Sovereign-ZK

A theoretical concept framework exploring privacy-preserving cross-border GPU compute using Zero-Knowledge Verifiable Computation (ZK-VC) and Confidential Computing (CC). Developed by Chidiebere V. Christopher.

Sovereign-ZK proposes a two-tier architecture for institutions to offload heavy deep learning workloads to remote Confidential GPUs. It explores protecting plain-text data from remote software adversaries using hardware TEEs, while maintaining computational integrity via probabilistic audits.

v0.3.0+ Architecture Revamp: The framework has completely shifted from Web3 Smart Contracts to a mathematically rigorous SLA-Backed Probabilistic Audit Model. It uses a Commit-Then-Challenge protocol driven by a public randomness beacon (e.g., drand) to ensure cloud provider accountability via economic deterrence ($S \ge g/q$) without blockchain privacy leaks.

Installation / Upgrade

To upgrade to the SLA Commit-Then-Challenge architecture:

pip install --upgrade sovereign-zk

Quick Start (SLA Probabilistic Architecture)

1. Start the Remote GPU Node (Kenya)

The node continuously listens for new AI compute jobs and outputs cryptographic commitments ($C_y$) for every single inference to bind its behavior.

python -m sovereign_zk.node

2. Submit Data from the Local Client (Nigeria)

On your local machine, use the client SDK to encrypt your data, generate an input commitment ($C_x$), and query the randomness beacon.

python -m sovereign_zk.client

Under the hood, the client script does this:

from sovereign_zk.client import get_drand_beacon

# 1. Encrypt the data and generate Input Commitment
c_x = hashlib.sha256(encrypted_payload + nonce).hexdigest()

# 2. Receive Output Commitment (C_y) from Node
c_y = network.wait_for_commitment()

# 3. Query Public Randomness Beacon (e.g., 1% challenge rate)
beacon_val = get_drand_beacon()
if beacon_val <= 1:
    # 4. Job is challenged! Reveal nonce to Node to generate ZK Proof
    proof = network.challenge_node(nonce)
    verify_proof(proof, c_x, c_y)
else:
    # Accept outcome based on cryptographic economic deterrence
    authorize_fiat_payment()

Economics

Sovereign-ZK uses standard Fiat/SLA contracts. By enforcing a $100\times$ slashing penalty against the cloud provider if they fail a $1%$ cryptographic audit, African researchers achieve world-class AI compute integrity without the overhead of generating ZK proofs for every single transaction.
