TPU Client

A client library that sends transactions directly to the current leader validator's Transaction Processing Unit (TPU) port over QUIC, bypassing the standard RPC sendTransaction relay for lower latency and higher landing probability. The Solana SDK's TpuClient resolves the current leader from the leader schedule, establishes a QUIC connection, and forwards signed transactions directly. This approach is used by MEV searchers, high-frequency traders, and latency-sensitive applications that need the fastest possible path to block inclusion.

Ramo

TPU (Unidade de Processamento de Transações)

Transaction Processing Unit—the pipeline within a leader validator that ingests, verifies, and executes transactions. The TPU has stages: fetch (receive packets via QUIC), sigverify (verify Ed25519 signatures), banking (execute against current bank state), and broadcast (shred and send via Turbine). Non-leader validators forward transactions to the current leader's TPU.

QUIC Protocol

The UDP-based transport protocol adopted by Solana as its primary transaction submission protocol, replacing raw UDP to provide congestion control, multiplexed streams, and connection-level flow control without TCP's head-of-line blocking. Solana's TPU (Transaction Processing Unit) accepts client transactions over QUIC, allowing the leader to apply back-pressure and drop connections from misbehaving senders. QUIC integration with SWQoS allows leaders to enforce stake-weighted bandwidth limits at the transport layer.

Stake-Weighted QoS (SWQoS)

Transaction Landing

The outcome of a transaction being successfully included and confirmed in a Solana block, as opposed to being dropped, expiring, or failing simulation. Landing probability is influenced by priority fee competitiveness, blockhash freshness (must be within ~150 slots of creation), submission routing (direct to leader vs. RPC rebroadcast), and network congestion on the accounts involved. Developers optimize landing rates by using current-leader TPU endpoints, setting appropriate priority fees, and preflight-checking transactions before submission.

TPU Forwarding

The mechanism by which non-leader validators forward incoming transactions to the current slot leader's TPU port so they can be included in the next block. When a validator receives transactions during slots it is not leading, it relays them to the upcoming leader(s) based on the leader schedule. This forwarding behavior, combined with Gulf Stream's look-ahead, means transactions can reach the leader before its slot begins, reducing confirmation latency.

Redethin-client

Thin Client

A blockchain client that trusts the cluster's communication without independently verifying transaction validity, relying on RPC responses from validators for all state queries. Thin clients are the simplest integration method — most dApp frontends and wallet interfaces operate as thin clients by trusting their configured RPC provider to return accurate data.

Redelight-client

Light Client

A blockchain client that verifies a moderate amount of cluster data to confirm transaction validity without replaying the full ledger or maintaining complete account state. Light clients download block headers and use Merkle proofs or validator attestations to verify specific transactions or account states, trading full trustlessness for dramatically reduced resource requirements.

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.

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.
