If the Scorecard Sits on a Blockchain: A Matchside Observer's Notes on Cricket Data Trust

Late one night last year, in the Sylhet Data Room, I was verifying a viral scorecard. A social-media post claimed a batsman had posted the highest strike rate in tournament history. It had been shared thousands of times; nobody in the comments asked a question. I opened the ball-by-ball data and started counting by hand. Three hours later it was clear: six balls had been dropped from the graphic, one over had been double-counted, and the strike rate was inflated by eight points. No one had made an accident. Someone had tossed out a number with no trace, and the crowd had turned it into truth.

That night I thought: if that viral image had been a scorecard whose every figure carried a locked birthplace, a timestamp, and a record of who typed it when, the argument would have ended at the data layer. And it is exactly here that blockchain is knocking on cricket's door.

Blockchain is simple in cricket's language. Imagine an open ledger that no single person can write alone. Each entry, once made, becomes a cryptographic fingerprint — a hash — chained to the entry before it. If someone wants to alter an old number, they must change every subsequent hash, and the tampering shows the moment it fails to match every other copy on the network. The bottom line: the data and its history cannot be separated.

It is entering cricket through several doors. In 2026, Cricket Australia launched its own NFT platform called Crictos, where match moments are sold as digital collectibles. In 2026, the Indian platform FanCraze announced a partnership with the ICC and that same year raised 100 million dollars, staking a large claim in the cricket-collectibles market. Beyond that, fan tokens, smart-contract ticketing, and player-payment trials in a few T20 leagues are all underway.

But my interest is not in collectibles or token prices. My interest is in the one place where blockchain can genuinely matter: the authenticity of scorecards and the auditability of match data. Because cricket's real crisis is not a shortage of data; it is the credibility of data.

When I joined The Daily Star's sports desk in 2026, I first learned that before a number goes to print, you must know its source. That lesson peaked in Cardiff in 2026. A new-media outlet wanted a quick Champions League final preview. I dropped the deadline and hand-coded all 1,024 passes from Real Madrid's 4-1 win. Of Ronaldo's six shots, three were on target, and Madrid's PPDA was 12.4 — all placed in a seventeen-column spreadsheet. The thread went out six hours late, but it went viral. I named the project the Sylhet Data Room.

I hand-coded 1,024 passes in Cardiff before I trusted a single dashboard. Because the Sylhet Data Room began with one notebook, one modem, and a stubborn refusal to guess.

That stubbornness is what makes me wary about blockchain today. What blockchain offers is immutability. But cricket's problem is often not alteration; it is faulty input. If someone enters data during a match and mistakenly types a boundary as a four, blockchain will sanctify that error forever. A hash proves the data has not changed; it does not prove the data was right to begin with.

Take a blockchain-based scorecard system. After every ball, the scorer makes an entry; it sits in a block, gets a timestamp, gets a hash. At day's end, if someone claims an over count was wrong, we can scan the whole chain and see who wrote what when, and who corrected it. DRS review logs, third-umpire decisions, even every frame of ball-tracking data — placed on an immutable ledger, the anti-corruption unit's job in match-fixing investigations would become far easier. Today, an investigation often rests on a few emails and one Excel file with no audit trail.

Another area is player workload. I have long written about the burden of fifty-plus franchise matches and the elevated risk of muscle injury. If a league placed every ball, every spell, every travel day on an immutable ledger, boards and physios could sit in one place and see who is carrying how much load. Working on Bangladesh's bowling unit, I have seen that with bowlers like Shakib Al Hasan or Mustafizur Rahman we often work on estimates, because the data is scattered across five separate systems. A shared ledger could bind that scattered information into one truth — on one condition: the input must be accurate.

But as a model-builder, I know that in praising technology we often skip a step — the step of verification. In 2026, I built a 64-match xG bracket, coded 1,024 shots and 169 goals, and derived each team's PPDA. France averaged 0.98 xG per match; Croatia, 1.42. I calmly published a bracket giving France a 54% final win probability. France won 4-2. When the 64-match xG bracket called France, I learned models can be quiet prophets. But I learned something else: the model was right because the input was right. When the input rots, the model simply becomes a confident error.

This is blockchain's limit. A hash verifies integrity, not truth. Cricket's problem is garbage-in, garbage-out. If someone at the boundary types a wrong score, blockchain will immortalize the error, not fix it. The danger can even grow: people will think, 'It is on the blockchain, so it must be true.' Conflating immutability with truth is the biggest trap of all.

So my proposal is to step back one stage. Start blockchain not at the far end but at the near end — at the moment of data entry. Attach to each entry the identity of the enterer, the time, and the source — whether the scorer saw it in person or took it from the TV feed. Then, when we audit, we know a number's lineage.

Another practical dimension is cost and speed. Writing thousands of transactions per second on a public chain raises fees and latency; live ball-by-ball updates during a running match become a problem. Many franchises will therefore choose a private or permissioned chain with a limited set of validators. But in a permissioned chain, power recentralizes, and we return to the old question: who guards this ledger? Blockchain's original promise was decentralization; cricket's reality is boards, leagues, and broadcasters — three powers.

Let me be clear about fan tokens. When a league sells tokens, fans believe they are getting a share in decisions. But in most cases the token grants a voting right with almost no real weight, because final decisions are made in the boardroom, not on-chain. Data truth and governance power are two different things, and blockchain can help with the first, not the second.

Smart-contract ticketing has a real benefit. If ticket ownership lives on-chain, scalping can be reduced, because no one can resell a ticket at a price the contract does not allow, and every transfer is recorded. At major cricket tournaments where tickets sell on the black market at three times face value, this is not small — it is a big change.

I know that hearing me now, some will say I am anti-technology. That is not the point. I simply refuse to mistake correlation for causation. If the rise of blockchain and a fall in cricket corruption happen together, some will say blockchain stopped the corruption. But I also watch the off-field variables — the greater evidence in investigators' hands in the social-media era, stricter betting-market surveillance, growing broadcast transparency. These work together. Without evidence, I will not credit blockchain.

The empty stadiums of 2026 taught me that atmosphere is a variable, not a verdict. Likewise, blockchain is a tool, not a solution. In an organization that does not train people in data entry, that does not build a culture of verification, blockchain is just an expensive veneer. Technology and trust are two different layers, and the first is no substitute for the second.

My next step is clear. I am starting a small experiment in the Sylhet Data Room: I will log ball-by-ball data from an under-19 tournament on a permissioned chain, attaching to each entry the enterer's identity and the time. Six months later I will see what the system says when someone tries to change a number. At 59, I still hand-code, because trust is a manual process. Blockchain can give me a new ledger; but the first entry in that ledger is mine to get right.
