Block interval, reward schedule and difficulty adjustment cannot be selected independently. Short blocks increase propagation pressure and orphan risk, while a slow or unsuitable retarget algorithm can leave a small network stalled after miners depart. Simulations cover abrupt hash-rate changes and manipulated timestamp boundaries.
Genesis data, message magic, default ports, address prefixes and seed lists establish network identity. We verify those values across daemon, wallet and test tooling, and separate testnet from mainnet at every layer. Any premine is encoded transparently, with destinations and amounts available for independent verification.
