Technical Architecture

Component	Role	Security Features
Ethereum Node	Smart contract execution, P2P settlements	Rootless Docker, AppArmor, nftables port isolation
Node.js API	Transaction API, KYC/AML checks	JWT auth, rate limiting, SELinux httpd_t
PostgreSQL	Wallet storage, audit logs	LUKS-encrypted volumes, row-level security
AI Fraud Detector	Real-time anomaly scanning	Isolation Forest ML on transaction patterns

                Security Foundation
                Kernel Isolation: SELinux confines blockchain processes
Networking: SDN micro-segments services
Storage: Ceph with LUKS encryption
Compliance: Built-in audit trails for GDPR and SOC 2

Deploy Custom Stack

Create /templates/stacks/ethereum-fintech.yml:

version: '3.8'
services:
  ethereum:
    image: ethereum/client-go:latest
    command: --http --http.addr 0.0.0.0 --http.port 8545
    volumes:
      - ceph-blockchain:/data
    ports:
      - "8545:8545"

  api:
    image: node:20-alpine
    working_dir: /app
    volumes:
      - ./fintech-api:/app
    ports:
      - "3000:3000"
    environment:
      - ETHEREUM_RPC=http://ethereum:8545
      - DB_URL=postgres://user:pass@db:5432/fintech
    command: npm start

  db:
    image: postgres:16-alpine
    environment:
      POSTGRES_DB: fintech
      POSTGRES_PASSWORD: securepass
    volumes:
