When the Replay Goes Silent: Cricket's Decision Review, Data Integrity, and the Real Limits of Blockchain

For decades I have followed one rule. Before I open my mouth on a disputed decision, I look at it from at least three angles — the camera behind, the camera in front, and the ball-tracking. The truth those three layers produce is what I write. But a few days ago, something stopped me. After running an analytical process, what came back was an entirely blank result. No data, no quotations, no sources. Only emptiness. And out of that emptiness came the most uncomfortable question of all — if the replay itself is blank, then which truth are we talking about?

Cricket is heading toward exactly the same crisis, though very few people admit it. Today the legitimacy of a decision on the field rests on data — DRS, UltraEdge, ball-tracking, semi-automated offside. But if that data is lost, corrupted, or deliberately altered, then whose hands hold the fate of the match?

We need the background. In modern cricket, the decision system works on three layers. The on-field umpire rules in an instant. Technology stands beside him — UltraEdge catches the sound, Hawk-Eye draws the ball's path, ball-tracking predicts the future trajectory. And the third umpire sits before a screen, blending all of it into a final call.

The problem is that the balance of power among these three layers is never equal. The on-field umpire's call often becomes technology's final verdict, because the review process builds in a buffer — umpire's call. That buffer creates the most debate of all. But over the past decade, the centre of the argument has shifted. The question used to be, did the umpire get it wrong. Now the question is, did the technology work correctly. And beyond that, is the data we are shown actually real.

After 2026 this shift became obvious. Remote studios, second-screen commentary, and clip-based replay arguments changed the very way cricket law is understood. The box room is now a new courtroom. But a courtroom has one condition — the evidence must be reliable. This is our biggest weakness.

I have broken this crisis into eight layers, exactly the way a match referee structures a report.

The weight of a decision changes with the format. In a Test, the impact of one LBW spreads across five days, while in a T20 that same call can end the match in two overs. In an ODI, the tactic of saving a DRS review for the middle overs is now part of the game. Fail to understand the format and it is easy to reach the wrong conclusion about a decision's fairness.

Player technique and data are the next layer. A batter's average, strike rate, and performance in specific situations must be read alongside technology's verdict. But there is a trap here. Big conclusions cannot be drawn from small samples. Home-ground statistics often mask overseas weaknesses. An age curve has a turning point after which performance suddenly drops, and that is hard to catch in advance.

The team and ranking layer is tied to this. ICC rankings, home and away performance, batting depth, bowling combination, bench strength, age structure — all of it builds the expectation around a match. And that expectation directly shapes decision controversies. When someone loses, the fan searches for a cause, and the easiest cause is the umpire.

The league and commercial layer is now cricket's bloodstream. IPL, BPL, Big Bash — the broadcast rights, franchise valuations, and player salaries of these leagues have all become data-driven. The market model overprices young talent and underprices dressing-room chemistry. That is a large gap, because matches are actually won through chemistry, not spreadsheets.

The law and governance layer is the most sensitive. Power and revenue distribution, playing-rule controversies, anti-corruption, eligibility and selection, geopolitics — without reliable information, no decision in any of these holds up. One disputed selection or one vague rule can destroy an entire tournament's credibility.

At the risk layer we see six kinds of risk — sporting, personnel, commercial, rules-related, public opinion, and systemic. Each has a likelihood, an impact, and a mitigation. The most neglected risk is systemic — if the system collapses, nobody notices until the result of a match changes.

At the public-opinion and expectation layer, the wider the gap between the market's story and the objective assessment, the fiercer the controversy. And at the industry-transmission layer, broadcasting, the South Asian heartland market, the talent supply chain, capital networks, betting and fantasy are all tied by one thread.

Every one of these eight layers rests on a single thing — reliable information. If the information is absent, analysis is impossible, and without analysis a decision has no value. This is where blockchain enters, but without the hype.

Blockchain is not magic. It is a simple idea — once information is written, it is hard to change, and an immutable record remains of who wrote what, and when. Its application in cricket is still early, but the potential is real.

Imagine the full sequence of a DRS decision — which frame showed the ball where, what trajectory ball-tracking displayed, when the third umpire pressed the button — all of it in a sealed, verifiable record. Then claiming after the match that “the technology was wrong” becomes difficult. This is not about protecting the umpire; it is about protecting the truth.

Cricket's most realistic use of blockchain is appearing in ticketing and fan tokens. Supporters are connecting to leagues and clubs through digital assets. Player highlights, memorabilia, collectible digital items — blockchain can solve the problem of verifying ownership and authenticity.

Another area that gets little discussion is the betting and fantasy market. Cricket is now one of the world's largest betting markets. Suspicious betting flows and the subtle signals of match-fixing now require central oversight. If a transparent, verifiable ledger keeps an immutable record of betting flows, it could be a real tool against corruption. But the caution is the same — having a record does not mean transparency, unless someone can read and understand that record.

Here is my biggest warning. Just as technology does not make the replay the final witness to truth, blockchain does not automatically make information true. Blockchain only guarantees the record was not altered. But if the record was wrong from the start, it stays wrong forever — only this time it is immutable.

There is one more layer that is often overlooked — sound. The stump mic can now pick up players' words, and in a silent stadium that sound becomes clearer. In 2026, when much cricket was played behind closed doors, this audio evidence took on a new dimension. Since then I begin every report this way — what I heard, then what I saw. Because the tension on the field, the umpire's hesitation, the player's frustration — these are caught in sound, in a way no frame can catch.

Now to the mistake that harms us most. We easily assume more technology means more truth. Reality is nearly the opposite. More technology means more layers, and every layer means a new chance for error.

Take semi-automated offside. The system uses many cameras and a sensor inside the ball to produce a number. Sometimes that number is so small it sounds final. But the number is actually born inside a tolerance. The camera's frame rate, the calibration, the instant the ball was released — each step carries a small uncertainty. If the frame rate is low, what happened between two frames no one ever sees. Information the camera cannot see is absent from the replay, and treating absent information as truth is the biggest mistake of all.

So my rule is simple. I will not write a number unless it comes from a named system and a stated tolerance. I will not write offside without a millimetre figure, and I will not write a millimetre figure without a document.

In the same way, our understanding of umpire's call is muddled. We often confuse three separate questions. Was the process correct? Was the protocol followed properly? And was the decision actually right? The answers to these three can differ. A decision can be procedurally perfect yet wrong in outcome. And an outcome can be right yet the process flawed. Process, protocol, and correctness — unless these three are separated, every controversy halts at half a truth.

This confusion is why cricket arguments run so long. We ask questions with emotion, but we demand answers in the language of law. Unless we can translate between those two languages, the truth never emerges. In modern cricket, captains like Kohli or Williamson are as aware of how to use a review as they are; what is needed more is awareness of the limits of the review.

And one more thing I have seen again and again. That shift of 2026, when the path from player to umpire, umpire to referee, referee to broadcast voice was created — that was when explaining a decision became a separate profession. Without that transformation, today's box room culture would not exist. But that path has a dark side too. Remote analysis feels cleaner than the reality on the field, and that cleanliness sometimes gives false certainty. The sweat on the field, the umpire's hesitation, the player's anger — all of it stays outside the camera.

My work has a rule — after the result, a verdict must come quickly, because the viewer wants a clear ruling, not a long analysis. That pressure taught me to cut every extra word. But speed and accuracy are not the same. A fast wrong verdict does far more damage than a slow accurate one, because a wrong verdict plants a seed of doubt in the fan's mind.

So what is the path ahead? In my view, cricket's next big question is not about technology, it is about data integrity. Whichever league, whichever broadcaster, whichever umpires' body understands first that a decision's legitimacy rests on the reliability of the data will be the first to win back the fan's trust.

Blockchain can be a tool here, not a religion. It makes information immutable, but it does not make information true. Truth only arrives when we learn to ask — who recorded it, how was it verified, and what can the camera not see.

I am still watching this match from three angles. But now a fourth question has been added. If the replay itself is blank, then which truth are we talking about — and who bears the responsibility for passing off that blank replay as truth?
