Specify the bypass parameters for Zapret binary.
|

There are no universal parameters as they vary between different networks, so you'll have to find them yourself.

|

This can be done by running the `blockcheck` binary from zapret package, i.e. `nix-shell -p zapret --command blockcheck`.
|

It'll try different params and then tell you which params are working for your network.
