Nonce Account

A special account managed by the System Program that stores a durable nonce value, enabling transactions with extended or indefinite lifetimes. Normally, transactions reference a recent blockhash and expire after ~60-90 seconds. Nonce accounts replace the blockhash with a stored nonce that remains valid until explicitly advanced, enabling offline signing workflows, scheduled transactions, and custodial operations where signing and submission happen at different times.

Rama

Durable Nonce

A mechanism that replaces the short-lived recent blockhash in a transaction with a nonce value stored in a dedicated on-chain nonce account, allowing the transaction to remain valid indefinitely until it is used or the nonce is advanced. The nonce account stores the current nonce hash and an authority; the first instruction of any durable-nonce transaction must be AdvanceNonceAccount, which updates the nonce and invalidates the old one. Durable nonces are essential for workflows requiring offline signing, hardware security modules, or multi-party approval over extended time periods.

Programa del Sistema

The built-in native program (address: 11111111111111111111111111111111) responsible for creating new accounts, transferring SOL between accounts, allocating account data space, and assigning account ownership to programs. It is the only program that can create new accounts and is invoked in nearly every transaction.

Blockhash (Recent)

A 32-byte hash derived from the bank's state at a given slot, included in every Solana transaction to prove the transaction was created recently and to prevent replay attacks. A blockhash remains valid for approximately 150 slots (~60–90 seconds at normal slot times); transactions submitted with an expired blockhash are rejected outright. Clients must fetch a fresh blockhash before signing and ideally reuse it for as short a window as possible to maximize landing probability.

Par de Claves

A pair of a 32-byte Ed25519 private key and its corresponding 32-byte public key. Keypairs are used to sign transactions and derive account addresses. They are stored as 64-byte arrays (private + public concatenated) in JSON files by the Solana CLI. The private key should never be shared or exposed.

Modelo de Programaciónaccount-data

Account Data

The byte array stored in an account that holds program-specific state. Data is typically serialized using Borsh and must be explicitly allocated at account creation. The maximum data size is 10MB. Programs are responsible for defining and managing their own data layout, including discriminators for type identification.

Abrir término
Modelo de Programaciónbuffer-account

Buffer Account

A temporary account used during Solana program deployment to hold the program's ELF binary before it is written to the program data account. The deployer creates a buffer account, uploads the compiled SBF binary in chunks via the Upgradeable BPF Loader's Write instruction, and then issues a Deploy or Upgrade instruction that copies the buffer contents to the final program data account. Buffer accounts can be closed after deployment to reclaim rent.

Abrir término
Modelo de Programaciónclose-account

Close Account

The process of reclaiming an account's lamports and marking it for deletion. To close an account: transfer all lamports to a recipient, zero out the data, and (in Anchor) set the discriminator to a closed sentinel. The runtime garbage-collects zero-lamport accounts. Failing to zero data enables revival attacks.

Modelo de Programación

Cuenta

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.

Abrir término
Modelo de Programación

Programa

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).

Abrir término
Modelo de Programación

Instrucción

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.

Abrir término
Modelo de Programación

Transacción

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.
