Made a zkSNARK “Hello world” program with verifier as a smart-contract on NEAR Protocol.

Gas usage ~ 140Tgas, can be optimized more than that, but I think even this is good.
Now it’s time to implement “proof of set membership” with merkle tree component on a NEAR 😉
@mob any thoughts on this ?)
@mob haven’t found existing bn254/bls12 curve precompiles 🤷🏻♂️ (I’ve seen it in issues in nearcore/sdk, but no pr’s yet)
So I made it as optimal as possible 🤔.
@magamedrasul it’s super cool that even without pre compiled math it fits into gas limit
@magamedrasul may need to add some precompiles or use existing ones to optimize on gas
