0xb88d4fde is a blockchain artwork shaped by cryptographic hashes of private messages, subtly recorded when the work is transferred.
This is achieved by using the optional data argument of safeTransferFrom¹ as an invisible channel for human signals.
The collector generates a cryptographic hash of their private message off-chain and transfers the token with this data.
The new hash is combined with the current hashchain state `currentHash = keccak256(currentHash, newHash)`, deterministically reshaping the initial wireframe cube into a unique deformation that carries every past contribution².
Over time, this creates a parallel chain of subtle human signals moving through the system, and the wireframe becomes a visual record of accumulated traces.
The process recalls a palimpsest: manuscripts once scraped and reused, leaving light remnants beneath the new writing.
The resulting form is simple, rigid, and geometric, yet layered with accumulated, intimate traces. To observers, it appears as a minimal cube; to participants, it is a structure shaped by presence.
¹ In ERC721, the standard transfer function safeTransferFrom accepts an optional data (bytes) argument that is often unused.
² Additionally, the contract implements the Sculpture interface from the World Computer Sculpture Garden (0x2a362fF002f7ce62D3468509dD2A4a9f5A8EBBb0), allowing the artwork to be rendered as a standalone sculpture with a transparent background and adaptive color.
