Quantum-SVBFT
with SVCP Selection

Intelligence selects.
Quantum secures.

No other L1 uses this model.

Why Hybrid Consensus?

Most blockchains force one mechanism to do everything:

Choose the leader
Produce the block
Secure finality
Prevent attacks

ArthaChain separates these roles

SVCP = The Brain

Ensures fairness, performance, and decentralization.

Quantum-SVBFT = The Skeleton

Ensures unbreakable finality and security.

This Dual System Gives ArthaChain

Infinite scalability

Sub-second finality

Zero staking

Zero mining wastage

Quantum resistance

Full decentralization

SVCP

AI Selector Layer

Scalable Virtual Consensus Protocol

SVCP is not PoW or PoS.

It is a Proof of Computation + Behavior system powered by AI.

NodeScore: The Heart of SVCP

Every node receives an AI-generated score (0.0 – 1.0)

Device Health

CPU/RAM, stability

Network Quality

Latency, uptime

Storage Reliability

SVDB integrity

Engagement

Vote participation

AI Behavior Score

Patterns, honesty

Weighted Lottery: Leader Selection

Nodes above score threshold become Proposer Candidates

Weighted randomness algorithm selects the leader

Higher NodeScore = Higher probability

1

No rich validator dominance

2

No stake-based corruption

3

No GPU/ASIC advantage

4

Full fairness

A Raspberry Pi with perfect uptime can outperform a malicious supercomputer.

Quantum-SVBFT

Finality Layer

Quantum Secure Verifiable Byzantine Fault Tolerance

Deterministic 3-Phase Commit

PREPARE

Validator checks block validity

Validates PQC signature

Broadcasts PREPARE vote

PRE-COMMIT

Validators confirm +2/3 PREPARE

Broadcast PRE-COMMIT vote

COMMIT

Validators lock the block

Block becomes PERMANENT & IRREVERSIBLE

Absolute finality, not probabilistic like Bitcoin.

Quantum-Resistant Security

Every vote, signature, and consensus message uses:

Dilithium (post-quantum)

ML-DSA

Hybrid Ed25519 + PQC

Even a future quantum computer cannot:

Forge validator signatures

Rewrite history

Steal accounts

Break message authentication

The Brain–Skeleton Pipeline

End-to-end consensus flow

User Transaction

AI Brain – SVCP

Analyze → Score → Select Leader → Parallel Block Build

Skeleton – Quantum-SVBFT

Prepare → Pre-Commit → Commit → FINALITY

State Applied (EVM/WASM)

Entire flow finishes in sub-second time under load.
