The Ledger of Decisions: Football's VAR Crisis, Blockchain and the Search for Immutable Proof

On 16 June 2026, at the Kazan Arena. France versus Australia, the group stage. In the 58th minute, Antoine Griezmann releases the ball inside the penalty box and goes down after taking a tackle on his right leg. Referee Andrés Cunha does not blow his whistle immediately. He puts a hand to his ear—waiting for someone on the radio. Three letters light up on the giant stadium screen: VAR. I had sat that day with a stopwatch, because I knew the moment was history. I counted 3 minutes 15 seconds. The first VAR penalty in World Cup history.

For those 3 minutes 15 seconds the stadium was silent. French supporters looked at the referee, Australians were furious. But nobody knew what was being said inside, which frame was being viewed, who was making the decision. The screen simply read 'review in progress'. Nothing more. That day I understood: the problem was not the foul—the problem was the proof. There was no immutable ledger of the decision being made, one that anyone could go back and verify. I went back to the tape, because the tape never lies—only the angle does.

VAR did not arrive overnight. At the 2026 Confederations Cup, FIFA tested it on a large scale for the first time. I sat in Barishal coding every video review from eight matches. Twelve reviews, eight matches. Chile versus Cameroon's overturned goal, Portugal versus Mexico's offside call—the average review time came to 2 minutes 40 seconds. The interesting part: no broadcaster ever explained the protocol. Viewers saw only the outcome, never the process. That is where my question began: if a football decision is a transaction, where is its ledger?

The core idea of blockchain is simple—every transaction is recorded in an immutable ledger, with a timestamp, and once written it cannot be quietly altered. Football's VAR walks the opposite road. The decision is made inside, the evidence sits on private servers, and the outside world receives only a final announcement. The referee's voice, VAR's frame selection, the communication gaps—none of it is documented. In other words, football's decisions have no 'ledger', only a 'declaration'. That distinction is what I want to show today.

Football's real VAR crisis lies not in the rules of the game but in the recording of decisions. When a goal is disallowed, the reason for disallowing it is not verifiable. On the night of Chile versus Cameroon, the Cameroonian supporters simply could not believe why their goal was taken away. Nobody explained the reason; only the outcome was shown. Coding twelve reviews, I saw that two camera angles of the same incident tell two different stories. What looks 'clear' from one angle looks 'doubtful' from another. Yet which angle was used is never documented.

During the 2026 France versus Australia match I tracked the referee's body language as data. Cunha first gestured toward no-penalty, then paused, then put a hand to his ear, then looked at the screen. Each gesture was part of a decision, but none of it was recorded anywhere. What was that three-minute silence? It was a void created by the absence of a process. I found that three minutes of silence can overturn a goal, a crowd, and a nation.

Here is where blockchain becomes relevant. In a blockchain, before a transaction is confirmed, every node verifies it, and the record of that verification is permanent. If every VAR decision in football were written into an immutable ledger—with time, trigger, camera angle, participants in the discussion, and the final reasoning—then even a decision from two years ago could be re-examined by anyone. That transparency is what is missing today. My template had four columns: time, trigger, camera angle, outcome. If these four data points were mandatory for every review, football decisions would no longer be a matter of guesswork.

What I learned from the 2026 Confederations Cup is this: technology does not deliver justice by itself; the documentation of technology delivers justice. A VAR system can run a thousand reviews, but if none of them has a ledger, every review disappears into a black box. I used an economic model back then: the referee as an agent with limited attention and reputational risk. When none of his decisions is documented, his reputational risk cannot be priced—meaning the market of accountability becomes ineffective.

Imagine if a blockchain-style ledger existed. The ledger of that Griezmann penalty decision would read: time 58:14, trigger—tackle in the box, camera—rear angle (ball-foot contact clear), discussion—VAR team and on-field referee, decision—penalty, reason—illegal contact. Such a record could not be erased by anyone, hidden by anyone. Months later any journalist, any supporter, even any referee instructor could go back and see why this decision was made, and what decision was made in a similar situation before. The gap between expectation and reality that unsettles football today is born largely out of this absence of documentation.

But here a counter-intuitive question arises, one I will not avoid. Suppose every decision is permanently documented. What then? The referee would have nowhere to hide—but equally, each of his mistakes would remain an eternal memory. In football history referees have never been this transparent, because technology never demanded transparency before. Now it does. The question is whether this transparency will make the referee more careful, or merely more timid.

Personally, I think fear is not necessarily a bad thing. When a decision has no alibi, the quality of the decision improves on its own. When the stadium empties, the home bias does not disappear—it just loses its alibi. In the same way, when crowd pressure and the question of 'who is watching' are removed from the decision, the referee looks only at the rule and the frame. The philosophy of blockchain matches football here: a system that makes proof permanent also cleans up the act of deciding.

I am a realist, though. I know governing bodies will not run a decentralised ledger, because losing central control is not to their taste. Where VAR decisions are stored, who owns them—the answer today lies with the authorities. So the argument is not technical, it is political. Blockchain arrives here as a philosophy: when power lies in the ownership of the ledger, transparency always becomes a matter of compromise. Football is no exception.

Now to the point nobody wants to admit. We want to see VAR as 'justice', because when a white-and-black frame appears on screen it feels as though truth has been discovered. But between the transparency of evidence and the justice of a decision there is a gap that does not shrink as frames multiply—it grows. Because every new frame opens the door to a new interpretation. So football's real challenge is not adding technology, but adding accountability to technology.

When I took over the editorship of Krira Jagat in 2026, I saw that what people can know about an event depends on who is recording it. In the radio era I was a voice, in the newspaper era an editor. Now, in the data era, I see that if a decision is not recorded it is not memory—it is rumour. Football's VAR crisis is really an information crisis. I realised my job is not to decide; it is to show the decision where it came from.

It is pleasant to imagine if after every big match a public ledger were published—time, trigger, camera, reason. A different culture would emerge: supporters would no longer spread rumours against referees, because verifiable proof would be within reach. No referee could quietly change a decision, because the ledger is immutable. And no authority could dodge responsibility by saying 'the process is secret', because the process itself would be public.

This is not a solution, though; it is a direction. Blockchain will not make football perfect, because in the end the decision is human. But if the proof is human, then the right to verify that proof should also be human. My forty-six years of observation tell me that football's biggest changes come not from technology but from the demand for accountability. VAR has arrived, but accountability is still on its way.

I leave the final question to the reader. If at the next World Cup every VAR decision were recorded in an immutable ledger, and you could verify it yourself—would you trust the referee's decision, or the ledger? The answer would perhaps say that our problem was never the referee; our problem was waiting for a decision in the dark. The day that darkness lifts, the distance between football and VAR will vanish too.
