Why CryptoPunks are a unique📚 The CryptoPunks contracts (V1 and V2) predate the ERC-721 standard and operate differently from modern NFTs. The contract stores a SHA-256 hash of a single image containing all 10,000 Punks, with each token representing the coordinates of a specific Punk in that image. Unlike most modern NFTs, CryptoPunks do not rely on IPFS or other off-chain storage services, avoiding risks related to dependency on external infrastructure. Majority of NFT collections are using IPFS/centralized solutions, and they may face issues in future, such as data inaccessibility, long term maintenance costs, centralized points of failure or data corruption/lost. CryptoPunks mitigate these issues by storing the hash of the composite image directly on-chain, ensuring that is preserved and always verifiable as long as the Ethereum blockchain exists. The actual rendering of the image may rely on external tools, but the hash guarantees immutability and permanence, unlike off-chain systems where data can vanish. Study CryptoPunks
