"content": "We just concluded week 6 of the Mastering Bitcoin live cohort. 📚\n\nThis week focused on understanding how the Bitcoin blockchain works and how new blocks are created through mining and consensus.\n\nParticipants explored the structure of the blockchain, including how blocks store transaction data, how blocks are linked together using cryptographic hashes, and how the block header contains the key information used to secure and validate each block.\n\nThe cohort also examined merkle trees and how they efficiently organize transactions inside a block, allowing nodes to verify transactions without needing to download the entire blockchain.\n\nIn addition, we studied the mining⛏️ process and Bitcoin’s proof‑of‑work consensus mechanism, learning how miners compete to solve cryptographic puzzles, how difficulty adjustments keep block production consistent, and how block rewards and transaction fees incentivize miners to secure the network.\n\nWe also discussed how consensus emerges across the distributed network, ensuring that all nodes agree on the valid chain while maintaining Bitcoin’s decentralized and trustless design.\n\nThroughout the week, participants reviewed the assigned materials, collaborated with their partners, and worked through discussion questions to deepen their understanding.\n\nDuring the live session, participants shared insights with the group and the faculty led the discussion on key ideas from the readings.\n\nhttps://npub1353snusdats4lpgwel4frhlmm05w6md2u89gss0dcdzamlhm2yas25gajp.blossom.band/c28cff2cf587938b0d3e91ecfdebdac44103c8aa5d9db430eec263f0a4825689.jpg\n https://npub1353snusdats4lpgwel4frhlmm05w6md2u89gss0dcdzamlhm2yas25gajp.blossom.band/b8d87bd430fb1458c7b0d17d870cbbd0a0467e5c49013ffd3636b36d77048094.jpg\n https://npub1353snusdats4lpgwel4frhlmm05w6md2u89gss0dcdzamlhm2yas25gajp.blossom.band/b7531bb25493b290b4e2e2bb1408ff2b4fb6463491cac626edb1eba66299f8c1.jpg\n https://npub1353snusdats4lpgwel4frhlmm05w6md2u89gss0dcdzamlhm2yas25gajp.blossom.band/6f3d7ffb37a2ba2e398bd5caf8f9ff9b61444c109fec25f5d230b030d465b357.jpg",
