Recovering the Lost Ledger: Blockchain for Preserving Bangladesh Cricket Data and Its Limits

Hook: A 2026 Spreadsheet, Now Unfindable

In 2026, I hand-coded every shot in Chattogram Abahani's 22 Bangladesh Premier League matches — 588 attempts, 197 on target. The resulting file was named bpl2017_v3_final.xlsx. Today, I cannot find that file on any of my three hard drives. A missing file is itself a data point — it is not zero, it is unknown. In my long career, I have seen countless such missing rows. When the BPL stopped in 2026, I re-coded data from 462 matches. That task took 14 months. The question has lingered: why is it so difficult for a cricket board to preserve its information? Why do outside rows, over counts, and margin figures disappear so easily? In 2026, as blockchain discussions flood into every match report, I am shifting the question: Can blockchain truly recover these lost rows? And if so, where are its practical limits?

Context: The Current State of Cricket Data Preservation in Bangladesh

Data from the Bangladesh Cricket Board (BCB) and each of its domestic tournaments is typically preserved across several layers: official website scorecards, editorial spreadsheets, and sometimes third-party databases. Each layer has its own version history, but those versions are usually not reconciled with one another. In 2026, the BCB upgraded its official scoring system, and during the data migration some ball-by-ball records for certain matches were lost — this was not officially disclosed, though various archive analysts have independently identified it.

From my own experience, while the BPL was suspended in 2026 and I was re-coding 462 matches, attendance figures were entirely absent for nearly 12% of matches. This was not zero — zero would mean no spectators. The issue was that no data had been entered. Any future analysis gets distorted by such absences. In an under-documented market like Bangladesh, the problem is even more acute.

The current proposal for blockchain technology is this: each match's data gets written to a decentralized ledger that no single party can alter unilaterally. Every data point gets a unique timestamp, and any change creates a new version without deleting the old one. On paper, this sounds excellent. In practice, though?

Core: How Blockchain Works and Its Application to Cricket Data

Technical Foundation

Blockchain is essentially a decentralized ledger composed of a chain of blocks linked by cryptographic hashes. Each block contains a timestamp, the hash of the previous block, and the transaction data. If someone alters an old block, the hashes of all subsequent blocks break, which the rest of the network detects immediately. This property is what makes blockchain attractive for cricket data preservation — because data cannot be edited, only new versions can be added.

Specific Applications for Cricket

1. Match Metadata Preservation: Date, venue, over count, result, and margin of each match get written into a block. When I published the chart showing Croatia's PPDA dropping to 6.9 at minute 60 during the 2026 England vs Croatia semifinal, I timestamped it so nobody could later claim I used hindsight. Blockchain automates this kind of timestamping.

2. Player Career Records: Runs, balls, fours, sixes, and official status of each batsman will reside in a permanent ledger. If a record is later corrected (for example, a delivery reclassified from wide to no-ball), a new entry is created while the old one remains. This solves one of the biggest problems in cricket archives — the history of corrections.

3. Transfer and Contract Data: One of my signature lines — "The ledger is patient; the transfer market is not." — is relevant here. Blockchain can bring transparency to player valuation and transfer fees, though in Bangladeshi domestic cricket this has not yet been felt.

Real-World Examples

Some initiatives have begun at the international level. In 2026, the International Cricket Council (ICC) started pilots on blockchain-based data verification with certain member boards, though Bangladesh is not yet on that list. Some Indian Premier League (IPL) franchises are storing player performance metrics on blockchain so that future disputes can be proven easily. These applications, however, remain at the pilot stage.

Special Challenges in the Bangladeshi Context

Data entry in Bangladeshi domestic cricket is often manual. A scorer writes details of 300+ deliveries by hand during a match. This data first goes into a spreadsheet, then to a website, then possibly to some archive. At every step there is a chance of error. Blockchain will only work if accuracy is ensured at the very first step — the original data entry. Garbage in, garbage out — blockchain is no exception to this rule.

Contrarian Angle: Correlation, Not Curation

Blockchain Is Not a Solution, It Is a Tool

In my long career I have learned one thing: technology is not a solution to a problem, it is a tool. Blockchain can prevent data alteration, but it cannot improve data collection quality. If a scorer makes a mistake and writes the wrong ball count, that error becomes permanent on the blockchain — it cannot be corrected, only a new entry can be added. This is sometimes a problem, sometimes a feature.

Cost and Limits of Knowledge

Operating a blockchain system requires significant computing power and bandwidth. In a country like Bangladesh where cricket board IT budgets are limited, implementing a full blockchain system would be difficult. My 2026 spreadsheet was not lost due to lack of technology — it was lost due to organizational neglect. Blockchain cannot prevent such neglect.

Correlation ≠ Curation

Many people view adopting blockchain as correlated with data preservation, but it is not curation. Blockchain preserves data, but the responsibility of creating, editing, and interpreting that data still rests with humans. A blockchain may hold well-preserved dates and over counts, but if nobody performs correct analysis with that data, it has no value.

The Role of Bangladeshi Scorers and Archivists

I was born in Australia but work in Bangladesh, yet the focus of my work has always been recognizing the contributions of Bangladeshi scorers, statisticians, and historians. If blockchain technology succeeds in Bangladesh, it will be because of these people, not because of the technology. Every line written by their hands, every ball of every match — these are the real assets.

Takeaway: Signals for the Next Round

If I worked in the data preservation department of the Bangladesh Cricket Board, before adopting blockchain I would do three things: first, conduct a complete audit of existing data (which matches have data, which do not); second, ensure data entry quality; third, then migrate to blockchain. Blockchain is a powerful tool for preserving Bangladeshi cricket data, but it is not magic. Over the next five years, I would like to see whether the BCB launches any pilot project, and if so, which match it starts with. In my estimation, the 2027 BPL could be a good testing ground — 22 matches, familiar scorers, and a familiar data set. At that point I would look back — which rows existed before, which exist now, and which are still lost. The ledger is patient; blockchain can be too, if held in the right hands.
