Blockchain in Cricket Data Trust: Technology or Promise?

Last December, a franchise T20 match's bowling figures were shown three different ways across three platforms. One bowler conceded 29 runs in 4 overs on one platform, 31 on another, and 30 on the third. The difference is small — but when betting markets, fantasy apps and player valuations are built on these numbers, a single run discrepancy is no longer small. The first number I checked was not the fee; it was the timestamp. The 14th over of the match — when it started and when it ended — showed a gap of 6 minutes 42 seconds. No rain, no injury, no DRS. So what caused this long delay? No one could answer — because there is simply no audit trail anywhere.

This question is not about one match — it spans the entire cricket data ecosystem. In modern cricket, each ball generates an average of 40 to 60 data points: speed, swing, bounce, timestamp, field position, run rate. This data is used everywhere — from scorecards to TV graphics, betting odds to player auctions. But who verifies this data? The question is simple; the answer is far more complex. The global cricket technology market reached approximately $3.2 billion in 2026, projected to double by 2030. A large portion of this market covers data analytics and fan engagement technology. But data integrity — the verification of information authenticity — remains the most neglected sector.

The situation in Bangladesh is even more complex. Domestic cricket still enters data from handwritten score sheets. Cameras exist at grounds, but there is no technology-based verification for every ball. Recently, after a run-out controversy in a Bangladesh Premier League match, it emerged that the third umpire did not have complete ball-tracking replay data. This is not corruption — it is the everyday reality of a system without audit.

Blockchain technology has arrived with promises to fill this void. In the past year, at least four cricket-adjacent organisations have announced the use of distributed ledger technology for data verification. One platform proposed creating hashes of ball-by-ball data stored on an immutable ledger. Another said it would record match results in smart contracts instead of scorecards. The pitch is impressive — but the question is, does this technology solve cricket's real data problems, or is it just a symbol of a solution?

From my post-furlough database of 4,000 matches, I selected eleven matches where raw event data and published data showed inconsistencies. Of these eleven, four had data entry errors (wrong bowler, wrong runs), five had timing gaps, and two had unclear decisions. None of these proved deliberate manipulation — but none could be verified either, because there is no independent audit trail.

Here, blockchain's argument stands: if each ball's data is stored on a decentralised ledger, no single party can alter it. The concept is logical. Since the controversy over ball-tracking data used in the 2026 ICC World Cup final, the transparency of match records has been a major question. An immutable record system could resolve part of that debate.

But in the 2026-24 season, I collected raw event data from 23 matches in Bangladesh's domestic T20 competition and found three layers of problems. First, timing mismatches — 9 matches showed abnormally long gaps between the end of one over and the start of the next. Second, bowling order anomalies — bowling changes that did not fit the match situation. Third, data aggregator differences — different statistics for the same match across different platforms. When stars like Mustafizur Rahman or Shakib Al Hasan have their performance records displayed differently across three platforms in the Bangladesh Premier League, it affects everything from subsequent auction bids to national team selection. One specific example: in a 2026 BPL match, an objection was raised over the delivery count in the 17th over. TV graphics showed 6 balls, but the scorecard showed 7 balls in that over. This one-ball difference — deliberate or not — could change a match result if a wicket or runs in that over proved decisive.

Now, the critical observation: none of these three problems will be fixed by blockchain. The timing mismatch will remain a mismatch on the ledger, because the problem is not record-keeping — it is the moment of record creation. The bowling order anomaly will become immutable in a hash function, but if it was wrong from the start, it will stand as a permanent error. And the data aggregator difference — that is a flaw in human-built software; on a ledger, it will simply receive a permanent version.

On the other hand, blockchain can bring genuine change in cricket where it matters — transparency in player contracts and transfer transactions. Speaking from my experience as a transfer market administrator, loan-with-obligation deals are destroying the financial planning of smaller clubs. If smart contracts recorded the terms, payment schedules and bonus structures of these deals, smaller clubs would have far stronger defences. It is in these transactions that ledger technology can be most effective.

But here lies the danger. When we hear blockchain's promises, a misconception forms — that technology itself is transparency. In reality, an incorrect data point becoming immutable means immortalising that error. I speak from my audit of 412 transfer rumours — the reliability of information is determined by the incentive of the source, not the record system. If a dishonest scorer sends a wrong entry to the ledger, the ledger will establish that error as "truth" — closing the path to correction.

During eleven weeks of furlough building a 4,000-match database, I saw how people make data entry errors. Fatigue, haste, inattention — these ordinary causes produce errors. Technology does not solve these errors; sometimes it makes them harder to fix.

Meanwhile, when organisations adopt blockchain solutions, a demonstration effect emerges — "we are using modern technology" — but there is rarely sufficient independent scrutiny to verify whether genuine auditing is actually happening. When I tried to verify one match-data platform's ledger verification claim, I received no answers — they would not even provide a list of what data points were stored on the ledger. That is troubling.

In corruption prevention, technology is a tool, not a solution. The question that ICC's Anti-Corruption Unit and various boards should be asking is not about technology, but about training and mindsets. When domestic cricket scorers understand that every entry they make can later be verified; when journalists have the opportunity to question every layer of data; that is when real change will come from human accountability — not from a technology ledger.

Next season, what I will be looking for is — who takes responsibility for the data? When a company claims blockchain-verified data, my first question will be: what is the correction process if an incorrect entry is found? My second question: who audits that ledger? If the answers to these two questions are clear, then that technology will bring real transparency. The archive does not forget what the timeline tries to hide — and that timeline's account will always remain open in my audit notebook.
