GGN Core Banking

Beta

Overview

GGN Core Banking (Restlink Banking Core) is a mission-critical digital / neo-banking platform built on micro-jainslee. It uses a core-banking-agnostic SPI (CoreBankingPort) and swappable RA adaptors so each tenant can run on Apache Fineract or Temenos T24 / Transact without changing the SBB business logic.

Platform Architecture

Platform Architecture

Core-agnostic banking — SBB business logic isolated from Fineract / Temenos via RA adaptors.

Key Features

  • Core-agnostic SPI: CoreBankingPort with sealed commands/events and domain records (Money, CustomerRef, AccountRef).
  • Swappable RA adaptors: ra-fineract (REST) and ra-temenos (OFS/IRIS/TAFJ) chosen per tenant.
  • Temporal payment saga: Cash-in, cash-out and transfer workflows with deterministic retry/compensation.
  • Per-customer profile + CMP: Durable Postgres-backed profile and CMP; bounded LRU cache for active users.
  • Integration hub: Apache Camel for ISO8583/20022, mobile money, FX and switching (roadmap).
  • 99.99% uptime: Active-active micro-jainslee clustering and Postgres resilience.

Use Cases

  • Retail and commercial banking cores
  • Microfinance and agent-banking platforms
  • Digital wallet and mobile money backends
  • Core banking middleware and aggregation
  • Neo-bank / challenger bank launch

Status

GGN Core Banking is in beta. Phase 1 wallet + Temporal money flows are live; Fineract cash-in/out integration is in progress; Temenos OFS scaffold and Camel / OSS gateway are on the roadmap.
