context.Context) (*big.Int, error)\n    \n    // Block operations\n    BlockByNumber(ctx context.Context, num *big.Int, fullTx bool) (*Block, error)\n    BlockByHash(ctx context.Context, hash []byte, fullTx bool) (*Block, error)\n    \n    // Account operations\n    Balance(ctx context.Context, addr []byte, block *big.Int) (*big.Int, error)\n    GetCode(ctx context.Context, addr []byte, block *big.Int) ([]byte, error)\n    \n    // ... and more\n}\n```\n\n### Data Structures\n\nAll data structures mirror the official Geth implementation:\n\n- **Block**: Complete block with header, transactions, ommers, withdrawals\n- **BlockHeader**: Detailed header with all Ethereum fields\n- **Transaction**: Comprehensive transaction with EIP support\n- **Receipt**: Transaction receipt with
