From VAR to Blockchain: Where Football's Decision Audit Trails Go Missing

It was nearly half past nine at night on 16 June 2026, under the floodlights of the Kazan Arena. France versus Australia, the opening round of group fixtures. In the 54th minute, inside the penalty area, Australia's defender Josh Risdon and France's Antoine Griezmann wrestled over the ball. Referee Andrés Cunha did not give a penalty at first. Then he waited on his earpiece. For the first time in World Cup history, a penalty-area decision was referred to the video referee. The decision took more than four minutes. In the end, a penalty. In the 58th minute, Griezmann put the ball in the net. I watched that evening from a digital desk in London, going frame by frame. In June 2026, at the Confederations Cup in Russia, I had logged the first global trial of the video assistant referee system — seventeen interventions across sixteen matches, cross-checked against the numbered articles of the Laws. So the four minutes in Kazan were not new to me; what was new was that it was happening on the world stage for the first time. That very night a question began to settle in my notebook, one that remains just as relevant nearly a decade later. Football takes decisions, explains them, argues over them — but where does a permanent, unalterable, publicly verifiable record of those decisions actually live? In this piece I want to connect two things — football's refereeing protocol and blockchain. It may sound odd. But both revolve around one question: data integrity and the audit trail of process. I write this as a rules analyst who has spent twenty-three years reading football decisions, referee reports and law texts side by side, and who knows that football's biggest weakness is often not in the decision itself but in where the decision gets recorded. THE GAP BETWEEN LAW TEXT AND APPLICATION The International Football Association Board formally introduced the video assistant referee system into the 2026-18 edition of the Laws of the Game. The draft section marked four categories of decision as reviewable: goal or no goal, penalty or no penalty, direct red card, and mistaken identity. Outside these, the referee stands by his own decision. This list is one of the most important passages in the Laws, because it fixes what technology may enter and what it may not. Two threshold phrases attach to it — 'clear and obvious error' and 'serious missed incident'. What the referee saw on the field is the primary decision. The video room overturns that decision only when the error is clear and obvious and materially affects the outcome or the sanction. In the language of the Laws, this is the minimum level of interference. In other words, the job of technology is not to make the decision, but to expose the gap in the process. Here the first problem hides. The Law is clean in writing, but in application it branches into a decision tree. When I cross-checked each of the seventeen interventions at the 2026 Confederations Cup against the articles, I saw that similar incidents produced different outcomes in different matches. On 18 June, in the Chile versus Cameroon match, a Chilean goal was disallowed after review because the ball had gone out in the build-up. That decision was procedurally correct, yet to the viewer it was only 'goal disallowed' — no explanation, no timeline, no article cited. THE DECISION TREE: REVIEWABLE, OR NOT My method always follows a fixed sequence: isolate the incident, check whether it falls within a reviewable category, log the referee's on-field decision, test the threshold, then the outcome. I had built this sequence before the 2026 World Cup, precisely for the reason that it took four minutes to announce a penalty decision in Kazan. Let me break the Kazan incident down step by step. Step one: Risdon's foot makes contact with Griezmann's leg — an incident. Step two: it occurs in the penalty area and falls within the 'penalty or no penalty' category, therefore reviewable. Step three: on the field, Cunha first gave 'nothing'. Step four: the video room checks and finds the contact clear and the foul a penalty — a clear and obvious error. Step five: the decision is overturned, a penalty is given. On paper these five steps are clean. But on the field they take more than four minutes. The first World Cup VAR penalty was not an ordinary call; it was a multi-layered audit, every step of which depended on communication between the field and the room. I went back again and again to the frame where the rule stopped being obvious — precisely at that moment when Cunha waited and the stadium fell silent. That silence is the biggest truth of football decision-making: the viewer knows something is being checked, but not what, under which article, or by whom. My objection is not to the outcome but to the time. A two-minute wait is enough to cool a goal celebration. But four, five, six minutes of drift shreds the rhythm of a match. Players go cold; the crowd sits waiting for a decision that often arrives without explanation. THE GAPS IN THE AUDIT TRAIL This is where my central argument arrives. Football announces a decision after an intervention, but it does not permanently preserve the process behind that decision. The referee's report, the video room's communication, the timestamp of each frame — these are scattered across separate places, often in private or institutional files that the ordinary person never sees. Consider: after a referee's decision we learn that 'a penalty was given'. But we do not know at which frame the decision was taken, which camera angle was used, how many seconds it was watched, or which article was invoked. Nor how strong the contact was, where the ball was at the time, or whether the player was facing the ball. These facts are part of the decision's existence, but not part of its announcement. In 2026, I audited 92 matches played behind closed doors in the German Bundesliga, under contract to a London-based sports-law academy. There I tracked referee communication, advantage calls and disciplinary incidents in cavernous, empty stadiums. I found no stable evidence of a home-advantage shift, but I did note one thing — audible on-field dissent had risen by twelve percent. The number alone says little, but it shows that recording data surfaces new patterns that the naked eye misses. This is where blockchain enters. A blockchain is essentially a distributed ledger in which each entry is mathematically linked to the previous one, and once written it cannot be quietly altered. This technology has already begun to enter football — ticketing, fan tokens, broadcast rights, club ownership. But its real potential lies in decisions, if an unalterable log can be created for every refereeing decision. What could a VAR intervention log contain? The precise timestamp of the incident, the reviewable category, the referee's primary on-field decision, the duration of the video room's check, the article applied, and the final outcome. Once this entry is logged, no one can later claim 'we actually watched for three minutes', or 'we actually didn't apply Article 12'. That is data integrity. SEMI-AUTOMATED OFFSIDE AND THE LIMITS OF DATA The 2026 Qatar World Cup used semi-automated offside technology for the first time. A sensor at 500 Hz was placed inside the ball, and twelve special stadium cameras tracked twenty-nine points of each player fifty times per second. Offside decisions therefore arrived within seconds and were far more accurate in timing. But note, the technology said whether an offside had occurred, not whether it should be given. That remains a human decision. This distinction matters. Blockchain or any sensor technology can give data integrity, can give an audit trail of process, but cannot give the fairness of a decision. A wrong threshold, an inconsistent explanation — technology cannot fix these, only make them permanently visible. Here I want to be cautious. If we assume technology equals fairness, we will be wrong. A blockchain will record that a decision was made, who made it and when — but whether the decision was correct is a question of legal interpretation, not of technology. I always separate process from outcome; the same decision can be procedurally accurate and substantively disputed. In the sports data market there is another problem. Every pass, shot and movement of a match is now sold and fed into analysis. A large part of this data is expected-goals based. My objection is not to xG's existence but to its abuse. xG cannot explain in-game decisions, a player's form, or a referee's standard. Yet many analyses use it as a universal truth. Precisely for this reason, recording data and interpreting data are two separate tasks, and blockchain helps only with the first. TWO PATHS: THE UNITED KINGDOM VERSUS BANGLADESH I was born in Bangladesh and now work in the United Kingdom. I have had the chance to see both countries' referee systems up close, and I stay cautious so the comparison does not become false equivalence. In the UK there is a tiered path of referee development — from local leagues to national leagues, a professional referees' association, regular VAR training and institutional review after every decision. In Bangladesh, referee development runs within far tighter resources, and a centralised, public structure of post-decision review has not yet been built. This difference is not only financial but institutional. If one country builds a permanent audit trail after decisions and another does not, comparing the quality of their decisions becomes difficult. This is why I argue that technology like blockchain could be a big opportunity for smaller leagues — because it can create a publicly verifiable log at relatively low cost, helping to place decisions in big and small leagues on the same standard. In the transfer market I see a pattern repeated again and again — loan-with-obligation deals, where a small club develops a big club's half-finished player and cannot keep its own financial planning in its own hands. The biggest problem in this trend is also one of information — contract terms, future payments, sell-on shares are often opaque, and a neutral, verifiable ledger would at least let smaller clubs be certain of their own rights. Here too the core question is data integrity. EMOTION VERSUS RULE: THE CONTRARIAN ANGLE Now I want to think from the opposite side. Suppose from tomorrow every refereeing decision in football were written to a blockchain — time, article, decision, everything. What would change? First, it would not change the correctness of the decision. A wrong threshold written to a blockchain would look more wrong, because no one could hide behind 'we actually saw it differently'. Second, it would not change emotion. Fans reject refereeing decisions because they do not understand the reasoning, or because the decision goes against their team. Data integrity does not slow emotion; it often brings it forward in a clearer, more reasoned form. There is another danger — with a verifiable log, people begin to assume the decision was fair. That is a dangerous confusion. Whether a decision is fair is a question of legal interpretation and consistency of application, not of how unalterable the ledger is. I do not want to fall into the trap of verifying every procedural step and then accepting every decision as legitimate. Process audit and outcome fairness are two separate questions with two separate answers. FINAL THOUGHT Football has learned to adopt technology slowly, with suspicion, and often in the wrong place. Goal-line technology came first, then VAR, then semi-automated offside. At each step, technology changed the pace of decisions but did not open the reasoning to the ordinary viewer. Blockchain is nothing new here — it is only a tool that can make information permanent and verifiable. The real question is therefore not one of technology but of institution. How fast a decision arrives, how clearly it is explained, and how long that explanation is preserved — the power to settle these lies with football, not with any particular tool. The first World Cup VAR penalty may have been a milestone; but a greater milestone will be the day when every frame behind a decision is laid open for all to see, and no one sits waiting without an explanation. You may think this is imagination. But eight years ago, watching a penalty-area tug-of-war on video was imagination too. Football moves slowly, but it moves.
