The day quantum computers break Bitcoin — will the world end?

Which Bitcoin assets are at risk from a cryptographically relevant quantum computer, and what the timeline and migration debate around post-quantum cryptography looks like.

Luke Dashjr — Long-tenured Bitcoin Core contributor, Bitcoin Knots maintainer, and Ocean mining pool co-founder (dates unknown)

American developer (luke-jr), long-tenured Bitcoin Core contributor. Maintains Bitcoin Knots; co-founded Ocean mining pool (2023). Suffered a $3.5M+ wallet theft in late 2022 (compromised PGP key).

The day 184 billion BTC was minted — the centralization paradox, soft-fork rescue, and a 5-hour response

Structural reading of the 2010-08-15 overflow incident — soft-fork rescue mechanics, why a 5-hour response was only achievable then, transaction-shape forensics, and the centralization paradox.

Bitcoin architecture evolution — Satoshi era v0.1 vs modern v27+ baseline

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 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.

Bitcoin monetary design — issuance schedule, fee market, and incentive structure

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.

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.

Bitcoin transaction design — UTXO model, Script, and signature schemes

Deep-dive into Bitcoin's transaction layer: UTXO lifecycle, transaction structure, Script evaluation, ECDSA and Schnorr signatures, SegWit, and Taproot.

Bitcoin wallet and interface design — key management, transaction construction, and RPC

How Bitcoin Core manages keys, constructs transactions, selects coins, estimates fees, and exposes functionality through RPC, REST, and ZMQ interfaces.

Bitcoin system design overview — architecture, data flow, and design-document index

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 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.

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.
