Want fewer corruption trials? Make govt records tamper-proof

A golf club security manager's admission in Malaysia's corruption trial exposed a vulnerability that plagues every courtroom, tender and audit in the country. S Saravanan, the group security head of Tropicana Golf & Country Resort, testified in Muhyiddin Yassin's trial that he could not verify the accuracy of computer records that showed the former prime minister's golfing arrangement with businessman Azman Yusoff on July 19, 2020.

Defense counsel later pointed out that these records could be modified, which left Saravanan uncertain about this possibility. This situation is not exclusive to one trial; in August, former Prime Ministers Najib Razak, Muhyiddin Yassin and Ismail Sabri Yaakob appeared in Kuala Lumpur Court Complex for separate proceedings. Najib faced a massive US$5.64 billion civil suit from 1MDB, Muhyiddin's corruption trial continued, and Ismail Sabri pleaded not guilty to failing to declare assets.

Almost every record the Malaysian state relies on, from procurement evaluations to departmental expenditure files, is stored in common databases that can be altered by anyone with the administrator password. Blockchain technology offers a solution by creating a tamper-proof record log. When a record is created, such as a bid submission or award signing, the system generates a cryptographic hash, a unique digital fingerprint, and publishes it to a blockchain.

If anyone attempts to alter the record, the fingerprint will no longer match, instantly detecting any tampering. This technology cannot verify the record's truth at the time of creation or stop illicit cash transactions, but it eliminates backdating, quiet edits, and vanishing files. Three steps could implement this solution: first, mandate procurement to require ePerolehan to hash every tender milestone and award decision to the national blockchain.

Second, grant the National Audit Department read-only access to anchored expenditure logs, turning audits into continuous monitoring. Third, update the Evidence Act 1950 to recognize cryptographic proof of record integrity. Implementing these changes would harden Malaysia's system against corruption, ensuring that the guilty are cornered and the innocent are protected.
