Procurement corruption–including things like bid rigging, shadow vendors, and the steering of public contracts to politically connected firms—is an enormous worldwide problem, costing taxpayers up to $2 trillion annually. New technologies, though certainly no panacea, may offer new techniques for combating this sort of corruption. One such technology is blockchain.
Blockchain, most famous as the foundational technology for cryptocurrencies such as Bitcoin, is a “distributed ledger technology” (DLT)—a tamper-proof record of activities that are time-stamped and verified by a distributed network of computers. DLT creates a trail of information which allows for the full traceability of every transaction and stores a chronological list of transactions in an encrypted ledger. Transactions are bundled into a secure and identifiable block and then added to a corresponding chain. The blockchain is maintained and verified by the distributed crowd, eliminating the need for hierarchy and any centralized authority or middleman. And while blockchain is best known for its role in making cryptocurrencies feasible, it also has a range of other applications, including anticorruption applications. For example, Tanzania has utilized the technology to weed out “ghost workers” from the public sector, ending the monthly outflow of 430 billion Tanzanian shillings (approximately US$195.4 million) in salaries to fake employees who exist only on paper. Nigeria’s customs service has also used blockchain technology to store information on financial transactions and share these transactions across multiple computer networks.
Blockchain technology could also be used to combat common forms of procurement corruption, particularly those that involve after-the-fact tampering with submitted bids and supporting documentation. Such a system would work as follows: Continue reading
