Architecture

How UBL Works

Three interconnected systems translating real-world human behaviour into a language that banks understand and trust.

Pillar 1

Community Trust Identity (CTI)

Every person has a rich social identity in their community. A market trader in Kumasi is known by 200 people. UBL captures this invisible trust and converts it into a portable, verifiable digital credential.

Community Vouching

Vouchers confirm character via USSD or app. Weighted by voucher's own Trust Score.

47 Behavioural Signals

Mobile money, airtime, trade frequency — analysed in real-time by SHIELD AI.

Portable Across All Banks

Your Trust Score belongs to you — not to any one bank. Take it anywhere.

Pillar 2

Micro-Accountability Ledger (MAL)

Every financial act becomes a permanent, auditable record on Hyperledger Fabric blockchain — real history from real behaviour, immutable and tamper-proof.

⛓️

Hyperledger Fabric — enterprise-grade permissioned blockchain. Banks and BoG can audit entries.

🔒

Zero-knowledge privacy — members control what banks see. Full consent management.

📡

Offline-capable — USSD fallback works with zero internet connectivity.

Pillar 3

Bank Plug-in API (BPA)

A single REST API any bank integrates in days. One connection to Africa's most comprehensive alternative trust layer.
