How to query data

1. Navigate to https://goerli.voyager.online/contract/0x039d1bb4904cef28755c59f081cc88a576ecdf42240fb73dd44ddd003848ce33#readContract

Tasks

• V0: Publish a constant number
• V1: Publish a random number
• V2: Use https://drand.love/
• V3: Make script run continuously
• V4: Write verifier for drand (skipped because https://github.com/0xNonCents/cairo-bls12-381 isn't usable yet. bls12-381 tests take 35 mins to run in native cairo so we attempted to run in oriac but fails here)
• V5: Write a Cairo proxy contract that accepts drand and proxies it to Pontis
• V6: Add a method setPublicKey(publicKey: felt) to contract (put this in contract storage)
• V7: Add a method setAlpha(alpha: felt) and getAlpha() to contract
• V8: Add a method to accept a proof and random number (random number = 1)(assume "verification" of proof is always true)
• V8: Accept setAlpha(alpha: felt) from drand relayer
