No Certainty Without Verification: Football's Lesson from VAR, Blockchain and the Discipline of Insufficient Information

December 9, 2026, Lusail Iconic Stadium. Argentina versus the Netherlands, a quarter-final, and the match has spilled deep into extra time. I was in the press tribune in Doha, live-tweeting, but my attention was not on the scoreboard. It was on referee Mateu Lahoz's pocket, and on his hand. In that single match, Lahoz showed a record eighteen yellow cards. Fifteen players, the coach, and a few from the bench. After the final whistle, social media erupted with a single question: had Lahoz lost control? But sitting in the tribune, I noticed something else—everyone wanted a final verdict, yet no one possessed the full information. No one had seen which angle Lahoz had seen, no one had heard the echo of his whistle, no one knew the exact moment the match had nearly slipped from his grip. Still, everyone delivered a verdict. That day I felt that football's real crisis was not the number of cards—the crisis is the habit of demanding certainty without information.

This is not a new disease. In May 2026, at Wembley for the FA Cup final between Arsenal and Chelsea, I sat in the stadium live-tweeting minute-by-minute referee decisions. Referee Anthony Taylor made nine notable calls that day, including a contentious Alexis Sánchez goal. I posted law citations from my seat, using the hashtag #RefereesEye. By full time I had ten thousand new followers. But that very night I learned a hard lesson—live speed and replay speed are not the same thing. What I saw from the stands, what the television cameras saw, and what the referee saw are three different truths.

This is the heart of my story. I am a football law commentator who believes verification comes before the verdict. At the 2026 World Cup in Russia, during France versus Argentina in Kazan, I called "no penalty" on air, then corrected myself forty seconds later to call the VAR penalty. Out of that embarrassment I built a habit that forms the foundation of this piece: when there is no information, say "I don't know." This article is about exactly that habit—why football, and football's newest technology, blockchain, keep falling into the trap of false certainty in the face of insufficient information.

Context: Football's Long Struggle to Verify

Technology entered football step by step, and at every step the same question returned—is the machine helping the human, or taking away the human's authority? In 2026, at the Brazil World Cup, goal-line technology arrived, proving for the first time with clarity whether the ball had crossed the line—something the naked eye could never state with certainty. In 2026, in Russia, came the Video Assistant Referee, or VAR. Then at the 2026 Qatar World Cup came semi-automated offside technology, where twelve cameras and a sensor inside the ball draw the offside line with centimetre precision. At every stage the game became more measured, and at every stage the question grew louder: is this measurement the truth, or merely another layer of truth?

That question has now returned on football's other front, in the form of blockchain. Several English Premier League clubs, major European brands, and even La Liga are leaning toward fan tokens, non-fungible token ticketing, and club-crypto partnerships. Through the Socios platform, supporters buy tokens and gain the right to vote on club decisions—which song plays, which design is chosen, which charity receives funds. The technology is elegant. But its underlying philosophy aligns remarkably with football law: a ledger that cannot be altered, that everyone verifies together, that lets no one cheat.

VAR and blockchain are really two members of the same family. Both were born from a crisis of trust. People did not trust the referee, so the replay arrived. People did not trust the banks and the club authorities, so the decentralised ledger arrived. Both want the decision to be open in front of everyone, the evidence visible to all. But this is where the story becomes complicated, because football people never want only evidence. They want a verdict, emotion, heroes and villains.

Core Analysis: How Verification Works, and Where It Breaks Down

The biggest lesson of my journalism career came from an empty data field. When every box of an analysis reads "insufficient information," there are two paths. One, fill the boxes with imagination—invent a team, invent a star, invent a narrative. Two, honestly say: I don't know. The first path is easy, popular, and dangerous. The second is hard, dull, and the only path that leads toward truth. In football I have chosen the second, and in this piece I want to prove exactly that—verification is not a technology, it is a moral position.

Let us first look at the technical architecture of verification. In blockchain, each transaction enters a block, each block carries the hash of the previous block, and thousands of nodes across the network independently verify each block. If anyone wants to change a number, they must change the entire chain—practically impossible. That is its strength: the past cannot be altered, because the past is written in everyone's hands. Now consider VAR. Before awarding a penalty, the video assistant referee looks at multiple camera angles, moves through multiple frames, tests multiple speeds—normal, slow, super slow. If the evidence is not "clear and obvious," he upholds the on-field decision. Notice, both systems share the same principle: until the evidence is certain, the decision is not changed.

But football does not follow this principle, because football's main actors never sit down with logic. I remember my spreadsheet—after the 2026 World Cup I re-watched all sixty-four matches and logged twelve VAR interventions. For each intervention I kept two data points: what the on-field referee first said, and what happened after the replay. The result was astonishing—in many cases the on-field decision was correct, just for a different reason. In many other cases the on-field decision was wrong, but no one could catch it, because the camera angle was incomplete. No one worried about this incompleteness. Everyone only wanted the verdict.

This is where I find football's deepest crisis: we verify the outcome, not the process. We ask whether a VAR decision was right or wrong. But we never ask—how many cameras were there, how many frames, how many centimetres of grass beneath the ball, and what was shown to the referee on the screen. Yet the whole beauty of blockchain lies exactly here—it keeps not just the outcome but the process open. Every transaction's timestamp, every node's verification, everything is exposed for all to see. Football's VAR unfortunately has not taken this path. Its rules, its protocol, its audio—all are hidden from the viewer. The technology arrived, but transparency did not.

Here is my first deep observation, which I understood after years of sitting in stadiums: verification technology and a verification culture are not the same thing. A club can spend millions to launch a fan token, but if it does not give token holders real power, that is just branding. Equally, a league can spend tens of millions to install semi-automated offside, but if it does not open the referee's conversation and protocol to the public, it is merely creating a new controversy, not solving the old one. At Qatar 2026, sitting in the tribune, I noticed spectators screaming at the offside line, yet no one knew which frame the line had been drawn in. In the same match, the difference between two frames can be a few inches, enough to flip an entire result. But the decision came, and with it came finality. Even with a deficit of information, the language of certainty does not change.

My Experience: Stadium Noise, the Microphone and the Empty Stadium

When football paused in 2026 and the Bundesliga returned, I commentated Dortmund versus Schalke from a London studio—the score was 4-0, the referee Deniz Aytekin. The stadium was empty. But precisely in that emptiness I heard things I had never heard before. The echo of Aytekin's whistle, his shouts, his conversations with players—all clear. In that empty stadium, the microphone became the twelfth man. I wrote an eight-part thread on referee communication.

That experience opened another layer of verification for me. Until then I verified video—what the camera saw. Now I understood that the microphone is also a witness. What the referee said, when he said it, in what tone—football never records this information. Yet the core lesson of blockchain is to record every piece of data, preserve every message. If football truly wants transparency, it must preserve the referee's audio too—not just camera frames. Italy's Serie A and England's Premier League have begun releasing VAR audio in recent years, a small step in the right direction. But it is still incomplete, because only a few selected incidents are released while the rest stay hidden. Selective transparency is not transparency.

Here I want to admit a truth that is uncomfortable for a referee-minded writer like me to state. Replay has made us certain, but it has not made us wise. When a decision changes after replay, we only know that it changed. We do not know why the first decision was wrong, what the referee saw to err, or what the video assistant saw to catch it. Without knowing the cause, we cannot learn from the system. And without learning, the same error will recur in the next match. This is the true meaning of verification—not just correcting one incident, but keeping the entire process open.

Blockchain's Lesson: What Football Can Learn

I am not a technology romantic. I know there is plenty of fraud in the blockchain world too—thousands of tokens with no underlying value, thousands of projects that are merely machines for extracting money from supporters. After 2026, when the fan token market ballooned, many clubs' values came under question. The principle of doing business with supporters' emotions is not new, but in the digital age emotion converts into money more easily. So I do not blindly praise blockchain. I speak only of one central principle: every claim must have evidence behind it, and no one person can hide the evidence alone.

This principle is badly needed in the football transfer market. My second deep opinion is this—transfer market data models overvalue youth potential and undervalue dressing-room chemistry. A club spends tens of millions on a nineteen-year-old prospect because the model says his market value will rise. But the model never measures whether the boy will fit into the dressing room, whether he will clash with the senior star, whether he will collapse under pressure. Here lies a limit of information that no algorithm can ever fill. And this is the limit of my verification philosophy. I do not say everything can be measured. I say that what cannot be measured should be stated clearly.

My first deep opinion is also relevant here. The five-substitute rule benefits deep squads, but it also lets big clubs turn the final twenty minutes into a war of attrition. In the closing phase, when the deep-squad club sends on five fresh players and the smaller club tires, what happens on the scoreboard is not really the match's momentum—it is the gap in resources. That gap can be measured, but it cannot be explained by numbers alone. Here too the same lesson: information matters, but information alone is not truth.

Contrarian Angle: Emotion versus Law

Now I come to the part that pains me most in my profession. Football law can be clear, evidence can be clear, but the spectator's emotion is never clear—and it is this emotion that actually drives the game. In that 2026 Argentina-Netherlands match, two entirely opposite interpretations of Lahoz's eighteen cards emerged. One camp said he had lost control, that so many cards would not have come with a cooler head. Another said the exact opposite—he held the match together, because fewer cards in that environment would have turned the game into a brawl.

Notice that both sides had the same information—eighteen cards. Yet the interpretation was entirely different. In other words, even with information, certainty does not arrive unless we understand the context of the information. How many cards Lahoz showed is information. But which card was a tough match-management decision and which was an emotional reaction is context. Without knowing this context we deliver verdicts, and those verdicts become another controversy, another social media storm.

This is why I believe the greatest journalistic duty in modern football is to admit that we do not always know. Blockchain taught me this lesson in mathematical form—if there is no data, no decision is made. Football taught me this lesson in emotional form—if you are not certain, do not shout. Both are really the same statement.

Yet I admit that this position of saying "I don't know" is not popular. The spectator wants a verdict, because without one he is uncomfortable. Football is a game of narrative, and narrative needs heroes and villains. The referee often becomes the villain, because he is the only person who, in the name of law, stops emotion. This is the referee's true tragedy. If he does not apply the law, the game descends into chaos. And if he does apply the law, he becomes cruel in the spectator's eyes. Blockchain's nodes sit in exactly this position—if they follow the rules, transactions halt; and if they do not, the system itself becomes meaningless.

Takeaway: Time to Build a Verification Culture

I know that in this piece I have not made a grand prediction about any team or any star. Because I do not have the information to make that prediction. This is my position. Football's next decade will be spent building a verification culture—not merely installing technology. If clubs and leagues can apply blockchain's transparency principle to football law, if they can open the context, audio and angles of every major decision to the public, then perhaps a day will come when the referee no longer has to be the villain. He will then be part of the system, written in everyone's hands, unalterable by any one person.

The question now is not whether technology will come—it is already here. The question is whether we will abandon the old habit of certainty without information. When the next controversial decision arrives and someone shouts "it's obvious," my one request will remain: show the evidence first. Show where the camera was, which frame, what the referee said, and which protocol was followed. If that evidence is absent, say the bravest thing: I don't know. Because a system that can admit its own ignorance is the only system that can give people the truth. Football and blockchain, two worlds, one lesson—no certainty without verification, and no true game without certainty.
