer 4

Sovereign Key Manager

Self-custody key management. Ed25519 key generation, hardware-backed key storage, multi-sig support. Your keys, your custody.

Self-Custody
Layer 5

Post-Quantum Crypto (ML-KEM-768)

FIPS 203-compliant Module-Lattice Key Encapsulation Mechanism. Protects against future quantum attacks on current cryptographic primitives.

FIPS 203
Layer 6

CSM Security Integration

Cosmic Security Mandala threat detection layer. Behavioral monitoring, anomaly detection, real-time alerting on node activity.

Threat Detection

Defense In Depth

EtherNode's security architecture spans from quantum-resistant crypto to behavioral threat detection. Every node is a fortress.

🔐
ML-KEM-768 Post-Quantum Key Encapsulation
NIST FIPS 203-compliant Module-Lattice Key Encapsulation Mechanism. Protects node communication against quantum decryption attacks.
FIPS 203
🔑
Ed25519 Mutual Authentication
All peer connections authenticated via Ed25519 signatures. No unauthenticated messages pass through the P2P layer.

🛡️
CSM Behavioral Threat Detection
Real-time anomaly monitoring on node operations — unusual RPC patterns, abnormal sync behavior, unauthorized state access attempts.
Active Defense
⚙️
Sovereign Key Rotation & Recovery
Automated key rotation policies. Multi-sig recovery paths. No single point of failure for node operator identity.
Key Mgmt
📡
Encrypted P2P Communication
All libp2p connections encrypted with noise protocol. No plaintext gossip. Metadata minimized to prevent traffic analysis.
