How Blockchain can help improve IAM?

The digitization of society is driving the digitalization of identity. Paper-based forms of identity are becoming increasingly unfit for the digital world. It is unclear, though, how emerging technologies will reshape identity in the future. In organizational settings, identity and access management (IAM) technologies have a large role in identifying, authenticating and authorizing who accesses services or systems. Identity attributes are the labels attached to identities: employment, nationality, relationship to a service provider, access to government entitlements.

Distributed ledger technology (DLT) is among several emerging technologies that present potential models for IAM. At its core, it enables transactions, authentications and interactions to be logged and verified by a network rather than a single central authority. DLT is best understood as an umbrella term that encompasses various distributed designs for data security.

Here are 10 ways blockchain improves IAM:

1. Multiparty verification

2. Verifiable credentials

3. Distributing attributes

4. Accessing attributes

5. Attribute provenance

6. Data minimization

7. Audit trails

8. Compliance verification

9. Self-sovereign identity (SSI)

10. Decentralized identifiers (DIDs)

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. The difficulty of international payments hinders African trade. There are also high tariffs, long border procedures, and congested roads. Proponents of AfCFTA say easing trade restrictions will boost trade, FDI, and economic growth. 50 million people will be lifted out of extreme poverty by 2035 due to the accord's positive impact on real income, which is projected to rise 9.1%. Another issue: In Africa, currency values fluctuate. From July 2021 to 2022, Ghana's currency fell from 6 to 8. Volatile currencies make financial transactions more costly and risky. To overcome these problems, PAPSS facilitates financial transactions ...

Eight countries, including China, banned to own or use cryptocurrency of any kind

There are dozens of governments and jurisdictions throughout the world that have either banned or severely regulated digital money in recent years, including China. Egypt, Iraq, Qatar, Oman, Morocco, Algeria, Tunisia, Bangladesh, and China are among the countries that have banned the use of cryptocurrency. Algeria, Bahrain, Bangladesh, and Bolivia are among the 42 countries whose governments have either restricted or outlawed the use of digital currency exchanges or restricted banks' ability to deal with crypto. The number of countries and authorities that have overtly or tacitly banned cryptocurrencies has more than doubled since the group first issued research on the subject in 2018. According to governments that have banned cryptocurrency, criminals are using it to transfer money to criminals, and the expansion of crypto might undermine their financial systems. Many governments, including the United States, are considering regulations for cryptocurrencies despite the fact that n...

This summer, the Fed will take another step toward creating a digital money

This summer, the Federal Reserve will publish a research paper that examines the possibility of a central bank digital currency. 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. Despite the fact that the central bank did not announce any particular plans for the currency, Chairman Jerome Powell acknowledged advancements in payments technology and stated that the Fed has been "actively monitoring and responding" to those developments. 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...
