Blockchain in Cricket's Data Ledger: Integrity, Governance and the Umpire's Eye

February 14, 2026, seven in the evening. At my small desk in east London, I opened an old spreadsheet. Its name: 'Review Ledger, 2026–2026'. Row after row of timestamps, umpire signals, third-umpire verdicts, ball-tracking frame numbers. Row thirteen had an empty cell. A disputed LBW review whose master frame never became public. The empty cell means one of two things: the data was lost, or someone removed it.

I started this ledger in 2026, my first year studying journalism in London, when I built a 12,000-word spreadsheet on football's VAR trials. That habit never left me when I moved to cricket. Every review, every clause, every timestamp gets logged. Because I keep seeing the same thing: cricket's controversies are not really arguments about law, they are arguments about data. Who saw the data, who did not, how long the data survived—those answers determine the legitimacy of the decision.

Cricket is now a data economy worth billions. Every ball's speed, every shot's angle, every fielder's position is now machine-readable data. Hawk-Eye, UltraEdge, ball-tracking, Snickometer—these are no longer luxuries but integral parts of international cricket. Since the Decision Review System (DRS) was first used in the Sri Lanka versus India Test in Colombo on July 23, 2026, that dependence on technology has only grown.

But who owns this data? Where is it stored? For how long? Who can verify it? Those answers remain vague. Between the ICC, national boards, broadcasters, and technology providers, a quiet power equation governs control of the data. That gap breeds corruption, controversy, and distrust. Blockchain arrives as an attractive answer—a distributed, immutable ledger where every entry is cryptographically linked and timestamped.

My argument is not a declaration. I begin with an event. In October 2026, when the ICC's Anti-Corruption Unit (ACU) banned Bangladesh's Shakib Al Hasan for two years for failing to report corrupt approaches, my first reaction was a question: who recorded those approaches, and where? In which ledger? At which timestamp? The answer was mobile phones, emails, and spoken words. An international sport's governance, and its proof of integrity rests on personal devices. This is where the idea of blockchain becomes relevant.

Layer One: The Data Integrity of DRS and Ball-Tracking

DRS rests on three technologies—ball-tracking (Hawk-Eye or Virtual Eye), UltraEdge/Snicko, and real-time stump cameras. Each review runs roughly eight camera feeds at once, and the decision window is only a few minutes. In that window data is created, processed, delivered to the umpire, and then—often—lost.

Using the same method I applied to build a precedent database on semi-automated offside at the 2026 Qatar World Cup, I analyse cricket's DRS reviews. By my count, a major ICC event in 2026 averaged roughly two to three reviews per match, and the full ball-tracking frame set of each review is not released. Only 'umpire's call' and the final verdict are published. The rest sits on the provider's servers.

Here is blockchain's first clear application: hashing each review's frame-by-frame data onto a permissioned chain. Then, if anyone later claims the data was altered, any party can verify independently. The power asymmetry between the technology provider and the board—the monopoly over the data—shrinks. I opened the 2026 VAR ledger again, and the same clause was staring back: a lack of integrity means doubt over the decision. In cricket that is sharper, because an LBW verdict can swing a series.

The problem is that DRS data is sensitive. It is valuable to broadcasters, priceless to betting markets, and confidential to boards. A layered blockchain can balance these three demands—a public layer holding only hashes and timestamps, and a permissioned layer holding the full frames. That preserves privacy while delivering verifiability.

Layer Two: The Anti-Corruption Ledger

Cricket's biggest governance crisis is corruption. The 2026 Pakistan spot-fixing scandal, the 2026 IPL spot-fixing case (in which S. Sreesanth, Ankeet Chavan, and Ajit Chandila were arrested), the 2026 Shakib ban—at the centre of each lies one common weakness: the integrity of evidence.

The ACU works almost like an investigative agency. It assembles phone records, bank transactions, witness statements, and media reports into a case. But at every step a human can intervene. An evidence file can vanish, a timeline can shift, a witness can be pressured.

Blockchain can add an immutable ledger of moments to this process. Imagine: every interview recording, every evidence file, every timeline entry hashed onto a chain. Whenever any party—board, player, lawyer, or appeals tribunal—claims something was altered, the chain can be verified to establish the truth.

This is no magic. Blockchain cannot stop false information; it only ensures that an entry was not altered later. After evidence is gathered, during a player's appeal, or in the review of a disputed sanction, that verifiability becomes decisive. Just as a referee's eye looks for the clause of a foul, blockchain looks for the origin of an entry. The difference: a human searches, an algorithm proves.

Layer Three: Contracts, Payments and Smart Contracts

Cricket's economy is contract-driven. The IPL auction, the Big Bash, The Hundred, the Pakistan Super League—every league signs hundreds of contracts, salaries, bonuses, and image-rights deals. Where are they stored? On paper, in PDFs, on board servers.

Smart contracts—code-based agreements that execute automatically—offer a real possibility here. If a player appears in a match, a set amount releases automatically; a performance bonus comes from a verifiable data feed; and every transaction is visible on a public ledger. That raises transparency for players, because complaints of delayed wages—common in domestic leagues in South Africa, Sri Lanka, and the West Indies—surface repeatedly.

But I hold a major caveat here. A smart contract executes terms; it does not interpret them. If a performance bonus is triggered by being 'in the top five', who is number five—that question is not answered in code, but in law. The Russia review log taught me that a tournament is a legal document written in 90-minute chapters, and in cricket too every series is a chapter of statutes. A smart contract keeps the accounts of that document, not its interpretation.

Layer Four: Fan Engagement, NFTs and Fan Tokens

Since 2026, a wave of NFTs and fan tokens has hit cricket. FanCraze, Rario, Socios—these platforms have released digital collectibles and fan tokens for cricketers. Partnerships with the IPL and other leagues have followed, and some boards are hunting new revenue streams from this technology.

Here a key question arises. If fan tokens convert into governance rights—that is, fans voting on club or league decisions—how real is that? Most fan tokens today give only 'opinion polls', not decisions. Built on blockchain though they are, power stays centralised with boards and leagues.

To me this is a marketing layer, not a governance layer. A token gives a fan a vote, but it cannot change a rule of the game. I am not deceived here; I simply note that the language of technology often covers the reality of power. Fans are given the feeling of participation, not a share of decision-making.

Still, the real application of blockchain in ticketing cannot be denied. Counterfeit tickets are an old cricket problem. A blockchain-based ticketing system can track ownership of every ticket, control resale, and verify authenticity at stadium entry. That is a clean, uncontroversial use of the technology.

Layer Five: Broadcast, Domestic Cricket and the Bangladesh Context

Cricket's biggest economic flow is broadcast rights. The IPL's broadcast rights are now a business worth hundreds of billions of rupees, and ICC global event deals are even larger. Every clause, every amendment, every renegotiation of these deals creates a complex paperwork universe.

Blockchain can act as an audit layer here. If every broadcast deal, every amendment, every payment sits on a timestamped ledger, then who said what and who changed what can be verified independently. For boards like the Pakistan Cricket Board, Sri Lanka Cricket, or Cricket West Indies, whose financial management is repeatedly questioned, a public ledger can create pressure for reform.

The issue sharpens in Bangladesh. Within the Bangladesh Cricket Board, elections, contracts, and financial management have long been disputed. Across the Dhaka Premier Division's domestic cricket, the Bangladesh Premier League, and the national team's central contracts, a lack of transparency has repeatedly generated allegations. I grew up between these two cultures—Bangladesh's domestic system, where much is settled verbally, and the UK county system, where every contract and every board minute is documented. Blockchain can be a bridge between these two worlds.

The most realistic application to me is a ledger of domestic cricket wages and contracts. In Bangladesh's domestic leagues, complaints of delayed player wages are not new. With a permissioned chain holding every contract, every instalment, every payment timestamp, a player, a newsroom, or an audit body could verify independently who was paid and who was not. That is not proof of corruption, but it is the first step toward accountability.

The Contrarian Angle: What Blockchain Cannot Do

Against all the promises I have written so far stands a hard truth. Blockchain is a ledger, not a judge. It ensures an entry was not altered, but it does not verify whether that entry is true. 'Garbage in, garbage out'—if wrong data enters at the ground, blockchain immortalises that wrong data.

Go deeper, and cricket's governance is centralised. The ICC, boards, and leagues—their power rests on control of information. Few institutions want to write their own weaknesses into an immutable public ledger. So a large gap exists between blockchain's technological possibility and organisational will.

And most important—the interpretation of law. In an LBW review, whether 'umpire's call' stands depends on a clause of the ICC playing conditions that changes each year. The validity of a catch depends on the on-field umpire's discretion. Blockchain cannot replace that discretion; it can only make the process transparent. A referee's eye and an algorithm do not do the same work—one judges, the other records.

So when I hear of blockchain in cricket, I separate two kinds of claim. The integrity of evidence—that is blockchain's real capability. The neutrality of decisions—that remains in human hands. An analyst who cannot tell these apart mistakes a marketing message for a solution.

Takeaway: Looking Forward

The empty cell in row thirteen of my ledger is still empty. Perhaps it will stay empty forever. But the question remains: if cricket wrote its own decisions into a verifiable ledger, how many controversial calls would today become questions of data rather than disputes over decisions?

The 2026 cricket calendar brings new ICC events, expanded leagues, and more technology. Every new camera, every new sensor will generate more data. The question is whether the framework to protect that data's integrity is growing at the same pace. My suspicion is no. But a timestamped ledger, a hash, a timestamp—change can begin with these small steps. Because in the end, cricket's controversies are not about law, but about proof. And proof belongs not on paper, but on a ledger.
