The Blank Cell's Testimony: Cricket Data Integrity and the Blockchain Ledger

Last night in Sylhet I opened a file at my desk. The filename read: Stage-2 Deep Analysis, Cricket. Inside were eight sections, six tables, one transmission map. And in almost every cell, the same sentence: insufficient information, cannot assess. The information-point list was blank. The title was blank. The source was blank. The author's position was blank. One cell alone was filled — the domain label: cricket_asia.

The easy move was to fill those cells with imagination. Drop in a name, drop in a score, build a tidy little story. But twenty-six years of hand-scoring scorebooks in Dhaka and Sylhet taught me one habit: you do not run a pen through a blank cell. A blank cell is not empty; it is waiting. This article is the accounting of that wait.

The blank-cell problem is not mine alone. It is the central problem of Bangladesh's cricket data, and nobody sees it from the boundary.

In 2026 the BCB's digitisation drive abolished my unit. After twenty-six years of hand-scoring, I was told the paper era was over. The paper was not over. What ended was the habit of writing a margin note beside every ball — the bowler's footmark, the wicketkeeper's angle, which line the previous delivery before the no-ball took. The margin note is where the match actually lives. A digital scoreboard has no space for that margin.

The real question now is who holds the data, who can verify it, and how anyone would notice if it were quietly changed. In domestic cricket those three questions rarely have answers. The score lands in a spreadsheet, then nobody knows where it goes. Betting markets, fantasy leagues, broadcast graphics — all of them lean on the same number, and none of them carry a seal proving where that number came from.

That gap is what gave birth to the blockchain conversation. The idea is simple: if every delivery, every run, every wicket is written to a timestamped, immutable ledger, nobody can rewrite the result later. The transfer window is a ledger, not a soap opera — and the same holds for a cricket scorecard.

Now to the real question. What does blockchain actually solve, and what does it not?

Consider how many hands a single ODI's data passes through before it reaches your screen. The ground scorer writes it. The match referee reconciles it. The host broadcaster's data operator types it. Then it travels to the ICC feed, then to a stats provider, then to the press. At each step a number can shift, deliberately or by accident. In domestic leagues those steps are far murkier.

Blockchain's proposal is this: each step's entry is hashed separately, and each entry is chained to the one before. Anyone trying to change a single run breaks the chain, and it shows immediately.

It sounds clean. But I am a hand-coder, so I want the grid drawn out.

| Layer | What is recorded | Who writes it | How it is verified | |---|---|---|---| | Ball-by-ball | Runs, wickets, extras | Ground scorer | Timestamp | | Positioning | Field placement, footmarks | Coding analyst | Hash match | | Referee | DRS decisions, penalties | Match referee | Signature | | Broadcast | Graphics, over-rate | Data operator | Feed cross-check |

In the 2026-18 season, across Abahani Limited Dhaka's title-winning campaign, I hand-coded 1,043 defensive actions from 24 matches. Average PPDA in wins was 8.4; in draws, 13.9. Producing that number meant stopping each match's footage ball by ball and counting. If someone later claimed Abahani pressed higher that season, I had the defensive record to answer with.

But where did that record live? On my laptop. In a file. Anyone with the will could have changed it. This is exactly where the blockchain argument is strongest. It does not end the argument; it makes the evidence of the argument immutable.

What I counted needs a permanent address.

How the work was done matters too. I wrote every match's over-by-over log on paper first, then transferred it to the laptop. How often the opposition's defensive line broke in an over, how often the ball went to the wing-back — those small cells later built a large picture. Read individually they say nothing. Read together they reveal which overs carried pressure and which merely circulated the ball.

In 2026, while at The Daily Star, I interviewed Soumya Sarkar. He was rising then. That day I learned that a young player's development is not measured in runs alone — which matches he batted under pressure, where he was weak against which bowler, all of that deserves recording. But where does that record live? Almost nowhere.

Take one example. If an under-19 or under-16 pace bowler's speed, line and length had sat in a verifiable ledger from the start, academies could not hoard a talent for years and negotiate for their own advantage. The record of a player's development would sit in the player's own hands.

Think about DRS too. Ball-tracking is itself a model — with its own assumptions and its own limits. Pitch angle, ball rotation, seam position: the model makes a decision the spectator never sees. If that model's input and output sat in separate ledgers, the decision could be questioned. Today we see only the verdict, never the method.

Look at the data economy as well. Franchise leagues, fantasy platforms, broadcasters — all buy the same data. Who owns it, who sells it, who merely uses it: in domestic cricket those lines barely exist. A blockchain-based registry can help draw them. It cannot decide ownership for you.

Betting markets matter here too. If a domestic score is known in advance, or altered afterwards, trust in that market collapses. The simplest way to remove suspicion is an open, timestamped record anyone can verify. That is blockchain's most usable proposal.

In 2026 BDCricTime won the BASIS National ICT Award. The award mattered because it proved standards-compliant work on domestic cricket data is possible. But even after the award the question stands: where is that data stored, and who answers for it?

I keep one working rule. Hand-counted numbers and model numbers are used as two separate scorers. When they agree, good. When they disagree, I publish that too. A chain makes the second scorer's job easier — because the divergence between two entries becomes visible.

Now the part where I argue against my own case.

Blockchain does not fix bad data. If a wrong number goes on-chain, it becomes immortal. To make change impossible is to make correction impossible. Wrong scores are routine in domestic cricket — otherwise match referees would not keep correction lists. Where is the space for those corrections in an immutable ledger?

Second, a timestamp proves when something was written, not that it was written truthfully. Someone who was never at the ground can still push a wrong number onto the chain, and it will sit there forever as evidence.

Third, the loudest voices around this technology are the ones who have never held a scorebook. Fan tokens, NFT moments, imaginary ownership — their relationship to the truth of the field is close to zero. I want numbers, not slogans.

I do not predict; I archive the conditions of prediction. A chain can preserve the conditions. But the conditions have to be made on the ground, on paper, in human hands.

So what should you watch in the next round?

I will watch which domestic cricket body publishes its data first, and whether it releases it in a verifiable format. No token, no slogan — just a filled blank cell. Because the blank cell was our real problem all along, and it asks for testimony before it asks for blockchain.
