user6441: When installing the zcash client for the first time it downlods a bulk of around 900 MiB in zkSNARK parameters. I am wondering: why and what are they exactly used for? Is this a security feature? How to verify the parameters?
What are zkSNARK parameters and how to verify them?

user42445: It's basically a zero knowledge proof that is easy to verify. The parameters are given on the zcash site. you can check it here
