Easy

1. What is Solana?High-throughput, low-latency execution and Proof of History.
2. The Accounts ModelUnderstanding Solana's fundamental data unit.
3. Programs and Executable DataBPF Loader and on-chain program deployment.
4. SOL and LamportsNative token denominations and fractional precision.
5. Rent and Rent ExemptionStorage fee mechanics and permanent account allocation.
6. Program Derived Addresses (PDAs)Deterministic addresses without private keys.
7. Cross-Program Invocations (CPIs)Composability and inter-program calls.
8. Instruction Data and Serialization FormatsBorsh vs Bytemuck vs Zero-Copy serialization payloads.
9. The System ProgramCreating accounts and managing native SOL.
10. SBF Virtual Machine & ArchitectureRegisters, stack limits, and execution mechanics.
11. Compute Budget and Units (CUs)Managing transaction compute and priority.
12. Transaction Atomicity and InstructionsAll-or-nothing execution of multi-instruction transactions.
13. Sysvars: Clock, Rent, SlotHistoryAccessing cluster state on-chain.
26. Anchor: declare_id! & #[program]Pinning program addresses and routing instructions.
27. Anchor: Account Validation & #[derive(Accounts)]Declarative struct validation.
28. Anchor: Signer<'info> & #[account(mut)]Enforcing signatures and mutable write locks.
29. Anchor: #[account(init, ...)]Creating and funding accounts in one declarative step.
30. Anchor: 8-Byte Discriminator and Space CalculationAccounting for Anchor headers.
