@Jasmin Noe last man standing rn

No hashy hour today. Let’s do one next month!

Anthony is a wealth of knowledge 🪎✨

@Alan Soko such good questions 🎯🎯🎯 will meditate on Mount Satoshi and come back with answers for you in the Bitcoin Fundamentals curriculum dropping soon

@Alan Soko Hash — Cryptographic function that timestamps transactions into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the work. CPU — Processing power used by network nodes to perform the computational work required for proof-of-work and securing the network. The computer power has since evolved from basic CPU > GPU > now all mining is done with specialized silicone ASICs which are orders of magnitude more efficient Nodes — Computers running Bitcoin software that maintain copies of the blockchain, validate transactions, and reach consensus on the longest chain. Coin — A Bitcoin (or satoshi). Treated as a chain of digital signatures where each transaction proves ownership. Public/Private Keys — Digital signatures enabling peer-to-peer transactions. Public key = address others send to. Private key = proof of ownership and authorization to spend. Honest Chain — The longest chain of valid blocks built by nodes following protocol rules. The network accepts this as authoritative history. Binomial Random Walk — Probability model analyzing attack scenarios. Models the race between an attacker catching up to the honest chain versus honest miners extending it. Probability of catch-up decreases exponentially if the attacker falls behind. I’ll break these down in more detail across the modules.
