“Developing Blockchain Software”
summary
Explains how Bitcoin (UTXO, mining, longest-chain) and Ripple (2011 consensus ledgers, arbitrary assets) solve double‑spend and cross‑ledger payments, and why C++ is used: move semantics, lambdas, compile‑time polymorphism and header‑only libraries for performance and determinism. Describes PBFT/Byzantine tradeoffs for high‑value atomicity, Interledger escrow that locks then releases across ledgers, a cache strategy that pins hot objects with strong/weak pointers, and NewDB, a key‑value store that targets one IO for misses and two IOs for hits.
