Cross-cutting architecture comparison across every subsystem: Satoshi's v0.1 (January 2009) side by side with modern Bitcoin Core v27+, with split diagrams and domain tables.
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 uses elliptic-curve keys, digital signatures, hash functions, and deterministic derivation to secure ownership without trusted third parties.
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.
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.
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).
Peter Todd announced OpenTimestamps, an open-source infrastructure using the Bitcoin blockchain to timestamp unlimited documents per transaction via Merkle tree aggregation.
