Sinisiguro ang kinabukasan ng pagbabangko
gamit ang agentic AI
at post-quantum cryptography.

Open-source payments, post-quantum security, and applied AI for financial services.

Soft natural light over a modern architectural space, representing dependable financial infrastructure.

What I build

Open source para sa kinabukasan ng finance.

Payments

Reading the Emerging-Technology Risk Horizon for Banks in 2026

TL;DR Isang orihinal na pagbasa ng abot-tanaw ng panganib ng umuusbong na teknolohiya para sa mga bangko sa 2026 — personalisadong katalinuhan sa AI, sintetikong krimen sa pananalapi, at nauupraprogramang pananalapi — na may balangkas na senyas-tungo-sa-superbisyon, batay sa Technology Horizon Scan 2026 ng FCA.

The Agentic AI Index for Banks in 2026: Measuring Autonomy

TL;DR Ang Indeks ng mga Sertipikadong Blockchain 2026 ay nagbibigay sa mga bangko ng limang-antas na Capability Maturity Model upang sertipikahan ang pamamahala ng distributed ledger, integridad ng konsenso, kriptograpiya, katiyakan ng smart contract, at obserbabilidad ng awdit laban sa DORA, PFMI ng CPMI-IOSCO, ISO/IEC TC 307, ISO 42001, at Basel III.
