"content": "We just concluded week 5 of the Mastering Bitcoin live cohort. 📚\n\nThis week focused on transaction fees and the structure of the Bitcoin network.\n\nParticipants explored how Bitcoin transactions compete for block space through fee rates, how wallets estimate appropriate fees, and mechanisms such as Replace‑By‑Fee (RBF) and Child Pays for Parent (CPFP) that allow transactions to be confirmed faster when needed.\n\nThe cohort also examined how the Bitcoin peer‑to‑peer network functions, including how nodes connect and discover peers, how blocks and transactions propagate across the network, and the roles of full nodes, lightweight clients, and mining nodes.\n\nWe further explored mempools, block relay, and how different node types interact to maintain the decentralized network.\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 led a short discussion on key ideas from the readings.\n\nhttps://npub1353snusdats4lpgwel4frhlmm05w6md2u89gss0dcdzamlhm2yas25gajp.blossom.band/c7534ef100c282b870c1dc1bb5a7498ef8c13c5748bdea000a119b8947c500a1.jpg\n https://npub1353snusdats4lpgwel4frhlmm05w6md2u89gss0dcdzamlhm2yas25gajp.blossom.band/851a786b33aaa89141c739c1583589a0ac40cd2a93b1a871b75b4b77eb280426.jpg\n https://npub1353snusdats4lpgwel4frhlmm05w6md2u89gss0dcdzamlhm2yas25gajp.blossom.band/f08580c690a7509da92011aa14fe6381db510c9631818f0827f0822155f6f8fa.jpg\n https://npub1353snusdats4lpgwel4frhlmm05w6md2u89gss0dcdzamlhm2yas25gajp.blossom.band/9dd46927b0faeb25135c4e341d1b2d5f3f313b8625888c33d2e74835b804b813.jpg",
