Empty Feed, Immutable Ledger: Who Preserves Football's Truth in the VAR Era

Empty Feed, Immutable Ledger: Who Preserves Football's Truth in the VAR Era

June 16, 2026. Kazan Arena. France against Australia, a group-stage match. In the 58th minute, referee Andrés Cunha waited by the headset, then looked at the monitor and raised his left arm for a penalty. Antoine Griezmann converted, and France won 2-1. It was the first World Cup VAR penalty. I was in Dhaka at the time, working remotely as a VAR analyst for a South Asian broadcaster. Across 64 matches I logged 29 VAR interventions, each with its minute, its camera angle, and the exact article of the Laws of the Game it rested on.

I am not sitting down to talk about that replay. I am sitting down to talk about what happened around that night, when the screen in front of me carried no picture at all. There was no title, no source, no data point — only one cell that had been filled in: the domain label, "football." Everything else was blank. The frightening part is that a tidy, confident, well-formatted analytical panel could easily have been built on top of that emptiness. Nobody would have noticed.

That afternoon taught me something about football. We spend enormous energy arguing about referees' mistakes. We almost never argue about the blank cells in the data — yet in the modern game, a large share of decisions is born from exactly those blank cells.

Context: The law, the replay, the ledger

VAR is not a court. It is a procedure. The IFAB protocol permits intervention in only four categories — goal or no goal, penalty or no penalty, direct red card, and mistaken identity. An intervention is legitimate only when it corrects a "clear and obvious error" or a "serious missed incident." That definition is both VAR's weakest and its strongest point. Weak, because a threshold cannot be measured in numbers. Strong, because that same threshold protects the referee's decision — as long as the record of evidence stays clean.

In 2026, at the age of 52, I joined the Dhaka-based digital outlet KickOff Dhaka as its first VAR analyst. Over 24 Bangladesh Premier League matches I reviewed 120 incidents, logging each one under its rule, its camera angle, and its final call. I did not publish a single line before the Bangladesh Football Federation confirmed the outcome. Forty-five years of watching football on the ground taught me that the speed of a decision and the accuracy of a decision are two different things — and that newsrooms usually chase the first.

This is where the second layer of the data economy enters. Every live match now emits data by the second — passes, shot locations, positional tracking, refereeing decisions. The biggest buyer is the betting market. That market has a simple requirement: it cannot tolerate a blank cell. The match is running, so there must be an answer. Where the game pauses to think, the market cannot pause — and that impatience is the darkest edge of football's datafication.

Core analysis: what a single blank cell kills

I opened the ledger to see what the referee could not — but this time the ledger was empty. An empty ledger cannot be analysed. It can only be described.

Suppose a report arrives with no title, no source, no date, and not a single data point. The first casualty is not the content but the credibility. With the source field blank, you cannot establish whether the sentence in front of you came from a reporter at the ground or from an anonymous rumour line. In journalism, source is a mandatory field. In decision pipelines, it quietly becomes optional — and that optionality lets identical data be presented at two completely different levels of confidence.

The second casualty is classification. Match report, transfer rumour, tactical analysis, financial story, governance story — each has a different analytical centre of gravity. Without a type, you do not know where to apply pressure. What fills an unclassified template is not analysis. It is guesswork.

The third casualty is the most insidious. Every blank cell is attached, in reality, to a person, a club, a competition — to someone. When that cell travels downstream, no layer knows who is standing in front of it. No team, no coach, no governing body is ever held to account. A wrong decision can be tracked. A blank decision goes nowhere — it can be attributed to everyone, and therefore to no one.

This is where the question of a minimum-content gate arises. If a process receives fewer than three information points, or finds the title and the source blank at the same time, there is only one honest answer: stop, return a null, and state why. A reliable null is far more useful than an inflated analysis. But inside a betting-driven reality, that honesty is expensive. Pipelines hesitate to return nothing, and when they find nothing new, they lean on an old mould.

This is where the blockchain proposal becomes meaningful — though not in the way we usually imagine.

Picture a refereeing ledger. Each VAR review would be appended as a tamper-evident, searchable entry carrying a timestamp, hashes of the analogue video, the camera angle, the rule citation, and the final call. Nobody in Dhaka or anywhere else could later "correct" it. The league, the broadcaster, and the regulator would all read the same version. Who decided, when, and on what threshold would stop being a matter of argument. In close cases, that transparency would matter equally in the minute after full time and in the next day's broadcast cycle.

My thousands of hours of replay work point somewhere else. The monitor never lies, but the angle can omit the truth. In that France–Australia penalty there were six cameras — and an editor's hand choosing which one the audience saw. An immutable ledger can guarantee which pictures existed in the system and who viewed them at which moment. It cannot guarantee that those pictures answer the threshold question. Blockchain protects the archive. It does not deliver the verdict.

And if record-keeping and justice became the same thing, every old decision would be permanently correct. The result would be ruinous. A referee's most essential skill is composure; accuracy is the goal, not the condition. If a ledger froze old rulings and left a new generation only two paths — accept it, or accuse it of fraud — the conversation on the pitch would collapse entirely. The ability to remove error from history is also a strength of a civilisation. VAR itself has redefined "clear and obvious error" within a few years, redrawn the boundaries of handball interpretation, and shifted the standard for arm position inside the penalty area. Had those revisions been locked inside an immutable, unchangeable ledger, the law would have become not strict but inhuman.

Contrarian angle: the shape of a report is more dangerous than the report

Conventional honesty fails here. Some of us assume that when the data is empty, the decision panel will simply show empty cells. The opposite happens. Empty data often becomes an attractive graphic before it ever reaches the panel, and nobody looks at the film inside. This is my central worry: the real danger of content emptiness is not the emptiness but the confidence built on top of it — because a blank panel is easy to catch, and a beautiful panel is not.

Bangladeshi football journalism learned this lesson early, through its first big industry. Trying to understand why a daily sports paper gets printed at all, I understood that the speed of a decision and the basis of a decision are never the same thing. In recent years, most of the worst decisions in my own list came from matches in which the crowd demanded an instant answer. Most of the best came from matches where there were ten minutes of pause — because time had been allowed to reach the evidence.

A concrete case. In a 2026 Bangladesh Premier League match, a slight contact inside the penalty area was waved away and play continued. Players and broadcasters later called it a clear error. I went back through my list of 120 incidents and found that of seven comparable cases, five had seen the on-field decision left standing. Intervention came only where the images were genuinely untenable. That is not a verdict on good or bad refereeing; it is a faint signal of built-in consistency — an insight that would never have surfaced without a structured ledger.

Another thread. FIFA has been moving toward allowing more substitutions, from five toward six, seven, or ten. The change favours deep squads, but every substitution generates a fresh VAR question. The biggest effect of the substitute rules is not felt in midfield. It is felt in the referee's pocket. Because the best part of a good footballer becomes replaceable, and every replacement brings new physicality and new controversy into the penalty area. In that kind of football, keeping an accurate record stops being a luxury.

By the same logic, if I am the one who has to assemble the evidence around a disputed call, then an automatic check placed before publication is simpler and safer. A minimum-content standard could be built into any data-driven VAR report — one that refuses to render a panel when the underlying evidence is absent. I have seen a medical imaging recommendation model built with enormous care, and then the same model deployed where reviewers saw only the patient and the outcome, with no room at the entry gate to verify anything. Sport is not medicine, but the question of minimum diligence is identical: are you generating a report without realising it?

Takeaway: where the market never stops

I am arriving, slowly, at the view that the biggest shift in football governance over the next few years will come from a small change of habit — accepting a genuine "no" from the data. On a live broadcast we call a technical fault an interruption. In a justice system, the fault itself is information. Substitution rules have changed, risks have been debated, and yet we still bury system faults, because the audience raises a hand and asks the oldest question in the game: so who lost?

The cast changes from presidency to presidency, so a few questions will remain. Is everyone along the chain of evidence looking at the same pictures? Will the footage broadcast at full time and the footage never shown fall under any independent oversight? I will not turn into a man shouting from a well, but I want to end with one warning. Football is a republic; truth there is a public service, not a private identification — and without it, the story of who lost and the story of who stole will be printed on the same page.
