Leitura rápida

Comece pela explicação mais curta e útil antes de aprofundar.

The aggregate effect on Solana network resources — primarily compute units and account space — introduced by Token Extensions (Token-2022), which adds on-chain extension data and additional CPI calls compared to the original SPL Token program. Tokens with multiple extensions (e.g., transfer fees + confidential transfers + interest-bearing) require significantly more compute budget per instruction, affecting transaction size, CPI depth, and priority fee calculations. Developers must account for the higher CU consumption of Token-2022 instructions when setting compute unit limits and priority fees to ensure reliable transaction landing.

Token-2022 (Extensões de Token)

The next-generation token program (TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb) that extends SPL Token with configurable extensions. Extensions include transfer fees, confidential transfers, transfer hooks, permanent delegate, non-transferable tokens, interest-bearing tokens, metadata, and more. Token-2022 is backwards-compatible with SPL Token for basic operations.

Unidades de Computação (CU)

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.

TPS (Transações por Segundo)

The rate at which a Solana cluster processes and commits transactions; Solana's theoretical maximum exceeds 65,000 TPS due to its parallel execution model, though real-world sustained throughput on Mainnet Beta typically ranges from 2,000–5,000 non-vote TPS under normal load. Vote transactions (used for consensus) make up a significant portion of all on-chain activity and are counted separately. High TPS is enabled by Proof of History timestamps, Sealevel parallel execution, and Gulf Stream mempool-less forwarding.

Tip (Jito)

A SOL payment made by a searcher to a Jito tip account as part of a bundle submission, used to compensate the leader validator for including the bundle at a preferred position in the block. Tips flow to Jito's on-chain tip distribution program, which redistributes a portion to staked validators (including delegators) proportional to their stake weight, aligning validator incentives with MEV facilitation. Tips are separate from and in addition to standard transaction priority fees.

Redenetwork-congestion

Network Congestion

A state in which the volume of transaction submissions to Solana leaders exceeds available block space or processing capacity, causing elevated transaction drop rates, increased time-to-confirmation, and rising priority fee requirements to land. Congestion is typically account-local (concentrated around hot accounts like popular DEX pools or NFT mints) rather than global, reflecting Solana's local fee market design. Mitigation strategies include increasing priority fees, submitting directly to the leader's TPU, routing through staked RPC nodes (SWQoS), and using Jito bundles.

Mainnet Beta

Solana's primary production cluster where real SOL and real economic activity occur; the "beta" designation reflects the network's ongoing protocol development despite being fully live since March 2020. It uses the same architecture as other clusters but with real validator stakes, live staking rewards, and permanent on-chain state. All production dApps, tokens, and NFTs exist on Mainnet Beta.

Rede

Devnet

A persistent public Solana cluster intended for application development and testing, running the same software version as Mainnet Beta but with no real economic value. Devnet SOL can be freely airdropped via the CLI or faucet APIs, and the ledger may be reset periodically by Solana Labs. Developers use Devnet to test programs and integrations before deploying to Mainnet Beta.

Rede

Testnet

A public Solana cluster used primarily by the Solana core team and validators to test new software releases, performance benchmarks, and network upgrades under real network conditions before they reach Mainnet Beta. Testnet SOL has no monetary value, and the ledger is reset more frequently than Devnet; it is less suitable for application development and more suited for validator operators validating their infrastructure.
