Blockchain Technology and Swimming: A New Horizon in Delta Waters

Swimming is the lifeline of our delta, yet in administrative ledgers it remains a neglected sport. As blockchain technology opens new possibilities in sports management, I recall that day in 2026 at the Mirpur outdoor pool when I first understood that swimming's true story was never written in medal counts. I do not want to confuse blockchain with cryptocurrency; it is a transparent ledger where every swimmer's district, river, coach, and personal best can be immutably recorded.

When I covered the nearly ten-kilometer long-distance race on the Shitalakshya in 2026, there was no grandstand, no scoreboard, no touchpad. There was only a crowd on the banks and a line of heads in the river. That experience taught me that Bangladeshi swimming truly lives in river water, not pool chlorine. If blockchain can preserve the accounts of every ghat, every swimmer, and every drowning, it will be a revolutionary change for our sports administration.

The first major crisis in Bangladeshi swimming is the lack of transparency. Navy dominance, Army second, BKSP third—this medal table is actually a diagnosis. I have said many times that after four decades of universality places, there is not a single merit-based qualifier. The root cause is that our swimmers' performance data is not stored anywhere. Even if a rural swimmer reaches 24 seconds in the 50m freestyle, there is no system to record it. Blockchain technology can solve this problem.

The core advantage of blockchain is immutability and transparency. If a smartphone records swimmers' times at every district ghat and stores them on blockchain, no one can erase or falsify that data. From this data, we can create a national ranking that will identify talent across the country, not just in the Navy.

In 2026, I was commentating at the Mirpur pool during the 11th SA Games. Mahfizur Rahman Sagor, then a teenager, won silver and bronze, and a gallery that had been empty for a decade suddenly filled. In that moment, I understood that a crowd can make a pool holy. But that crowd lasted only one month. If swimming is broadcast year-round on a blockchain-based platform, that crowd can become permanent.

I cannot forget Jewel Ahmed. After winning 35 national golds, he was still waiting for reward money and a job. In 2026, I turned my microphone into a petition. Listeners would call and ask why this swimmer had not yet received his due. I would read their questions on air. If blockchain had recorded those promised funds and rewards, perhaps Jewel Ahmed would not have had to wait year after year.

I have a notebook titled 'Owed to Whom.' In it, every swimmer's name, date, and promised money are recorded. This notebook taught me that without accounts, an athlete's sweat becomes worthless. Blockchain can be the digital version of that notebook, which no one can erase.

But I want to be cautious. Blockchain is not magic. In rural Bangladesh where there is no internet connection, implementing a blockchain-based system is difficult. So my proposal is to first launch a simple digital registry at the district level, which will later transition to blockchain. At each ghat, a coach will record swimmers' times and send them to a central server.

I do not want blockchain to remain a game only for the urban elite. We must think of the rural girl in Barishal who fights both the river and social barriers. If we record her times and progress on blockchain, she will get the opportunity to compete at the national level.

Swimming is not just a sport; it is survival infrastructure. In a delta country where nearly 40 children drown every day, teaching swimming is a public health program. If blockchain records drowning deaths in every district, we can see which districts have the most child drownings and launch swimming programs there.

In 2026, when I first commentated at the Mirpur pool, I mistakenly announced a Bangladeshi breaststroker as third when he had finished fourth. That mistake taught me never to call a swimmer's position until the touchpad confirms it. I still carry that lesson today. If blockchain records every touchpad result, journalists will not report incorrectly.

When I made my international commentary debut in 2026 during the Bangladesh women's ODI series against India, I understood how much technology can advance sports. But technology only works when it is accessible to all. If blockchain is reserved only for elite clubs and wealthy swimmers, it will not solve our problems.

My suggestion is that the Bangladesh Swimming Federation launch a pilot project. First, three districts—Barishal, Khulna, and Sylhet—should be selected. There, times should be recorded via a mobile app at every ghat and stored on blockchain. After one year, results should be reviewed. If successful, it should be expanded nationwide.

The biggest challenge of blockchain is the digital divide. In our country, where many people still do not know how to use smartphones, implementing blockchain will not be easy. So my proposal is to first create a simple digital registry that can be updated via SMS and voice calls. Later, when internet connectivity increases, it can transition to blockchain.

I do not want blockchain to remain merely an exhibition of urban modernity. Rather, it should be a ladder for rural swimmers. For every name written in my notebook, a digital identity will be created. Their times, their rivers, their coaches—everything will be preserved.

I believe blockchain technology will not only give Bangladeshi swimming administrative transparency but will also create a new kind of sports culture. Where every ghat becomes a mini stadium, every swimmer a data point, and every record immortal.

The final word is that swimming is in our blood. Padma, Meghna, Shitalakshya—these rivers taught us how to fight with water. Blockchain will keep the accounts of that fight. The question is, are we ready to keep those accounts? Or will we again lose a generation to the water without keeping any ledger at all?
