How the Bitcoin ecosystem layers above and around the base chain: Lightning payment channels, federated sidechains, L1 envelope extensions, and mining pool architectures.
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 Core persists blocks, maintains the UTXO set, indexes chain state, manages the mempool, prunes historical data, and bootstraps via assumeUTXO.
How Bitcoin Core manages keys, constructs transactions, selects coins, estimates fees, and exposes functionality through RPC, REST, and ZMQ interfaces.
How Bitcoin uses elliptic-curve keys, digital signatures, hash functions, and deterministic derivation to secure ownership without trusted third parties.
How Bitcoin's 21 million cap emerges from a geometric halving series, how block rewards transition from subsidy to fees, and how the incentive model sustains honest mining.
How Bitcoin nodes find each other, exchange transactions and blocks, and resist network-level attacks across the P2P gossip layer.
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.
Start here if you know nothing about Bitcoin beyond the price. A five-part guide to what a bitcoin is, who keeps the record, how new coins appear, and why no one can cheat it.
