Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. Thereโs another optionโsecure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secureโlike Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
How Does Bitcoin Mining Work?
Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. Itโs a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. โThis is how new coins are createdโ and new transactions are added to the blockchain, says Okoro.
