{"product_id":"sovereign-compliance-gateway-verifiable-payment-data-residency","title":"Sovereign Compliance Gateway — Verifiable Payment-Data Residency","description":"\u003cp\u003ePure-software middleware that gives Nigerian financial institutions provable, continuously-verifiable compliance with the CBN payment-data-residency mandate — where the operator itself is in the threat model.\u003c\/p\u003e\n\u003cp\u003eBanks already have to localise the data; what they cannot easily do is prove it, continuously, in a form CBN accepts under sanction. That gap is the product. The gateway observes where payment data lives out-of-band — never in the payment path — classifies and cryptographically attests each residency decision, chains those attestations into a tamper-evident RFC 6962 transparency log, and renders the CBN return, such that a regulator can verify any transaction's compliance without trusting the bank or the vendor.\u003c\/p\u003e\n\u003cp\u003eThe trust plane is built so the operator cannot cheat: witnessed N-of-M quorum and threshold co-signing make non-equivocation and history tampering detectable, and a standalone verifier checks every proof against a pinned public key. One vendor-neutral codebase — no bank, cloud, or data format named in the fixed core — serves one institution or fifty through a multi-tenant central plane, with every environment-specific concern behind a pluggable seam.\u003c\/p\u003e\n\u003cp\u003eA security-audited, sanitizer-clean reference implementation of verify-don't-trust residency compliance. Delivered as source, sold outright.\u003cbr\u003e\u003c\/p\u003e","brand":"Vlaander LTD","offers":[{"title":"Default Title","offer_id":47417431720098,"sku":null,"price":450000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/1986\/6018\/files\/poster9.png?v=1783597982","url":"https:\/\/8h2yif-ft.myshopify.com\/products\/sovereign-compliance-gateway-verifiable-payment-data-residency","provider":"Vlaander LTD","version":"1.0","type":"link"}
