The Ledger No One Can Tear: Blockchain and the New Question of Sports Records

1. The National Stadium in Dhaka, the SAF Games. I was twenty-two, six months past a journalism degree, filing for BSS and Dainik Bangla. Around 140 journalists held press accreditation; three of us were women. In nine days I filed nine dispatches, six on athletics. Every result came on a carbon-copy sheet, hand-timed — there was no electronic timing anywhere in the stadium. That week I began a habit: copying every mark, every name, every results sheet by hand and filing it by year. The reason was simple. The sheet was the only document that never lied. The first results sheet is never just paper; it is a doorway — through it walk who ran, who was dropped, and who kept the account.

Forty years later, that sheet has a digital descendant. Its name is blockchain. The question is no longer where the sheet is kept. The question is whether a sheet no one can ever tear or erase automatically becomes true.

What the ledger actually is needs clearing up first. Put simply, a blockchain is a ledger, but not an ordinary one. In an ordinary ledger one person writes, and that same person can strike a line out and write it again without leaving a trace. In a blockchain every entry is a block; each block carries a digital fingerprint of the block before it, and exact copies of the ledger are spread across countless computers. To change one entry you must change not one copy but all of them at once — practically impossible. So the ledger becomes immutable.

Sport has already begun letting this ledger in, through several doors. Big European football clubs have launched fan tokens, letting supporters vote on minor club decisions. A few clubs have tested blockchain-based tickets to stop forgeries. Proposals have appeared for tracking athlete contracts, sponsorships and image rights. And the most important door, the one I care about most: chain-of-custody for doping samples — an unalterable record of which sample went into whose hands, and when.

A small but vital clarification belongs here. There is much enthusiasm about blockchain and sport, but enthusiasm and evidence are two different things. What does a fan token actually do? A supporter buys a digital token and in return can vote on certain club decisions — which song plays, which shirt design appears. That is entertainment, not governance. The ledger here is an audience magnet, not an accountability document.

Another door is equipment. In modern athletics, carbon plates in shoes and new fabrics change performance. Which athlete used which equipment, whether it was approved, when it changed — that record matters for the rules. A ledger could make it flawless. But remember: shoe technology both sets records and throws the value of records into question. The ledger records the machine; it does not judge whether the machine was fair.

And this is where an old habit of mine returns. I have spent a lifetime learning that a ledger and the truth are two different things. A ledger writes down only what it is told. Blockchain solves the problem of editing; it does not put the duty of verifying an entry on anyone's shoulders.

Think about it. Had electronic timing existed in 2026, someone would still have had to decide who pressed the trigger, who was in which lane, which photo-finish frame came first. Electronic timing stops a typing error; it does not stop a wrong judgement. The same holds for blockchain. Immutability and reliability are not the same thing — the first is given by technology, the second by institutions.

And here is the real fracture. Since 2026 I have stopped writing gold-medal stories and started writing supply stories — who feeds the pipeline, who pays, who leaves. The disease the sports bodies suffer from is not something blockchain treats. A federation that cannot maintain a synthetic track — how will it run a node?

In 2026 in Islamabad, Bangladesh won zero athletics medals. In 2026 in Colombo, Mahfuzur Rahman Mithu won the 110m hurdles — to this day the last. I was forty-three then, done waiting for press releases, and I built a spreadsheet: every Bangladeshi SAF Games athletics medal since 2026, four sprint golds and one hurdles gold, with the empty years deliberately left blank. The blank cells were the real information. A blockchain ledger could have made those blank cells permanently immutable — but it could never have said why the cells were blank.

One thing I say from years of watching sport from the tribune. Sport's problem is almost never a lack of information; it is the weight of information. Who is writing it, in whose interest — that is the real question. Blockchain does not remove that weight. It may add to it. An immutable entry looks far more credible, even when it is wrong.

Consider doping. From sample collection to lab, from lab to result, blockchain can keep the chain of custody flawless. No one can go back and change a date. That is undeniably progress. But the question remains: if the sample was collected badly, if the lab was not properly calibrated, then a mistake is recorded immutably. In the hand-timing era a wrong result could at least be corrected, a mistake admitted. On a blockchain, admitting a mistake means rewriting history — which the technology refuses to allow.

That is why blockchain is not a solution for sport; it is a test. The technology asks one question: who gets to write? The institution answers it. And if the answer is “the same people who always wrote,” then the technology changed and the power did not.

Take the youth pipeline. Big clubs now run satellite systems, signing promising players from small leagues early but never playing them in the first team. Technology could make this transparent — who is on loan where, who will return, who never will. Blockchain could record it immutably. But who gets the right to see that data? Usually the club, the agent and the sponsor — not the player. A transparent ledger is not transparent power.

Now the other side, the one blockchain enthusiasts mention less. Suppose sports bodies really did put every result on a blockchain. Would corruption fall? I doubt it. Corruption does not happen inside the ledger; it happens in the moment just before the entry is made. If a board that decides who runs and who is dropped makes a deliberately biased decision, blockchain will only preserve it more securely. In the mixed zone, where the medal stands with the microphone and the only woman, the question was never the ledger — it was who stands at the ledger's door.

And one more thing, about which I hold an age-earned hesitation. Immutability carries a danger that is rarely discussed. What if an athlete wants false information erased? If an entry is made by mistake or unjustly, it is carved in for good. The right to be forgotten and the technology of never forgetting cannot coexist. In sport's history many athletes have stood unjustly under a cloud of suspicion; for them a ledger that cannot be erased is not protection but punishment.

So I see blockchain the way I see the phrase “load management” — a useful idea, but often a mask for a commercial calendar. The word blockchain now hangs like a billboard, and sport has an old habit with billboards: paying to make imported stars shine while never looking at the home pipeline. Technology does not change that habit.

In 2026 Dhaka hosted the South Asian Games. Host nation, home crowd, and still no athletics gold. Standing on the infield that year, I understood the real story was not the medal table but infrastructure. There was exactly one track worth the name, at the Bangabandhu National Stadium, while the eight divisional towns ran on mud and grass. That was the year I left the daily desk for long-form documentary research, where a story cannot be spiked by a phone call. That experience taught me that technology brings improvement at the last layer; it does not solve the foundational problem.

I do not see blockchain as sport's enemy. Quite the opposite — someone like me, who has trusted carbon-copy sheets and handwritten ledgers all her life, knows what a gift an immutable digital ledger can be. But the gift works only when the same rigour is applied to who stands at the ledger's door. The question is no longer whether blockchain arrives. The question is whose hand holds the pen. A stopwatch can start a career, but a ledger decides what it meant.
