The Ledger and the River: Blockchain, the Stopwatch, and Bangladesh's Lost Swimming Records

At first light on the Shitalakshya ghat the water turns the colour of brass. The boats have not yet lifted anchor; an old swimmer sitting on the steps wrings out his gamchha. I open my notebook, write the date, and write the same line I have been writing for thirty years — who swam, in which river, at which ghat, from whom they learned, and who caught their time. I trust this writing because it is my only asset. What the stopwatch says is truth to me. But tonight I sit with a different ledger in mind — one that no one can erase, no one can alter, and which stays open to everyone. People call it a blockchain. I would rather call it the river's account book, the one that never forgets.

I took the swimming beat nobody in Bangladeshi sports media wanted. In 2026, at the fifth SAF Games in Dhaka, the television commentator fell ill and a producer put a microphone in my hand. That day I called a Bangladeshi breaststroker as finishing third; he had finished fourth, and the groan travelled across the deck. That night I sat in the stands asking strangers what they had actually seen, then spent a month with VHS tapes and a notebook. From that month I kept a lane card for every swimmer — district, river, coach, personal best — and stopped calling a placing before the touchpad confirmed it.

That lane card was my first blockchain. Each line was a block, each date a timestamp, my signature the chain that bound one line to the last. The difference is that my notebook can be lost, torn, or washed clean by monsoon rain. To a man standing at the water's edge, that fragility was the great enemy. And when I think about blockchain today, I am really searching for an answer to that fragile notebook.

The empty ledger: a record with no witness

Last month a young colleague showed me an analytical document — a deep framework on swimming with nine dimensions, each with tables, coordinates, risk matrices. Every cell was blank. No title, no information points, no names, no dates. Each box read 'insufficient information.' My colleague laughed and called it a failure. I said no — it is a truth. It is the true portrait of Bangladeshi swimming. We have no analysis because we have no data. We have no data because we have no ledger.

Imagine a nation's swimming history, its best times, its best swimmers, their rise and fall, scattered district to district, in different notebooks, in different handwritings, some only by word of mouth. In 2026 Mosharraf Hossain crossed the English Channel. Then in 2026 came the Sagor–Himel relay — that thirty-seven-year gap is stored nowhere in a library; it lives in a few memories and a few torn newspaper pages. If that gap had been written in an inevitable ledger, could we have sat silent for thirty-seven years? I do not think so.

A lack of information is never only a lack of information — it is a lack of memory, and a lack of memory is a lack of accountability. A nation that forgets its own record also forgets the duty to break it. So the greatest promise of blockchain to me is not a coin, not a fan token — it is un-erasable memory. A running sum, added to daily, that no single person can alter.

What the ghat taught me about verification

In 2026 I asked to cover the National Long-Distance race, roughly ten kilometres down the Shitalakshya. No grandstand, no scoreboard, no touchpad — only a line of heads in brown water and spectators on the chars. I called it from a country boat with a borrowed megaphone, and midway I stopped describing positions and started writing what ten kilometres of river does to a body.

Afterwards I sat with a village swimming instructor who counted the children her union had lost that monsoon. Hearing that number, all the pool's touchpads, all the electronic timing, all the supposedly perfect measurement felt meaningless. Those drowned children have no record. They are not part of any ledger. Who will write their names? Which system will timestamp them?

The most important verification in swimming does not happen on the stopwatch but at the ghat — who is watching, who is witnessing, and where that testimony is stored. A time becomes true only when there is a witness who can independently check it. This is the essence of blockchain: if one node lies, a thousand others catch it. At the river's edge that was the oldest rule of all: if ten people from ten ghats say the same thing, the likelihood that it is true rises sharply.

I have long begun every river-race broadcast with one drowning fact and one family's name. This is not decoration; it is evidence — so the viewer understands that beyond this pool there is a delta where these records serve no one.

The stopwatch: Bangladesh's first decentralised ledger

People think blockchain arrived with Bitcoin. To me, the idea is as old as the stopwatch. A stopwatch is a contract — everyone agrees that this instrument's time is the truth, that it is nobody's father's property, that it does not stop for anyone or run fast for anyone. Like it or not, 58.47 seconds means 58.47 seconds.

Inside that indifference lies a democracy. Blockchain does the same — it does not know your identity, it does not know your story, it only reconciles the previous block's hash with the next transaction. The world record ledger works the same way. FINA does not recognise a world record because someone said so, but because the time came up under a defined protocol, before a defined panel, on a defined timing system. That is a kind of consensus algorithm.

Bangladesh's real swimming crisis is not fake records — it is that there are almost no records at all. A perfect ledger, if empty, is worthless for being perfect. That is what I told my colleague. We are about to build a ledger in which there is nothing to write.

The gaps in the data: four decades of arithmetic

I have been on this beat for 38 years. What I have seen at the National Championship is not a medal table but a diagnosis. Navy first, Army second, BKSP third. This is no coincidence. It means our civilian club system is nearly empty. Someone could call it the Navy's fault, but I would say otherwise — the Navy has produced our national champions, and that deserves credit. The question is why a pipeline that can make national champions is not everywhere in the country. Why can a civilian club not do the same work?

When an army swimmer wins, it is their victory, but for a country it is a question — why did everyone else fall behind. We do not seek that answer, because the medal table blinds us.

In Mirpur there is one old outdoor pool. One. It cannot serve one hundred and seventy million people. Universality place after universality place, four decades of the same story. There is not one swimmer who qualified on merit. I keep writing that sentence in different words because it has not changed.

Now imagine every ghat in every district feeding its results into one public ledger. How many children learned to swim in which district, which coach produced how many, which village girl crossed both the social barrier and the water — if all of this sat timestamped in an immutable ledger, then at budget time it could no longer be hidden which district a minister neglected.

What blockchain actually is: arithmetic, not ornament

I am not a technologist; I am a commentator. So I explain blockchain simply. It is a kind of ledger whose every page is mathematically bound to the last. To change an old page you would have to change every page after it — practically impossible, because copies exist on thousands of computers and nothing survives without consensus.

Three of its properties match my profession directly. First, immutability — what is written cannot be erased; my notebook's greatest flaw was that monsoon rain washed the ink away with the memory. Second, timestamping — every event's time is permanently fixed, so the gap between 'I think' and 'my notes say' closes. Third, transparency — anyone, anytime, can reconcile every prior line.

Blockchain does not create truth — blockchain keeps truth. That distinction matters. Who supplies what is written? The ledger is blind. A blockchain cannot look into a pool, cannot know whether a swimmer's hand touched the pad. Someone must tell it. That someone is called, in the language of technology, an oracle.

And here is my real point. In swimming the oracle is the stopwatch, and in our country the oracle is often a human — pencil in hand, sitting by the river. Build the finest ledger you like; if the oracle lies, the ledger stores the lie. The gap between the instrument and the water is the centre of the whole problem.

Anti-doping: where blockchain's biggest opening lies

I always say credibility is the only asset this beat ever gave me. Staying honest with the stopwatch is the only reason my words carry weight. On doping, that honesty becomes harder.

Picture an anti-doping sample's journey. Who collected it, when, in which bottle, where it was sent, who tested it, who saw the result, who stored it — if every step carried a timestamped, public, unalterable entry, then when a charge is raised no one could say 'the paperwork cannot be found.'

Blockchain here does not create suspicion against anyone. The opposite. The more transparent a procedure, the greater the protection for an innocent swimmer. Where a doping charge is raised, if every step of the chain of custody is stored, imagine how much easier innocence becomes to prove. Over three decades I have watched many innocent athletes suffer for want of a document. That suffering is created by the absence of a ledger.

Let me be clear — I am naming no one and suspecting no one. I am only saying that absence of information is never proof, and the presence of information is an innocent person's best friend.

Splits, time, and thirty-seven years of silence

Swimming is a peculiar sport because time is relentless. In other sports you can stop and start again. Here, if you stop, everything ends. A 50-metre freestyle has ten splits, and each split tells a story — who started fast, who held the finish, whose shoulders tired mid-race.

That split data barely exists in Bangladesh. We know who finished first, and some of us know the second's time. Yet the real meat of analysis lies in those mid-race splits. A swimmer's split decline says more than their rise and fall. My notebook holds years of splits, but they are written by one man in a boat, scattered and unsaved.

From Mosharraf Hossain to Sagor–Himel — if those thirty-seven years sat in a shared ledger, we could see how much stagnation there was and where speed returned. We could see whether, after 2026, the number of swimmers fell or rose, or whether only the attention fell. That silence of time is not emotion; it is an accounting failure.

A nation that does not keep its splits does not understand its speed; and one that does not understand its speed never learns to be fast. Blockchain offers a simple but powerful proposal here — every meet, every lane, every split, once written, stays before everyone forever. Analysts would argue over it, coaches would plan with it, and no administrator could ever again say, 'I cannot find the record.'

The Navy pipeline and the civilian void

I do not wish to call the Navy negligent. The opposite — their training, discipline and continuity have repeatedly made our national champions. Camps, coaches, nutrition, medicine — almost everything a swimmer needs sits inside the cantonment. The problem is why that system cannot spread outside.

When a private club teaches a child to swim, it has no roof, no warm water, no physiotherapist. This is an unequal fight. Talent cannot be found, because talent is born in the districts, and in the districts there is no ledger, no club, no coach.

The Navy's success is really a mirror — a mirror that shows us that the system is absent everywhere else. If we are willing to look into that mirror, we will understand the problem is not a shortage of talent but a shortage of infrastructure.

And part of that infrastructure can be information. You may think blockchain does not build a pool. True, it does not. But you may not have thought — a clear, public record can show which district produces no swimmers, and why. To ask for a budget you need evidence, and evidence means a ledger.

Open water: where Bangladesh's real identity lives

I say it again and again — not the Mirpur pool, but the ten-kilometre long-distance race on the Shitalakshya or Dhaleshwari is the most authentically Bangladeshi swimming event. No grandstand, no scoreboard, no touchpad — only a line, and people standing on the bank.

Brojen Das crossed the English Channel six times, and his preparation happened in the Buriganga. That is no accident — it is proof that the people of this delta are tied to water by birth. If we accept our real identity, open water becomes our stage and the pool only our preparation room.

Measuring open water is hard. Current, waves, river bends, mud — together they mean the time is sometimes not as precise as a pool's. Here a ledger's value rises further. If GPS tracks, the boat judge's notes, the witness's record on the ghat — all feed into one ledger, then open-water racing becomes a fair, verifiable event. What exists now is ambiguity, and ambiguity always leaves room for dispute.

Open-water swimming is where Bangladesh can take on the world — if we can make our records trustworthy. Trustworthiness can be technology's gift, but the closeness to water is our own.

Swimming is survival infrastructure

I came to this beat for records, but I stayed for one reason — in this country roughly forty children drown every day. Forty. Every day. This is not a statistic; it is a national loss with no grandstand, no commentary, no medal.

When I write that number I do not mourn over a figure; I point at a system. SwimSafe-style programmes, rural instructors, floating safety in schools — if each sat in a timestamped ledger, we would know how many children learned in which union and where none has yet learned. That ledger is the strongest argument for a budget.

Blockchain's most humane use may not be a token but the testimony of how many children in a district learned to swim. If a drowned child's name at least sits in an immutable ledger, then at least this remains for their family — they were not forgotten.

Think of the village girl who must cross both the fear of water and the barrier of society. Two enemies stand before her — the river and prejudice. If every step of her training were written in a transparent ledger, her progress would not depend on anyone's word. That transparency is technology's greatest gift to her.

The contrarian side: a ledger cannot swim

Now the most uncomfortable thing I have to say. I praise blockchain, but I do not want it to become another mirage — the old dream where we get a new thing and think every problem is solved.

I have heard the word 'world-class' many times in my life. World-class aquatic centre, world-class league, world-class facilities. They live on paper, in budgets, in motivational speeches — while in reality the sun gets in a swimmer's eyes at one outdoor pool and a grandstand sits empty. If blockchain enters that paper list, it becomes another empty promise.

A perfect ledger does not solve the problem of an empty pool — it only makes the problem clearer. That clarity is good, but clarity is not solution. If I build a perfect ledger today showing how many children in each district cannot swim, I have only made our failure's arithmetic more precise. That is needed, but it is not enough.

The second danger is the oracle problem I mentioned. If the person gathering data at the river's edge is himself biased, the safest ledger stores poisoned data. Technology does not change people. If we cannot create honest, trained, independent data-collectors district to district, blockchain becomes a golden cage — beautiful, safe, empty inside.

The third danger is suspicion. Where I speak of transparency, I do not want it turned into a surveillance tool over innocent athletes. A teenage swimmer's personal data should never sit in a public ledger without consent. Transparency is for administrators, not for swimmers — and where that line falls, we have not yet decided.

The glass-pool trap: technology's new mirage

For four decades I have watched how every new opportunity opens another door of fantasy, and that fantasy does not fill the real pools. We dream of a franchise league, a television slot, a world-class facility. Yet swimming survives in our country in ponds, rivers, monsoon floods, and one old outdoor pool.

I do not want to confuse blockchain with that glass pool. It is not a new stadium; it is a ledger. A ledger's job is to keep accounts, and the capacity to keep accounts has long been absent in our country. That is its real value. If we pitch it wrongly, people will think technology is the solution and stop looking at the water.

Our first task is not technology but water — technology is the second step. To a nation that does not learn to swim, even the most perfect ledger is a closed book.

A feasible first step

I always say every demand needs a small, feasible first step — so it is not a fist shaken in the air but something tangible. That is my proposal for blockchain too.

Not the whole country at first. One district, one ghat, one season. Say every participant's name, ghat, coach and time in a long-distance race enters a simple, public digital ledger. On it the ghat witness, the boat judge and the coach each make a separate entry. If one entry does not match another, the mismatch surfaces publicly. That is blockchain's essence, at small scale.

This needs no vast budget. It needs a protocol, a few trained people, and a mobile application. No token, no speculation, no fraud. Only an account no single person can alter. If this small ledger succeeds, two more districts join next year. I know this is slow, but what I have learned on this beat is that slow does not mean dead — slow means durable.

The gallery: the last witness

For one month in 2026 Bangladesh watched swimming. Crowds filled Mirpur daily, the grandstand filled, and my microphone became a petition. Jewel Ahmed's name came up, a man who came close to thirty-five national golds yet still waited for reward money and a job. Listeners phoned, asked questions, and I read their questions instead of my own.

That month taught me that when a gallery fills, a pool becomes holy. A commentator's voice then works like a signature on a community's letter. But I also learned that this gallery comes for one month and goes quiet for the other eleven.

And here is my real link to blockchain. A gallery is a temporary witness — it comes, sees, and leaves. A ledger is a permanent witness — it does not come, but it stays. A witness in a grandstand loses their voice in the echo; a witness in a ledger is bound into every block.

I chose my beat because nobody wanted it. And this beat taught me where the real game lives — not on the field, often at the river's edge, on a wet ghat, beside an empty grandstand. Today I do not want to bring another gadget to those places; I want to bring a ledger — so that those who were lost at least keep their names.

Forward: the ledger and the water

I know blockchain will not save Bangladeshi swimming. It will not teach a child to float, build a pool, or pay a coach. But it can do one thing no one in this country ever has — hold the memory, and keep it open to everyone.

If a nation forgets its own record, it forgets its future too. From Mosharraf Hossain to Sagor–Himel — if those thirty-seven years had been written in a ledger, we would have no shame; we would have a foundation. On a foundation a house rises, a grandstand rises, a pool rises.

One more thing, my oldest belief. The river never forgets, but people do. The river remembers everything — every current, every drowning, every drowned child's name. We only need to learn the river's language. Blockchain is not that language; it is only a ledger in which that language can be written.

That evening at the Shitalakshya ghat I closed my notebook, but I did not close the truth. The truth is that our problem is not a lack of technology — it is a lack of the will to hold memory. Blockchain can awaken that will, if we do not turn it into another glass-pool dream.

And if we truly want it, the first step can be taken tonight — one name, one ghat, one time, one ledger. Time will do the rest. Time is like the river; it has no hurry, but it has no mercy either.
