Blockchain Enters Cricket's Umpiring Ledger: A Decision That Cannot Be Reversed

The memory of that 2026 night inside the Mirpur press box is still fresh. A disputed goal in the 78th minute of a Dhaka Premier League match had triggered an offside debate. I was explaining the decision under Law 11 with a 14-frame sequence. A journalist beside me asked, "Why are you so sure? Does every camera angle show the same thing?" Today that question does not have to be answered only through frames. If the complete history of a replay is written into an immutable ledger, the argument ends where it should: at the evidence. Cricket has changed many times through technology. Hawk-Eye, Snickometer, UltraEdge—each tool exists to reach a decision. But the path that led to a decision is almost never preserved. If the review log, camera angles and timestamps are stored in a blockchain, accountability enters the game in a new way. A distributed ledger is perhaps the most important phrase in cricket administration now. A blockchain records information in blocks that are sealed by the hash of the previous block. No single authority can alter or erase it. That quality matches cricket's need. Umpires' decisions, captains' reviews, ball positions, digital tickets—all of it can be placed on a ledger where nobody can secretly interfere. When I wrote about 29 reviews during the 2026 World Cup, I thought it would be valuable if those reviews were a permanent public archive. Seven years later, that wish has become a technological reality. The most visible form of blockchain in cricket is the fan token and digital collectibles. The England and Wales Cricket Board, Cricket Australia, and the ICC's official digital platform have all invested in NFTs or fan tokens. A fan token is a digital asset; after buying one, a fan can vote on small club decisions. Digital collectibles of Virat Kohli, Babar Azam and Tamim Iqbal have appeared in the market. Ticketing also stands to gain: if one seat is tied to one verified digital token, black-market resale becomes far harder. For me, the most important use is DRS. The third umpire watches replays, but we only see the angles chosen by the broadcast. If a cameraman does not send a feed, that angle never appears on screen. Yet that invisible angle can decide a match. If every review is sealed into a block with raw footage from all cameras, a dispute becomes a question, not an accusation. I have watched cricket for twenty-five years. Experience has taught me that the biggest error is not always in the decision; it is in the path to the decision. In 2026, with empty stadiums, broadcast microphones picked up umpires' conversations. That silence showed how much crowd noise used to hide. Blockchain can remove that cover. From the umpire's microphone to every click in the review room, a ledger can explain why a decision took time and which frame changed the outcome. I maintain my own database: nine years of match and review data. Every match is a row, every review is a column. This habit is my trade. I can say with confidence that blockchain can turn a private database into a public ledger. A captain who lost seventeen of twenty-nine reviews will be judged by data, not emotion. An umpire who changed his mind three times in one review will be answerable to every cricket board. I look at Bangladesh's domestic cricket as the laboratory. Patterns appear first in Mirpur and in the National Cricket League before they arrive in Tests. Blockchain also deserves to be tested in domestic cricket first. If a Dhaka Premier League match puts its review log and official decisions on a public ledger, fans will see that the system is not complicating the game; it is keeping the game's record. Bangladesh's internet ecosystem is ready for such a proof-based system. Smart contracts are another layer. A player's contract can release payment only after fitness checks, doping samples and matches played are verified automatically. This removes the need for personal negotiation at each step. Board bias, manager pressure and secret transactions related to match-fixing become far harder to hide. Of course, critics will say a human still makes decisions on the field. That is true. Blockchain will not call a ball out or decide a catch. The
