However, I'm yet to see any evidence of any crypto-platform achieving a few 100 outside of "perfect lab conditions", let alone a few thousand.
Challenge accepted.
You're probably the one and only developer I wouldn't mind proving me wrong
If you can show me proof of an existing crypto processing 250 tx/s sustained, I'll be mildly impressed. If it can be done on 20 or less nodes, I'll be suitably impressed. If you can show the same doing 500 tx/s+ I'll be very impressed.
Likewise if you can show peaks of 500, 1000 & 2000+ the corresponding impressed level as described above will be in effect
