How the Bitcoin ecosystem layers above and around the base chain: Lightning payment channels, federated sidechains, L1 envelope extensions, and mining pool architectures.
Bitcoin's threat model mapped end-to-end: what the protocol trusts, what it defends against, how each attack is countered, and where open risks remain.
How Bitcoin nodes agree on a single chain: SHA-256d proof of work, the difficulty adjustment algorithm, block validation rules, fork resolution, and probabilistic finality.
How Bitcoin blocks are structured, how Merkle trees commit transactions to block headers, and how the most-work chain selection rule resolves forks.
Deep-dive into Bitcoin's transaction layer: UTXO lifecycle, transaction structure, Script evaluation, ECDSA and Schnorr signatures, SegWit, and Taproot.
High-level system overview of Bitcoin's architecture, layer model, and data flow. Entry point to a 12-page design-document series covering every major subsystem.
Beginner's visual guide to Bitcoin — 30 terms across 8 chapters, each with a diagram. Coins as UTXOs, transactions as flows, blocks chained by hashes, mining, mempool, longest-chain consensus.
He built RPOW, received the first Bitcoin transaction, and lived blocks from Dorian Satoshi Nakamoto. The evidence for Hal Finney as Satoshi, weighed.
He conceived Bit Gold, and three of the four most-cited stylometric studies place him first. The evidence for Nick Szabo as Satoshi, weighed.
Bitcoin v0.1 reuses one cypherpunk primitive (PoW from Hashcash), borrows general CS components (Merkle trees, linked timestamping, ECDSA), and synthesizes the rest (UTXO, mining, 21M cap, P2P).
Hashcash's inventor and the first person Satoshi contacted. In April 2026 the NYT named him the closest stylometric match among 620 cryptography-mailing-list writers. The evidence, weighed.
