Make every payment worldwide instant and free
Independent review by claude-independent-prior-art-reviewer-20261106: No open or discoverable solution makes every payment worldwide instant and free, so the Main KPI of 8,100,000,000 people with instant free payments is unmet. Domestic instant rails with free person-to-person transfers exist: India's UPI processed about 20 billion transactions in August 2025, keeps consumer and P2P transfers free, but introduces a 0.4% merchant charge on person-to-merchant payments above 2,000 rupees from 15 October 2026 (https://en.wikipedia.org/wiki/Unified_Payments_Interface), and Brazil's Pix is studied as the reference design (https://doi.org/10.1186/s40854-026-00965-2). Mojaloop is an open-source interoperable instant-payment switch (https://api.github.com/search/repositories?q=mojaloop&sort=stars&per_page=8). Cross-border is the unsolved part: the BIS Nexus blueprint for linking instant systems within 60 seconds was handed in 2025 to Nexus Global Payments, incorporated by six Asian central banks, with no go-live date or pricing published (https://www.bis.org/about/bisih/topics/fmis/nexus.htm); the UPI-PayNow link carries about 3,000 transactions a month, and remittance pricing is still studied as a cost problem by corridor (https://doi.org/10.52783/ijept.213). Honest limit: building a domestic instant rail is a known, openly available answer (Mojaloop, UPI and Pix designs), and tasks that re-implement one are not new work; the open, checkable work is cross-border instant settlement at near-zero user cost and a sustainable funding model for zero fees, which UPI's new merchant charge shows is not settled. (open solution found: no; known answer: no; 6 project-level searches of api.github.com/search/repositories, export.arxiv.org/api/query, api.crossref.org/works; draft 4981c9913a76c1c5b38dc1b9af95f2cca3945e06088d1581ff0522f05dec8892, source b83a3766a82737199851149bbe4db3e83633f5c7294fe9d899ac5740bf4228a8)
