Blockchain Ledgers and Rain-Soaked Scorebooks: Who Keeps Bangladesh's Age-Group Cricket Archive?

July 2026. Water still pools at the northern edge of Rajshahi College ground, mud along the boundary rope. Before an under-16 championship match was abandoned, the scorer had written eight overs into a yellow notebook — pencil scratches, two crossings-out, damp fingerprints on the edge. A left-arm slow left-armer. Just before release the elbow drops a fraction late, the ball starts outside off and bends in. Four wickets in those eight overs, one maiden. The notebook is now at the bottom of someone's drawer, or perhaps simply lost.

I came for the highlight; I stayed for the sediment. A highlight is tracked by a camera; sediment is tracked by a notebook — and in Bangladesh's age-group cricket, a notebook means risk.

The empty stadium taught me that silence, too, has a shape. That rainy day, nobody was in the Rajshahi galleries; the scorer, two coaches, three or four parents and one journalist — roughly seven people. The match was abandoned. Seven people went home. A performance was erased from history. The question is not only who won; the question is where those eight overs will live.

This piece begins from that question, and in looking for an answer I ended up somewhere strange: blockchain.

Context: the archive we do not have

Bangladesh's domestic and age-group cricket suffers less from a shortage of talent than from a shortage of documentation. Below the Dhaka leagues, across divisional under-16 and under-18 sides, in age-group women's teams, ball-by-ball data is close to nonexistent. What exists is scattered: a notebook with the scorer, a phone photo in a coach's gallery, a match report in an old newspaper edition. Three places, three versions, and nowhere a way to verify.

When I started a blog called Youth Trench from Rajshahi in 2026, the core task was digitising exactly this loose paper. Digitising the 2026 under-16 championship tapes, I found the same bowler's pace reading differently across two tapes — because in one the camera sat beside the stand, in the other beneath the scoreboard. Change the perspective and the data changes. But if the notebook is lost, the data is gone; perspective does not even enter the conversation.

After joining as one of the BCB's digital and media advisors in 2026, I saw more clearly that the problem is not a lack of technology. It is a question of ownership. Who keeps the record, who verifies it, and who answers when someone writes it down wrong.

The basic idea of a blockchain is relevant here. A ledger where every entry is timestamped and linked to a cryptographic hash of the previous entry. To alter an entry later, every subsequent hash must change, which exposes the tampering. There are two implementations. A public chain, readable by anyone. And a permissioned chain, where write access belongs to a set of verified nodes — a host board, a match referee, the coaches of both sides.

For Bangladesh, the second fits better than the first. Injury data, family information and medical records are not for public display. If you want transparency and privacy together, a permissioned ledger is the only route.

Core analysis: what actually goes on the ledger

The first layer is basic scoring. Ball-by-ball data: which bowler, which over, which line and length, the batter's footwork, the direction of the shot. This layer is relatively easy, since scoring software already exists. What the ledger adds is one thing — time. With a timestamp on every ball, you can tell whether the data was captured live or written up the next day from memory. In age-group cricket that distinction is enormous.

The second layer matters more, and is more uncomfortable: age verification. A birth certificate, a school record, a medical report — hashing these three together puts a verifiable imprint on the ledger. The original documents stay secure elsewhere; only the imprint is public. Change a date of birth and it shows. I want to be explicit: blockchain will not stop age fraud, because the fraud happens at the point of document creation, on paper. But it raises the cost of the fraud and leaves a permanent question mark on a player's career that scouts can later see.

The third layer: an injury and workload ledger. In my view fixture congestion is the single biggest cause of injury — no medical team can absorb the load of two matches a week. If the ledger holds each bowler's over count, spell length, rest between spells and injury history, a selector or coach can see, before calling up a name, how many balls that boy has bowled in six weeks. Today nobody has that information. Every bowler is exposed to fresh risk because the old risk was never recorded.

The fourth layer is the most contentious: coach evaluations. 'This boy has good commitment', 'he breaks under pressure', 'he cannot fit into a team environment' — all subjective, and all the most damaging, precisely because they are never written down and therefore never challenged. The ledger's job here is not to declare information true. Its job is to fix who gave the assessment, when, and in what context. If a 'breaks under pressure' note from four years ago sits beside a match-winning innings today, no one can claim the assessment never existed.

Cost, infrastructure and ownership

Now to practicalities. To make ledger entries at a district ground you need a smartphone, internet, and a trained scorer. Where there is no internet, entries can be made offline and synced later — an essential feature for Bangladesh, where networks at many grounds are unreliable.

The real question is ownership. If the ledger sits on a BCB server, it is a centralised database wearing a blockchain label, and the board can intervene whenever it wants. If the ledger is fully decentralised, the data is protected but nobody is accountable — if someone enters it wrong, who answers?

My view is that the right design is in between: three verified nodes — the district association, the host committee and the BCB development wing — each with a separate key. All three enter the match score independently; if they match, the entry is final. If they do not, the ledger flags a dispute for humans to review. That brings transparency and shrinks the room for dodging responsibility.

One more thing belongs here: player consent. A 15-year-old's injury record, family finances or school information — who may see it should be known to his family. Read permissions can be tiered on a ledger. Without that control, data protection law is at risk, and the liability lands on the board.

Transparency in selection

Complaints about selection in Bangladesh cricket are old. A large part of them comes not from a lack of knowledge but from a lack of information — no record of who was dropped, why, or what the dropped boy did last season. If every age-group camp performance sat permanently on a ledger, at least the argument would have a foundation.

But I want to be careful here. Transparency is not justice. With data available, a selector can still make a mistake — but at least there is evidence. And that is the limit of this argument: blockchain does not improve the quality of a decision, it proves that the decision existed.

Contrarian angle: what blockchain will not fix

Now the part where I have to stand against my own enthusiasm.

First — blockchain will not fix scouting. The bottleneck in scouting is people, not technology. If a scout does not go to the ground, if he cannot sit four hours on a bus on a rainy day, the world's best ledger will not find a boy. What technology can do is stop the information of a boy already found from being lost.

Second — if the data is wrong, the ledger makes the wrongness immortal. Garbage in, garbage out — only this time the garbage is cryptographically secured. If a coach writes a biased review, the ledger preserves it forever rather than correcting it.

Third, and most important — fan tokens and player archives are not the same thing. In Bangladesh, mention blockchain in cricket and everyone thinks fan tokens, NFTs, digital collectibles. These put a fan's feeling on the market but add nothing to a player's development. Every transfer fee is a lid; under it, a childhood. A fan token makes that lid heavier, not lighter.

Fourth — blockchain's biggest enemy is blockchain hype. If a district association thinks 'blockchain means money', the consultant fees will arrive and the ledger entries will not. When Rajshahi Silk City FC withdrew from the Bangladesh Championship League over funding in 2026, I learned that nobody steps away because infrastructure is missing; they step away because the arithmetic does not add up. The same logic holds here. Before rolling out a chain, ask: will you pay the scorer 200 taka per match?

Toward a verdict

So what should be done? I would propose three layers. First, mandatory digital scoring for all under-16 and under-18 matches in Dhaka and the four divisional cities, maturing into a permanent ledger over the next three seasons. Second, mandatory injury and bowling workload data — because the only intelligent way to reduce fixture load is to measure it. Third, keep all fan-token style projects separate; their relationship to player development data is zero.

What is the measure of success? Not trophies. The measure is this: if five years from now someone can retrieve the four wickets taken in that 2026 Rajshahi match, and can prove the data was captured live, then the job has been done.

I do not know that left-arm spinner's name. Perhaps he is in another profession now. Perhaps he still bowls, on some small-town ground with no scorer, no notebook, and cameras far out of the question. The question is not about him. The question is about the next one — the boy who bowls this evening, whose eight overs will be written down nowhere.

Will we build the means to write him down, or let another notebook be lost?
