• Facebook recently unveiled a digital currency called Libra as the company seeks to make its ads more valuable by enabling smoother transactions and payments online, particularly among those without credit cards or bank accounts. It will use the same security and record-keeping principles as Bitcoin, the most popular digital currency system today. But unlike Bitcoin, Libra is backed by several traditional financial companies, including PayPal, Visa and Mastercard, and will base its value on multiple real-world currencies such as the US dollar and the euro.
• What is a cryptocurrency? Cryptocurrency is a form of digital cash that uses encryption technology to make it secure. Cryptocurrencies exist not as physical bills or coins but rather as lines of digitally signed computer code. Records are typically kept on ledgers known as blockchain. Although it‘s possible to trace bitcoins and some other cryptocurrencies as they are spent, owners of accounts behind the transactions aren‘t necessarily known. That makes such currencies a favourite among certain cybercriminals. But it is sometimes possible to tie cryptocurrency transactions to a real person who has cashed out digital coinage into a traditional currency.
• Monero is a secure, private and untraceable currency. This open-source cryptocurrency was launched in April 2014. he development of this cryptocurrency is completely donation-based and community-driven. Monero has been launched with a strong focus on decentralization and scalability, and it enables complete privacy by using a special technique called ring signatures. With this technique, there appears a group of cryptographic signatures including at least one real participant, but since they all appear valid, the real one cannot be isolated. Because of exceptional security mechanisms like this, monero has developed something of an unsavory reputation; it has been linked to criminal operations around the world.
