Also would be grateful for a non tech explanation of zero knowledge!?!?
What's it about? And why is it or not so good?
Want to work out what it has over XC tech!
Zero-knowledge proofs allow you to prove to someone that you've paid them without revealing your address.
It's a powerful technology, but:
- it's not decentralised because a server is required for one stage of the process
- it bloats enormously.
- it's new, untested, and therefore potentially insecure cryptography.
So it's not really implementable, practically speaking, at this stage.
Furthermore it's not a flexible technology. It's a total blackout. This is not particularly useful in the real world. For example:
- you buy something and need to prove to the seller that you've paid and not somebody else
- if the seller denies having received payment, you'll need to prove to the cops (or something) that you paid
- ZK doesn't conceal the amount sent, so if you donate money to a charity or political campaign, you won't be able to conceal that the charity received x amount from someone.
ZK is, ironically, only useful between people who trust each other. :-)
Thanks for the explanation!
Not sure the hype about zero knowledge? If it has so many weaknesses.
. Anyone ?
