Partial The generative picture from block data is vibe-codeable, but a real inscription requires Bitcoin transaction construction, a full node or reliable indexer, and fee and mempool handling. Those on-chain pieces need specialized blockchain expertise.
What it would actually take: Build a Bitcoin indexer or use an API provider to read block height and hash, a deterministic generative renderer (SVG or canvas seeded by the block hash), and an inscription pipeline (ordinals-style envelope, PSBT construction, and fee estimation). The hard parts are correct on-chain encoding, reliable block data, and the cost and safety of minting, which call for an engineer experienced with Bitcoin.
