In the Dark Forest, security is a direct trade-off between Latency and Integrity. The OGI Network Handshake is the protocol designed to eliminate the "Shadow Agent" risk, which is the situation where spoofed data leads to bad execution.

For Tier 3 (The Apex) and above, the Handshake provides a definitive Chain of Custody for every governance signal. This transitions the service from a mere Data Feed to a systemic component of your fund's infrastructure.

Pull-based architecture designed for independent searchers and baseline research. All settlements are executed in USDC on Base L2 via the x402 protocol.

Starting at Tier 3, all webhook payloads are signed using **HMAC-SHA256**. The signature is sent in the X-OGI-Signature header. This ensures absolute integrity between the OGI Nexus and your executioner.

# Institutional Payload Authentication Loop
import hmac
import hashlib

def verify_ogi_payload(payload_bytes, signature, secret):
    expected = hmac.new(secret.encode(), payload_bytes, hashlib.sha256).hexdigest()
    return hmac.compare_digest(expected, signature)

# Response Handling
if verify_ogi_payload(raw_data, sig_header, private_key):
    print("HANDSHAKE VERIFIED: [INTEGRITY_SUCCESS]")

Tier 4+ searchers receive synchronized signals from simultaneous relay nodes (e.g., NY and LDN). To protect your capital from redundant executions, we implement a **One Cancels Other (OCO)** telemetry schema. This acts as a real-time **Performance Audit** of the global Nexus.

Institutional searchers use the latency audit data to optimize their own internal heuristic routing and prove dual-ping delivery to stakeholders.
