Can blockchain solve the provenance problem in antiques and collectables?

Back to Insights

Antiquorum's most talked-about sale was Gandhi's watch, which sold in March 2009 for $1.8 million. The watch itself was worth approximately $50. The difference between those two numbers is provenance: the documented, verified, trusted chain of custody that connects the object to its history and, through that history, to its value. The antiques and collectables market runs entirely on provenance, and provenance is the thing it is worst at producing reliably.

An estimated $6 billion of fraudulent activity moves through the global art market every year, with 80% attributable to forgery. Online sales account for around 8% of the total market. The Antiques Trade Gazette's readership is 83% over 55, with 75% making the majority of their purchases offline, in person or by telephone. The market is large, the spending is real, 75% of Antiques Trade Gazette readers collectively spend over £1.6 billion a year, but it is built on paper records, expert opinion, and institutional trust that is difficult to establish and easy to abuse.

Blockchain changes the foundation of that trust from consensus of expert opinion to mathematical certainty. That is a significant shift, and it opens the market to a far broader range of participants than the current model allows.

The principle is the same one I spent 18 years applying at HSBC Alternative Investments, where trust between counterparties in the custody chain depended entirely on the quality of the records and the rigour of the reconciliation. The antiques market has the same fundamental problem but fewer of the controls. If blockchain can create a shared, immutable record of custody for a $9bn portfolio of Swiss hedge fund investments, it can do the same for a vintage Rolex or a first edition.

The use case: tokenising collectables

The store-of-value use case for antiques tokenisation is straightforward in principle. A seller documents the provenance of a collectable and provides proof of their own integrity. A price is set relative to the market based on quality, age, and verified history. A buyer reviews the provenance, confirms it is sufficient, and transfers value. The collectable is delivered. At every step, the record is written to an immutable chain that every subsequent buyer can read. No expert intermediary is required to arbitrate authenticity because the chain of custody speaks for itself.

This process repeats across the lifetime of the asset. A buyer is a custodian of a physical antique for only a period. At some point they become the seller, or transfer ownership by inheritance, or commission a restoration that changes the object's condition and therefore its value. New provenance information can emerge decades later. All of these events can be recorded on the blockchain as they happen, creating a living, growing record of an object's history that increases in evidential value over time.

Tokenisation adds a further dimension. Rather than treating a collectable as an indivisible asset that must be bought and sold whole, fractional ownership allows multiple investors to hold a stake in a single piece. A vintage Rolex, a first edition, a significant painting, these become investable assets for a far broader range of participants than the current market reaches. Liquidity increases. Barriers to entry fall. The market that currently serves a wealthy, ageing customer base begins to reach a digitally native generation that wants access to real assets as part of a diversified portfolio.

Protocol: public blockchain and proof of stake

Unlike the hedge fund settlement use case, which requires a private permissioned blockchain to protect sensitive financial data and satisfy regulatory access controls, the antiques provenance use case benefits from a public blockchain. The core challenge here is not data sensitivity but trust: potential buyers are deterred by provenance they cannot independently verify. A public, decentralised blockchain addresses this directly. It removes the middleman from the flow of information, distributes authority away from any single authenticating party, and creates a network where every node has access to the same verified record.

Transaction throughput is not the primary design constraint. Ethereum's 14 transactions per second, which would be wholly inadequate for financial settlement, is entirely sufficient for a market where the priority is proof of provenance rather than speed of exchange. The more significant protocol consideration is consensus mechanism. Proof of work requires substantial computing resource, which is disproportionate to the needs of this use case. Proof of stake addresses this by attributing mining power to the proportion of coins held, limiting resource consumption while maintaining consensus integrity. It also incentivises the key provenance stakeholders by rewarding them with the exchange's coin, aligning their economic interest with the integrity of the network.

A public blockchain with a proof-of-stake protocol lends itself well to a sustainable open-source developer community. Intellectual curiosity and coin rewards for building decentralised applications on the exchange create the incentive structure that keeps a developer community engaged and growing. Platforms like Verisart and Codex, which were already active in 2018 verifying the authenticity of artwork on blockchain, and Biddable, which allowed cryptocurrencies to be used in art auctions, demonstrated that a developer ecosystem for this use case was forming organically.

Network: a paper-based value chain moving to digital

The stakeholder map for antiques and collectables is broader than it first appears. Sellers, auctioneers, valuers, museum workers, restorers, buyers, enthusiasts, shippers, manufacturers, Trading Standards, and HMRC all have legitimate roles in the provenance chain, and all need access appropriate to their function. Write access for those who contribute to the record. Read access for those who verify it. The openness of the public chain means that any buyer, anywhere in the world, can inspect the full provenance history of any asset without requiring permission from any centralised authority.

The existing value chain is heavily paper-based. Converting paper provenance to digital records is a prerequisite for blockchain adoption, and it is not a trivial undertaking. Receipts, handwritten notes, inscriptions, photographs, certificates of authenticity, even Rembrandt's dealer was complaining about his clients' poor record-keeping in the 17th century. These records need to be digitised, verified, and attached to the chain in a form that is both legally admissible and practically usable.

Data storage requires careful design. The public blockchain is not well suited to storing large files directly. A decentralised cloud storage solution such as Storj, which uses client-side encryption and file sharding to store data securely across a peer-to-peer network, addresses this. Critically, Storj supports file deletion, which is necessary for GDPR compliance: the right to erasure applies to personal data stored in connection with provenance records, and any architecture that cannot accommodate deletion creates a regulatory liability. The immutable chain stores the proof of record without storing the regulated personal data directly, and the reference to the off-chain document provides the link that makes the record complete.

Application: reaching a new generation of collectors

The application layer needs to serve two distinct populations who currently barely overlap. The existing market participant base is older, offline-dominant, and transacts through established channels: auction houses, dealers, fairs, and direct relationships. The potential new participant base is digitally native, comfortable with cryptocurrency and fractional ownership, and looking for real asset exposure beyond equities and funds.

The applications built on this exchange would need to answer four questions that buyers and sellers ask repeatedly. Does this object exist as a verified asset on the chain? Who currently owns it? Can the seller prove their identity and right to sell? And has this object ever been flagged as stolen, forged, or disputed? Each question maps to a distinct application function: provenance verification, ownership tracking, identity confirmation, and dispute history. Financial applications handle the currency exchange and wallet infrastructure. Non-financial applications handle the provenance tracking. Together they give any participant, anywhere, a clear and auditable answer to the question that currently depends on expert opinion and institutional reputation.

The governance implications are significant. In the current market, authority rests with the major auction houses, leading dealers, and expert authenticators. They decide what is genuine, what is valuable, and whose opinion matters. A public blockchain redistributes that authority across the network. The chain becomes the record of truth, not the expert. Accountability for provenance shifts from the intermediary to the cryptographic record itself. That is a fundamental change in how authority, decision-making, and accountability operate in this market, and every stakeholder needs to reassess their role against this new model rather than simply digitising the existing one.

Assessment

The antiques and collectables market is well suited to blockchain. The buying and selling process is predictable and repeatable. The assets have long lives with multiple ownership transfers. The stakeholder community is defined and identifiable. The reconciliation of provenance data is currently inconsistent and often opaque. Value transfer includes monetary, appreciative, and reputational dimensions. And the case for an immutable record is stronger here than in almost any other market, because the gap between an object with verified provenance and the same object without it can run to millions of pounds.

The barriers are different from those in financial settlement. There is no incumbent with a dominant business model to protect. There is no sophisticated legacy technology to integrate. The primary challenges are adoption, digitisation of existing paper records, and reaching a new participant base that does not currently engage with the market at all. These are commercial and behavioural challenges, not technical ones.

What blockchain offers this market is the ability to move from a world where provenance is a consensus of expert opinion, fallible, expensive, and frequently absent, to one where it is mathematical, permanent, and accessible to any buyer anywhere. For a market that loses $6 billion a year to fraud and is dominated by participants who are over 55 and declining, that is not a marginal improvement. It is a structural transformation.
