Phixius has presented 1 V-Sum technical briefing. George (Nacha) and Peter demo Phixius — Nacha\'s business-focused data-services network for financial institutions, fintechs, and payment networks. Where consumer open banking addresses account holders, Phixius addresses the payment-provider side: exchanging data (ACH account validation, electronic payment information, etc.) between Credentialed Service Providers (CSPs) before a payment hits the rail. Phixius is point-to-point — no centralized storage, no give-to-get model. It combines standardized Nacha APIs with a blockchain/shared-ledger layer used for authentication, audit trail, and rule enforcement. Each request uses an authentication token that is effectively the address of a smart contract between the requesting CSP and responding CSP for that specific purpose. The demo runs two exchange services: an ACH account validation (routing + account → valid/invalid for Nacha), and an Electronic Payment Information exchange where Care-Free Catering at High-Rise Bank subscribes to payment info for Best Spreads at Low-Rise Credit Union — replacing the PDF-form email loop with an authoritative API exchange. A smart-contract subscription fires a notification when Best Spreads adds Zelle to their profile, proving the ongoing-update pattern.
