Bundle Simulation

The process of executing a Jito bundle against the current chain state in a sandboxed environment to verify that all transactions in the bundle succeed and produce the expected outcome before committing real tips and submitting to the Block Engine. Simulation catches issues like stale state, insufficient balances, or failed arbitrage conditions, preventing searchers from paying tips for bundles that would fail on-chain. Jito provides simulateBundle API endpoints for this purpose.

Ramo

Bundle (Jito)

An atomic group of up to five transactions submitted together through Jito's Block Engine, where either all transactions land in sequence or none do, enabling MEV strategies that depend on guaranteed transaction ordering without risk of partial execution. Bundles are submitted with a tip to incentivize the leader to include them; the Block Engine simulates bundles, selects the most profitable ones, and forwards them to the Jito-enabled leader. Bundles land at the top of a block before standard transactions, giving searchers execution priority.

Block Engine (Jito)

Jito's off-chain infrastructure component that receives bundles from MEV searchers, simulates them against the current chain state to verify profitability and validity, and forwards the highest-value bundles to the current Jito-enabled leader just before block production. The Block Engine operates as a low-latency relay that continuously tracks the leader schedule and streams winning bundles in real time, acting as a private transaction ordering marketplace sitting between searchers and validators.

Jito (MEV Infrastructure)

A Solana MEV infrastructure project by Jito Labs that operates a modified validator client (jito-solana), a Block Engine for bundle simulation and routing, and a tip distribution program that collects and distributes MEV tips to staked validators. Jito's client is run by a supermajority of Solana's stake-weighted validators, making its bundle and tip market the de-facto MEV layer for the network. Jito also operates a restaking and liquid staking protocol (JitoSOL) using proceeds from MEV tip redistribution.

Confirmation Time

The wallclock duration between a transaction being submitted and achieving a desired commitment level. On Solana, processed confirmation takes ~400ms (leader executes), confirmed (optimistic) takes ~400ms-1s (supermajority votes), and finalized (rooted) typically takes 26-32 slots (~10-13 seconds). Actual confirmation time varies with network congestion, leader distance, and transaction priority fee.

Redebanking-stage

Banking Stage

The critical TPU pipeline stage in which Solana validators execute transactions, update account state, and produce entries that will be packed into a block. Banking stage receives forwarded transactions from the fetch and sigverify stages, acquires account locks via the scheduler, runs transactions through the SVM, and writes results to the accounts database. It is the computational heart of block production and is where compute unit limits, priority fee ordering, and parallel execution all converge.

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.

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.

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.
