In this HashrateUp Focus episode, Jesse breaks down one of the most fundamental concepts in Bitcoin mining: what a hash actually is.Building on the previous Focus episode about the dice-roll analogy and difficulty adjustment, this episode explains how SHA256 hashing works and why Bitcoin mining is essentially large-scale brute-force guessing.You’ll learn:What a hash is and why it’s one-wayHow SHA256 is used everywhere on the internetWhy miners make trillions of guesses per secondWhat a nonce is and why it keeps changingWhy valid Bitcoin blocks need hashes with leading zerosHow proof of work is verified by the networkThis episode is designed to give you an intuitive, practical understanding of how hashing powers Bitcoin mining, without unnecessary math or jargon.If you’re new to Bitcoin mining, make sure to listen to the previous Focus episode first — both episodes are meant to be consumed together.🛠 Sponsored byHashbranch – Hosting & hardware made simpleCode: HASHRATEUP100https://hashbranch.comSoloMining.de – Home & solo mining made easyCode: HASHRATEUPhttps://solomining.de📲 HashrateUp Hardware DealsTelegram: https://t.me/hashrateup🌐 Website: https://hashrateup.com🐦 Twitter: https://twitter.com/HashrateUp📸 Instagram: https://www.instagram.com/hashrateupbtc/🎵 TikTok: https://www.tiktok.com/@hashrateup💼 LinkedIn: https://www.linkedin.com/company/hashrateup
