22B transactions a year mean an average of ~700 QPS for the NPCI switch. Of course the traffic is not uniform, it probably peaks at many times that number, but that still doesn't sound that bad - for comparison, a quick Google tells me Nasdaq TotalView ITCH feed peaks at 100k+ QPS at market open.

22B in the month of June 2026, so 264B extrapolated annually.

Centralized, kyced, private money transaction network. Is this something good?

Yes it is. It's not trying to be new money, it's your money that already works.
