Planetary Settlement Grid (PSG)

Overview

The PSG forms the physical + logical backbone of DBIS settlement worldwide. It is globally distributed, quantum-secure, fault-tolerant at planetary scale, and multi-asset aware.

Components

Geo-Redundant Sovereign Nodes

Each SCB has at least 3 nodes across different regions
PQ-encrypted replication links

DBIS Master Grid

Global ledger orchestrator
Settlement finality controller
Quantum-grade consensus engine

Supra-Sovereign Relay Hubs (SSR-Hubs)

Route traffic across continents
Optimize latency and FX routing
Provide fallback paths during crises

Settlement Epochs

PSG commits global settlement every:

1 second for CBDC + fiat
5 seconds for commodities
10 seconds for securities

Epoch commit rule:

PSG_State = HASH(SCB_blocks + CBDC_tx + Commodity_tx + Security_tx)
