An innovative NFT project used proof-of-work to algorithmically generate and mint non-fungible tokens.

The NFTs were of different rarities and higher rarities were harder to mine. The project provided a slow single-threaded CPU-based JavaScript miner which made mining highly rare and valuable NFTs slow and cumbersome.

We wrote a multi-threaded CPU-based JavaScript miner to speed up the mining process. The project increased the difficulty so we wrote a GPU-based miner to heavily accelerate the mining process. This resulted in our client owning more than half of the rarest NFTs of the project in circulation.

We also wrote an indexer to index the blockchain data of the NFT contract and derived analytics to aid our client in trading and managing the NFTs.
