Cricket's Invisible Ledger: Ball-by-Ball Data Integrity and Blockchain's Unsettled Account

Close to one in the morning last Friday, I opened a ball-by-ball feed for a match in progress. The ledger came back empty. No headline, no source, no information points, no player names — just a few blank cells and a note beside them reading "insufficient information, cannot assess." In fifty-three years I have reconciled many faulty ledgers, but a ledger that returns entirely blank is a different experience. This is not an error in the numbers; it is the absence of numbers. In cricket, missing data means far more than one report stalling — it means fantasy-league scores, broadcast graphics, the inputs to DRS, and market odds all going blind at once. Sitting in front of that empty ledger, I thought: we generate so many layers of data, yet we have no permanent system for proving where it came from. This piece is about that unsettled account. Cricket today is not merely a game on twenty-two yards; it is a vast data industry. Every ball, every run, every dot ball, every over's speed — all of it is recorded, printed on broadcasts, loaded into fantasy apps, fed into markets. At the head of this supply chain sits a scorer, an official feed, a few cameras, and some sensors. The curious part is that if a number changes somewhere along the chain, nothing catches it. Who changed a run, when, and why — there is no permanent receipt for any of it. I have seen, many times, two different statistics for the same match on two feeds. On one, a batter's strike rate reads 142; on the other, 138. Which is right? Nobody knows, because nobody is held accountable. I understood this problem anew at the 2026 World Cup in Russia. After England lost to Croatia, new media wrote that England had controlled the match. I opened the data: Croatia's xG was 2.1, England's 1.1; Croatia's PPDA was 12.4, England's 8.7. The numbers said otherwise. But the real question sits right there — which ledger am I trusting? Who is the source of the feed these numbers came from? Croatia ran 14.3 kilometres, yet the xG correction rewrote the story — but where is the receipt for those 14.3 kilometres? Had every metre of Luka Modric's running been written into a verifiable ledger, the argument would have settled at the level of information, not emotion. Earlier still, in 2026, in a Delhi football press room, I built a validity index for 47 transfer deals — using minutes, wages, and age curves. Only 12 deals passed the test. Dimitar Berbatov was 36 then, and new media was swept up in enthusiasm over him. I reconciled the 47-deal ledger and found the maths did not hold. That day I learned: I will not write a story until the ledger reconciles. Cricket's data chain today needs exactly that discipline. This is where blockchain becomes relevant. Blockchain is fundamentally a ledger — but a ledger that, once written, cannot be erased. Each ball is a block. Each block carries the hash of the previous block. If anyone tries to alter a number in the middle, the whole chain breaks, and it is caught instantly. What does this mean for cricket? Suppose every ball of an over, as it is scored, is written into an immutable ledger, time-stamped, with its source identified. Then no one can later claim that a run never happened. Behind every number there would be proof — who wrote it, when they wrote it, which camera or sensor it came from. This technology can apply directly in a few specific corners of cricket. Consider the auction. IPL and other franchise-league auctions move enormous sums, yet who received how much, and when, is not transparent to anyone outside. A smart contract could place auction escrow, player payments, and image-rights accounting into a permanent ledger. Consider fantasy and market data too. Fantasy-league point disputes arise almost every week. If ball-by-ball data came from a verifiable ledger, the disputes would shrink. And consider the audit of DRS and match-official decisions. If what a ball-tracking feed said were preserved immutably, later verification would be simple. In a heated Bangladesh-India series, much of the storm over a controversial LBW decision — whether the player is Shakib Al Hasan or Mushfiqur Rahim — could be calmed if the decision's input data were preserved with proof. But here is my caution, and this part matters most. Blockchain gives immutability, not accuracy. There is an old line in computer science: garbage in, garbage out. If a scorer mistakenly logs a wicket, blockchain will preserve that error forever — only now it is immutably wrong. A wrong number is hard to erase, and a verified immovable error is sometimes more dangerous than an immovable truth, because it claims to be proven. Building the 47-deal index taught me this: a ledger alone does not make the maths hold; the ledger's rules and the honesty of its source must hold too. Second, the governance question is bigger than blockchain itself. If a board runs its own private chain, that is not decentralisation; it is simply a new centre. Who verifies? Who runs the nodes? Who owns the data — the board, the broadcaster, or the betting company? Bringing blockchain into cricket without answering these questions will not increase transparency; it will consolidate the old power structure more tightly. Writing a block every second into live ball-by-ball data is also technically expensive, and one second of delay means a blank screen on a broadcast graphic. So next season I want to watch for one signal: not full decentralisation, but federated verification. A few independent parties — the board, a broadcaster, a neutral audit body — guarding one ledger together, where no single party can unilaterally change anything. If cricket walks this path, then an old auditor like me will not sit in front of an empty ledger next match. She will reconcile the book and say: this number is true, and here is its receipt.
