Glossary — The Vocabulary of the Chain

Definitions, in my own terms. Where my usage differs from the market's, trust mine within these pages and the market's outside them.

Signature provenance. The direct, timestamped, cryptographic record of a work's origin — provenance that begins with the maker's own signature rather than any custodian's testimony. The subject of this book.

Classical provenance. The documented history of a work's origin and passage through time: who made it, who owned it, where it traveled, how it survived. Built from deeds of sale, letters, gallery records, museum inventories, and catalogues raisonnés — a paper trail sustained by institutional trust, expert testimony, and human memory. Fragile by nature: a single missing document, forged signature, or shift in expert consensus can fracture the chain. I often refer to it as story provenance, because it is an account that must be retold to survive, where every retelling is a chance to lie. Contrast with signature provenance, which is a record written at the moment of creation, requiring no one's memory to survive.

The time-chain. My name for what the world calls a blockchain, chosen because it names the function rather than the structure: a public, unforgeable sequence of moments — the first record of time that is also made of time.

Mint. The act of signing a work into the ledger; the origin-event. Not a listing, not an upload, not a sale. The moment authorship, identity, and time are bound together in public.

Origin-event. The moment of inscription itself: a specific hand, a specific work, a specific instant, sealed together. Objects can be copied; origin-events cannot, because a moment that has passed can be imitated but never re-entered.

Token. The public instrument of a work's title, custody, and temporal inscription. Not the artwork, and not a mere receipt: the historical and contractual witness to the artwork. See the envelope.

The envelope. My figure for the token: addressed to one person at a time, carrying a message anyone may read, bearing the maker's mark on the front — and, on the back, the postmark of every hand that has carried it. The return address always leads back to the maker.

Smart contract. A program inscribed on the chain that defines how tokens come into being and how they move. For the artist who writes her own, it is the studio: the room, built by her hand, in which her authorship lives.

Wallet / address. The artist's cryptographic identity. Every act signed by an address carries the same verifiable mark, as every stroke of a brush carries the same hand's gesture.

ENS. The Ethereum Name Service: the means by which a human name is bound, publicly and verifiably, to an address. The nameplate on the digital signature. Mine is verdandi.eth.

One-of-one. A work whose token has no siblings: one origin-event, one envelope, one chain of custody. The digital descendant of the unique object, except that its uniqueness lives in time, not space.

Edition. A structured set of tokens descending from a single origin-event. Not several identical objects, but several named places in one moment — the difference between owning one of ten prints and holding one of ten seats at the same table.

Wrapper. A modern token standard enclosing a historical token, carrying it forward without altering its origin — a conservation frame around an old panel. BubbleGum Girl's 2026 ERC-1155 editions, each wrapping one 2018 ART Token, are this book's example.

Lazy minting. The market's practice of deferring the mint until a sale triggers it, creating the record of origin after the work's public life has begun. A fracture, in my terms: the moment of creation and the moment of proof pulled apart, leaving a gap where classical doubt can live again.

Metadata. The token's description of what it witnesses: titles, links, attributes. Where the metadata lives, and under whose control, determines how much of the work's presentation shares the durability of its record.

Custody. Possession after origin. Custody moves; origin never does.

Stewardship. What temporal ownership asks of the collector: guarding the key, tending the media, arranging the succession. The recognition that one is not the owner of the moment but its current address.

Temporal aura. The presence and authority of a work whose origin is knowable: the successor to Benjamin's spatial aura, and the first aura that grows stronger the more widely the work is seen.

Proof layer. What the chain is to the work: not the canvas, not the vault, but the witness. The smallest possible contribution, without which nothing else holds.

Signet. Hardware that holds the signing key within a physical object, requiring the object's presence — and its bearer's — for any act of signature. The oldest authorship technology, returned: the maker's mark that requires the maker's hand.

ERC-20 / ERC-721 / ERC-1155. The three Ethereum token standards that appear in this book. ERC-20 defines fungible tokens — interchangeable units, like currency; my 2018 BubbleGum Girl ART Tokens bent this standard toward editions before a better tool existed. ERC-721, formalized in January 2018, defines the one-of-a-kind token — the standard the world came to call the NFT. ERC-1155, from later in 2018, defines semi-fungible tokens suited to editions, and is the standard in which BubbleGum Girl was completed in 2026.

Block explorer. The public reading room of the chain: a tool through which anyone can look up an address, a contract, or a transaction and read its full recorded history. The instrument of every verification this book invites. Appendix A is a tutorial in its use.

Decentralized storage (IPFS / Arweave). Systems for keeping a work's media outside any single company's servers. IPFS addresses content by its fingerprint and keeps it available so long as someone, somewhere, hosts it; Arweave aims at permanence through an endowment model whose horizon is measured in assumptions as well as decades. Where the body of a work lives; not where its moment lives.

The DAO fork. Ethereum's one act of revision: the public, contested decision of July 2016 to adopt a history in which a notorious theft was undone — leaving the unrevised chain running in parallel to this day. Discussed in Chapter Five as the honest boundary of the word immutable: the chain's past is protected not by physics but by the world-witnessed cost of changing it.
