x0r Consensus Puzzle Solution

Puzzle Contract

Contract Address (on the Rinkeby Testnet): 0xD53aAEa35836845f79cB103312f077a1aD4891D6

Contract Etherscan Link: https://rinkeby.etherscan.io/address/0xd53aaea35836845f79cb103312f077a1ad4891d6

PoW (Proof of Work)

The solution to PoW required submitting the correct nonce as input to the "PoW()" function in the puzzle contract. This puzzle simulates mining under PoW consensus where miners need to guess a nonce to mine a block. The correct nonce for PoW was the number of total NFTs I minted in my first two collections = 233.

PoH (Proof of History)

The solution to PoH required submitting the block numbers of the contract creation for my first two collections. This puzzle simulates PoH by involving the historical moments for my NFTs in blockchain history. My first collection was released at block 12258221, and my second collection was at block 12519938.

PoA (Proof of Authority)

The solution to PoA required submitting a transaction FROM a specific Ethereum address. This simulates PoA as only one approved signer/address could solve the puzzle. The address needed to submit a transaction was the address used in my previous scavenger hunt to host the 1/1 NFT treasure (0xCE2B95f7B8D872b9Fb2c403C9D0E4c0C1F6B1dd6). To correctly solve this puzzle, one needed to:

1. Find the seed phrase for this address (located in the solution guide from my first scavenger hunt https://gist.github.com/Blauyourmind/e73e6cd476631c5dd47f2699638a75e2)
2. Log into this account via Metamask and fund it with Rinkeby Test ETH
3. Send a transaction to the puzzle contract function called "PoA()" with your personal address as the input.

SPoRA (Succinct Proofs of Random Access)

The solution to SPoRA required submitting a transaction to the contract with an exact gas price of 1559 GWEI. There were several hints at this number through the pricing of multiple pieces from my collection and the time limit on the Open Edition. Additionally, there was a secret note inside the contract code that told you what to do :)
