Road tolls are more secure thanks to blockchain

Technology firm Indra has added a new feature to its road-toll payment system, which is capable of recording transactions on a distributed ledger (DLT). Improved transparency and traceability of toll transactions will result from the CRITICAL-CHAINS project, which created this capability. On a Mexican highway, the pilot solution is being tried.

Toll-fee fraud and hacking have an impact on both road owners and users. Emails alleging that receivers haven't paid for utilizing a toll road are the most common form of scam. But road owners face a wider range of scams, including the use of counterfeit gasoline and credit cards to pay tolls, hacked toll systems, and the inability of concessionaires to record all toll payments. This problem can be solved by the CRITICAL-CHAINS partner.

The Monterrey-Saltillo motorway in Mexico will be used as a testbed for Indra's autonomous driving technology. The implementation of blockchain does not change how road users interact with the system; rather, it raises the possibility of data discrepancies.

To boost trade, Africa is simplifying international payment systems

It's hard to transfer money between African countries. The Ghanaian king settled a bill with a Nigerian attorney. His experience highlights a systemic problem impeding Africa's economic growth: high transaction costs and inconvenience. 15% of all imports and exports occur between 55 African countries. 60% of Asian trade is within Asia. 70% in EU.

Multiple countries' initiatives in the central bank digital currency arena, most notably China's, have heightened debate about how aggressively the Fed should act. The Federal Reserve is pushing ahead with its plans to create its own digital currency, stating that a study paper will be released this summer that will go deeper into the topic.

In the statement, The proper operation of our economy requires that consumers have faith and confidence not only in the dollar, but also in the payment networks, banks, and other payment service providers that allow money to flow on a regular basi...

How will Blockchain boost trade in Africa?

Despite a regional economic slowdown in 2020, over a dozen African countries grew last year. Complicated trade rules and lengthy border processes stifle African economies. These long-standing issues need creative solutions. Blockchain is becoming more practical and scalable in developing markets. It has just opened a regulatory "sandbox" for innovative blockchain-based goods in Ghana. Standard Bank has joined Marco Polo, a trade financing network. Here are four ways blockchain may help African trade: 1. Customs The AU-EU trade deal is still in its infancy. Traditional customs bureaucracy prevents SMEs from joining global trade networks. This procedure can be automated and simplified, saving time and money. 2. Traceability Tracking cross-border goods correctly is critical for standard and certification verification. Already, blockchain is allowing ethical supply chains for a variety of African goods. Its open-source but secure design makes certificates easy to issue and verify...
