Can cryptocurrencies and blockchain help fight corruption?

Blockchain and cryptocurrencies similar to Bitcoin could transform the way we make payments and do business. They also hold great promise as a method of fighting corruption.

Technological advances have made it possible to dramatically increase the accountability and transparency of public financing to reduce corruption. For example, if a government decides to construct a road, it can now track how each dollar is being spent, identify all the users of the funds, and ensure that only those authorized to spend money do so on originally intended expenses within the permitted time. Fraud and corruption investigations that now take on average 15 months could be performed at the touch of a button and at a fraction of the cost. More importantly, this type of financial tracking would be a deterrent for bribes in the public sector, which amount to between $1.5 trillion and $2 trillion annually, roughly 2 percent of global GDP. This in turn would increase development impact. All it would take is adopting a cryptocurrency and using blockchain software.

The adoption of cryptocurrency—a digital currency that employs cryptography to ensure that transactions are secure—as a mode of payment for a project allows the identification of each user of the money, unlike with traditional modes of payment like notes and coins. Though most popular cryptocurrencies, like bitcoin, are anonymous and only use a key to identify a user, it is possible to include personal information, like the ID number, and make the cryptocurrency non-anonymous. The use of cryptocurrency also allows for instantaneous transactions and borderless transfer-of-ownership (“money with wings”), which reduces transaction time and cost, since financial intermediaries are not needed.

A government or development institution could use an existing non-anonymous cryptocurrency or develop its own and give it a name, such as “cleancoin” for example. The value of the cryptocurrency can be determined by the market or preferably be pegged to a physical currency to reduce volatility (bitcoin for instance has shown very high volatility since its inception).

The adoption of blockchain helps track the use of the cryptocurrency. The blockchain is a continuously growing list of transactions (blocks) made using cryptocurrency that are recorded chronologically. The blockchain is managed by a peer-to-peer network (miners) collectively adhering to a protocol for validating new blocks. Once the transaction data in a block is recorded, it cannot be altered retroactively as it would require altering all the subsequent blocks. As the data is stored in many computers, there is little risk of data loss, and since it is encrypted, the confidentiality of data is maintained. Because the blockchain is a public ledger of all cryptocurrency transactions, it is searchable and can be used to track all transactions.

The lack of anonymity and the tight traceability makes corruption more difficult, unlike with traditional money. Two additional features will help fight fraud and corruption effectively. First, the blocks should contain additional data that typically stored so that there is sufficient information for the purposes of fraud and corruption enforcement. For instance, the block can store the nature of the expense and the project and activity linked to the funds. Second, the verification of a block should include checking that the additional data satisfies the smart contract. A smart contract contains logical clauses programmed in the code that triggers processes according to the terms of a contract. These terms could define the conditions to be met to release funds, dates from which they can be made available, and so on. The satisfaction of the contract helps prevent improper expenses.

These four features can be incorporated using Ethereum technology. Ethereum is an open source software platform based on the use of blockchain that allows for the creation of new cryptocurrency types that are not anonymous and permits the inclusion of additional information in the blocks and the use of smart contract features. With the platform set up, the government or development institution could simply allocate cryptocurrency to the activities as budgeted. Those persons or firms assigned to the activities would be allowed to take the cryptocurrency and spend it in goods and services, with verification being performed in the Ethereum platform according to the set protocol and contract. The verification would be performed by insider or external miners who would be rewarded with a share of the cryptocurrency or through transaction fees.

Access to the cryptocurrency would be provided using software wallets (which do not require having a bank account, an advantage in developing countries with low financial access). The final holders of cryptocurrency can convert it into fiat currency at an exchange market—which could be a primary exchange market run by the development institution or government or a secondary exchange market (Figure 1). The end goal is to move the transition from crypto to fiat currency as close as possible to the end beneficiary of money. This will give maximum control over the way money is spent and reduce opportunities for misuse.

Cryptocurrency and blockchain could help prevent fraud and corruption, and reduce the costs of enforcement, thanks to easily accessible information and faster crosschecks, and help supervise implementation and monitor efficiency and effectiveness of spending, increasing development impact.

Excellent introduction to not only reducing corruption, but also to the widespread exploitation of the poorest of the poor in developing country cities. Block chain could, for the reasons stated in this piece also smoothen the interface between the formal and informal sectors, and ensure that participants in the latter group get their fair share of incomes. Imagine, for example, a city-wide program launched to utilize anaerobic digestion processes to promote circular economy ideas - such as converting Greenhouse Gases into renewable energy from a city's sludge, fecal sludge and organic wastes. Currently, a significant institutional challenge is to figure out how to organize the separation, collection and conveyance of household organic wastes (undertaken by thousands of waste pickers, fecal sludge emptiers and low wage municipal conservancy workers), so that they have the incentives to participate in a sustainable manner. Using block chain technology the waste treatment operator could contract these waste pickers through these distributed ledgers to seamlessly pay for organic wastes and fecal sludge delivered, which meet the moisture content requirements. The more the separated wastes and fecal sludge delivered, the higher the remuneration, without "waste mafias" extorting rents from these poorest of the urban poor!

The objective is to come out with collective measures to highlight corruption trends in both public and private Institution around the world It will need to build up a platform Intends to serve two mutually reinforcing objectives in particular to provide a collective space for all to engage in the definition of good governance and human rights agenda in the world Integration process catalyze and deepen the good human rights policy discussions and a space for dialogue critical and fundamental to regional Integration process and it will need a survey to gear- up towards getting people's perception on bribery while seeking service delivery in both public and private ,there is great alliance of evil people supports bribe like president museveni is the chairman of the board to curry on with corruption Including other leaders,I have been looking for a recommendation but they asked for money but they never recommend me to the university as a result to block the opportunity may the world bank help me to support this chance and curbing corruption will Improve lives and these are the major roots .
Breakdown in the rule of law
lack of clear understanding of existing code of conduct
poor procurement systems
Inadequate legal machinery
lack of or unclear Inter-Institutional linkages
Inadequate systems , logistics and capacities in public offices
Greed and many others
