Those are old numbers. According to the VISA Annual Report from 2017, the VISA network does ~3500 transactions per second (tps) (average) [0] and a "FactSheet" put out by VISA claims 65,000 peak tps [1].
And AliPay had ~325,000 peak tps according to their 2017 annual report [2].
I wouldn't trust the Alipay stats. The aliexpress 11.11 pre-sale BS forces everyone's purchases to be ordered in advance for two weeks at one time of the year. The actual sales are often as little as 1% discount. They then claim insane one day sales figures when they batch process all those transactions through Alipay.
If you were able to quickly find these numbers, and if those "academics" can't get latest facts right...
Good golly, articles like this drive me nuts. False future hyped promise.
My team shipped over the last 4 years, and our system has already done ~3300 transactions per second (tps) (average) in production on $99 worth of P2P hardware.
Internet Archive, top 300 global site, is also running it in production as well. I just gave a talk there about how to do distributed load testing in a decentralized network: https://youtu.be/hYH2Z1A0x3c?t=3635
