New features: - Enhanced bootstrap.sh with blockchain download option - create-blockchain-snapshot.sh for creating compressed snapshots - BOOTSTRAP.md documentation Benefits for Raspberry Pi users: - Download pre-synced blockchain (~500MB compressed) - Skip days/weeks of initial sync - Start mining immediately from latest block - Interactive installer asks: bootstrap or sync from scratch Snapshot creation: - Safely stops daemon - Excludes wallet.dat (security) - Compresses to ~70% original size - Includes checksums and metadata TODO: Create first snapshot from DNS2 and host on GitHub releases
