Q1 2027Solana Foundation governance decisions on client diversity
Current obstacles
Client monopoly riskHigh Jito client adoption (47%) concentrates block-building power. Further adoption could create a single point of failure for Solana.
Searcher information asymmetrySearchers know their strategies but validators do not. Validators cannot verify if a searcher is front-running or causing harm.
Physics limits
Solana block time and throughputSolana targets 400 milliseconds per block. Preconfirmations lock in transactions on that timescale, limiting flexibility.
Network topology and latencyLatency advantage depends on proximity to validators. Validators in better-connected regions earn more, favoring centralization.
How it works
4 parts
Preconfirmation stream
Validators broadcast transaction ordering
Validators using Jito client broadcast early, low-latency transaction data to subscribers (searchers, traders). They commit to ordering within the next block.
Searcher subscriptions
Pay for MEV opportunities
Searchers subscribe to the preconfirmation stream and pay validators for ordering guarantees. 10ms latency advantage is enough for profitable arbitrage.
Revenue distribution
Split among ecosystem
Revenue splits: 35% to validators (by stake), 35% to Jito DAO, 30% to infrastructure providers.

MEV infrastructure, Solana block building
Jito Labs develops MEV and block-building infrastructure for Solana. Its core product, Jito Block Assembly Marketplace (BAM), enables validators to commit to transaction ordering in advance and earn MEV revenue. Preconfirmations launched on Solana mainnet in September 2026.
Jito BAM preconfirmations launched September 9, 2026, covering 34% of Solana's validator stake with 10ms latency edge.
The Jito client is used by 47% of Solana validators, making Jito the de facto block-building layer. Validators earn MEV revenue.
Jito raised $72.1M across five funding rounds. a16z Crypto led $50M Series B in October 2025 at $1B valuation.
