From Timing Chips to Blockchain: A New Horizon for Verifying Athletic Timings

In October 2026, at the Bangabandhu National Stadium in Dhaka, the men's 100m final of the 40th National Athletics Championships had just ended. I was then working for the first time at the digital sports desk of a Dhaka daily. The electronic timing monitor flashed the winner's name and time. But when I turned the old pages of the meet programme, I saw that the men's 100m record predated the electronic timing era. Comparing a time with that record means erasing the difference between hand-timing and electronic timing. That evening I understood that the history of athletics is not just about running; it is also about verifying time.|Since then, I have developed a habit. Whenever I write about a decline or rise, I mention the timing method. Because in South Asian athletics, the record book often relies on memory, not the clock. Between 2026 and 2026, Bangladeshi sprinters won South Asian titles. Most of those times were hand-timed—two or three timekeepers, no separate reaction time, and no photo finish, just an approximation by eye at the finish line. Today's electronic timing, where a transponder chip is tied to the shoe, takes the signal directly from the athlete's body and gives split times for each sector. Comparing the results of these two methods in the same seat is an injustice to history.|But sadly, the Bangladesh Athletics Federation and most media still do not accept that difference. Over the past few decades, national championship results have been preserved in paper files, electronic spreadsheets, and sometimes only in media reports. If time, reaction, and wind speed are in handwritten notebooks, it is nearly impossible to verify them later. This lack of verification weakens history, and that weakness sometimes allows records to be falsely claimed or legitimate records to be denied.|This is where blockchain technology becomes relevant. Using smart contracts, World Athletics could define the criteria for time verification. Before each competition, an immutable record would be created in the system. Data directly from the timing device—reaction time, wind speed, stadium temperature—would all be hashed into a block simultaneously. If someone later tries to alter the result, the hash changes, and the blockchain catches it. Implementation is not simple.|First, who holds the blockchain key? The federation or an independent Olympic committee? Second, who pays for electronic timing chips at every event? Third, if NFTs are used in athletics, will athletes own every second? One controversial proposal could be that the NFT of each record belongs to the athlete, granting independence from clubs or sponsors.|Now the question is, what lies beyond digital verification? This technology does not cure the old disease of athletics—the lack of a pipeline. There are no synthetic tracks in Rangpur, Rajshahi, Barishal, or Sylhet. The national championships are mainly contested by army, navy, and air force athletes and BKSP trainees. School and college athletics is almost nonexistent. Blockchain will preserve data like a collector's trophy, but without new tracks, where will new talent come from?|There is another danger—centralization of timing data. If data sits on Ethereum or Binance Smart Chain, servers can fail anytime, or rising network fees can make it costly for small meets. If we create a new central body in the name of decentralization, the old problem returns.|Personally, I think blockchain is not a solution to athletics' problems but a tool. In a verification crisis, it can act like an honest clock. But where there is no track, no coach, no scholarship, just putting a blockchain chip will not stop the race. The truth of a record depends on the integrity of the system behind it.|Time verification in sports is now a global issue. If World Athletics introduces blockchain-based time registration before the 2028 Los Angeles Olympics, a new door will open for small countries—their records will gain international recognition faster. But if athletes from countries without synthetic tracks cannot walk through that door, the technology will become just another pillar of wealthy sports systems.|Blockchain is not the last word. The last word is that the more transparent the clock used to measure a race, the more believable the story of that race. For the archive, blockchain is a small mirror, but the stadium missing behind the mirror must be rebuilt with bricks and sand.
