Well basically, you can't as long as you're loading the web page over an insecure connection. If the .asc is loaded over SSL, then verifying the certificate should be sufficient.

Warp does it under the hood (you can do query by example directly on databases). See https://pixelspark.nl/2015/warp-a-query-by-example-analysis-...

This is essentially the idea behind Warp, which can do it on large data sets and databases (https://pixelspark.nl/2015/warp-a-query-by-example-analysis-...)

Author here. I agree with your remark but it simply isn't reality. Another issue is that while users may be aware of the core concepts, they are applied differently between applications (e.g. a relationship in Excel between tables is based on a VLOOKUP formula whereas in SQL it is a JOIN or carthesian product).

I do think data tools can educate users, just like a spreadsheet interface teaches its users about the concept of formulas and relationships between cells.

Why not use some kind of Bitcoin-like proof-of-work system for this? http://pixelspark.nl/public/pow.html has a working demo

This works even better with ES6 generators: https://github.com/pixelspark/dispatch.js
