Blockchain and Cricket's Data Integrity: The Replay Nobody Saves

The 27th over of the match. A DRS review is underway. The stadium is pin-drop silent. The third umpire stares at the screen as ball-tracking shows the ball striking the pad exactly how far inside. Sitting before the TV, I wondered — who actually preserves this frame? If, six months later, someone asks how this decision was made, where will the answer live? The truth usually hides in the frame before the frame, and that frame is the least preserved of all. I replayed it eleven times before I trusted my own eyes — but it took me years to realise that nobody saves the replay. I write about cricket's VAR and DRS from Sylhet. Doing this work, I have noticed something strange: we argue about results, but few lose sleep over the data behind the decisions. Ball-tracking, UltraEdge, snicko-meter — these technologies generate millions of data points every match. Yet there is no single account of who owns this data, who verifies it, or who preserves it. This is where blockchain becomes relevant — right at the point where the game, technology, and economics meet. The International Cricket Council (ICC) has made DRS mandatory in every major tournament. Hawk-Eye, UltraEdge, real-time snicko — these systems support the umpire's decision, but a human makes the final call. Watching the first VAR penalty at the 2026 Russia World Cup, I understood that when technology decides, a kind of helplessness settles over the crowd. In cricket that helplessness is sharper, because the ball's trajectory, spin, and bounce are all measured in millimetres and milliseconds. The problem is that these measurements usually sit behind closed doors. Broadcaster, board, and technology provider — the data is scattered across three parties. No single party can verify the whole picture. That gap is blockchain's entry point. Blockchain is a kind of digital ledger where every entry becomes immutable over time. Once written, no one can erase or alter it. Cricket is now beginning to discuss its possible uses — DRS review logs, player contracts, fan tokens, and NFT collectibles of match moments. The idea is simple: if every decision has a verifiable record, later disputes will shrink. But this is where I stop. Because my experience says cricket's problems are often not a lack of technology, but the misuse of technology. I once wrote a great deal about football's xG. xG is a good metric, but people use it as if it can explain a player's mind, form, and the umpire's verdict all at once. When a metric does not answer the question, we change the question. Blockchain carries the same danger. What blockchain can do is prove authenticity — giving immutable timestamps to when data was created and by whom. Smart contracts can automate player payments, bonuses, even ticket distribution. Through fan tokens, spectators can vote on club decisions — though how much power that vote really carries is a separate question. In IPL or Bangladesh Premier League auctions, crores of taka now change hands. A transparent record of every bid and every contract creates protection for boards, players, and agents alike. Whether a player received their dues on time, whether bonus conditions were met — smart contracts can answer these questions. In South Asian cricket this is no small matter, because young players often cannot grasp the fine print of a contract. But what blockchain cannot do is pass judgment. It keeps the ledger; it does not judge. Whether the ball was inside the line, technology can tell; but what the bowler was thinking in that moment, why the umpire hesitated, why the crowd roared — none of that reaches any laser. The whistle decides the match, and the replay decides the whistle — but the person sitting behind the replay, their doubt, their fatigue, their courage, is written on no chain. This is my real objection. Blockchain can raise cricket's data integrity, but it cannot measure the human part of the game. I do not hunt for guilt; I hunt for the angle nobody chose. When I watch Bangladesh Premier League footage frame by frame in my little Sylhet studio, I understand — technology only gives me information; I still have to make the decision. Blockchain can keep the record of that decision, but the responsibility stays with people. Yet I am not dismissing blockchain's potential. Suppose every delivery of an Under-19 match were stored on a blockchain. A decade later, when that bowler rises to the national team, their early form, injury history, bowling load — all verifiable. This transparency can protect young players, especially in the South Asian market, where young talent is often valued amid rumour and pressure. Likewise, when someone is accused of match-fixing or corruption, an immutable record makes investigation easier. Here blockchain can become a tool of ethics — if used correctly. For Bangladesh, this discussion carries extra weight. Our cricket economy is changing fast. Franchise leagues, sponsorship, social media — together, cricket is now not just a game but an investment. In this market, transparency means not just following rules but building trust. And trust is the real currency of this game. Tell me, when did you last see the full data of a DRS decision? Probably never. We only see the final verdict — out or not out. But the millimetres, frame-rate, and sound-sync behind it never reach us. Blockchain could open that door, if boards and broadcasters agree to share data. And that is the real obstacle — not technical, but political. Whoever owns the data does not want to let go of the power. The ICC, the BCB, broadcasters — each runs on its own interest. Blockchain means decentralising power, and no one gives up power easily. So I say, blockchain will not save cricket. A culture of taking responsibility for decisions will. Technology can only be the tool of that culture. Six years ago I made a wrong offside decision, and it took me three weeks to accept it. Now I think: if there had been an immutable record of that day's footage, would my error have been caught faster? Perhaps. But technology would not have given me the courage to admit my mistake; I had to find that myself. In the next five years, I expect at least one major cricket board to begin storing part of its DRS-related data on a blockchain. Perhaps it will start with fan tokens, perhaps with ticketing. But the real test will be something different — will we learn to see the angle nobody chose? The game ends in a result, but truth ends in accountability.
