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.
Telegram auto-delete message, expiring invites, and more
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsAppโs privacy policy and now the company is adopting features that were already part of its competitorsโ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegramโs encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete wonโt remove every message though; if a message was sent before the feature was turned on, itโll stick around. Telegramโs competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
