Federated learning meets blockchain in decentralized data-sharing: Healthcare use case
Open accessAbstract
In the era of data-driven healthcare, the amalgamation of blockchain and Federated Learning (FL) introduces a paradigm shift towards secure, collaborative, and patient-centric data-sharing. This paper pioneers the exploration of the conceptual framework and technical synergy of FL and blockchain for decentralized data-sharing, aiming to strike a balance between data utility and privacy. FL, a decentralized machine learning paradigm, enables collaborative AI model training across multiple healthcare institutions without sharing raw patient data. Combined with blockchain, a transparent and immutable ledger, it establishes an ecosystem fostering trust, security, and data integrity. The paper elucidates the technical foundations of FL and blockchain, unravelling their roles in reshaping healthcare data-sharing. The paper vividly illustrates the potential impact of this fusion on patient care. The proposed approach preserves patient privacy while granting healthcare providers and researchers access to diversified datasets, ultimately leading to more accurate models and improved diagnoses. The findings underscore the potential acceleration of medical research, improved treatment outcomes, and patient empowerment through data ownership. The synergy of FL and blockchain envisions a healthcare ecosystem that prioritizes individual privacy and propels advancements in medical science.
Overview

Written from the paper’s full text.
TL;DR
The paper proposes a conceptual framework combining federated learning and blockchain for decentralized healthcare data-sharing, using FL to keep raw data local and blockchain for encrypted, immutable transaction records. It illustrates the approach with the Iris dataset and simulated attacks, reporting low attack success rates but no real-world healthcare deployment.
Key findings
- The FL–blockchain synergy is claimed to enhance security, privacy, interoperability, transparency, and resilience for decentralized data-sharing, addressing the trade-off between data utility and patient privacy.
- The framework is demonstrated with the Iris dataset: 150 samples from three Iris species, with four features; FL keeps raw data local, while encrypted attributes (sepal length, sepal width, petal length, petal width) are recorded on the blockchain and the species label remains unencrypted metadata.
- Simulated adversarial Hospital C launched replay, identity masquerade, and man-in-the-middle attacks; defense mechanisms—nonce/hash verification, RSA-based digital signatures with IP verification, and end-to-end encryption—produced low success rates across attack types, with man-in-the-middle slightly higher, as shown in Fig. 8 (no numeric values are given in the text).
- Healthcare opportunities identified include remote patient monitoring, collaborative research and treatment optimization, and regulatory compliance/consent management for HIPAA, GDPR, and similar rules.
Methods
- Conceptual framework and architecture integrating FL and blockchain, with algorithms for data retrieval, data transaction, proof-of-work, authorization checks, and adversarial attack simulation.
- Use case involving hospitals A and B with local datasets; the Iris dataset serves as the primary dataset, FL handles preprocessing/distribution, blockchain stores encrypted attributes, and Hospital C acts as a malicious third party.
- Evaluation is qualitative/empirical: attack success rates are presented in Fig. 8, and complexity analysis is given for encryption, retrieval \(O(n*d)\), proof-of-work \(O(2^k)\), and authorization \(O(n)\) or \(O(\log n)/O(1)\).
Limitations
- The paper states challenges including interoperability, scalability, consensus, security, privacy, and data quality; the conclusion also states that “a specific real-world healthcare use case is not presented.”
- Evident from the text: the evaluation uses the Iris dataset rather than real healthcare data, and no FL model accuracy, clinical outcomes, or deployment results are reported.
- Evident from the text: attack success rates are described only qualitatively from Fig. 8 without numeric values, and scalability, energy consumption, and regulatory compliance are discussed as challenges rather than empirically tested.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
