Event Bitcoin Whitepaper
Bitcoin block and chain design — headers, Merkle trees, and chain selection
How Bitcoin blocks are structured, how Merkle trees commit transactions to block headers, and how the most-work chain selection rule resolves forks.
Event Bitcoin Whitepaper
Bitcoin consensus design — proof of work, difficulty adjustment, and fork handling
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.
Event Bitcoin Whitepaper
Bitcoin cryptography design — keys, signatures, hashes, and address derivation
How Bitcoin uses elliptic-curve keys, digital signatures, hash functions, and deterministic derivation to secure ownership without trusted third parties.
Event Bitcoin Whitepaper
Bitcoin P2P network design — node discovery, message relay, and block propagation
How Bitcoin nodes find each other, exchange transactions and blocks, and resist network-level attacks across the P2P gossip layer.
Event Bitcoin Whitepaper
Bitcoin security model — attack surfaces, trust assumptions, and defense layers
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.
Event Bitcoin Whitepaper
Bitcoin storage design — block database, UTXO set, and chain state management
How Bitcoin Core persists blocks, maintains the UTXO set, indexes chain state, manages the mempool, prunes historical data, and bootstraps via assumeUTXO.
