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.

Plain meaning

Start with the shortest useful explanation before going deeper.

Mental model

Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.

Think of it as a building block that connects one definition to the larger Solana system around it.

Technical context

Place the term inside its Solana layer so the definition is easier to reason about.

Clusters, nodes, MEV actors, routing, and operating environments.

Why builders care

Turn the term from vocabulary into something operational for product and engineering work.

This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

Concept graph

See the term as part of a network, not a dead-end definition.

These branches show which concepts this term touches directly and what sits one layer beyond them.

Branch

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.

Branch

RPC (Remote Procedure Call)

The JSON-RPC 2.0 protocol interface through which clients communicate with Solana nodes to query chain state, submit transactions, and subscribe to events. Solana exposes a rich set of HTTP and WebSocket endpoints (e.g., getAccountInfo, sendTransaction) that abstract direct peer-to-peer network participation, making RPC the primary integration point for wallets, dApps, and indexers.

Branch

RPC Node

A Solana full node that stores ledger state and serves JSON-RPC and WebSocket requests from clients without participating in consensus or voting. RPC nodes must replay every transaction to maintain an accurate account state database, and high-throughput deployments typically run dedicated RPC nodes with large SSDs, high RAM (256 GB+), and high-bandwidth network connections to handle concurrent client load without impacting validator performance.

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.

Networktpu-client

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.

Network

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.

Network

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.

Network

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.

Network

TPS (Transactions Per Second)

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.
