When your UPI payment is confirmed, how do different financial institutions agree on what happened? That familiar confirmation doesn't mean UPI uses blockchain. The challenge is keeping a trustworthy transaction record when several institutions are involved; each may hold a separate copy, and mismatches take time to resolve. That matters when they reconcile payments or settlements across separate records. Blockchain isn't cryptocurrency. In fintech, its value is a shared, checkable record. Transactions are grouped into blocks, each cryptographically linked to the one before it. Network participants keep copies and check records by shared rules. That makes unexpected changes easier to spot and audit, not impossible. And blockchain isn't automatically faster or cheaper; results depend on how it's used. So, what is blockchain? A shared, connected transaction record-useful when several parties need to check the same history, but not necessary for every fintech service.
