Diagnostic output from programs using `msg!()` (Anchor) or `sol_log()` (native). Logs appear in transaction metadata and explorer UIs. Each log call costs compute units (~100 CU base + data length). Logs are limited to 10KB per transaction. Anchor events also emit as base64-encoded log messages.

A measure of computational resources consumed by transaction execution, analogous to gas on Ethereum. Each BPF instruction costs CU; syscalls have predefined CU costs (e.g., SHA-256: 85 CU base + per-byte). Default per-instruction limit is 200,000 CU; max per-transaction is 1,400,000 CU. Priority fee cost = CU price × CU consumed.
Executable code deployed on-chain, equivalent to a smart contract on other blockchains. Programs are stateless—they store no data themselves but read/write data in separate accounts they own. Programs are compiled to SBF bytecode and loaded via the BPF Loader. Every program has a unique Program ID (its account's public key).

The account that stores the actual SBF ELF bytecode for an upgradeable program. It is separate from the program's main account (which just points to the program data). This separation allows the bytecode to be swapped during upgrades while the program ID stays the same. The program data account also stores the upgrade authority pubkey.
The public key that uniquely identifies a deployed program. It's the address of the program's executable account. When invoking a program, the instruction specifies the program_id. Anchor's `declare_id!()` macro hardcodes the expected program ID. PDAs are derived relative to a program's ID, tying state to the specific program.
A native Solana program (address: ComputeBudget111111111111111111111111111111) that allows transactions to configure their compute resource limits. It provides two key instructions: SetComputeUnitLimit (set the max CU a transaction can consume, up to 1.4M) and SetComputeUnitPrice (set the micro-lamport price per CU for priority fees). These instructions must appear before any program instructions in the transaction.

The fundamental data storage unit on Solana. Every piece of state is stored in an account identified by a 32-byte public key. Accounts hold a lamport balance, an owner program, a data byte array (up to 10MB), and an executable flag. Only the owning program can modify an account's data, but anyone can credit lamports to it.

A single operation within a transaction that invokes a program. An instruction specifies: (1) the program ID to call, (2) an array of account metas (pubkey, is_signer, is_writable), and (3) an opaque data byte array. Programs decode the instruction data to determine which operation to perform.
An atomic unit of execution containing one or more instructions, a recent blockhash, and one or more signatures. All instructions in a transaction execute sequentially and atomically—if any instruction fails, the entire transaction reverts. Transactions have a 1,232-byte size limit (matching IPv6 MTU) and a default 200,000 CU budget.
