The most-cited academic works on blockchain date from 2016 onwards and are surveys and application papers. Yli-Huumo et al. (2016) mapped early research, Zheng et al. (2018) surveyed challenges and opportunities, and Casino, Dasaklis and Patsakis (2019) classified applications. The Internet of Things (Christidis and Devetsikiotis, 2016) and supply chains (Saberi et al., 2019) are the most-studied uses. The Bitcoin white paper has no DOI and is not in this list.
How the literature is organised
The academic literature starts with stock-taking. Yli-Huumo et al. (2016) asked where blockchain research stood and found that over 80% of the papers they reviewed focused on Bitcoin, mostly on privacy and security limitations. Zheng et al. (2018) set out architecture, consensus algorithms, challenges and opportunities. Casino, Dasaklis and Patsakis (2019) systematically reviewed and classified blockchain-based applications across sectors. Pilkington (2016) is a handbook chapter on principles and applications.
From there the literature is organised by application. Christidis and Devetsikiotis (2016) explained how blockchains and smart contracts could let devices transact without a trusted intermediary, and Khan and Salah (2018) and Reyna et al. (2018) reviewed security and integration challenges. For supply chains, Saberi et al. (2019) connected blockchain to sustainable supply chain management. For energy, Andoni et al. (2019) reviewed projects and research. Health data management (Yaqoob et al., 2022) and accounting and auditing (Han et al., 2023) have their own reviews.
Main debates
In the management literature the listed papers pull in two directions. Supply chain papers examine blockchain as a way to provide trust, traceability and transparency (Centobelli et al., 2022), while Kouhizadeh, Saberi and Sarkis (2021) explore the barriers to adoption. Operations researchers have modelled when adoption pays off, for example against counterfeits (Pun, Swaminathan and Hou, 2021). In computer science the listed surveys concentrate on technical challenges (Zheng et al., 2018), security (Li et al., 2020; Guo and Yu, 2022) and smart contracts (Khan et al., 2021).
Where recent work is heading
Recent highly cited work covers decentralised finance (Schär, 2021), the circular economy (Upadhyay et al., 2021), textile traceability (Agrawal et al., 2021), big data (Deepa et al., 2022) and the metaverse (Huynh-The et al., 2023; Yang et al., 2022). Yli-Huumo et al. (2016) noted that many proposed solutions lacked concrete evaluation; whether that still holds in your application area is worth checking in the recent reviews.
Most-cited foundational papers
Published before 2021 and ranked by how often later work cites them. Read the abstract of each and the full text of the three or four closest to your question. Citation count measures attention, not quality, so treat this as a map of what the field has argued about rather than a ranking of what is true.

Most-cited papers since 2021
Primary studies and conceptual papers from 2021 onwards. A paper published in 2024 has had a few years to accumulate citations where the works in the section above have had decades, so compare these counts with each other rather than with the ones above.

Recent reviews and meta-analyses
The fastest way into a literature. A good review gives you the structure of the field, a reference list to mine and, in its limitations section, the gaps other researchers have already spotted.

How big the literature is, and where it is published
OpenAlex indexes 112,145 works whose title matches this topic. The chart shows how many were published each year from 2000 to 2025; the current year is left out because it is incomplete.

Search strings to copy
Written for databases that accept Boolean operators (Scopus, Web of Science, ERIC, PubMed, EBSCO). Quotation marks keep a phrase together, an asterisk stands in for the end of a word, and OR groups go in brackets. British and American spellings are written out with OR rather than covered by a single-character wildcard, because those wildcards differ between databases: PubMed’s help page documents the asterisk only, and asks for at least four characters before it. Limit the search to title and abstract first; widen it only if you get too little. Our guide to starting a literature review covers how to record what you searched.
Technology and security
blockchain AND (consensus OR scalability OR security OR privacy OR "smart contract*") AND (survey OR review OR analysis)
Supply chain

Finance
(blockchain OR "distributed ledger" OR "decentralised finance" OR "decentralized finance" OR DeFi) AND (bank* OR payment* OR "financial market*" OR regulation)

How to cite these papers
Every paper above has a DOI, a part of the reference that is easy to leave out. Here is one of them, “Blockchains and Smart Contracts for the Internet of Things” (2016), in the two styles students ask about most:

Check the details against the article itself before you submit: databases, including the one behind this page, sometimes carry the online-first year rather than the volume year. Full rules and more examples are in our guides to APA, MLA, Chicago, Harvard, Vancouver and ABNT, with the rest in the citation guides. You can also format a reference from its DOI with our free citation tools.
Frequently asked questions
How do I cite the Bitcoin white paper?
Satoshi Nakamoto's 2008 paper, Bitcoin: A Peer-to-Peer Electronic Cash System, was self-published online and has no journal or DOI. Cite it as a web document or report in your style, with the URL and the year 2008. Our citation guides cover reports and web sources.
Is blockchain research still active?
Yes. OpenAlex counts more than 18,000 titles for 2025, the highest year so far. The most-cited recent reviews on this page cover combinations with big data (Deepa et al., 2022), AI and the metaverse (Yang et al., 2022; Huynh-The et al., 2023) and sector uses such as health data and accounting.
What are the main criticisms of blockchain in the academic literature?
Start with the papers on this page that are about limitations. Yli-Huumo et al. (2016) found that many proposed solutions to blockchain’s privacy and security limitations lacked concrete evaluation of their effectiveness. Zheng et al. (2018) discuss technical challenges, Li et al. (2020) survey security, Khan et al. (2021) cover challenges for smart contracts, and Kouhizadeh, Saberi and Sarkis (2021) analyse adoption barriers in supply chains.
How this page was made
The lists come from OpenAlex, an open index of scholarly works whose data are published under a CC0 licence, queried on September 21, 2026 for works whose title matches blockchain. Only works with a DOI are listed. Each one was checked against the publisher’s own record at Crossref or DataCite (title, year, first author, journal, volume and pages), and in three cases, where the publisher deposited no byline, against PubMed; anything OpenAlex or Crossref flags as retracted was left out, and an editor took out results that matched the words but not the subject. Citation counts are OpenAlex’s on that date and are usually lower than Google Scholar’s, which counts more kinds of document. Ranking by citations tells you what a field has relied on, not what is correct; several heavily cited papers on any topic are cited because later work disputes them. Books without a DOI are missing, which matters in fields where the founding text is a book.
