Explanation:

Facebook has officially announced the details of its new global cryptocurrency called Libra.

• Consumers can pseudonymously buy/cash out their Libra online or even at local exchange points (ex- grocery stores), and can spend it using interoperable 3rd-party wallet apps or Facebook’s own Calibra wallet.
• Libra is maintained by nodes which are servers that help operate blockchain.
• Every Libra payment is permanently inscribed into Libra Blockchain which is a cryptographically authenticated database that acts as public online ledger and designed in a way to handle 1000 transactions/second.
