Blockchain could make parts of scholarly publishing easier to audit, but it cannot by itself prove that a paper, experiment, reviewer, or author is genuine. The strongest proposal is a consortium ledger shared by publishers, editors, reviewers, and other approved participants. It would timestamp submission, peer-review, and editorial-decision events so that later changes require an agreed governance process. That is a transparency mechanism, not a demonstrated cure for paper mills or fabricated research.
Editors should treat blockchain as one possible layer alongside rich scholarly metadata, identity checks, image-provenance analysis, and coordinated investigations. The 2019 framework that prompted this idea is a design proposal; it reports no real-world trial showing that blockchain reduced fraud.
What the blockchain proposal actually records
The 2019 Frontiers in Blockchain framework proposes a consortium blockchain governed by validated publishers, editors, peer reviewers, and citizen scientists. Smart contracts would map publishing stages to ledger events. A typical record could show when a manuscript was submitted, which journal handled it, when reviewers were invited, when reports were received, when an editor made a decision, and when a correction or retraction was issued.
Because participating organizations share the ledger, a single journal could not silently rewrite the common history. A later investigator might therefore see that a manuscript was submitted simultaneously to several journals, that a review was completed unusually quickly, or that an editorial decision changed after a deadline. The framework presents those possibilities as intended benefits: shared oversight, transparent histories, workflow coordination, and potentially better detection of duplicate submissions, suspicious reviewer practices, and repeated publication of the same results.
#1 Best Overall
Those are proposed capabilities, not measured outcomes. The paper was published in 2019 and does not establish that a production consortium exists today or that its design outperforms current integrity systems. Read the original framework for its governance and smart-contract model: Frontiers in Blockchain (2019).
How a shared publishing ledger could work
- Identity and membership are validated first. Participating publishers and reviewers receive credentials under consortium rules. The ledger is not automatically open to anyone with a wallet; governance determines who may write or verify records.
- An editorial system creates an event. Submission, reviewer invitation, report receipt, decision, revision, publication, correction, and retraction events are signed by the responsible service or person.
- Consensus preserves the event history. Multiple authorized members agree that the event is valid and append it to the shared chain. Altering an old entry would require the consortium’s agreement rather than a private database edit.
- Smart contracts enforce workflow rules. Code could require that a decision follow documented review steps, prevent one identity from accepting conflicting assignments, or alert members when records indicate a concurrent submission.
- Investigators query the history. Editors and integrity officers compare timelines across journals, looking for anomalies that warrant human review.
In practice, the ledger would store hashes, identifiers, timestamps, and workflow metadata rather than a full manuscript or confidential review report. Editorial systems would still hold the documents. That separation reduces exposure of confidential content but means the ledger’s value depends on accurate links to off-chain systems.
What blockchain can prove—and what it cannot
A tamper-resistant record can support the statement “this participant’s system recorded event X at time Y, and the consortium accepted that record.” It cannot support the broader statement “the research is true.” The distinction is central to any fraud-control plan.
| Question | What a ledger may help establish | What still needs other evidence |
|---|---|---|
| Was a manuscript submitted? | A signed timestamp and journal identifier can make later alteration of the workflow history harder. | Whether the uploaded file was complete, original, or accurately represented at submission. |
| Did peer review occur? | Invitation, acceptance, report-receipt, and decision events can be linked in sequence. | Whether the reviewer was qualified, independent, or wrote a substantive report. |
| Is the author real? | A credential can link an action to a registered identity. | Whether the identity belongs to the claimed researcher, and whether that person supplied truthful information. |
| Are the results genuine? | Version and provenance records can show when files or analyses entered the workflow. | Experimental validity, fabricated data, manipulated images, plagiarism, or intentional deception. |
| Was a correction handled? | A visible correction or retraction event can preserve the publication history. | Whether the correction fully addresses the underlying problem and whether all downstream copies were updated. |
This is why a blockchain record does not prove that a paper is genuine. Consensus protects the integrity of accepted entries; it does not independently verify the facts those entries describe. A dishonest or compromised participant could submit false information that is then immutably recorded. Privacy is another constraint: exposing reviewer identities or manuscript relationships may violate confidentiality, data-protection duties, or safety requirements.
Metadata is already a cross-publisher integrity layer
Crossref’s 2024 editorial guidance argues that “The presence and richness of metadata—not the DOI itself—is what carries trust signals across the scholarly record.” A DOI makes an object addressable; it is not a quality certificate. Editors can obtain more useful signals when records include:
- Contributor identifiers that distinguish researchers with similar names.
- Affiliations and their changes over time.
- Funding information and grant relationships.
- Peer-review metadata, where a journal’s policy permits disclosure.
- Links among versions, corrections, expressions of concern, and retractions.
- References and citation links that make unusual citation behavior easier to inspect.
- Crossmark or equivalent update indicators showing whether a reader is viewing the current record.
Rich, machine-readable metadata travels across indexing and repository services, allowing comparison without requiring every organization to join one blockchain. A ledger could complement this infrastructure by preserving workflow events; it should not be pitched as a replacement for complete metadata. See Crossref’s 4 November 2024 guidance for the editor-focused recommendations.
Image provenance catches a different class of fraud
Paper mills and image manipulation often leave visual clues that a workflow ledger cannot detect. A 2024 PLOS ONE study by Cardenuto, Moreira, and Rocha adapts provenance analysis to trace versions of scientific images across articles and group documents with suspiciously reused figures. The approach can help an integrity team find related papers for manual examination.
The study analyzed Retraction Watch data through May 2024. Within the set of retractions that involved image concerns, 20% were categorized as systematic fabrication of suspect papers. In the study’s image-problem dataset, 90% of retractions were biomedical articles. The article also cites a list assembled by Bik and colleagues: as of March 2021 it contained more than 1,300 documents suspected of paper-mill origin, including 370 that had been retracted. These figures describe specific datasets and dates, not all scholarly retractions or all disciplines.
Rank #3
Provenance analysis is a triage tool, not a verdict. The authors explicitly caution that a paper’s inclusion in a suspicious group does not establish misconduct or intent. Editors must inspect source files, methods, authorship, laboratory records, and explanations before deciding on an expression of concern, correction, or retraction. Read the study at PLOS ONE (30 October 2024).
Why paper-mill detection requires early, coordinated action
Paper mills exploit gaps between submission, peer review, production, and post-publication correction. A ledger that only receives a publication event arrives too late. Screening needs to occur while an editor can still pause review or publication, preserve evidence, and contact the authors’ institutions.
The COPE–STM Paper Mills Research Report (June 2022) calls for action across the publication process rather than a single technical fix. A practical workflow combines automated flags with trained staff:

1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute- At submission: check identity consistency, affiliations, funding declarations, duplicate or concurrent submissions, text overlap, and image anomalies.
- Before reviewer assignment: examine suggested reviewers, institutional email domains, conflicts of interest, and unusual reviewer-account relationships.
- During review: retain timestamps and decision history, but investigate implausibly fast reports, repetitive language, or coordinated recommendations.
- Before publication: run image and text screening again, verify references and contributor roles, and ensure that unresolved alerts have an owner.
- After publication: expose corrections and retractions through metadata, link them to the original object, and preserve the reasoned audit trail.
STM’s image-integrity guidance emphasizes screening early enough to investigate before publication where possible. Its page also records that the Image Integrity Working Group was discontinued in March 2026, so it should not be described as an active group. The guidance remains available at STM’s Image Integrity page.

Identity verification helps, but privacy and inclusion set limits
Identity checks can make impersonation and fake-reviewer accounts harder, especially when they connect contributor identifiers, institutional affiliations, and authenticated submission accounts. They also create risks. Researchers may change institutions, work independently, lack a standard identifier, or need confidentiality for safety reasons. A consortium that requires one rigid credential could exclude legitimate contributors.
Hylke Koers, CIO of STM Solutions, summarized the balance in a 13 November 2024 statement: “In a world where scientific integrity is paramount and content becomes increasingly easy to fabricate, we need to develop new ways to establish the veracity of scholarly contributions. Identity verification can provide important safeguards provided that it is implemented in such a way that it does not exclude legitimate contributions and respects researchers’ right for privacy, and does not impose undue barriers.” The full statement appears in STM Publishing News.

Scale explains the urgency, not the solution
The framework cites an estimated 8–9% annual growth in research output from Noorden (2014), a historical estimate that should not be treated as the current rate. It also repeats a Bornmann and Mutz (2015) estimate that global scientific output doubled every nine years after World War II, and a 2016 AJE Scholarly Publishing Report figure of 2 million papers published worldwide in 2015. These dated figures illustrate why manual oversight is under pressure; they are not current counts of annual output.
Bottom line for editors and authors
Blockchain can make a shared publishing process more auditable when multiple organizations agree on governance, identity, data standards, and correction procedures. It may reveal timeline anomalies and preserve evidence for an investigation. It cannot authenticate experiments, certify reviewer competence, or determine intent. The defensible strategy is layered: maintain rich metadata, verify identities proportionately, screen text and images early, coordinate investigations across journals and institutions, and expose corrections and retractions clearly. Treat any blockchain deployment as an auditable workflow experiment whose fraud-reduction effect must be measured, not assumed.
Frequently Asked Questions
Can blockchain stop fake research papers?
No. It can preserve a harder-to-alter history of submissions and editorial actions, but it cannot verify that data, images, identities, or conclusions are truthful.

Use layered screening: contributor and affiliation checks, reviewer-account analysis, duplicate-submission checks, text and image-provenance tools, and coordinated human investigation before publication.
Does a blockchain record prove a paper is genuine?
No. It proves, at most, that authorized participants accepted particular workflow entries. The underlying research and identities require independent evidence.
Is the 2019 blockchain publishing framework already proven in practice?
No. It is a proposed consortium design, and the cited paper reports no real-world trial demonstrating reduced fraud.
