A minimalist blockchain runtime written in Rust, designed to explore core blockchain concepts like balances, system state, extrinsics, and proof-of-existence claims. Inspired by Substrate’s architecture.

• ✅ Generic runtime using traits and macros
• ✅ Balance pallet with safe arithmetic and transfer logic
• ✅ System pallet with block number and nonce tracking
• ✅ Proof-of-Existence pallet (claim & revoke)
• ✅ Block execution with extrinsics
• ✅ Macro-based dispatch system: #[call], #[runtime]
