From the Scorebook's Margin to the Blockchain: In Search of Immutable Truth in Cricket Data

On October 12, 2026, in the scorers' box at the Sher-e-Bangla National Cricket Stadium in Mirpur, one afternoon is still stuck in my notebook. When the match ended, the score sent to the board's digital feed did not match one cell in my hand-written over-by-over log. A no-ball. Between what the television showed and what I counted, there was a one-delivery gap. Someone might say, what is one delivery? But that single cell written in the scorebook's margin told me that afternoon — cricket's truth never lives on the scoreboard; it lives in the margin. The margin note is where the match actually lives.

I hand-scored Dhaka and Sylhet fixtures for 26 years. In 2026, the board's digitisation drive made my unit redundant. Paper grids, red-and-blue pens, over-logs written in dim light — these were my office. When the digital feed arrived, many assumed hand-scoring was now history. My experience says the opposite. More data does not reduce truth; it changes truth's address. The question is: who verifies that new address?

In Bangladesh cricket, data now lives in three layers: the umpire's on-field decision, the broadcaster's graphics, and the board's database. There is no neutral witness coordinating the three. A ball's speed, a review, a run-out — every piece of information shifts as it moves from one hand to another. One number on the board's server, another on the broadcast graphic, a third in the media. If someone asks which is correct, there is no one left to answer. Here the question of data provenance and integrity arises — and here the word blockchain enters.

Blockchain's simple promise is this: once written, information cannot be changed. In the world of cricket data its value is immense — if we use it correctly. But before use, we must understand which part of cricket data genuinely needs to be immutable, and which should be left to human judgement.

Open my 2026 Russia World Cup file and you will see I coded 1,704 shots and 169 goals across 64 matches in my own xG model. My France file noted 40 percent possession in the semifinal against Belgium and six goals conceded across seven matches. Some said then that France were lucky. I wrote that the low block was structural, not lucky. Proving structure requires a source for every data point. And the cleanest way to prove a source is a ledger no one can quietly alter later.

Blockchain enters cricket mainly through three paths. First, player registration and contracts — if the Bangladesh Cricket Board keeps a player's date of birth, eligibility and contract information in an immutable ledger, old problems like age fraud shrink considerably. Second, match-data provenance — which bowling-action data came from which camera, who processed it, when it was altered; the whole chain can be recorded. Third, ticketing and fan engagement — this strikes directly at the black-market ticket and fake fan-token problem.

There is another layer many do not call data — the gap between official and non-official data. How many dot balls fell in a match, which over the field changed, how often a bowler lost his line — none of this reaches the broadcast. I saw a spinner bowl 23 consecutive dot balls in a night match in Sylhet, yet it never appeared on the graphic, because the camera's focus was on the batter and the scoreboard. Those 23 dot balls were the real story of the match. Silence has a box score; nobody simply prints it.

One more thing must be said. The camera sees men's cricket far more than women's. Ball-by-ball data for Bangladesh women's matches is stored far less than for men's. If a game is not even recorded, where do we look for its truth? If blockchain preserves only the data of televised matches, it will make invisibility permanent, not remove it. Among what I count are women's cricket, ground staff and scorers — all of them.

On this point, let me speak of young players. In 2026 I interviewed Soumya Sarkar, then a rising talent. Since then I have noticed that elite academies hoard talent, yet fewer than 10 percent of players get a genuine first-team path. If data sits in a transparent ledger, it becomes clear which academy truly builds players and which merely registers names. Hoarding talent and building talent are not the same.

Consider the transfer window too. Release clauses, agent commissions, age-based valuations — all of it drowns now in the noise of transfer rumours. Yet a real blockchain use exists here: recording contract terms and commission accounts immutably. There is no formula to measure dressing-room chemistry, but the numbers in a contract can be measured — and those numbers show who is genuinely an investment and who is merely a headline.

The real trap is here. When technology arrives, we assume the problem is over. But blockchain is not a truth-machine; it is a truth-preserving machine. The difference is vast. Before preserving, who determines the truth? If it is a board-controlled node, then the thing called decentralisation will exist on paper while centralised power exists in reality. This risk is not new in cricket administration. I have seen many times that whoever holds the information holds the power.

So my proposal is simple: use blockchain as a model, not an oracle. Cross-check it against hand-coded data — where they agree, place trust; where they disagree, that is the real story. In Abahani Limited Dhaka's 2026–18 season I coded 1,043 defensive actions across 24 matches; average PPDA was 8.4 in wins and 13.9 in draws. Those numbers came from no dashboard; they came from a notebook and an eye. If blockchain can make that notebook permanent, hand-scoring will not die — its testimony will survive.

One last word. The night shift is not a schedule; it is a confession — who works unseen, who gets credit. Technology can blur that confession, or sharpen it. A blank cell is not empty; it is waiting — waiting to be answered. I do not predict; I archive the conditions of prediction. In the next two or three years, blockchain's first real application in Bangladesh cricket may appear in ticketing or player registration, perhaps by 2026. But if that application is to be transparent, it first needs an independent audit layer, where hand-coded data is checked against machine data. Technology that runs without audit is merely another form of power. The question is therefore not whether Bangladesh cricket will adopt blockchain. The question is whether, before sitting on the blockchain, we are willing to clean our own scorebook.
