Turns out that Zcash swiched to BLS12-381 since https://github.com/zcash/zcash/issues/2502,
thanks to @EdgeDLT for pointing that out. I've checked that our
TestCubicCircuit_EndToEnd_Prod test passes with response file downloaded
from the attestations page of Zcash ceremony, thus I propose to put theirs
attestations link before the link to PPoT, because PPoT attestations contain
outdated links and not all responses can be downloaded.

The example shows that the proover knows the solution of the cubic
equation: y = x^3 + x + 5. The example is constructed for BLS12-381
curve points using Groth-16 prooving algorithm. The example includes
everything that developer needs to start using ZKP on the NEO platform
with Go SDK:
1. The described cubic circuit implementation.
2. The off-chain proof generation with the help of gnark-crypto library.
3. Go verification contract generation and deployment with the help of
NeoGo libraries.
4. The on-chain proof verification for various sets of input data.
